ABSTRACT Effluent from fish farming with saline water is a source of water, also rich in organic matter and nutrients, that can be used in irrigation of cultivated plants and even fully or partially replace mineral fertilization. The objective was to evaluate the growth, biomass production and quality of P. maximum cultivars fertigated with fish farming effluent in a greenhouse experiment, using a randomized block design with eight replicates. Treatments were arranged in a split-split-plot scheme, with three irrigation managements in the plot (irrigation with public-supply water, irrigation with public-supply water + conventional fertilization, and irrigation with fish farming effluent), three cultivars of P. maximum (Tanzania, Mombasa, and Massai) in the sub-plot, and four cutting times in the sub-sub-plot (45, 90, 135, and 180 days after sowing). Plant height, number of tillers, production of fresh biomass, neutral detergent fiber, acid detergent fiber, ether extract, crude protein, dry matter, and mineral matter contents were analyzed. The highest growth, production, and quality of P. maximum grass occurs when irrigated with public-supply water and under conventional NPK fertilization. Fertigation with fish farming effluent reduces the growth and production of P. maximum grass, but allows obtaining better quality forage. It is possible to irrigate P. maximum grass using fish farming effluent with satisfactory yields. The growth of cv. Massai was more sensitive to irrigation with fish farming effluent than those of the cultivars Tanzania and Mombasa. nutrients fertilization P experiment replicates splitsplitplot split scheme publicsupply public supply effluent, , effluent) Tanzania, (Tanzania Mombasa subplot, subplot sub plot, sub-plot subsubplot 45, 45 (45 90 135 18 sowing. sowing . sowing) height tillers fiber extract protein analyzed forage yields cv 4 (4 9 13 1 (

ABSTRACT Considering the importance of evaluating the compatibility between the exploration system usually used in the Caatinga and the vegetation regeneration process, this study aimed to evaluate the feasibility of recovering structural parameters in an experimental unit subjected to different management systems aged 9, 12, 16, 20 and 26 years post-exploitation. The area was subjected to clearcutting (CC) regimes and three types of selective cuttings (SC1 – selective cutting 1, cut of trees with diameter at the base – DAB < 15 cm; SC2 – selective cutting 2, cut of trees with DAB > 10 cm; and SC3 – selective cutting 3, cut of trees with DAB between 5 and 10 cm). In permanent plots of 20 m × 20 m, individuals with a circumference at breast height (CBH) ≥ 6 cm and a total height greater than 1.0 m were measured. Over the years of monitoring, the CC presented the lowest values of density, dominance, and volume, not obtaining a recovery in basal area and volume even after 26 years of regeneration. Treatments SC2 and SC3 stood out regarding recovery of the original woody biomass stock, presenting values higher than the original ones and indicating that the initial data did not correspond to the site's maximum potential. The forest dynamics pointed to the insufficiency of the 15-year clearcutting cycle in terms of recovering this region forest composition and structure. process 9 12 16 2 postexploitation. postexploitation post exploitation. exploitation post-exploitation (CC SC1 SC (SC 1 3 cm. . cm) CBH (CBH 0 1. measured monitoring density dominance stock sites site s potential 15year year structure

RESUMO Considerando a importância de se avaliar a compatibilidade entre o sistema de exploração usualmente empregado na Caatinga e o processo de regeneração da vegetação, este estudo objetivou avaliar a viabilidade de recuperação dos parâmetros estruturais em uma unidade experimental submetida a diferentes sistemas de manejo com idades de 9, 12, 16, 20 e 26 anos pós-exploração. A área foi submetida aos regimes de corte raso (CR) e três tipos de cortes seletivos (SC1 – corte seletivo 1, de árvores com diâmetro na base – DNB < 15 cm; SC2 – corte seletivo 2, de DNB > 10 cm; e SC3 – corte seletivo 2, de DNB entre 5 e 10 cm). Em parcelas permanentes de 20 m × 20 m, foram mensurados os indivíduos com CAP ≥ 6 cm e altura total superior a 1,0 m. Ao longo dos anos de monitoramento, o CR apresentou os menores valores de densidade, dominância e volume, não obtendo recuperação em área basal e volume mesmo após 26 anos de regeneração. Os tratamentos SC2 e SC3 se sobressaíram quanto à recuperação do estoque original de biomassa lenhosa, apresentando valores superiores aos originais e indicando que os dados iniciais não correspondiam ao potencial máximo do sítio. A dinâmica florestal apontou à insuficiência do ciclo de corte raso de 15 anos quanto à recuperação da composição e estrutura florestal nesta região. vegetação 9 12 16 2 pósexploração. pósexploração pós exploração. pós-exploração (CR SC1 SC (SC 1 cm. . cm) 0 monitoramento densidade lenhosa sítio região

ABSTRACT The complicated combined impacts of multiple parameters that affect the cutting process might make it challenging to describe burrs generated during face milling operations. The objective of the work is to study the influence of turning parameters such as depth of cut, spindle speed, and feed on three output performances such as machining time, surface roughness, and burr height. The three turning input parameters and three output turning performances are considered for machining three different materials, such as stainless steel, low-carbon steel, and high-carbon steel. The experimental design is planned as per the box-behnken design for six types of materials. Tungsten carbide is utilized as a cutting tool for all turning operations. Output parameters like machining time, burr height, and surface roughness are calculated. Machined (turned) samples are studied under the influence of a scanning electron microscope (SEM) for burr formation. Surface roughness is measured by the surface roughness meter, and machining time is calculated by the CNC machine itself. ANOVA is used to investigate and optimize machining parameters influence on output performances. The mathematical model for three output performances, such as machining time, burr height, and surface roughness, has been developed using response surface methodology. operations cut speed height materials steel lowcarbon low carbon highcarbon high boxbehnken box behnken turned (turned SEM (SEM formation meter itself methodology

RESUMO O manejo eficaz de florestas perturbadas requer um conhecimento adequado da dinâmica florestal. Neste estudo, avaliamos a mudança de uma floresta manejada em 18 parcelas permanentes de 1 hectare localizadas na floresta tropical de terra firme no leste da Amazônia (Brasil, Paragominas). Todos os indivíduos com diâmetro à altura do peito (DAP) ≥ 20 cm foram avaliados em duas avaliações separadas realizadas em 2006 e 2016. Os resultados indicam que, dez anos após a exploração, a floresta manejada apresenta um desequilíbrio nas taxas de recrutamento (1,54% ao ano) e mortalidade (2,23% ao ano), sugerindo que a floresta ainda está em processo de recuperação estrutural. No entanto, a biomassa mostrou um aumento após a exploração, atingindo 28,49 toneladas por hectare. As características das mudanças indicam que a floresta está em um processo silvigenético impulsionado pela exploração madeireira. Além disso, observamos que a floresta permanece ativa e possui potencial suficiente para uma nova produção de madeira no final do ciclo de corte, considerando as mesmas espécies e tamanhos de árvores. florestal estudo Brasil, Brasil (Brasil Paragominas.

ABSTRACT The effective management of disturbed forests requires adequate knowledge of forest dynamics. In this study, we assessed the changes in a managed forest using 18 permanent 1 ha plots located in a ‘terra firme’ tropical rainforest in the Eastern Amazon (Paragominas, Brazil). All individuals with a diameter at breast height (DBH) ≥ 20 cm were evaluated in two separate assessments conducted in 2006 and 2016. The results show that, ten years after logging, the managed forest exhibits an imbalance between recruitment (1.54% per year) and mortality (2.23% per year) rates, indicating that it is still in the process of recovering its structure. Nevertheless, biomass tended to increase after logging (28.49 tons per hectare). The characteristics of these changes suggest that the forest is undergoing a silvigenetic process driven by the effects of logging. Furthermore, our observations indicate that the forest remains active and has sufficient potential for new timber production at the end of the cutting cycle, considering the same species and tree sizes. dynamics study terra firme Paragominas, Paragominas (Paragominas Brazil.

SUMMARY OBJECTIVE: Female genital mutilation/cutting impacts over 200 million women globally and is linked to obstetric complications as well as long-term urogynecological and psychosexual issues that are frequently overlooked and inadequately addressed. This study aimed to assess the impact of female genital mutilation/cutting on urinary incontinence. METHODS: This cross-sectional study was conducted in the gynecology department of the Research Hospital located in the Nyala rural region of Sudan. The participants were interviewed to gather socio-demographic and background information. In addition, they received a thorough gynecological examination to evaluate the presence and type of female genital mutilation/cutting. The Incontinence Impact Questionnaire and the Urogenital Distress Inventory were applied to the group with female genital mutilation/cutting and the control group without female genital mutilation/cutting to evaluate urinary incontinence and related discomfort. Subsequently, the scores of both participant groups were compared. RESULTS: The study compared age, weight, height, BMI, gravida, parity, and sexual intercourse averages between groups. The mean Urogenital Distress Inventory-6 and Incontinence Impact Questionnaire-7 scores of individuals who underwent mutilation were higher than those of individuals who did not undergo mutilation (p<0.001). Notably, participants subjected to infibulation exhibited significantly higher average scores on both measures in contrast with the other groups (p<0.001). CONCLUSION: A higher proportion of mutilated participants, specifically those with infibulation, are afflicted with symptoms of incontinence.

ABSTRACT The purpose of this study was to evaluate the yield of dry matter (DM), crude protein (CP) and in vitro digestibility of dry matter (IVDMD) at four cutting heights and five maturity times of Pennisetum sp (Maralfalfa) during the periods of greatest and least precipitation in Pucallpa, Peru. Cuts were made at 0, 10, 20 and 30 cm height from the ground at 28, 35, 42, 49 and 56 days of regrowth. Plant height, number of stems, number, length and width of leaves, DM, CP and IVDMD yield were evaluated under a complete randomized design with a 4x5 factorial arrangement and 4 repetitions. The plant reached 120.5 cm in height at 56 days of regrowth. At the beginning of the growth period, it had 28 stems and 127 leaves, decreasing until it was established on 15 stems and 58 leaves after 56 days. In that same period the leaves grow up to 77.9 cm long and 2.3 cm wide. The DM performance increases when the cutting height is higher. The DM (kg/ha/cut) in the wet season (391.8 ± 386.1) was higher (p<0.05) than in the dry (235.5 ± 205.1). Plants cut at 30 cm height achieved the highest forage yields (DM kg/ha/cut) at 49 days (557.8 ± 322.8) and 56 days (537.5 ± 138.5) (p<0.05). The DM content of the plant was 15.9%. The highest CP content (13%) was obtained in 30 cm high cuts with 28 days of growth. The average PC was 9.645 ± 1.63 in the season of lowest precipitation and 11.94 ± 1.94 in the season of highest precipitation. The IVDMD value at 0 cm height at 28 days (59.5 ± 19.4%) was similar to that at the cuts at 35 days (59.5 ± 5.5%). It is concluded that maralfalfa can produce up to 557.8 ± 322.8 MS kg/ha/cut, and reach 11.0% CP, while the IVDMD reaches 59.5%, and it can be considered as an option to improve the diet of animals in the humid tropics of Pucallpa.

RESUMEN El propósito de este trabajo fue evaluar el rendimiento de materia seca (MS), proteína cruda (PC) y digestibilidad in vitro de la materia seca (DIVMS) en cuatro alturas de corte y cinco tiempos de madurez del Pennisetum sp (Maralfalfa) durante las épocas de mayor y menor precipitación en la zona de Pucallpa, Perú. Se realizaron cortes a 0, 10, 20 y 30 cm de altura con respecto al suelo a los 28, 35, 42, 49 y 56 días de rebrote. Se evaluó la altura de planta, número de tallos, número, largo y ancho de hojas, rendimiento de MS, PC y DIVMS bajo un diseño completo al azar con arreglo factorial de 4x5 y 4 repeticiones. La planta alcanzó 120.5 cm de altura a los 56 días de rebrote. Al inicio del crecimiento tuvo 28 tallos y 127 hojas disminuyendo hasta establecerse en 15 tallos y 58 hojas a los 56 días. En ese mismo periodo las hojas crecen hasta 77.9 cm de largo y 2.3 cm de ancho. El rendimiento de MS se incrementa cuando la altura de corte es mayor. La MS (kg/ha/corte) en época de mayor precipitación (391.8 ± 386.1) fue mayor (p<0.05) que en la época de menor precipitación (235.5 ± 205.1). Las plantas cortadas a 30 cm de altura lograron los mayores rendimientos de forraje (MS kg/ha/corte) a los 49 días (557.8 ± 322.8) y 56 días (537.5 ± 138.5) (p<0.05). El contenido de MS de la planta fue 15.9%. El mayor contenido de PC (13%) se obtuvo en cortes de 30 cm de altura con 28 días de crecimiento. El promedio de PC fue (9.645 ± 1.63) en la época de menor precipitación y (11.94 ± 1.94) en la de mayor precipitación. El valor de DIVMS a 0 cm de altura a los 28 días (59.5 ± 19.4%) fue similar que al corte a los 35 días (59.5 ± 5.5%). Se concluye que la maralfalfa puede producir hasta 557.8 ± 322.8 MS kg/ha/corte, y alcanzar 11.0% de PC, mientras que la DIVMS llega a 59.5%, pudiendo considerarse como una opción para mejorar la dieta de los animales en el trópico húmedo de Pucallpa.

Resumen Se evaluaron tres densidades de siembra, de&nidas por las distancias entre surcos, las cuales fueron: 70 cm (4375 kg biomasa ha-1), 85 cm (3750 kg biomasa ha-1) y 100 cm (3125 kg biomasa ha-1) y dos frecuencias de cosecha, a los 45 y 70 días después del corte de uniformidad (ddu). El experimento se realizó entre diciembre de 2020 y mayo de 2021 en la Finca Experimental de Santa Cruz de la Universidad de Costa Rica. Se utilizó un diseño en franjas, donde se cuanti&có la producción de biomasa fresca y seca, altura de planta, longitud de tallo y hojas, contenido de cloro&la, proteína cruda y número de nudos por tallo; para cada variable se efectuó un análisis de varianza. El uso de una distancia de siembra de 70 cm con una frecuencia de cosecha de 70 ddu, mostró valores mayores para biomasa fresca (p < 0,0001), producción de biomasa seca (p < 0,0068), altura (p < 0,0194) y longitud de tallo (p < 0,0093), en comparación con las otras combinaciones. Mientras que una combinación de distancia de siembra de 85 cm y una frecuencia de cosecha de 45 ddu presentó valores mayores para contenido de cloro&la (p < 0,0284) y porcentaje de proteína cruda (p < 0,0134). En edades de corte tempranas hubo mayor contenido de clorofila y de proteína cruda, mientras que en edades tardías hubo mayor producción de biomasa. Por productividad y por contenido de proteína, el Cuba OM-22 es una alternativa para bancos de forraje. Este trabajo formó parte del proyecto de investigación B8009 inscrito en Vicerrectoría de Investigación de la Universidad de Costa Rica, San José, Costa Rica.

Abstract Three planting densities, de(ned by the distances between rows, which were: 70 cm (4375 kg biomass ha-1), 85 cm (3750 kg biomass ha-1) and 100 cm (3125 kg biomass ha-1) and two harvest frequencies, at 45 and 70 days a)er the uniform cutting grass (auc) were evaluated. 'e experiment was carried out between December 2020 and May 2021 at the Santa Cruz Experimental Farm of the University of Costa Rica. A strip design was used, where the production of fresh and dry biomass, plant height, stem and leaf length, chlorophyll content, crude protein, and number of nodes per stem were quanti(ed; an analysis of variance was performed for each variable. 'e use of a planting distance of 70 cm with a harvest frequency of 70 auc, showed higher values for fresh biomass (p < 0,0001), dry biomass production (p < 0,0068), height (p < 0,0194) and stem length (p < 0,0093), compared to the other combinations. While a combination of a planting distance of 85 cm and a harvest frequency of 45 auc, presented higher values for chlorophyll content (p < 0,0284) and percentage of crude protein (p < 0,0134). At early cutting ages there was a higher chlorophyll and crude protein content, while at later ages there was higher biomass production. Due to productivity and protein content, Cuba OM-22 is an alternative for forage banks.

ABSTRACT This study aimed to identify the correlations between traits of the groups stem cutting, seedling, stem, and root of cassava. Length, diameter, and weight of stem cutting (Group 1) were measured at each growing season (July, August, September, and October). A total of 300 cuttings were collected after sprouting and planted at seasons of September 22, October 7 and 19, and November 25. Plant height at planting, number of leaves at planting, and number of leaves at 7 days after planting were measured. The number of leaves at transplanting and plant height at transplanting were determined after acclimation (Group 2). Seedling transplanting was carried out on November 9 and 24 and December 3 and 26, and the traits stem (Group 3) and root (Group 4) yield were measured at harvest. Associations between the groups stem cutting and seedling were established by stem cutting diameter and weight, and height and number of leaves at planting. Seedling traits had the greatest influence on the number of buds per stem and stem diameter. Main stem branching height and stem diameter can be used for selecting plants with an indication of the best quality and yield of root traits. cassava Length Group 1 July, July (July August October. .

Abstract The agronomic parameters of Tithonia diversifolia were evaluated by the effect of four cutting heights (AC) from the ground (AC1: 0 cm, AC2: 10 cm, AC3: 20 cm, AC4: 30 cm); with four replicates each, by 55 days. Shoots/tiller, leaves/shoot and leaves/tiller were higher (p<0.05) in AC1. However, the number of leaves/bush and shoots/bush were higher (p<0.05) in AC2, AC3 and AC4. The green forage weight (FV)/tiller was higher (p<0.05) in AC1; although, the weight of FV/mat was higher in AC2, AC3 and AC4, showing a higher (p<0.05) yield (kg/m2) in FV and dry matter for AC2, AC3 and AC4. The higher number of leaves/shoot (p<0.05) in AC2 than AC4 could improve the productivity of T. diversifolia, suggesting AC2 as adequate AC.

Los brotes/macollo, hojas/brote y hojas/macollo fueron mayores (p<0.05) en AC1. Sin embargo, el número de hojas/mata y brotes/mata fueron mayores (p<0.05) en AC2, AC3 y AC4. El peso de forraje verde (FV)/macollo fue mayor (p<0.05) en AC1; aunque el peso de FV/mata fue mayor en AC2, AC3 y AC4, mostrando un mayor (p<0.05) rendimiento (kg/m2) en FV y materia seca para AC2, AC3 y AC4. El mayor número de hojas/brote (p<0.05) en AC2 que AC4 podría mejorar la productividad de T. diversifolia, sugiriendo a AC2 como adecuada AC.

Abstract Measuring forage mass (FM) in the pasture, prior to grazing, is critical to determining the daily allocation of forage in pastoral animal production systems. FM is estimated by cutting forage in known areas, using allometric equations, or with the use of remote sensors (RS); however, the accuracy and practicality of the different methods for estimating FM is variable. The objective was to obtain predictive models using environmental and pasture management variables to predict FM. Regression models were fitted to estimate FM based on variables of pasture management (PM) or measurements obtained by RS, such as reflectance, air temperature, and rainfall. A mixed pasture grazed by beef cattle was studied for three years. With 80 % of data, models were built by ordinary least squares (OLS) or by machine learning (ML) algorithms. The remaining 20 % of the data was used to validate the models using the coefficient of determination and average bias between estimated and observed values. The base model of study was the relationship between pasture height before grazing and FM, this model was fitted using OLS; the r2 was 0.43. When models that included PM variables were fitted, the r2 was 0.45 for OLS and 0.63 for ML. When fitting models with PM and RS variables, the r2 was 0.71 for OLS and 0.96 for ML. ML-fitted model ensembles reduced the bias of FM estimates of the examined pasture. Overall, ML models better represented the relationship between pasture height before grazing and FM than OLS models, when fitted with pasture management variables and RS information. ML models can be used as a tool for daily decision-making in pastoral production systems.

Resumen Medir la masa de forraje (MF) en la pradera, antes del pastoreo, es fundamental para determinar la asignación diaria de forraje en sistemas pastoriles de producción animal. La MF se estima por corte de forraje en áreas conocidas, utilizando ecuaciones alométricas, o con el uso de sensores de percepción remota (PR); sin embargo, la exactitud y practicidad de los distintos métodos para estimar la MF, es variable. El objetivo fue obtener modelos predictivos usando variables ambientales y del manejo de la pradera para predecir la MF. Se ajustaron modelos de regresión para estimar la MF con base en variables del manejo de la pradera (MP) o mediciones obtenidas por PR, como reflectancia, temperatura del aire y lluvia. Por tres años se estudió una pradera mixta pastoreada con bovinos productores de carne. Con 80 % de datos se modeló por mínimos cuadrados ordinarios (OLS) o por algoritmos de aprendizaje automatizado (ML). El 20 % restante de los datos se utilizó para validar los modelos usando el coeficiente de determinación y el sesgo promedio entre valores estimados y observados. El modelo base de estudio fue la relación entre la altura de la pradera antes del pastoreo y la MF de este modelo se ajustó usando OLS; la r2 fue 0.43. Cuando se ajustaron modelos que incluyeron variables del MP, la r2 fue 0.45 para OLS y 0.63 para ML. Al ajustar modelos con variables de MP y PR, la r2 fue 0.71 para OLS y 0.96 para ML. Los ensambles de modelos ajustados con ML redujeron el sesgo de estimados de MF de la pradera examinada. En general, los modelos de ML representaron mejor la relación entre altura de la pradera antes del pastoreo y MF que los de modelos de OLS, al ajustarlos con variables de manejo de la pradera y con información de PR. Los modelos de ML pueden usarse como herramienta para la toma de decisiones diaria en sistemas productivos pastoriles.

ABSTRACT. French lavender (Lavandula dentata L.) is of great ornamental, medicinal, and aromatic interest. It is generally propagated vegetatively using stem cuttings. When using artificial lighting, a specific light composition can modify the entire plant phenology and is a factor that can be managed in controlled conditions. This study evaluated the rooting of stem cuttings and growth of lavender under four spectral LED lights. The LED lights used were: T0 (white LED, Roblan®), T1 (AP67 Milky, Valoya®), T2 (NS1, Valoya®), and T3 (AP673L Milky, Valoya®). The first phase evaluated the rooting of stem cuttings and initial development. The plants were then transferred to plastic pots to evaluate plant growth. In both rooting and growing phases, the plant morphological characteristics and water and light efficiencies were evaluated. Nutrient-uptake efficiencies were also evaluated after the growing phase. It was observed that cuttings rooted under the influence of T1 showed greater height. After the growing phase, plants under T3 showed better results in electricity use efficiency, water use efficiency, and nutrient-uptake efficiency and less nitrate leaching. They also presented more uniform growth with a compact canopy. Thus, T1 was better for the stem cuttings rooting phase, while T3 was better for growth and energy efficiency. ABSTRACT Lavandula L.

ABSTRACT Depending on the purpose of its cultivation, pigeon pea can be grown under different spacings and cuts, since it quickly resprouts. This study aimed to assess the pigeon pea growth, forage production and quality, considering two spacings and one cut. A field experiment using a completely randomized design, with three treatments [1.0 × 0.2 m spacing (between rows and plants, respectively), without cuts; 0.5 × 0.1 m, without cuts; and 0.5 × 0.1 m, with cut at 90 days after emergence (DAE)], was carried out. The spacings did not affect the plant height. The 0.5 × 0.1 m spacing showed an individual plant growth worse, but a forage yield (kg ha-1) higher than the 1.0 × 0.2 m treatment, from 120 to 180 DAE. The 0.5 × 0.1 m spacing was more advantageous than the 1.0 × 0.2 m, with the highest forage yield obtained by harvesting at 150 DAE. It is better to harvest the forage at 90 DAE and harvest it again at 180 DAE than maintaining a continuous plant growth and harvest it at 180 DAE. In each sampling date, there was no difference for stem and leaf crude protein and starch content as a function of the treatments. The forage harvested from 90 to 180 DAE showed similar crude protein and starch contents. So, for this period, the forage quality is not a limiting factor for establishing the harvest time. cultivation cuts resprouts design 10 1 0 [1. 02 2 0. between plants respectively, respectively , respectively) 05 5 01 9 DAE, (DAE)] out height worse kg ha1 ha ha-1 1. treatment 12 18 15 date contents So period time [1 (DAE) ha- [ (DAE

RESUMO Dependendo da finalidade, o guandu pode ser cultivado sob diferentes espaçamentos e cortes, pois rebrota rapidamente. Objetivou-se avaliar o crescimento, produção e qualidade de forragem de guandu, considerando-se dois espaçamentos e um corte. Um experimento de campo foi conduzido em delineamento inteiramente casualizado, com três tratamentos [espaçamento de 1,0 × 0,2 m (entre linhas e plantas, respectivamente), sem corte; 0,5 × 0,1 m, sem corte; e 0,5 × 0,1 m, com plantas cortadas aos 90 dias após a emergência (DAE)] e sete repetições. Os espaçamentos não influenciaram na altura das plantas. O espaçamento de 0,5 × 0,1 m apresentou pior crescimento individual das plantas, mas maior produtividade de forragem (kg ha-1) do que o espaçamento de 1,0 × 0,2 m, dos 120 aos 180 DAE. O espaçamento de 0,5 x 0,1 m foi mais vantajoso que o de 1,0 x 0,2 m, sendo a maior produtividade de forragem obtida na colheita aos 150 DAE. É melhor colher a forragem aos 90 DAE e colher novamente aos 180 DAE do que manter o crescimento contínuo das plantas e colher somente aos 180 DAE. Em cada época de amostragem, não houve diferença nos teores de proteína bruta e amido do caule e folha em função dos tratamentos. A forragem colhida dos 90 aos 180 DAE apresentou teores de proteína bruta e amido semelhantes. Assim, nesse período, a qualidade da forragem não é um fator limitante para definir o momento da colheita. finalidade cortes rapidamente Objetivouse Objetivou se considerandose considerando corte casualizado 10 1 0 1, 02 2 0, entre respectivamente, respectivamente , respectivamente) 05 5 01 9 (DAE) repetições kg ha1 ha ha-1 12 18 15 amostragem semelhantes Assim período (DAE ha-

Abstract The objective of this work was to evaluate the morphophysiological responses and cutting production of clones of Conilon coffee (Coffea canephora) cultivars in a super-dense clonal garden in the state of Espírito Santo, Brazil. The super-dense clonal garden was built in 2019 using 39 clones: 9, 9, 9, and 12 of cultivars Centenária ES8132, Diamante ES8112, ES8122 (Jequitibá), and Marilândia ES8143, respectively. The experiment was carried out in a randomized complete block design, with three replicates. Cutting production and the following morphophysiological traits were evaluated at 9 and 18 months after planting: chlorophyll index, normalized difference vegetation index, plant height, canopy height, canopy diameter, number of shoots, number of viable cuttings, number of leaves, fresh leaf mass, and plant fresh and dry matter mass. The super-dense clonal garden caused different morphophysiological responses among the studied clones. In general, clones C2, C5, C6, C8, D1, D8, D9, J8, M2, M9, M10, and M12 showed a higher mean cutting production, whereas C4, J1, J4, M4, and M5 were the most sensitive to the super-dense regime. Under these conditions, it is recommended to increase the proportion of matrix plants of the latter clones.

Resumo O objetivo deste trabalho foi avaliar as respostas morfofisiológicas e a produção de estacas de clones de cultivares de café conilon (Coffea canephora) em jardim clonal superadensado, no estado do Espírito Santo, Brasil. O jardim clonal superadensado foi implantado em 2019, com 39 clones: 9, 9, 9 e 12 das cultivares Centenária ES8132, Diamante ES8112, ES8122 (Jequitibá) e Marilândia ES8143, respectivamente. O experimento foi realizado em delineamento em blocos ao acaso, com três repetições. A produção de estacas e as seguintes características morfofisiológicas foram avaliadas aos 9 e 18 meses após o plantio: índice de clorofila, índice de vegetação por diferença normalizada, altura da planta, altura da copa, diâmetro da copa, número de brotações, número de estacas viáveis, número de folhas, massa fresca de folhas, e massa fresca e seca da planta. O jardim clonal superadensado promoveu diferentes respostas morfofisiológicas entre os clones estudados. Em geral, os clones C2, C5, C6, C8, D1, D8, D9, J8, M2, M9, M10 e M12 apresentaram maior produção média de estacas, enquanto C4, J1, J4, M4 e M5 foram os mais sensíveis ao regime superdenso. Nessas condições, recomenda-se aumentar a proporção de plantas matrizes destes clones.

Abstract The objective of this work was to select black oat genotypes using the MGIDI for simultaneous selection, comparing it with the Smith-Hazel index. The experiment was carried out in Frederico Westphalen/RS and Pato Branco/PR, in a randomized block design, with three replications, with 9 genotypes tested. Days from emergence to flowering and maturation; cutting and plant height; number of tillers; panicle length; tiller, plant, panicle, panicle seed mass, green and dry; and seed yield were obtained. MGIDI selected the genotypes UFSMFW 2-01 and UFSMFW 2-04 for Frederico Westphalen and UFSMFW 2-07 and UFSMFW 2-04 for Pato Branco, which varied compared to the Smith-Hazel index in both environments. MGIDI was efficient in selecting the best black oat genotypes, showing desirable selection gains for most traits.

ABSTRACT Seedling production is one of the most important stages of plant cultivation, with quality mainly depending on the substrate and plant material used. This study aimed to evaluate the production of Pereskia aculeata seedlings combining substrates and cutting diameters. The experimental design was completely randomized, in a 5 × 3 factorial arrangement, corresponding to five substrate combinations (commercial, kapok, palm, commercial + kapok and commercial + palm) and three cutting diameter ranges (0.5-3.0, 3.1-5.5 and 5.6-8.0 mm). The following parameters were evaluated: plant height, leaf length and width, number of shoots and leaves, root length, shoot and root fresh mass, shoot and root dry mass, total fresh and dry mass and Dickson quality index. There was a significant interaction effect between substrates and cutting diameters on the seedlings formed, except for number of shoots, leaf length and root dry mass. Seedlings of higher quality can be achieved with larger cutting diameters combined with commercial substrate. The palm and kapok substrates can be used alternatively when combined with larger cutting diameters. cultivation randomized arrangement commercial, (commercial 0.53.0, 0530 0.5 3.0, 0 (0.5-3.0 3.15.5 3155 3.1 5.5 1 3.1-5. 5.68.0 5680 5.6 8.0 6 8 5.6-8. mm. mm . mm) evaluated height width leaves index formed 53 0.53.0 053 05 0. 30 3.0 (0.5-3. 15 3.15. 315 31 3. 55 5. 3.1-5 68 5.68. 568 56 80 8. 5.6-8 0.53.

RESUMO A produção de mudas é uma das etapas mais importantes no cultivo de hortaliças, com qualidade dependendo principalmente do substrato e do material vegetal adotado. Objetivou-se avaliar a produção de mudas de Pereskia aculeata combinando substratos e diâmetros de estaca. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 5 × 3, com combinação de cinco substratos (comercial, samaúma, palheira, comercial + samaúma e comercial + palheira) e três faixas de diâmetro de estaca (0,5-3,0; 3,1-5,5; e 5,6-8,0 mm). Foram avaliados a altura, comprimento e largura das folhas, número de brotos e de folhas, comprimento da raiz, massa fresca da parte aérea e raízes, massa seca da parte aérea e raízes, massa fresca e seca total, bem como calculado o índice de qualidade de Dickson. Houve interação significativa entre os substratos e diâmetros de corte nas mudas formadas, exceto para número de brotos, comprimento de folha e massa seca de raiz. Mudas de maior qualidade podem ser obtidas a partir de estacas de maior diâmetro em combinação com substrato comercial. Os substratos de palheira e samaúma podem ser uma alternativa, quando combinados com estacas de maior diâmetro. hortaliças adotado Objetivouse Objetivou se casualizado 3 comercial, (comercial 0,53,0 0530 0,5 3,0 0 (0,5-3,0 3,15,5 3155 3,1 5,5 1 3,1-5,5 5,68,0 5680 5,6 8,0 6 8 5,6-8, mm. mm . mm) altura folhas raiz raízes total Dickson formadas alternativa 53 0,53, 053 05 0, 30 (0,5-3, 15 3,15, 315 31 55 5, 3,1-5, 68 5,68, 568 56 80 8, 5,6-8 0,53 (0,5-3 3,15 3,1-5 5,68 5,6- (0,5- 3,1- (0,5 (0, (0 (
