São apresentados os resultados de ensaio de cultivares de alho, de curto e médio ciclos, escolhidos entre os mais promissores nos últimos anos, em Campinas. O trabalho visou verificar quais as melhores variedades, sob os aspectos de produtividade, precocidade e qualidade do produto. Os cultivares de ciclo médio (155 a 171 dias do plantio à colheita) superaram os de ciclo curto (128 a 141 dias), quanto à produção e tamanho dos bulbos. Dentre aqueles, destacaram-se: Cateto Ponte Seca 1-2102, Amarante 1-3935 e Lavínia (1-1632 e 1-3208), com produções acima de 1000 g por metro quadrado. Entre os alhos de ciclo curto, mereceu destaque o Cajuru 1-2315, com produção média de 662 g por metro quadrado. Quanto à qualidade do produto, quase todos se apresentaram com 100% dos bulbos perfeitos, exceção feita quanto ao Cateto Roxo 1-99 e Sergipe 1-3820, que apresentaram alguns bulbos imperfeitos (4,0% e 3,1% respectivamente).

A comparison of the production of early and median cycle garlic (Allium sativum L.) varieties was made at Centro Experimental de Campinas, SP. Median cycle cultivars (155 to 171 days from planting to harvesting) gave higher total yield and produced higher size bulbs than early ones (128 to 141 days). The best results were obtained with the cultivars Cateto Ponte Seca I-2102; Amarante I-3935; Lavínia I-1632 and Lavínia I-3208, which produced more than 1 kg/m². Among the early cultivars the more productive was Cajuru I-2315 with 0,6 kg/m². With regard to quality almost all of them gave 100% of perfect bulbs, except Cateto Roxo I-99 and Sergipe I-3820 which gave 4% and 3% of imperfect bulbs, respectively.

A competition trial, among nine strawberry (Fragariasp.) varieties and hybrids, was conducted at Monte Alegre Experimental Station, during the year of 1968. "Dr. Morère", also known as "Comum", formerly the most cultivated variety in the State of São Paulo, was included as standard. The planting was made in April, and the comparison was based on the total yield of fruits, from June to December. Partial productions of the periods June-July and November-December were also considered. It is noteworthy to mention that under São Paulo State market conditions, strawberry get higher prices in June-July period, because harvest is in the beginning and also the fruits are bigger. The obtained data indicated: a) If total yield from June to December was considered, the varieties Monte Alegre IAC-3113, Mantiqueira IAC-3976, Camanducaia IAC-3530 and Hybrid IAC-4110 produced significantly more than other varieties (Hybrid IAC-4109. Campinas IAC-2712, Hybrid IAC-2529, Hybrid IAC-3715 and Dr. Morère I-699); b) Considering the production on the period June-July, Monte Alegre IAC-3113 and Campinas IAC-2712 had the best performance; c) The partial production of the period November-December of the varieties Monte Alegre IAC-3113, Hybrid IAC-4110 and Hybrid IAC-2529 surpassed significantly that of the remaining varieties. Concerning commercial characteristics of the fruit such as size, taste, color and firmness, the varieties M. Alegre IAC-3113, Campinas IAC-2712 and Mantiqueira IAC-3976 exceeded that of the other varieties.

In this paper results of a trial of sweet pepper varieties are presented. The authors had in mind to study, besides productivity and quality, the resistance of the varieties to virus diseases, a factor which behinders and limits production of this crop under our conditions. Variety Agronômico-8 L 17, created in the Seção de Virologia of the Instituto Agronômico, and which produces fruits of conical-elongated shape, for the trade, outdid by far the others in productivity and in resistance to diseases. The following varieties reached the second place in productivity: Moura, Porto Rico Wonder, Casca Grossa and Yolo Wonder, producing different types of fruits. Less productive were the varieties Amarelo, Mogi das Cruzes, World Beater and Yolo Wonder, which presented more severe symptoms of diseases.

São apresentados os resultados de um ensaio de variedades de alface de cabeça. A variedade "Great Lakes'", do tipo de cabeça com fôlhas crêspas e verdes, mostrou-se mais produtiva e de melhor fechamento das cabeças. As variedades de fôlhas lisas situaram-se em segundo plano. Destas destacaram-se: "Shimabukuro", "Piracicaba" e "Gigante". As variedades menos produtivas foram "Maravilla de Ias Cuatro Estaciones" e "White Boston".

The authors present the results of a trial of lettuce varieties, nearly all of them belonging to the butter-head type. In addition to productivity and quality of product, the trial was performed with a view to verify the behavior of the varieties under high-temperature conditions prevailing from September to November, this being the end of the period of cultivating, acceptable in conditions as of the Paulista Plateau. The variety "Great Lakes", of the crisp-head type, excelled the others in productivity and formation of heads. The following varieties placed themselves second in order: "Shimabukuro", "Piracicaba", "Gigante", "Bautzener Dauerkopf" and "La Chaume", all of them of the butter-head type. The less productive varieties, also of the same type as the before mentioned, were: "Maravilla de las Cuatro Estaciones" and "White Boston", the former presents, however, the external leaves consistent and of brownish tint, this causing depreciation of its commercial value. Of all varieties, the "White Boston'' is the most tender one and is mostly given preference by the Paulista consumer.

In this paper the results obtained in 1966 at the Experimental Station of Monte Alegre do Sul are presented about strawberry variety trials. In all of them, variety «Dr. Morère», also known as «Comum», formerly the most cultivated in the State of São Paulo, was used as check plant. Nine varieties were studied. The total yield of June to December and also the partial one of June-July was studied, when the prices of strawberry are the highest, because harvest is beginning and also because fruits are bigger. The statistical analysis of data obtained showed the following results: a) concerning the total yield, variety Monte Alegre IAC-3113 without differing from varieties Camanducaia IAC-3530, Hybrid IAC-3432 and Hybrid IAC-2748, was superior to all the others (Campinas IAC-2712, Hybrid IAC-2529, Hybrid IAC-2747, Hybrid IAC-3592 and Dr. Morère I-699) to the level of 5%; b) considering the partial production, variety Monte Alegre IAC-3113 was superior to all the others to the level of 1% and variety Campinas IAC-2712, without differing from variety Monte Alegre IAC-3113, was superior to all the others to the level of 1%. Among the varieties studied the following have shown the best qualities: Monte Alegre IAC-3113, Campinas IAC-2712 and Camanducaia IAC-3530.

Visando eliminar as práticas convencionais de cultivo, nas lavouras de feijão-vagem (Phaseolus vulgarisL.), fêz-se uso, no combate às ervas daninhas, dos herbicidas EPTC, cloroxuron, trifluralin e DNBP. Quanto à produção total de vagens, não houve diferença significativa entre os diversos tratamentos. Todos os herbicidas experimentados revelaram eficácia no combate às ervas daninhas, sendo que o cloroxuron e o DNBP tiveram ação mais duradoura. O herbicida cloroxuron revelou-se fitotóxico para essa cultura, causando clorose pronunciada e consequent? morte de muitas plantas.

Four herbicides were tested ot control weeds in snap bean (Phascolus vulgarisL.) cultures, in pre-emergent conditions. EPTC and Irifluralin were incorporated before, whereas cloroxuron and DNBP after planting, but without incorporation iu the soil. A plot was cultivated by usual practices as check. Under the conditions of this experiment, there was no appreciable increase in the bean yield, but all the herbicides tested were efficacious in controlling the weeds. Those applied after planting showed better residual effects. Some toxicity of cloroxuron on snap beans was noted.

São apresentados os resultados de ensaio de variedades de alface pertencentes a diferentes tipos. Além da produtividade e qualidade do produto, o trabalho visou verificar o comportamento das variedades nas condições de temperaturas elevadas reinantes em agôsto-outubro, fim do período cultural recomendável nas condições do planalto paulista. A variedade "Great Lakes" superou enormemente as demais em produtividade e tipo das cabeças. A "Maravilla de las Cuatro Estaciones", a segunda colocada, revelou grande tolerância ao calor.

Results are presented hereunder concerning a trial installed in Campinas, in which no less than 8 varieties of lettuce (Lactuca sativa L.), belonging to different types, were tried. The main purpose of the trial was to verify which were the best varieties considering productivity and quality. An attempt was made to determine equally the behavior of the varieties in regard to temperatures existing in the period, in plantings carried out in August-October, this being the limit recommended for the conditions of the S. Paulo plateau. In this period the mean monthly temperatures of the air were 19.2°C, 22.6°C and 21.2ºC, for the months of August, September and October, respectively. From the results obtained it can be seen that variety Great Lakes-118 1-2912, belonging to the Crisp-head type, outdid all of the others in yield, size of plants and formation of heads. The Maravilla de Las Cuatro Estaciones I-2866 ranked second in yield, revealing that it stood warm weather fairly well, as it proved with the formation of good heads. This variety belongs to the Butter-head type, however with the external leaves consistent and of brownish tint. The varieties of Leaf and of the Cos or Romaine types, as B. S. Simpson 1-2391 and Romana Branca 1-2038, were excelled by the foregoing in yield and quality. The same was observed with the Gigante I-1797 and Piracicaba I-2575 varieties, which belong to the Butter-head type. The least productive ones were White Boston 1-2896 and Shimabukuro 1-2673, also belonging to the Butter-head type. The White Boston is the tenderest and most delicate of them all and of the most commercial demand of the S. Paulo market as well.
