Resumo: A pesquisa foi realizada com os ribeirinhos de Cuiabá e Várzea Grande, MT, com o objetivo de avaliar o perfil florístico com enfoque nas cultivares alimentares em quintais agroflorestais dessas regiões ribeirinhas. Verificou-se a predominância de oito espécies nos quintais agroflorestais: Mangifera indica, Annona squamosa, Carica papaya, Citrus latifolia, Citrus sinensis, Malphighia emarginata, Allium fistulosum e Anacardium occidentale.

Abstract: The research was carried out with the riverside people in Cuiabá and Várzea Grande, MT, to evaluate the floristic profile aiming at the food cultivars in agroforestry yards of these riverside regions. There was a predominance of eight species in agroforestry yards: Mangifera indica, Annona squamosa, Carica papaya, Citrus latifolia, Citrus sinensis, Malphighia emarginata, Allium fistulosum, and Anacardium occidentale.

Abstract This experiment assessed the effects of biosolids in the soil’s chemical and physical characteristics. Soil was mixed to a biosolid in a totally randomized design, within a 5× 4 factorial scheme: five doses of biosolid (0, 60, 120, 180, and 240 m3 ha-1) and four depths (0-0.10; 0.10-0.20; 0.20-0.30; 0.30-0.40 m). Soil was placed in 50 L-tubs imitating the soil profile. Doses of biosolid were added to the soil and samples were retrieved after 120 days. Biosolid tended towards acidification, with very low P and K rates. Nutrient leaching, such as Mg, increases microporosity and the reduction of soil macroporosity should be considered in high doses of biosolid.

RESUMO Determinar a relação existente entre os nutrientes e o crescimento das plantas implica em estudos e a aplicação de análise estatística capaz de explicar essas interações. Diante disso, estabeleceu-se experimento com doses de N, P2O5 e K2O e seus efeitos nas correlações entre crescimento e os nutrientes em mudas de Tectona grandis, a partir da correlação canônica. As mudas foram submetidas às doses de N = 0, 2,5, 5,0 e 7,5 kg m–3 com ureia, P2O5 = 0, 3,0, 6,0 e 12,0 kg m–3 com superfosfato simples e K2O = 0, 3,0, 6,0 e 12,0 kg m–3 com cloreto de potássio, em delineamento inteiramente casualizado. As correlações canônicas demonstraram que a biomassa foi a característica morfológica que mais se destacou em relação ao crescimento das mudas de T. grandis. Essa característica, assim como altura e diâmetro, foi favorecida pelas interações entre os macro e micronutrientes, que ocorreram no substrato após a adubação. N, Mn e Cu foram os nutrientes mais importantes para o incremento dessas características.

ABSTRACT The relationship between nutrients and plant growth requires in-depth studies and the application of statistical analysis capable of explaining these interactions. An experiment was prepared with N, P2O5 and K2O doses. Effects on the correlations between growth and nutrients in Tectona grandis seedlings were based on the canonical correlation analysis. Seedlings were submitted to doses of N = 0, 2.5, 5.0, 7.5 kg m–3 with urea, P2O5 = 0, 3.0, 6.0, 12.0 kg m–3 with common superphosphate, and K2O = 0, 3.0, 6.0, 12.0 kg m–3 with potassium chloride, in a completely randomized design. Canonical correlations showed that biomass was the most salient morphological characteristic in relation to the growth of T. grandis seedlings. Height and diameter were also underscored by interactions between macro- and micronutrients in the substrate, after fertilization. Results show that N, Mn and Cu were the most important nutrients for the increment of these characteristics.
