Produção e qualidade fisiológica de sementes de feijão comum com aplicação de inoculante, adubação orgânica e mineral

Abstract

The common bean or harvesting of the cassava bean (Phaseolus vulgaris L.) is grown throughout the country and in the Northeast region contributes to the income of small farmers that by not providing the resources to invest in the production, cultivation has shown low yield. As a result, this research aimed to analyze the growth, development, production performance and physiological quality of seeds of commons bean plants cultivated with the combination of organic compost, biofertilizer and inoculants, compared with mineral fertilization. The first experiment was conducted under field conditions at the Universidade Federal Rural of Pernambuco, Unidade Acadêmica of Garanhuns (UFRPE/UAG) in Garanhuns-PE city, in the months from April to July 2013. The experimental design was a randomized block design consisting of nine treatments and three replications: T1 – control; T2 - organic compost; T3 – biofertilizers; T4 - inoculant; T5 - organic compost + inoculant T6 – biofertilizer + inoculants; T7 - organic compost + biofertilizer; T8 - organic compost + biofertilizer + inoculant; T9 - mineral fertilization. Variables of growth and agronomic traits in common bean plants were evaluated. A second experiment was conducted at the Laboratory of Seed Analysis UFRPE/UAG with seeds from planting in the field where analyzed the physiological quality measured by the germination and vigor tests. The average number of leaves was greater in plants referring to T7, T5, T9, T4 and T8 treatments. The green biomass at harvest was statistically higher in plants from T2 and T8 treatments. As for seed quality, treatments with organic fertilization and inoculation (T3, T4, T5, T6 and T7) were statistically equal treatment with mineral fertilizer (T9) for the variables of germination and vigor. The average length of root and shoot, and dry mass of roots and shoots of seedlings were influenced by fertilization with isolated biofertilizers (T3) and associated organic compost (T7). The production of beans to obtain grains and seeds can be realized with a combination of organic compost and biofertilizer.
