Uso de biofertilizante na produtividade do milho

Abstract

Tem-se procurado incentivar o estudo de viabilidade do uso de sistemas integrados de produção de energia e alimentos para, da melhor forma possível, se utilizar os recursos específicos de cada agros sistema e se criar, sempre que possível, circuitos de realimentação entre diversas atividades. de modo a transformar resíduos em riquezas. Nesse contexto, desenvolveram-se estudos durante os anos de 2007 a 2011, em área experimental da Faculdade de Ciências Agrárias e Veterinárias da Universidade Estadual Paulista, em Jaboticabal-SP, Brasil.Utilizou-se de um latossol roxo com 12% de declividade e exposição Norte. Considerou-se como tratamentos a utilização de efluente de biodigestor incorporado ao solo em três doses diferentes, e como testemunha a adubação mineral convencional e sem adubação. Os principais aspectos analisados foram: densidade aparente do solo; Velocidade de infiltração da água no solo; desenvolvimento da área foliar, acumulação de matéria seca nas diferentes partes e produção de grãos da planta de milho. Da análise dos resultados e nas condições que se desenvolveu o estudo, concluiu-se que o efluente de biodigestor aplicado em anos consecutivos promove um melhor condicionamento do solo e um melhor desenvolvimento das plantas

The use of integrate systems has been stimulated to produce energy and food, so that specific resources of each agrosystem can be used in the best way, as well to create always as possible circuits of feedback between various activities so as to transform residues in wealth. so, a study using corn crop was carried out from 2007 to 2011, in the FCAV/UNESP Experimental Farm, in Jaboticabal City, State of São Paulo, Brazil. Red soil with 12% slope and north exposition was used. The treatments consisted of three levels of biodigestor biofertilizant incorporated into soil, conventional mineral fertilization (control 1) and without fertilization (control 2). To reach the objectives the following parameters were evaluated: soil apparent density, water infiltration speed into the soil, development of corn foliar area, dry matter accumulation and yield. Based on the results and the experimental conditions it was concluded that the biodigestor biofertilizant applied during successive years into the soil promoted better soil conditioning, as well as plant development
