Abstract

The field experiment was conducted during 2005-2009 to study the effect of nutrient management modules on soil microbial population and fertility status of soil under system based cropping system. Population of soil bacteria, fungi and actinomycetes was favoured under the integrated management modules in both cropping system. Application of inorganic fertilizers coupled with organic biofertilizers to succeeding gram crop residues produced of previously crop augmented the available N and K of soil at the completion of 4^th cycle under soybean gram cropping system. The value of N, P and K status of soil were found significantly superior with the application of 50% RDF+FYM @ 5 t ha^-1 over organic or inorganic modules.

Abstract

The field experiment was conducted during 2006-2007 to study the effect of organic and inorganic on soil fertility and productivity of French bean in Vertisol. The highest grain yield, straw yield and growth parameters were observed where 150% RDF of NPK through chemical fertilizer including micronutrient and biofertilizers were applied. The higher level of NPK application that 150% RDF through chemical fertilizer recorded higher available N, P and K; while absence of chemical fertilizer that use of only vermicompost showed lower availability in soil. Application of FeSO₄, ZnSO₄ and vermicompost showed higher available Fe and Zn. It can be concluded that supply of higher quantity of NPK through chemical fertilizer was more efficient for harvesting maximum grain yield of French bean and improving quality parameters like protein content.
