Impact of Integrated Nutrient Management on Chemistry of Native Zinc in Alluvial soil under Rice Wheat system

Abstract

Integrated nutrient management aims for proficient and careful use of all the major sources of plant and soil nutrients in an integrated manner. The present study was carried out at Bihar Agricultural College farm Sabour entitled Impact of Integrated Nutrient Management on Chemistry of Native Zinc in Alluvial soil under Rice-Wheat system under IFS scheme started from 1984 comprising four replication and twelve treatment permutations. The treatment included three organic sources viz., FYM, wheat straw (WS) and green manuring (GM) with sesbania aculeate replacing 25 % and 50 % of the optimum N during kharif season, treatment replacing 50 % N through organic manure were given 100 % RDF in wheat while those receiving 25 % N replacement in rice got only 75 % RDF in wheat. Thus it was making six INM treatment permutations, which were assessed against 100 % RDF along with unfertilized absolute control. newline
