摘要

A field experiment was conducted on a Vertisol at Main Agricultural Research Station, University of Agricultural Sciences. Dharwad during Kharif season of 2003-04 with a view to study the effect of integrated nitrogen management on yield and uptake of nutrients by maize. The treatments include supply of nitrogen through inorganics with distillery yeast sludge (DYS), farm yard manure (FYM) and pressmud (PM) which contain 1.45%. 0.58%. and 1.12% of nitrogen, respectively. Calculated quantity of nitrogen was applied to all eleven treatments with P and K as common application. The highest N (285 kg/ha) uptake was recorded in the treatment receiving 100% Recommended Dose of Nitrogen (RDN) through fertilizer. Significantly higher available nitrogen (286 kg/ha) was recorded in the treatment with 100% RDN through DYS at the harvest of crop. Significantly higher available P (35.7 kg/ha) was recorded in the treatment receiving 100% RDN through FYM, whereas K availability did not show marked differences among the treatments at harvest. The high uptake values resulted in high maize yield.
