Abstract
The study was carried out in the green house on a loess soil having day loam texture. The treatments comprised control, 100 kg N ha'', 75 kg P2 0, he, 20,000 kg farm yard manure (FYM) ha', 100 kg N +75 kg P20, and 100 kg N 75 kg P205 +20,000 kg (FYM) ha'. All the organic and inorganic constituents were thoroughly mixed with the soil in the pots at the time of sowing of maize crop. It was observed that NO3- N, available P and available K were significantly higher in the soil receiving nitrogen, phosphorous and FYM simultaneously. Particle density and bulk density of soil decreased by fertilizer application and maximum reduction of 6.7 and 4.6 %was observed in particle density and bulk density respectively in the soil treated with both organic and inorganic fertilizers. FYM application increased the saturation percentage (5-12.5%). Fertilizer application also caused reduction in pH(0.6%) and ECe ( 12-27%).
