Abstract:

A long term field experiment was conducted during rabi 1988-89 at Rajendra Agricultural University, Pusa, Samastipurin split plot design with three replications. The treatment comprised of four levels of inorganic fertilizers in main plot and four levels of organic manure in sub-plot. Soil samples were drawn 15 days before transplanting and harvesting of rice. Under both the situation (15 days before transplanting and harvesting) integrated management of organics and chemical fertilizers were found to increase the urease enzymatic activity at 15 days before harvesting of rice. The maximum value of 114.5 mg of urea hydrolysed kg-1 soil ha-1 was recorded at 150 per cent NPK + compost + crop residue treatment whereas under 15 days before transplanting, the same treatment resulted 177.6 mg of urea hydrolysed kg-1 soil ha-1 indicating more urease activities at 15 days before transplanting. The effectiveness of the organic treatment on urease activity was found in the order: compost +crop residue>compost>crop residue> no manure. NPK 100 per cent with compost and crop residue was found most effective in increasing the urease activity of soil.
