tailieunhanh - Effect of zero tillage practices and nutritional levels on microbes, enzymatic activities in soil and productivity of pigeonpea under rainfed situations

A field experiment was conducted at KVK, Kalburgi, on black soils. The zero tillage practices were followed since 3 years in five main plots and different reduced nutrient levels were imposed as subplots, by following split plot design. Every year same crop pigeonpea genotype TS-3R was grown. The prophylactic measures were undertaken against pests and diseases. Biological observations were analysed at 50 per cent flowering. Results of experiment shows that higher seed yield, stalk yield, SPAD values and sustainable yield index were observed in zero till-raised bed with residues retention along with application of 100 per cent recommended dose of inorganic fertilizer compared to other combinations. | Effect of zero tillage practices and nutritional levels on microbes, enzymatic activities in soil and productivity of pigeonpea under rainfed situations
