tailieunhanh - Effect of tillage, crop residues and nitrogen management practices on growth performance and soil microbial parameters in wheat

A field experiment was conducted at Indian Agricultural Research Institute, New Delhi during rabi seasons of 2014-15 and 2015-16 to assess the effect of tillage, crop residues and nitrogen management on growth performance and soil microbial parameters in wheat under soybean-wheat cropping system. The experiment was laid out in split plot design with 4 tillage and residue management practices viz., Zero tillage without residue (ZT- R), zero tillage with soybean residue (ZT+SR), zero tillage with soybean residue and residual effect of preceding wheat residue (ZT+SWR) and conventional tillage without residue (CT- R) in main plots and 4 nitrogen management practices viz., 100% recommended dose of nitrogen (RDN) as basal (N1), 125% RDN as basal (N2), 100% basal + 25% top dressing (N3) and 75 % basal + 25% top dressing (N4) in sub plots. The results revealed that the growth parameters of wheat and soil microbial activity were significantly improved with zero tillage & residue retention. | Effect of tillage, crop residues and nitrogen management practices on growth performance and soil microbial parameters in wheat
