Abstract:
An investigation was carried out at Post Graduate Institute Research Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra (India) on “Influence of conservation tillage practices and nutrient management on soil health and productivity of greengram– wheat cropping sequence” was conducted during 2019-20 and 2020-21. The soil of experimental field was sandy loam in texture. The experiment was laid out in split plot design during kharif season and split-split plot design during rabi season with three replications. The treatment consists of six main plot treatments of conservation tillage practices viz., T₁– Conventional tillage with crop residue, T₂ – Conventional tillage without crop residue, T₃ – Minimum tillage with crop residue, T₄ – Minimum tillage without crop residue, T₅ – Zero tillage with crop residue, T₆ – Zero tillage without crop residue and two sub plot treatments of nutrient management viz., F₁ – 75% GRDF, F₂ – 100% GRDF for kharif greengram during two consecutive years. The result revealed that mean higher yield attributes and yield viz., number of pods plant^-1 (17.73/19.60/18.66 during first year, second year and on pooled mean basis respectively), pods weight plant^-1 (14.26/16.28/15.27 g during first year, second year and on pooled mean basis respectively), number of seed pod^-1 (8.56/8.79/8.67 first year, second year and on pooled mean basis respectively), seed weight plant^-1 (9.40/10.26/9.83 g first year, second year and on pooled mean basis respectively), 100 seed weight (6.12/6.35/6.23 g first year, second year and on pooled mean basis respectively), seed yield (13.12/14.23/13.68 q ha^-1 first year, second year and on pooled mean basis respectively), straw yield (29.69/31.05/30.37 q ha^-1 first year, second year and on pooled mean basis respectively) and harvest index (30.51/31.29/30.90% first year, second year and on pooled mean basis respectively) recorded under conservation tillage practice minimum tillage with crop residue with 100% GRDF to kharif greengram.
