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– Convectional tillage with crop residue, T₂ – Convectional 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 growth attributes viz., plant height (7.71/7.91, 20.51/22.27, 37.61/40.16, 55.49/58.33 and 55.49/58.33 cm during 2019 and 2020 at 15, 30, 45, 60 and at harvest respectively), number of branches plant^-1 (1.84/2.04, 3.41/4.61, 4.52/5.49, 5.58/6.59 and 5.58/ 6.59 during 2019 and 2020 at 15, 30, 45, 60 and at harvest respectively), number of leaves plant^-1 (2.70/3.45, 8.58/10.04, 19.06/20.85, 14.72/16.60 and 8.22/ 10.45 during 2019 and 2020 at 15, 30, 45, 60 and at harvest respectively), leaf area plant^-1 (0.16/0.18, 1.51/2.02, 4.37/5.39, 8.72/10.19 and 3.86/5.32 dm² during 2019 and 2020 at 15, 30, 45, 60 and at harvest respectively) and dry matter plant^-1 (3.59/4.39/3.99, 11.56/14.25/12.90, 20.93/23.01/21.97 and 30.28/32.09/31.19 g during 2019 and 2020 at 30, 45, 60 and at harvest and on pooled mean basis respectively) recorded under conservation tillage practice minimum tillage with crop residue with 100% GRDF to kharif greengram.
