Abstract:
An investigation was carried out at Post Graduate Institute Research Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra (India) on “Conservation agriculture for improving crop productivity and water use efficiency in soybean–wheat cropping system under deficit irrigation” during 2017 and 2018. The soil of experimental field was sandy loam in texture. The experiment was laid out in split plot design with of four main plot treatments of irrigation scheduling on the basis of depletion of available soil moisture (DASM)] viz., I₁ – 40% of DASM, I₂ – 50% of DASM, I₃ – 60% of DASM, I₄ – As per critical growth stages (CGS) and two sub plot treatments of tillage practices viz., T₁ – Zero tillage, T₂ – Conventional tillage during two consecutive years. The result revealed that mean higher growth attributes viz., plant height (20.86/22.57, 52.69/54.28, 55.06/56.08 and 55.32/56.29 cm during 2017 and 2018 at 30, 60, 90 DAS and at harvest respectively), number of branches plant^-1 (2.73/2.99, 6.49/6.90, 6.85/7.30 during 2017 and 2018 at 30, 60 and 90 DAS respectively), number of leaves plant^-1 (7.37/7.77, 22.65/23.79 and 7.58/7.09 during 2017 and 2018 at 30, 60 and 90 DAS respectively), leaf area plant^-1 (3.41/4.40, 32.08/33.63 and 3.75/4.49 dm² during 2017 and 2018 at 30, 60 and 90 DAS respectively) and dry matter plant^-1 (5.37/6.56, 32.34/33.33, 34.91/36.04 and 35.43/36.95 g during 2017 and 2018 at 30, 60, 90 DAS and at harvest respectively) recorded under scheduling of irrigation at 40 per cent of DASM with conventional tillage practice to kharif soybean (Glycine max L.).
