Dry Matter Partitioning and Yield of Different Varieties of Soybean (Glycine max (L.) Merrill) under Aberrant Climatic Conditions in Central India
Journal Title: International Journal of Plant & Soil Science - Year 2017, Vol 14, Issue 6
Abstract
Aim: To study the effect of sowing dates on dry matter partitioning and yields of soybean cultivars field experiment was carried out at Indian Institute of Soil Science, Bhopal. Materials and Methods: Ten varieties of soybean were raised in two sowing dates under rainfed conditions in black soil of central India. First sowing was done at optimum date (first week of July) and second 15 days after the first date. Results: Results showed that sowing at optimum date recorded significantly higher pre-flowering DMP (7.65 g plant-1), DMP at maturity (13.27 g plant-1), percent of post flowering DM partitioning into seed (46.45 %), pod dry weight (5.02 g plant-1), seed weight (2.67 g plant-1) and HI (34%) compared to second sowing. Among the varieties JS 8021 recorded significantly higher pre flowering DMP (8.34 g plant-1) followed by JS 9752 (7.7 g plant-1), DM at maturity by JS 9752 (12.73 g plant-1), pod weight (5.4 g plant-1) and seed weight (3.19 g plant-1) by JS 9560 followed by JS 9752 (4.1 g plant-1 and 2.15 g plant-1 respectively) and HI by JS 9560 (0.34). Conclusion: It can be concluded that the variety JS 9752 may be taken up to minimize the yield loss due to delay in sowing.
