Effect of Different Sowing Systems on Growth and Yield of Soybean Crop in Vertisol

摘要

An experiment was carried out during 2013-14, assess the effect of sowing systems on soil physical properties growth and yield of soybean crop. The soybean variety JS 97-52 was planted on clay loam soil under five different systems raised bed planter,broad bed, ridge and furrow, conventional seed cum fertilizer drill and zero till drill. It was found that soil moisture content was higher in raised bed planter as compared to other sowing systems. While bulk density and soil strength were relatively lower in ridge sowing plots as compared to seed cum fertilizer drill and zero till drill plots. The results of agronomic observations revealed that plant height, number of root/plant, depth of root, number of nodules/plant and total grain yield/ha were superior in raised bed planter, the second best was ridge and furrow planter, while seed zero till drill was found to be less effective. Soybean sown on ridges resulted in greater seed emergence 93.2%, plant height 72.3 cm, depth of root 15.66 cm, number of nodules/plant 99.23, which in turn caused greater grain yield 1673.89 kg/ha, thenext best was ridge and furrow planter, while zero till drill was not effective as other two systems.
