Abstract

                                Field experiment was conducted to study the effect of addition of organic manures on physical properties, yield of Sorghum and the residual effect on the succeeding Soybean with different tillage treatments for residue management at TNAU under Sorghum-Soybean cropping sequence. The results revealed that the addition of organic manures to the first crop of Sorghum improved the soil physical properties such as bulk density, hydraulic conductivity, capillary and non capillary porosity besides yield enhancement. The residual effect of organics on Soybean yield was also noticed. However, the level of irrigation had no effect on the physical properties studied.

Key words : Sorghum Soybean cropping system, organic manures, Bulk density, Hydraulic conductivity and Porosity
