A pot culture experiment was conducted to study the effect of saline and saline-sodic soils on Rhizobium population and its influence on growth and yield of soybean during Kharif-2008, in the Department of Soil Science and Agricultural Chemistry at Mahatma Phule Krishi Vidyapeeth, Rahuri. The maximum rhizobial population and ischolar_main nodulation was observed in normal soil with low pH and lower salt concentration. The pH of this soil was observed to be favourable for the microbial growth. The soil rhizobial population was lower in saline soil than the normal soil due to increased pH and high salt concentration. A significant increase in yield was also observed by Bradyrhizobium seed inoculation in saline-sodic soils over the uninoculated treatment.

Abstract


A pot culture experiment was conducted to study the effect of saline and saline-sodic soils on Rhizobium population and its influence on growth and yield of soybean during Kharif-2008, in the Department of Soil Science and Agricultural Chemistry at Mahatma Phule Krishi Vidyapeeth, Rahuri. The maximum rhizobial population and ischolar_main nodulation was observed in normal soil with low pH and lower salt concentration. The pH of this soil was observed to be favourable for the microbial growth. The soil rhizobial population was lower in saline soil than the normal soil due to increased pH and high salt concentration. A significant increase in yield was also observed by Bradyrhizobium seed inoculation in saline-sodic soils over the uninoculated treatment.
