Effect of Rhizobium Inoculation on Pea Irrigated with Waters of Different Residual Sodium Carbonate Levels

Two field experiments were conducted on alkaline loamy sand soils to study the effect of Rhizobium inoculations (with and without Mo under pelleting and non-pelleting conditions) on pea, irrigated with waters of different residual sodium carbonate (RSC) levels (3,6 and 9 m.e./l). Rhizobium inoculation (non-pelleted) proved to be the best of all the treatments for pod and straw yields in both the years of study and also increased the content of total N in the soil significantly. The ECe, hydraulic conductivity, and total N in the soil and pod and straw yield decreased and pH and ESP values of soils increased with increasing levels of RSC in water in both the years.
