Abstract: Field experiment was conducted to work out the effect of different residual sodium carbonate (RSC) waters, FYM and zinc fertilization on soil microbial biomass, nutrient uptake, sodicity tolerance and yield of Barley on loamy sand soil during rabi seasons of 2013-14 and 2014-15. The treatments were: Three levels of RSC waters (control, 5 and 10 mmol L-1), two levels of FYM (control and 15 t ha-1) in main plot and four levels of zinc (control, 15, 30 and 45 kg ZnSO4 ha-1) in sub-plot. Result revealed that under irrigation with high RSC (10 mmol L-1) of irrigation water the soil biological activity like microbial biomass C, N and P at different months, nutrient uptake viz., N, P, K, Ca, Mg, Zn, Ca/Mg ratios and yield of grain and straw of barley was decreased significantly, while, Na/K, Na+K/Ca and Na/Ca ratio of grain and straw increased significantly with increasing RSC in irrigation water. Application of 15 t FYM ha-1 showed significant increase in soil microbial biomass C, N and P at different months. The nutrient uptake (N, P, K, Ca, Mg and Zn), Ca/Mg ratio and yield of grain and straw of barley, increased significantly, while, Na/K, Na+K/Ca and Na/Ca ratio decreased significantly due to application of FYM @15 t ha-1 in grain and straw. The increasing level of Zn significantly increased the N, K, Zn, Ca, Mg uptake and yield of grain and straw of barley at harvest, while, Na/K, Na+K/Ca and Na/Ca ratios in grain and straw were decreased significantly.
