Abstract: An field experiment was carried out during the rabi season of 2012-13 to study the effect of nitrogen levels on productivity and profitability of wheat (Triticum aestivum L.) under sodic Vertisols at Salinity Research Farm, Barwaha, Indore (MP). Six levels of nitrogen viz., 0, 30, 60, 90, 120 and 150 kg ha-1 was laid out in randomized block design with four replications. The results showed that increasing levels of nitrogen significantly increased the yields, economics, N content, uptake, protein content and available N in soil when compared to control. Among the different levels of nitrogen, application of 150 kg N ha-1 produced highest grain yield (35.89 q ha-1), straw yield (48.85 q ha-1), N content (2.02% in grain and 0.40% in straw), N uptake (72.49 by grain and 19.60 by straw kg ha-1) and protein content (12.63%). Significantly higher gross return (Rs. 64896 ha-1), net returns (Rs. 40515 ha-1), B: C ratio (1.66) and available N in soil (173.10 kg ha-1) were recorded in 150 kg N ha-1 over control. The highest N use efficiency (10.94 kg grain kg-1 N) and lowest recovery of N (37.41%) was noted with highest levels of nitrogen i.e. 150 kg ha-1. Different levels of nitrogen did not influence the pH, ESP, EC and organic carbon status of the soil.
