Impact of phosphorus levels on barley (Hordeum vulgare L.) crop productivity and nutrition under Satna conditions

Abstract

The field experiment was conducted at A.K.S. University, Satna, during the winter season of 2022-23. The soil was silty clay-loam with a pH of 7.35, electrical conductivity of 0.22 dS/m, and organic carbon of 0.48%. 12 organic treatments were applied to the JB-1 variety of barley, with a uniform dose of 60 kg N and 30 kg K2O/ha. The crop was grown according to the recommended practices. The results showed that applying phosphorus up to 60 kg/ha was beneficial for maximum yield, seed quality, and NPK uptake from the soil. The seed yield of barley was up to 35.38 q/ha, and the total N, P, and K uptake was 103.4 kg N, 17.09 kg P, and 137.0 kg K/ha, respectively. The addition of phosphorus up to 60 kg/ha improved residual soil properties like E.C., O.C., and available NPK/ha after barley harvest.
