Effect of foliar application of phosphorus on yield, quality and economics of Bt cotton

Abstract

A field experiment was conducted during Kharif, 2023 in Northern dry zone of Karnataka to study the “Effect of foliar application of phosphorus on yield, quality and economics of Bt cotton” at Main Agricultural Research Station, UAS, Raichur. The Experiment was laid out in randomized complete block design with 11 treatments replicated thrice. The results revealed that, application of 75 percent recommended dose of phosphorus + foliar application of PSAP @ 0.5% each at 50, 75 and 100 DAS have shown significantly higher seed cotton yield and uptake whereas higher net returns and BC ratio were recorded with application of 75 percent recommended dose of phosphorus + foliar application of MKP @ 0.5% each at 50, 75 and 100 DAS. Whereas, control without phosphorous application has recorded lower yield, gross returns, net returns and BC ratio.
