Abstract

Field experiments were carried out at Fertilizer Research Station, Uttaripura, Kanpur on wheat variety PBW-550 in rabi and maize variety Azad Uttam in zaid both under C. S. Azad University of Agriculture & Technology, Kanpur, Uttar Pradesh during 2012–13 and 2013–14 to evaluate the response ofadditional application of foliar grade SOP (K-leafTM) on yield and quality of wheat and maize. Results of the experiments revealed that use of foliar grade SOP (K-leafTM) significantly increased grain and stover yield of both the crops. Two sprays of SOP with recommended NPK increased yield of grain and straw over one spray of SOP but could not reach up to the level of significance. Reduction in the dose of potassium by 25% with two foliar sprays found better than full dose of potassium with one foliar spray of SOP.
