Abstract
A field experiment on study of response of maize to integrated application od potassium and potassium solubilizing bacteria on yield and yield attributes was carried out at College Farm, Agricultural College, Mahanandi, Acharya N.G. Ranga Agricultural University during rabi, 2022-2023. The experiment was laid out in randomized block design with seven treatments and three replications. The results revealed that maximum cob length, number of grains per cob, test weight, kernel yield, stover yield and higher economics were recorded by the application of KSB @ 5 kg ha-1 as soil application and 100 % recommended dose of K2O (T7) which was on par with the KSB + 75 % recommended dose of K2O (T6) and recommended dose of N, P, K @ 260:80:80 kg ha-1 (T2). Harvest index does not exhibit any significant variations across different treatments tried during the study.
