Abstract:

A field experiment was conducted in calcareous soil (medium in available K) in split-plot design with two rice varieties (Inbred and Hybrid) in main plot and six combinations of potassium management [control (unfertilized), NP (-K); NP+K (100 % basal); NP+K (50% basal + 50% tillering); NP+K(50% basal + 50% panicle) and NP+K (50% basal + 25% tillering + 25% panicle)] in sub-plot at experimental farm, RPCAU, Pusa, Samastipur, during kharif - 2017. The results revealed that the growth parameters ( plant height, panicle length, number of tillers m-2, number of panicles m-2), grain yield and test weight increased significantly with the application of potassium in three splits (50% basal + 25% tillering + 25% panicle) as compared to the treatment where potassium was applied only as basal dose (recommended practice).
