Foliar Response of Chemicals on Yield and Yield Attributing Characters of rice (Oryza sativa L.) Under Rain fed Condition

The present investigation entitled “Foliar Response of Chemicals on Yield and Yield Attributing Characters of rice (Oryza sativa L.) Under Rain fed Condition” was conducted during the Kharif season in 2016 at the Student Instructional Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad-224 229 (U.P.). Experiment was conducted in randomized block design with three replications and nine treatments on rice variety (Sahbhagidhan) under rainfed condition. Chemicals viz., foliar spray of 0.5 and 1.0%KCl, 1.0 and 2.0% MgSO4, 0.3 and 0.6% Boric acid and 0.25 and 0.5% Salicylic acid at two growth stages(15 DAT and milky stage) along with untreated control (distilled water spray). Yield and yield attributing characters viz., Number of panicle bearing tiller plant-1, Number of grains panicle-1, Number of sterile grains panicle-1, Grain yield (kg ha-1), Straw yield (kg ha-1) and Test weight (g)were improved by different chemical concentrations. On the basis of results obtained foliar application of various chemicals enhanced yield as compare to control under rain fed condition. The effects of 1.0 % MgSO4 were more pronounced fallowed by salicylic acid 0.25 and 0.5% as well as 1% KCl over other treatments.
