Effect of Different Age of Seedlings and Nitrogen Levels on Growth and Yield of Rice (Oryza sativa L.)

Abstract

A field experiment was conducted during the kharif season (2021) at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad (U.P.). The soil of experimental plot was sandy loam in texture. The treatment consisted of T1­- 14 Days age seedlings + Nitrogen 100 kg/ha, T2- 14 Days age seedlings +Nitrogen 110 kg/ha, T3-14 days age seedlings + Nitrogen 120 kg/ha, T4­- 21 Days age seedlings + Nitrogen 100 kg/ha, T5- 21 Days age seedlings +Nitrogen 110 kg/ha, T6-21 days age seedlings + Nitrogen 120 kg/ha, T7­- 28 Days age seedlings + Nitrogen 100 kg/ha, T8- 28 Days age seedlings +Nitrogen 110 kg/ha, T9-28 days age seedlings + Nitrogen 120 kg/ha. The experiment was laid out in Randomized Block Design, with 9 treatments replicated thrice. Results revealed that maximum plant height(100.40 cm), number of tillers per hill (14.80), plant dry weight(53.06 g/plant), panicle length(32.30 cm), panicle per m2(320), no of panicle per hill (10.70), no of filled grains per panicle (165), test weight(26.40g), grain yield(4.16t/ha), stover yield(6.24t/ha), gross return (INR 1,11,904.00), net return (INR 78,275.400), B:C ratio (2.33) was recorded and significantly influenced with the treatment 21 days age seedlings +Nitrogen 120 kg/ha. Therefore, the treatment 21 days age seedlings + Nitrogen 120kg/ha was found more productive and cost effective.
