Abstract:
A Field experiment entitled “Effect of different plant spacings and nitrogen levels on growth and productivity of basmati rice (Oryza sativa L.) for Bathinda District of Punjab” was conducted during Kharif 2021 at Research Farm, Guru Kashi University, Talwandi Sabo, Bathinda (Punjab) to investigate the effect of plant spacing and nitrogen levels on yield and attributes yield of basmati rice. The experiment comprised of three plant spacing viz., 20 cm × 20 cm, 20 cm × 15 cm, and 15 cm × 15 cm and five nitrogen levels viz. 0, 75, 100 and 125 % RDN. The results revealed that wider spacing i.e. 20 cm × 20 cm significantly enhanced the plant growth parameters viz., plant height, dry matter, number of tillers per meter row length and yield attributing characters viz., number of effective tillers per meter row length, panicle length, number of grains per panicle and test weight than closer spacing i.e. 15 cm × 15 cm in basmati rice. Maximum grain yield (43.7 q/ha)was produced in wider spacing i.e. 20 cm × 20 cm which was statistically at par with spacing of 20 cm×15 cm and significantly higher than closer spacing i.e. 15c m×15 cm. Plant spacing of 20 cm × 20 cm recorded 2.58% and 8.17% higher grain yield than 20 cm × 15 cm and 15 cm × 15 cm, respectively. Nitrogen @ 125% RDN significantly increased the plant growth viz., plant height, dry matter, number of tillers per m row length and yield attributing characters viz., number of effective tillers per m row length, panicle length, number of grains/panicle and test weight than control (No fertilizer) and nitrogen @ 75% RDN in basmati rice. Nitrogen @125% RDN and nitrogen @ 100% RDN recorded statistically similar grain yield, straw yield and harvest index in basmati rice and were significantly higher than control and nitrogen @ 75% Recommended dose of nitrogen. Nitrogen level @ 125% RDN resulted in 20.8, 4.43 and 1.82% higher grain yield than control, nitrogen @ 75% Recommended of nitrogen and nitrogen level @ 100% Recommended dose of nitrogen.
