摘要

Introduction: Rice (Oryza sativa L.) is one of the most important staple foods for more than half ofthe world’s populationAim: To find out the most suitable nitrogen level for hybrid rice productivity in new alluvial zone ofwest Bengal.Study Design: The experiment was laid out in Factorial Randomized Block Design (FRBD) with 10treatment combinations and three replicates.Place and Duration of Study: Kharif seasons of 2018 and 2019 at Regional-Research Sub-Station(RRSS) Chakdaha of BCKV under new alluvial zone of West Bengal.Methods: Combinations having two hybrid rice varieties viz., V1 (PAN 2112 Gold), V2 (KRH-2) andfive nitrogen levels viz. N1 (0:60:60 N: P2O5: K2O Kg ha-1), N2 (50:60:60 N: P2O5: K2O Kg ha-1), N3(100:60:60 N: P2O5: K2O Kg ha-1), N4 (150:60:60 N: P2O5: K2O Kg ha-1), N5 (200:60:60 N: P2O5: K2OKg ha-1) Generally, yield contributing characters were studied at maturity of the crop. For yieldanalysis samples were taken from each plot and yield attributes were calculated.Results: Results revealed that almost all yield attributes gave significantly superior performance inthe variety PAN 2112 Gold with N4 level of fertilization. The maximum grain yield (5.10 t ha-1) wasrecorded in the variety V1 in combination with N4 level of nitrogen which was 6.69% more than KRH-2. Highest harvest index (50.86%) was noticed in same treatment combination.Conclusion: It may be concluded that PAN 2112 Gold with fertilizer dose N: P2O5: K2O 150:60:60Kg ha-1 can be recommended for South Bengal locations contributing to a yield of 5.10 t ha-1 as anAman crop.
