Aim: To study the effect of rice hybrids to different nutrient management practices to find out the most suitable nutrient management and variety for hybrid rice in new alluvial zone of west Bengal.

Study Design: The experiment was laid out in Factorial Randomized Block Design (FRBD) with 20 treatment combinations with three replicates.

Place and Duration of Study: Rabi seasons of 2011-12 and 2012-13 at Regional-Research Sub-Station (RRSS) Chakdaha of BCKV under new alluvial zone of West Bengal.

Methods: Combinations having with five hybrid rice varieties viz., V1 (Winner), V2 (Champion) V3 (Raja), V4 (Karishma) V5 (KRH-2), and four nitrogen levels viz. N1 (150:75:75 N: P2O5: K2O Kg/ha), N2 (75%N of N1+ full dose of P2O5 & K2O as recommended in N1+ 25% N through FYM), N3 (50%N of N1+ full dose of P2O5 & K2O as recommended in N1+ 50% N through FYM), N4 (120:60:60 N: P2O5: K2O Kg/ha) Generally yield contributing characters were studied at maturity of the crop. For yield analysis samples were taken from each plot and yield attributes were calculated.

Results: Experimental results revealed that almost all the growth parameters and yield attributes gave significantly superior performance in the variety Champion with N1 level of fertilization. The maximum grain yield (7.49 t ha-1) was recorded in the variety V2 in combination with N1 level of nitrogen. Highest harvest index (52.23%) was noticed in same treatment combination.

Conclusion: It may be concluded that Champion can be recommended for South Bengal locations with N1 (i.e.150:75:75 N: P2O5: K2O Kg ha-1) nutrient level for maximum grain yield.
