 ABSTRACT

A field experiment was carried out during kharif 2010 at IARI, New Delhi to study the performance of rice varieties under aerobic condition. The results revealed that among the varieties Pusa 834 recorded significantly higher grain yield (3.38 t/ha) and straw yield (5.32 t/ha) followed by PNR 162 (grain yield-3.08 t/ha; straw yield- 4.92 t/ha). Among the irrigation regimes, -10 kPa has given highest yield of (3.29 t/ha) followed by irrigation at -20 kPa (2.97 t/ha). Significantly higher gross return (39,399 /ha), net return (19,881 /ha) and benefit cost ratio (1.02) was observed in irrigation regime at -10 kPa followed by irrigation at -20 kPa (35,571 /ha and 16,953 /ha). Pusa 834 has given the highest net return (26,111 /ha) and benefit cost ratio (1.34) followed by PNR 162 (23,815 /ha and 1.22 respectively) at -10 kPa. The lowest net return (1682 /ha) and benefit cost ratio (0.10) was obtained in Jaldi Dhan 6 at -30 kPa soil water potential.

Keywords: Grain yield, Gross return, Net return and Benefit cost ratio.
