Abstract:

A field experiment was conducted during rainy (kharif) season of 2017 at crop research centre, Pusa, Bihar in split plot design. The treatments consisted of three irrigation management i.e. I1-Continuous submergence throughout crop growth, I2-Saturation maintenance upto PI and (5±2cm) after PI and I3- Alternate wetting and drying (5 cm irrigation at 3 DADPW) upto PI and (5±2cm) after PI in main plot and four methods of establishment i.e. E1- Normal transplanting, E2- Direct wet seeding on puddled soil, E3- Direct dry seeding and E4- Broadcasting on un-puddled soil in sub plots. The results of experiments showed that growth and yield attributes like plant height (117.71 cm), leaf area index (4.26), number of panicles/m2 (209.61), number of grains/panicle (88.04), grain and straw yields (3722 and 5366 kg/ha), gross returns (84513 /ha), net returns (41435 /ha) and B: C (0.98) ratio were not influenced by irrigation management but water use efficiency (37.90 kg/ha-cm) was found to be maximum with I3 and was significantly superior to I1, which was statistically at par with I2.With regard to crop establishment methods plant height (127.81 cm), leaf area index (4.64), panicles/m2 (219.12), number of grains/panicle (91.44), grain yield (4053 kg/ha), straw yield (5826 kg/ha), WUE (44.50 kg/ha-cm), gross returns (91955 /ha) and net returns(47190 /ha) were recorded maximum with E1 treatment of crop establishment methods which was significantly superior to E2, E3 and E4 except, number of panicles /m2 were statistically at par with E2 treatment and E3 while straw yield was statistically at par with E2 treatment. B: C ratio (1.06) was not influenced significantly due to different crop establishment methods.
