tailieunhanh - Effect of irrigation management and crop establishment methods on growth, yield, and economics of rice

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 . 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 . 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 ( cm), leaf area index (), number of panicles/m2 (), number of grains/panicle (), grain and straw yields (3722 and 5366 kg/ha), gross returns (84513 /ha),. | Effect of irrigation management and crop establishment methods on growth, yield, and economics of rice
