Abstract

Abstract : Bed planting method for rice production systems is very new and research on it is still at an introductory phase. A field experiment was conducted to determine the effect of different agronomic aspects of bed planting on the growth and yield of transplanted aman rice (both irrigated and rain fed). This study also evaluates the water and fertilizer application efficiency of rice cropping system under bed planting method. Results showed that the bed planting method increased grain yield of rice up to 16% than the conventional method. Bed planting also increased the number of panicle m −2, number of grains panicle −1, and 1000-grain weight of rice than conventional method. Sterility percentage and weed infestation were lower in bed planting than conventional method. About 42% of the irrigation water and time for application could be saved through bed planting in transplanted aman rice cropping system. Water use efficiency and crop productivity for grain production were higher in bed planting over conventional method. This study concluded that bed planting method is a new approach for optimum fertilizer and water use efficiency as well as higher yield compared to conventional flat method.
