The researchers studied how different planting dates and spacing affected the growth and yield of rice bean fodder. They planted rice bean at different dates and row spacings in a field trial over three years. Planting on May 26th resulted in higher green fodder yield and plant height compared to later dates. The best row spacing was 35 cm, which led to higher growth and yield attributes. Overall, planting on May 26th with a row spacing of 35 cm gave the highest green fodder yield.
