| The objective of this research was to investigate the effect of different rates of cattle manure with or without mungbean crop residues incorporated into the soil after harvesting, on growth and yield of transplanted rice as well as economic return of mungbean as pre-rice crop. An experiment was conducted in a farmer’s field in Muang Yai Village, Khon Kaen Province, Thailand, in 2011. A split-plot arrangement of treatments in a RCBD was used, with pre-rice mungbean or fallow with weeds incorporated into the soil in main plots, and cattle manure at four rates (0; 3125; 6250; 9375 kg/ha) as subplots. Incorporation of mungbean residue into the soil provided 3.2 t of dry matter per ha containing 50.2 kg N, 9.8 kg P and 166.2 kg K per ha. Incorporation of weeds... |
