Mungbean variety M-1-A was grown before and after rice in the farmers' fields. Plants were either row planted or broadcasted using a plant population of 150,000, 200,000 and 250,000 plants per hectare. Maturity date of mungbean was slightly delayed when grown before rice due to availability of moisture. Day to flower for mungbean grown beforerice was 45 DAE (days after emergence). Plants grown after rice flowered at 36 DAE. Flowering period was 12 days for both seasons. Dry matter production and yield of mungbean grown before and after rice varied with plant population and moisture supply. As plant population increased, dry matter per unit area for crop grown after rice increased. However, we did not obtain a significant increase in dry matter as plant population increased for crop grown before rice. Growth rate for crop grown before rice was high due to soil moisture availability. Positive correlation between crop growth rate and leaf area per plant, leaf area index, plant height and number of flower were obtained. Yield of mungbean was higher when grown before rice crop. However, an increase in plant population caused lower yield epr plant due to competition. Higher percentage of pod set was the main contributor for higher yield in both experiments
