Abstract
Two mungbean varieties namely, Pag-asa 3 and Pag-asa 5 were studied in pure stands and two-way mixtures with 10, 25, 50, 75 and 90% of each variety at different planting rates of 10, 20, 30 and 40 seeds per linear meter, to determine the yield performance of genotype frequency and planting rate; to identify the yield components that are affected by various genotypic frequencies and plant populations, and to determine the extent of mutually favorable interaction between two interactions may be affected by populations density and/or by genotypic frequency. When average across all population densities, all mixtures yielded higher than the mean yield of Pag-asa 3 (the lower yielding genotype) in pure stand but lower than that of Pag-asa 5 (the higher yielding genotype) except the mixture having 25% Pag-asa 3 and 75% Pag-asa 5, which yielded 2.7% higher than the yield of Pag-asa 5. The best performing mixtures at lower planting rates were 50% Pag-asa 5 (at 10 seeds per linear meter). And 25% Pag-asa 3 and 75% Pag-asa 5 (at 20 seeds per linear meter). The best mixture at higher planting rates were 10% Pag-asa 3 and 90% Pag-asa 5 (at 30 seeds per linear meter), and 25% Pag-asa 3 and 75% Pag-asa 5 (at 40 seeds per linear meter). These mixtures yielded higher than the yielded of Pag-asa 5 in pure stand. The results of this study show a positive interaction for yielded between mixtures of Pag-asa 3 and Pag-asa 5.
