A field experiment was conducted to study the effect of benzyl aminopurine (BAP) on growth, yield and biochemical characteristicsof three summer mungbean cultivars, cv. Binamoog-5, BARI mung 6 and Binamoog-8 along with four treatments viz., H1-control (without BAP), H2-50 ppm BAP, H3-100 ppm BAP and H4-150 ppm BAPapplied at 15, 30, 45 and 60 days after sowing (DAS). Data were recorded on plant height, number of leaves plant-1, leaf area plant-1, dry root weight, root volume, number of root nodule, seed yield, chlorophyll, carotenoid and proline contents. Plant height, number of leaves plant-1, leaf area plant-1 and seed yield were statistically different among the cultivars and also significantly influenced by the application of different concentrations of BAP. The highest plant height (68.59 cm), number of leaves plant-1 (10.89), leaf area plant-1 (1677.8 cm2) and seed yield (1.69 t ha-1) were obtained by applying 100 ppm BAP. The interaction effect of cultivars and different concentrations of BAPwere statistically significant on plant height, number of leaves plant-1, leaf area plant-1 and seed yield. The highest plant height (71.88 cm), number of leaves plant-1 (12.46), leaf area plant-1 (1863.26 cm2) and seed yield (1.87 t ha-1) were obtained in Binamoog-8 by spraying 100 ppm BAP. Chlorophyll, carotenoid and proline contents were significantly influenced by the application of different concentrations of BAP. The study infers that BAP enhanced growth and yield of summer mungbean cv. Binamoog-8, which might be an alternative eco-friendly management practices.
