Abstract: The study was conducted at Kyungpook National University, College of Agriculture and Life Sciences experimental site, Daegu, South Korea from November 2017/2018. The research objectives were to investigate the response of different potassium applications rates on the growth and yield of mungbean in the greenhouse and outside and to find the best potassium application rate on mungbean for enhancing high production. The field experimental design was a randomized complete block design and each treatment had four replications. Mungbean (Vigna radiata L. ) was grown under five levels of potassium K1 (0g/pot), K2 (0.13g/pot), K3 (0.3g/pot), K4 (0.5g/pot) and K5 (0.63g/pot). The results showed that different potassium fertilizer applications have significantly affected the growth and yield of mungbean both inside and outside of the greenhouse. The application of K4 (0.5g/pot) produced the maximum seed yield (7.81g) inside the greenhouse and (8.16g) outside. The lowest yield (3.11g) and (3.82g) were observed at K1 (0g/pot) inside and outside of the greenhouse respectively. Total carbohydrates and total proteins content were significantly increased by increasing applications of potassium. It can be concluded that the application of K4 (0.5g/pot) have shown the best results and can be used to get the maximum growth and yield of mungbean both inside and outside of greenhouse conditions. The potassium application outside condition gave a significantly higher growth and seed yield than inside the greenhouse.
