Abstract

Mungbean is a valuable crop, rich in protein, micronutrients, vitamins, anti-angiotensin agents, antioxidants, and anti-diabetic compounds. It is used in various forms, such as seeds for soup and green pods for salads. Additionally, mungbean is cultivated for green manuring, intercropping, nitrogen fixation, and crop rotation. It is predominantly grown in South Asia, West Africa, and Australia. However, the plant-environment interactions in other regions have not been thoroughly evaluated. In this study, we evaluated the growth and stability of previously untested mungbean germplasm in a new environment, specifically in the Free State Province of South Africa. The experiment was conducted during the summer season, which had predicted seasonal rainfall and optimal temperatures for mungbean germination, growth, and development, over two consecutive years. We measured various yield and yield-contributing traits, including grain yield per plant, plant height, number of branches, number of pods per plant, pod length, and number of seeds per pod, from three replicates. Data analysis using a T-test revealed no significant differences in plant growth and development between the two years. Despite these findings, the foreign mungbean germplasm requires further evaluation to determine its maximum yield potential and stability. Additionally, data on plant-pest and plant-disease interactions will be necessary to ensure sustained plant growth and to achieve the cultivation objectives.
