Variety and Density Effects on Mungbean Eco-Physiology and Yield in Southeastern US

Jaekedah Christian, Tennessee State University


Mung bean (Vigna et al..) is a warm-season, C3 pulse crop of the legume family widely cultivated in Asian countries. As the demand for mung bean continues to increase in the United States, the ecophysiology, growth, and yield of mung bean varieties in the southeastern US need to be assessed. A field experiment was conducted at the Agricultural Research and Education Center of Tennessee State University to investigate the effects of four varieties (OK2000, Berken, TSU-1, AAMU-1) and three planting densities (5, 10, and 15 cm spacing) on the ecophysiology and yield of mung bean over 2 years. Results showed that for both years, the relative chlorophyll content, plant height, and harvest index significantly varied among the varieties, while plant dry biomass influenced the plant spacing. Pod dry biomass, pod number, crop yield, and harvest index were also influenced by variety in 2021 and plant dry biomass in 2022. Density only influenced transpiration relative chlorophyll content in 2021 and the number of pods per plant in 2022. OK2000 had more pods per plant, a higher harvest index, and a higher yield than other varieties. This study demonstrated that the mung bean variety OK2000 with a high yield would be ideal for commercial production in the southeastern US.
