Effect of salinity stress on the growth and yield of mungbean (Vigna radiata (L.) R. Wilczek) treated with mangosteen pericarp extract

Salinity stress is one of the environmental factors that limit crop production. The objective was to find out the effect of salinity stress on the growth and yield of mungbean (Vigna radiata (L.) R. Wilczek) treated with mangosteen pericarp extract. A randomised block design arranged in factorial pattern with two factors and three replications was used in the experiment. Salinity stress consisted of three levels, namely, 0%, 0.5% and 1%, and mangosteen pericarp extract consisted of two levels, namely, 0% and 1%. Plant height, leaf area, yield components and pod yield were analysed by univariate variance and Duncan's multiple range test at 5% significance level. The results showed that the increase in salinity stress reduced the leaf area, plant height, yield components and yield of mungbean. However, the use of mangosteen pericarp extract could increase the plant height, leaf area, yield components and yield of mungbean. The weight reduction of 100 mungbean seeds at 1% salinity stress could be alleviated by the application of 1% mangosteen pericarp extract. Moreover, mangosteen pericarp extract could mitigate mungbean yield loss caused by salinity stress.
