Abstract :
The research was carried out for 4 months from March 2019 to June 2019. The purpose of the study was to determine the effect of interactions and the main factors of NaCl and legin on the growth and production of mung beans. The design used in this study was a factorial completely randomized design (RAL) consisting of two factors. The first factor is the factor N (NaCl) which consists of four levels of treatment, namely: 0, 0.5, 1, 1.5 g / l of water and the second factor is L (Legin) consisting of four levels of treatment, namely: 0, 5, 10, 15 g / kg of seeds to obtain 16 treatment combinations, where each treatment was repeated three times, so that there were 48 experimental units. The parameters observed in this study were the relative growth rate, the rate of assimilation, the number of effective nodules of 28 days, the weight of nodules, age of flowering, age of harvest, weight of seeds planted and weight of 100 seeds. The results showed that the interaction of NaCl and Legin was significant with respect to: relative growth rate, wheezing assimilation rate, effective number of root nodules 28 days and the weight of seeds planted. The best treatment is the combination of NaCl 0 g / l of water and 10 g of kg legin seeds. The main effects of NaCl were evident on: relative growth rate, rate of assimilation, number of root nodules 28 days, root nodule weight, age of flowering, age of harvest, weight of 100 seeds and weight of seeds of planting. The best treatment is the treatment of 0 g / l water without administration of NaCl. The main effects of legins were evident on: relative growth rate, rate of assimilation, number of effective root nodules 28 days, root nodule weight, age of flowering, age of harvest, weight of seeds planted and weight of 100 seeds. The best treatment is legin with a dose of 10 g / kg of seed
