Osmoconditioning Menggunakan Ekstrak Daun Kelor untuk Meningkatkan Vigor dan Hasil Kedelai Edamame Glycine max (L.) Merr.

Edamame is a plant that has the potential to be developed because it contains many benefits, however, edamame production yields are still low. One of the causes of the decline in edamame production is due to low seed quality and deterioration due to storage factors. This study aims to examine the effect of osmoconditioning treatment and Moringa leaf extract in increasing the vigor and viability of deteriorated edamame seeds. This research was conducted at the UMM Agrotechnology Laboratory and Open Land on Jl Raya Tlogomas. This research used a simple Randomized Complete Group Design (RKLT), which consisted of 4 replications and 6 treatments, each treatment consisting of 3 samples, so that a total population of 72 samples was obtained. while the osmoconditioning treatment was carried out using 25 seeds in one growth medium and repeated 4 times. So the total seeds used were 600 seeds. The treatments used were without soaking, water soaking, 10% Moringa leaf extract, 20% Moringa leaf extract, 30% Moringa leaf extract, and 40% Moringa leaf extract. Observation variables carried out in this research included viability tests after and before treatment, water content, plant height, number of leaves, 50% flower emergence, 50% number of pods and number of pods per plant. The results of research on edamame which had undergone deterioration showed that the average germination capacity of edamame seeds was the highest after being given treatment, namely in the 20% Moringa leaf extract soaking treatment of 81.28% when compared to without soaking of 55.08% with the highest vigor of 55.83. % when compared with the control, namely 37.25%, maximum growth potential 81.33%, growth simultaneity 71.00% and growth speed 26.47% %/etmal. Meanwhile, the results of field survival tests showed that the Moringa leaf extract concentration of 20% had the highest average, namely plant height of 31.95 cm, number of leaves 26.58, flowering age 50% 44.58 HST, pod formation 50% 53.8 DAP and the number of pods planted was 15.6 and the weight of the pods planted was 14.30 g. This was caused by providing osmoconditioning treatment using Moringa leaf extract which contains the cytokinin hormone 218.88 ppm, the auxin hormone 73.53 ppm and the gibberellin hormone 61.12 ppm. These hormones play an important role in the plant growth process, which plays a role in influencing root growth and differentiation, encouraging cell division and general growth, encouraging germination and delaying senescence, as well as elongation of plant shoot or bud cells, spurring the development of vascular tissue and encouraging cell division in vascular cambium thereby supporting the growth of stem diameter.
