Mung beans, an economically and nutritionally valuable leguminous crop, adapt well to various environmental conditions. Neem leaf extract (NLE) boasts bioactive compounds in crops. Different studies demonstrate a positive interaction between its use in drought conditions and increased plant growth, biomass production and stress tolerance, providing sustainable agricultural practices and crop resilience. NLE played significant roles in the experiments to check different parameters i.e., germination rate, shoot and root dry weight, no. of pods per plant, 100 seed weight, Biological Yield, Grain Yield and harvest index. In germination Rate, NLE5-FC100 treatment demonstrated the highest germination rate at 100%; on the other hand, NLE20-FC30 achieved 80.95% germination. In Shoot Dry Weights, NLE5-FC100 treatment resulted in the highest average shoot dry weight at 10.643, while NLE10-FC30 had the lowest at only 4.6443 grams per square meter. In Root Dry Weight, NLE5-FC100 treatment had the highest dry root weight at 1.3436; NLE10-FC30 had 0.6288. NLE5-FC100 treatments had the highest number of pods per plant (12.33), while NLE10-FC30 treatments produced three pods or fewer per plant (3.33). In 100 Seed Weight, NLE5-FC100 treatment recorded the highest 100 seed weight at 7.33, while NLE20-FC30 produced 3.21 seeds per plant. In Biological Yield, NLE5-FC100 treatment had the highest biological yield at 20.165; while NLE10 FC30 produced the lowest yield with 6.155. In Grain Yield, NLE5-FC100 treatment yielded the highest grain yield at 8.1178 while NLE10-FC30 produced only 0.7969 of grain yield. In Harvest Index, NLE5-FC100 treatment had the highest harvest index at 40.371, while NLE5-FC30 achieved 11.08 as its minimum index value. This study concluded that 5x Dilution leaf extract possesses stronger bio stimulant capabilities than other Dilutions; thus, enabling Mung bean seeds to produce more seeds and lessen drought stress effects.
