چکیده

This study investigates the impact of various harvesting techniques and seed moisture levels on the yield and quality of mung beans, aiming to optimize production efficiency through a better understanding of mechanical and physiological interactions. The research identified that manual harvesting at 20% seed moisture achieved the highest yield of 1012.20 kg ha⁻¹, a result primarily driven by the synergy between gentler manual handling and decreased mechanical friction at higher moisture levels, which effectively prevented pod shattering and minimized grain loss during collection. Conversely, the lowest yield of 946.80 kg ha⁻¹ was recorded during direct combine harvesting at 12% moisture; this significant decline is attributed to the increased brittleness of drier seeds, making them highly susceptible to mechanical impact and breakage under high-speed machine operation, which consequently elevated both shattering losses and product impurities. These findings demonstrate that the interaction between harvesting methods and moisture content significantly influences grain integrity, highlighting that aligning mechanical intervention with seed physiology is crucial for maximizing output. Consequently, adopting evidence-based harvesting practices that account for these underlying biological and mechanical mechanisms is essential for enhancing the overall productivity and sustainability of mung bean cultivation.
