Sprouting susceptibility in mung bean is influenced by both morphological and physiological factors. Dormancy, a natural mechanism that delays germination under adverse conditions, is crucial in mitigating pre-harvest sprouting. Varieties lacking dormancy traits are particularly vulnerable, as their seeds are more prone to absorbing moisture and initiating germination prematurely.
The objective was to evaluate the effects of these treatments on key agronomic traits such as pod production, seed size and seedling growth, with a focus on improving seed quality and dormancy resistance. Field trials were conducted using 10 varieties obtained from ICAR-IIPR, Kanpur using 7 treatments during the Kharif 2022–23 following field trials in augmented block design at the Crop Research Centre of Rabindranath Tagore University and laboratory experiments were conducted in the Botany Research Laboratory at Rabindranath Tagore University, Raisen in factorial completely randomized design (FCRD) for evaluation of material.
The results demonstrated that GA3 (T1) had the most significant positive effect across all cultivars, with the highest pod counts (e.g., V1T1; 40.45 pods) and seed sizes (e.g., V1T1; 3.37 mm horizontal seed size). Other treatments, such as IAA (T6) and KNO3 (T5), also showed substantial improvements in pod production and seed development. In contrast, MH (T4) and ABA (T2) significantly reduced pod formation (e.g., V1T4; 11.25 pods), seed size and overall seedling growth, indicating their potential to induce dormancy and inhibit growth. The study concludes that GA3, IAA and KNO3 can be effectively used to enhance mung bean productivity, while MH and ABA should be carefully managed due to their suppressive effects. These findings have practical implications for improving seed quality and dormancy resistance in mung bean cultivation.
