Abstract
This study investigates the efficacy of diverse seed protectants on key parameters affecting seed quality and pest infestation in pigeon pea seeds during storage. Over 3, 6, and 9-month storage periods, the impact of seed protectants on germination percentage, moisture content, vigor index, insect infestation by pulse beetles, and seed weight loss was assessed. Notably, Emamectin benzoate and Deltamethrin consistently maintained high seed quality, with germination percentages ranging from 88.33% to 84.33% and 87.33% to 83.00%, respectively. These insecticidal treatments also exhibited minimal insect infestation, ranging from 0.33% to 1.00%. In contrast, botanical protectants showed varying effectiveness, with Lantana camara and Vitex negundo displaying germination percentages ranging from 86.67% to 80.67% and 87.00% to 82.67%, and insect infestation levels ranging from 0.33% to 1.33%. These findings highlight the importance of seed protectants in preserving seed viability and minimizing pest damage during storage, thereby enhancing crop yield and reducing post-harvest losses in pigeon pea cultivation.
