Effect of Different Indigenous Natural and Plant Products on Storability of Groundnut (Arachis hypogaea L.) Seeds

Abstract

Post-harvest losses of groundnut (Arachis hypogaea L.) due to insect pests, fungal contamination, and deterioration in seed quality remain major challenges in sustainable storage systems. Indigenous natural and plant-based products offer eco-friendly alternatives to chemical protectants. A controlled laboratory study was conducted for two consecutive years to assess the effects of Neem Seed Kernel Powder (NSKP), Pungam Seed Kernel Powder (PSKP), Asafoetida Powder (AP), and Pepper Powder (PP), both individually and in combination, on the storability of groundnut. The combination treatment (NSKP + PSKP + AP + PP) was compared with individual treatments and a control. Observations were recorded on seed damage, number of eggs laid, number of live adults, fungal incidence, and seed germination. Results revealed that the combined treatment recorded the lowest seed damage (2.0%), minimal eggs laid (10.6), and fewest live adults (0.3) after 60 days of storage, with reduced fungal incidence (3.5%) and highest germination (90%). The study demonstrates that indigenous botanical mixtures effectively protect stored groundnut seeds in an eco-friendly and sustainable manner.
