摘要

Seed priming and organic foliar applications have emerged as effective, eco-friendly strategies to enhance the establishment and productivity of leguminous crops. The study was conducted over a single growing season in 2024, comprising two experiments aimed at evaluating the effects of various natural extracts on germination, seed establishment, and yield, with the goal of identifying an optimal organic biostimulant treatment for this important legume crop. A laboratory trial used a Completely Randomized Design (CRD) with 16 treatments and three replications to screen priming agents, including distilled water, lemon juice, aloe vera gel, tomato fruit extract, and beri leaf extract at varying concentrations. Organic priming significantly improved all germination and seedling vigour parameters compared to the control. The 5% aloe vera gel treatment (T4b) proved superior in this initial screening, achieving 95% germination, the shortest mean germination time (T50: 2.4 days), the highest germination index (14.5), and the best seedling vigour (vigour index: 1902). Based on these laboratory results, a subsequent field experiment employed a Randomized Complete Block Design (RCBD) with six treatments and three replications to evaluate foliar application of the most promising extracts on growth and yield parameters under actual field conditions. Field results confirmed the laboratory findings, with 5% aloe vera foliar application producing the tallest plants (67.5 cm), highest pod count (50.3 per plant), and maximum grain yield (1670 kg ha−1), biological yield (4550 kg ha−1), and harvest index (41.44%). The study demonstrates that organic seed priming and foliar application with 5% aloe vera gel significantly enhances mungbean performance across both laboratory and field conditions. Aloe vera is identified as an optimal organic biostimulant, providing a viable, eco-friendly alternative to synthetic inputs for improving crop establishment, growth, and ultimate productivity in sustainable legume cultivation.
