Enhancing Planting Value of Marginal Seed Lots of Blackgram through Hydration-Dehydration (HD) Treatment
Year: 2015
Type: article
Abstract: Seed invigoration is being utilized as a technique for enhancing quality of aged seeds.In pulses seed hardening is one technique involves Hydration Dehydration (HD).This study was conducted to investigate the response of seeds with marginal germination percentage of two varieties of blackgram (APK 1 and VBN 3), to hardening which consisted of soaking seeds in water/bio active solutions for 4 h and drying to initial moisture content.Seed quality assessment inferred that seed hardening generally improved seed germinability and vigor, seed response varying significantly with variety and initial vigor level.Excellent results were obtained in water soaked seeds rather than organics.Among organics, Prosopis leaf extract at 2% excelled in improving seed quality of aged seeds.Seed hardening is advantageous in two ways 1. Resource poor farmers could benefit from this cash-free technique and 2. Reduced seed rate of marginal seed lot.
