Effect of Pre-sowing Seed Treatments and Synthetic Polymer Coating on Seed Quality and Storability in Redgram (Cajanus cajan. L.)

Successful agriculture depends on high-quality seed, which is a fundamental and important ingredient. Under unfavourable environmental conditions like drought, pre-sowing seed treatment such as coating priming could boost the germination seedling vigour. The agents often include plant growth regulators, micro-fertilizers, pesticides, insecticides. present investigation was carried out to assess impact of polymer quality parameters pigeon pea cv PRG 176 during 2018 2021 at Seed Research Technology Centre, Rajendranagar, Hyderabad. trail laid in randomized block design with four replications. Freshly harvested redgram variety Ujwala Seeds were treated for hardening ZnSO4 @100ppm + Polymer 3ml/kg Bavistin 2g/kg Imidacloprid 1ml/kg Pseudomonas fluorescens 10 g/kg Rhizobium different combinations. seeds shade dried, packed gunny bags, stored room temperature various treatments metrics under ambient storage conditions. results bimonthly observations showed that there substantial differences between characters study. T7 recorded highest percentage (98 70.67), speed emergence (12.1 10.1), electrical conductivity (0.169 0.292), shoot length (14.9 8.65cm), root (14.5 8.52cm), (29.4 17.17cm), fresh weight (5.55 2.5g), dry (0.40 0.21g), vigour index-I (2881 1213), Vigour Index-II (53.9 14.84) over other study initiation studies (2MAS) 28 months period respectively. current study's findings greatly outperformed all characters, maintaining an optimal (70.67%) even up
