Integrated Nutrient Management During Cultivation Improves Coriander Seeds Storability

Le résumé fourni par la source

Crop production, human nutrition, and food security all rely on seeds; thus, seed quality and storability are important factors in seed performance. The vigor of seeds determines their capacity to germinate and establish seedlings quickly, evenly, and robustly under a variety of climatic conditions. The present study evaluated seed quality after field application of organic manures, bio-fertilizers, and chemical fertilizers in 18 treatment combinations along with a control (2016–2020). The freshly harvested coriander seeds (cv. Hisar Bhoomit) were stored for 18 months in plastic containers at room temperature, and various seed quality parameters were evaluated at six-month intervals. As the storage period increased, significant reductions in seed quality parameters were observed. The combined application of inorganic fertilizers, organic manures, and bio-fertilizers significantly improved the seed quality parameters during storage, compared to inorganic fertilizers, organic manures, and bio-fertilizers applied alone. Seed treatment with Azotobacter, PSB, and the application of vermicompost (equivalent to 100% RDN) during coriander seed production resulted in significantly higher standard germination (66.33%), seedling length (17.89 cm), seedling dry weight (2.52 mg), vigor index-I (1186), vigor index-II (166.69), and germination after accelerated aging (26.67%) after 18 months of ambient storage of seed. The study highlighted that the use of vermicompost for fulfilling the recommended nitrogen dose worked best when used in combination with bio-fertilizer (Azotobacter and PSB) for maximizing the storage capacity of coriander seed in comparison to the other treatments.
