Abstract:
The study entitled “Effect of seed pelleting on longevity of onion (Allium cepa L.) seeds during storage” was carried out from summer 2020 and onwards at the Seed Testing Laboratory, Department of Seed Science and Technology, College of Agriculture, Junagadh Agricultural University, Junagadh. The experimental material comprised of different seed pelleting treatments [P₁: Raw seed (absolute control), P₂: Standard pellet (Control) (Carbandazim), P₃: Thiamethoxam, P₄: Seed priming + standard pellet, P₅: Nano nutrition (Zn, Fe), P₆: Biostimulant mixture, P₇: Biological (Bacillus spp.), P₈: Micronutrients mixture 1 (Regular phosphorus, manganese, sulphur, copper, zinc and molybdenum) and P₉: Micronutrients mixture 2 (Nano phosphorus, potassium, manganese, sulphur, copper, zinc and molybdenum)] were evaluated. After seed pelleting treatments, the seeds were stored in cold storage conditions and the observations on germination percentage and seed vigour parameters were recorded at two months interval up to fourteen month of storage (up to germination went down below 70%). The results were analyze using Completely Randomized Design. After fourteen months of storage, significantly the maximum germination (80.33%), seedling length (10.59 cm), seedling dry weight (14.64 mg), seedling vigour index I (850.41) and seedling vigour index II (1176.16) was recorded in seeds pelleted with micronutrient mixture 2 (P₉: Nano phosphorus, potassium, manganese, sulphur, copper, zinc and molybdenum), while it was recorded lower (15.00%, 3.42 cm, 2.93 mg, 50.80 and 58.95, respectively) in seed priming and seed pelleting (P₄).
