 ABSTRACT

The present investigation was conducted at the Instructional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh during kharif-2018, with an aim to study the effect of harvesting stages (H₁=One pod mature in plant, H₂=Physiological maturity, H₃=One week after physiological maturity, and H₄=Two weeks after physiological maturity) on seed quality in different soybean varieties (V₁=GS-1, V₂=GS-2 and V₃=GJS-3) in the storage condition. The seeds harvested as per the treatment combinations from the field experiment were stored in the laboratory for six months and observations viz., moisture content (%), 100 seed weight (g), germination percentage, seedling length (cm), seedling fresh weight (mg), seedling dry weight (mg), seedling vigour index-I, seedling vigour index-II, electrical conductivity of seed leachates (ds/m) and oil content (%) were recorded initially at the time of storage and after six  months of storage in the laboratory of the Department of Seed Science and Technology, College of Agriculture, Junagadh Agricultural University, Junagadh. Irrespective of the harvesting stages, the moisture content in the seeds, 100 seed weight and electrical conductivity of seed leachates were increased gradually with increased in storage period, while germination, seedling length, seedling fresh and dry weight, seedling vigour index (I and II) and oil content (%) were decreased gradually with increased in storage period. It was suggested that for getting the higher yield and quality of soybean varieties after six months of storage, soybean seed should be harvested at the H₂ (Physiological maturity stage), as the seeds harvested at physiological maturity stage recorded the germination percentage (77.23 %) even after six months of storage with good vigour. For maintaining better quality up to the next season sowing, seeds could be stored under proper storage condition, because with increase in storage period, quality of seed deteriorated.
