 ABSTRACT

The field experiment was during rabi 2017-18 to determine the effect of harvesting stages on quality of chickpea, wherein six different varieties of chickpea (V1 = GG 1, V2 = GG 2, V3 = GJG 3, V4 = GG 4, V5 = GG 5, and V6 = GG 6) were harvested at different stages (H1 = Dark green colour pod stage, H2 = Green to yellow colour pod stage, H3 = Full yellow colour pod stage, and H4 = Copper brown colour pod stage). The seeds harvested as per the treatment combinations from the field experiment were stored in the laboratory for eight 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 (length), seedling vigour index (mass) and electrical conductivity of seed leachates (ds/m) were recorded initially at the time of storage and after eight 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, and seedling vigour index (length and mass) were decreased gradually with increased in storage period. Irrespective of varieties, the seeds harvested at dark green colour pod stage (H1) were not germinated at all. Therefore, no any seed quality observations were recorded. Irrespective of varieties, the moisture content in the seeds, 100 seed weight and electrical conductivity of leachates were increased gradually with increased in storage period, while germination, seedling length, seedling fresh and dry weight, and seedling vigour index (length and mass) of seeds harvested at different stages were decreased gradually with increased in storage period. It was suggested that for getting the higher yield and quality of chickpea varieties after eight months of storage, chickpea seed should be harvested at the H3 (full yellow color pod stage), as the seeds harvested at full yellow color pod stage recorded the germination percentage (84.67 %) even after eight 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.
