Description |
Laboratory and field experiments were conducted to standardize the optimum duration for soybean seed priming and to study the effect of seed quality and seed priming chemicals on storability, seed yield and quality of soybean Cv. JS – 335 at Seed Research Laboratory, National Seed Project (Crops), University of Agricultural Sciences, Dharwad and at Water and Land Use Management Institute (WALMI) Farm, Dharwad, respectively. The lag phase (Phase-II) with little change in water content from 41.8 to 45.0% (14, 16 and 18 h) was found as a priming regime. The 14 h priming duration showed consistently higher performance with the quality tests. Significantly higher germination (98.00-66.00 %), field emergence (94.90-58.79 %) and vigour index (3118-1418) were recorded in seeds of higher quality primed with CaCl2.2H2O (0.5%) followed by GA3 (20ppm) and KH2PO4 (50ppm) primed seeds. Lower electrical conductivity were recorded in the seeds of higher quality primed with CaCl2.2H2O (0.5%) (0.214 - 1.471 dSm-1) during the storage period. Significantly lower days to 50 % emergence was recorded in seeds of higher quality primed with GA3 (20ppm) (6.00) which was on par with the same seeds primed with CaCl2.2H2O (0.5%) (6.67). Significantly higher field emergence (93.00 %) was recorded in seeds of higher quality primed with CaCl2.2H2O (0.5%) which was on par with seeds of higher quality primed with GA3 (20ppm) (92.00 %). Significantly higher yield per ha (23.67 q) was recorded in the plots sown with seeds of higher quality primed with CaCl2.2H2O (0.5%), followed by those plots with GA3 (20ppm) and KH2PO4 (50ppm). Seed yield (q/ha) showed high positive and significant correlation with number of pods per plant (0.909**), number of seeds per pod (0.933**) and yield per plant (0.921**). Seed quality parameters were significantly higher in the progeny seeds harvested from lower quality seed primed with CaCl2.2H2O, GA3, and KH2PO4. |
