| dc.description.abstract | Two field and laboratory experiments were conducted to find out the effect of manual seed dropping heights and seed treatment with biofertilizers and calcium salts on crop growth, seed yield, quality and storability in soybean varieties in Department of Seed Science and Technology, University of Agricultural Sciences, Dharwad. Field experiment was conducted in split-split design consisted of three soybean varieties viz., JS-335, JS-9305 and DSb-1(with three levels of seed dropping heights viz. no dropping, six feet dropping and nine feet dropping heights and two biofertilizer seed treatments viz. Rhizobium and Rhizobium + PSB. Among three varieties DSb-1 variety recorded higher seed yield (2106.1kg/ha), germination (91.25%), vigour index (3746) and other seed quality parameters compared to JS-9305 and JS-335. Among the dropping heights, higher seed yield (2160.5 kg/ha) with better seed quality traits were recorded in the undropped seeds compared to nine feet dropped seeds. The maximum seed yield (2024.6kg/ha) was recorded in the seed pretreated with rhizobium+PSB compared to Rhizobium alone. The interaction between varieties, seed dropping heights and biofertilizers was found non significant for all the test parameters studied. The second storage experiment was conducted with above said soybean varieties, dropping heights and seed treatment with calcium salts (untreated control, calcium chloride and calcium carbonate) stored under ambient conditions for 12 months period. Among varieties, DSb-1 variety recorded higher germination (33.33%), vigour index (812) and less mechanical damage compared to JS-335 and JS-9305 varieties at the end of 12 months storage period. The undropped seeds have retained higher germination (70.68%), vigour index and other seed quality parameters compared to nine feet dropped seeds during entire storage period. Among seed treatments, calcium chloride treated seeds retained higher germination (34.27%) and other seed quality parameters followed by calcium carbonate compared to untreated seeds at the end of 12 month storage period. | en_US |
