| dc.description.abstract | Field and laboratory experiments were conducted to find out the effect of growing condition, spacing and calcium sprays on seed yield, quality and storability of tomato seeds in National Seed Unit, UAS, Dharwad. Field experiment was conducted in split-split design consisted of two growing conditions viz., open field and naturally ventilated polyhouse condition with three levels of spacing viz., 60 x 45 , 60 x 60 and 60 x 75 cm and four stages of calcium sprays viz. control, weekly, fortnightly and monthly spray. Between two growing conditions, polyhouse grown condition recorded significantly higher seed yield (477.85 kg/ha), germination (87.91 %) and vigour index (1149) compared to open field. Among the spacings, higher seed yield (465.28 kg/ha) with better seed quality traits were recorded with 60 x 60 cm spacing. The higher seed yield (450.98 kg/ha) was recorded with fortnightly calcium spray. In polyhouse condition, among the calcium sprays, higher 1000 seed weight (2.62 g) and better seed quality traits were recorded with fortnightly calcium spray. Among five pickings, second picking recorded higher germination (96.45 %) and vigour index (1352). The storage experiment was conducted with the seeds produced under two growing condition viz., open field and polyhouse, and six seed treatments viz., control and seed treatment with chemicals like thiram, vitavax power @ 2g/kg of seeds, polymer coating @ 20ml/kg of seeds, thiram @2g + polymer coating @ 20ml/kg of seeds and vitavax power @ 2g + polymer coating @ 20ml/kg of seeds and stored under ambient condition for 6 months period. Between growing conditions, polyhouse grown seeds recorded higher germination (75.35 %) and vigour index (1373) compared to open field at the end of 6 months storage period. Among the seed treatments, vitavax power and polymer coated seeds retained higher germination (76.38 %) and other seed quality parameters. | en_US |
