Abstract:
A field experiment was conducted at Vegetable Research Station, SKLTSHU, Hyderabad, Telangana State, India during August, 2020 - January, 2021 to study the performance of white onion varieties under late kharif conditions in Southern Telangana. Experiment was conducted with five entries Bhima Safed, Bhima Shweta, Bhima Shubra, W-355 and W-361. The experiment was laid out in Randomized Block Design replicated four times. The predominant bulb colour and bulb shape of all the five varieties is white and round. High amount of uniformity in bulb size was noticed in W-361. Among the five entries tested, W-361 recorded significantly higher mean bulb weight (86.69 g), marketable yield (44.88 t ha^-1) and total yield (45.95 t ha^-1) over other entries followed by Bhima Shubra (82.71 g, 42.72 & 43.84 t ha^-1) and W-355(76.33 g, 39.05 & 40.61 t ha^-1). Highest TSS (11.35 ⁰Brix) was observed in the variety W-355 followed by Bhima Safed and Bhima Shweta. No double bulbs were observed in W-355, Bhima Safed and Bhima Shubra. Least number of bolter bulbs was noticed in W-355 followed by W-361. Zero percent rotten bulbs were recorded in Bhima Safed, Bhima Shubra and W-361. Least incidence of thrips was noticed in Bhima Shweta followed by Bhima Shubra and W-361. Least incidence of purple blotch observed in Bhima Safed followed by Bhima Shubra and Bhima Shweta.
