Abstract:
A Field experiment was conducted at Vegetable Research Station, SKLTSHU, Hyderabad during Rabi 2018-19 with 21 varieties supplied by Directorate of Onion and Garlic Research (ICAR), Rajgurunagar, Maharashtra. Six week old seedlings of 21 varieties were transplanted in flat beds at a spacing of 15 x 10 cm in a plot of 3 x 2 meter size in randomized block design with three replications to identify suitable onion variety for Rabi season. The results revealed that Maximum average weight of single bulb was recorded in L-355 (C) (NHRDF Red-2) (131.13 g) is on par with Bhima Shakthi (C) (129.63 g) followed by Bhima Kiran (c) (109.47 g), DOGR-WHY-2 (MS 100 X W-361) (108.59 g) which are on par with each other and minimum was recorded in DOGR Hy-8 (38.27 g). Highest Marketable yield/ha was observed in L-355 (C) (NHRDF Red-2) (419.62 q) is on par with Bhima Shakthi (C) (414.80 q) followed by Bhima Kiran (c) (350.29 q), DOGR-WHY-2 (MS 100 X W-361) (347.48 q). The Probable reason for increased fresh weight of bulb per plant due to humus substances could have mobilized the reserve food materials to the sink through increased activity of hydrolyzing and oxidizing enzymes.
