Abstract
An experiment entitled, "Effect of GA3and Potassium on the Yield and Quality SeedProduction in Red Radish (RaphanussativusL.)" was carried out at Vegetable ExperimentalFarm, Division of Vegetable Science, SKUAST Jammu during Rabi season of 2022-2023. Theexperiment was laid out under factorial RBD design with three replications comprising of sixteentreatments. The treatments consisted of four doses of Potassium i.e., 40, 50, 60 and 70 kg/ha and fourconcentrations viz. 0, 100, 200 and 300 ppm of GA3.
The growth and seed yield parameters maximum viz. shoot length (34.15 cm), root length(18.73 cm), number of leaves/root (14.30), root weight (220.49 g), shoot weight (119.47 g), root-shoot ratio (2.04), fresh root shoot yield (98.75 q/ha) plant height (183.24 cm), plant spread(112.73 cm), number of siliqua/plant (548.67), number of seed/siliqua (6.25), length of siliqua(5.90cm),1000-seedweight(9.55g),seedyield/plant(18.09g),seedyield/ha(2.19q/ha),germination percentage (93.13%), seed vigour index (249.06), minimum days to 50% flowering (42.44days) and days to seed harvest (111.79 days), were recorded with 200ppm GA3application. Similarly, highest shoot length (29.06 cm), root length (17.53 cm),number of leaves/root (11.18), root weight (171.67 g), shoot weight (104.84 g), root-shoot ratio(1.87), fresh root shoot yield (92.06 q/ha), plant height (150.51 cm), plant spread (104.09cm), number of siliqua/plant (548.67), number of seed/siliqua (5.55), length of siliqua (5.13 cm),1000 seed weight (9.12 g), seed yield/plant (15.16 g), seed yield/ha (1.88 q/ha), germination(86%),seed vigourindex(200.12)&minimum days to 50% flowering (47.93 days),minimum days to seed harvest (118.66 days)wererecordedwith 50kg/ha K2O application.
However;highestrootlength(19.20cm), number of leaves/root(14.87),rootweight(226.14 g), shoot weight (123.54 g), root-shoot ratio (2.10), fresh root shoot yield (103.58 q/ha), number of siliqua/plant (555), number of seed/siliqua (6.33), length of siliqua (6.03 cm),1000-seed weight (9.80 g), seed yield/plant (18.50 g), seed yield/ha (2.26 q/ha), germination(95%), seed vigour index (255.33)& minimum days to 50% flowering (41.35 days), minimum days to seed harvest (109.35days) were recorded with treatment combinationG3K2(200 ppmGA3+ 50 K2O/ha). On basis of economics of the treatment combinations G3K2the highestgrossreturn(429900 /ha),netreturn(298389 /ha)and B:C ratio of 3.27.
