Effect of GA3 and Potassium on Growth and Yield in Red Radish (Raphanus sativus L.) under Subtropical Conditions of Jammu

An experiment was carried out at Vegetable Experimental Farm, Division of Vegetable Science, SKUAST Jammu during Rabi season of 2022-2023. The experiment was laid out under factorial RBD design with three replications comprising of sixteen treatments. The treatments consisted of four doses of Potassium i.e., 40, 50, 60 and 70 kg/ha and four concentrations viz. 0,100,200 and 300 ppm of GA3. The growth and 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 (112.42 q/ha) were recorded with 200 ppm GA3 application. 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 (92.31 q/ha), were recorded with 50kg/ha K2O application. However; highest root length (19.20 cm), number of leaves/root (14.87), root weight (226.14 g), shoot weight (123.54 g), root-shoot ratio (2.10), fresh root shoot yield (115.90 q/ha) were recorded with treatment combination G3K2 (200 ppm GA3 + 50 K2O/ha). Based on the investigation, it can be concluded that the application of 200 ppm GA3 at 30 days after sowing with 50 kg potassium/ha resulted in the highest growth parameters and yield

Effect of different Potting Mixtures on Acclimatization of In vitro Developed Plants on Survival Percentage under Glass House Condition

The experiment was conducted during the years 2020-22, all of the experiments for the current research were carried out in the Plant Tissue Culture Laboratory, Department of Plant Molecular Biology & Biotechnology, College of Agriculture, Gwalior, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M. P.). Pomegranate cv. Bhagwa plantlets were placed in polythene bags containing various potting mixtures, such as soil, FYM, and Vermicompost, alone and in various combinations. The hardened plantlets were then exposed to direct sunshine to help them acclimate to their new surroundings. The percentage of tissue culture plantlets that survived was calculated. Experiments were conducted in a Completely Randomized Design (CRD) with four replications of each treatment and each replication contain three explants. Data were analyzed using Duncan’s multiple range test whereas the survival percentages were analysed by arc-sine transformation. On the basis of present study it is concluded that cocopeat soil combination had the highest survival rate (95.00%), followed by cocopeat (85%). In the case of pomegranate, sand, perlite, vermiculite, vermiculite soil and perlite sand alone were not shown to be effective hardening materials because all of the plants withered within a week. After two months of hardening under polyhouse circumstances, cocopeat soil showed the greatest growth with a notable increase in plant height (37.23 cm), followed by cocopeat (33.03 cm). Therefore, we may conclude that cocopeat is the ideal material for pomegranate plants that have been produced in vitro
