Effects of seed priming with gibberellic acid (GA₃) on growth, yield and quality attributes of radish (Raphanus sativus) grown under soil-less medium

Seed priming is a pre-sowing seed treatment that has gained significant attention in recent years due to its potential to improve seed germination. With increasing scarcity of water availability, land shortage problem and seed germination is challenging under stress conditions. These aforementioned challenging have been attracting the global attention towards early germination with better productivity. Thus, the purposeful objective of this experiment was to evaluated the effects of seed priming techniques on radish crop by using various levels of GA₃ concentration under soil-less medium. An experiment was conducted during September to November 2022–2023 at DIBER, DRDO, Haldwani, Nainital (Uttarakhand). Results revealed that maximum plant height (62.27 cm) , leaf length (38.33 cm), root length (29.27 cm), root width (6.80 cm), girth of root (8.93 cm), edible length of root (13.57 cm), total yield per plant (342.00 g), yield of root/plant (234.00 g), yield of leaf/plant (112.00 g), dry wt. of root (45.37 g), dry wt. of leaf 10.69(g), TSS (9.00), and chlorophyll content (50.93) found in T₁ (GA₃ 10 ppm with 1 hours) while highest number of leaf (11.67), Germination % (84) was observed in T₃ (GA₃ 30 ppm with 3 hours).
