Abstract
The present investigation entitled “FOLIAR SPRAY OF GA3 ON MORPHO-PHYSIOLOGICAL TRAITS AND YIELD OF GLADIOLUS” was conducted during rabi 2023-24 at the Department of Plant Physiology, Agricultural Biochemistry, Medicinal and Aromatic Plants, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh). Five treatments were used in the experiment, which included four concentrations of gibberellic acid (foliar application) along with the control. A Complete Randomized Design (CRD) with three replications. A single application of 160 ppm GA3 had a significant effect on a number of characteristics, such as the plant height, the number of leaves per plant, the number of corm sprouting plants, the number of flowers per plant, the number of days before the first flower initiation, 50% flowering, and flower diameter, growth and phenology parameters such as flowering time and number of florets per inflorescence also increase and yield parameters like corm diameter, weight of corm per plant, yield of spike, yield of corm, and flower yield showed significant increased.
