Effect of micronutrients on plant growth, flowering and corm production of Gladiolus cv. summer sunshine

Abstract

An investigation to study the “To study the effect of micronutrients on plant growth, flowering and corm production of Gladiolus cv. summer sunshine” was conducted in Rabi season during the year 2020-21 at Horticulture Research cum Instruction Farm, Floriculture and Landscape Architecture Department, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. Four micronutrients ZnSO4, H3BO3, CuSO4, FeSO4 and its interaction effect at various concentrations with foliar spraying method in addition to this experiment's control included eleven treatments. The experiment was designed with a Randomized block design (RBD) and three replications. The application of micronutrient (ZnSO4 0.4 + H3BO3 0.4 % + CuSO4 0.4 % + FeSO4 0.4 %) with foliar spray (T11) was initiate to be most successful for superior performance of different parameters such as days taken to 50 % sprouting, plant height, maximum number of shoots per mother corm, leaf width, days to open first floret, spike length, rachis length, internodal length between florets, floret diameter, amount of florets per spike, diameter of floret, vase life and yield attributes like quantity of cormel per plant, weight of cormels per plant, number of cormels per plot, weight of cormels per plot, number of leaves per plant, time to spike emergence, days to 50 % floret open, number of floret per spike, maximum number of corm, diameter of corm per plant. Whereas treatment T10 (ZnSO4 0.2 % + H3BO3 0.2 % + CuSO4 0.2 % + FeSO4 0.2 %) found to be more successful for enhanced performance of other attributes such as length of leaves, flowering duration, weight of corm per plant, weight of corm per plot.
