Abstract
The present study aimed to evaluate the effect of foliar nano-fertilizers on the growth and flowering of okra (Abelmoschus esculentus) during the Zaid seasons of 2022-23 and 2023-24 at the Vegetable Research Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur. A Factorial Randomized Block Design with 15 treatment combinations and three replications was employed, utilizing five major nutrients and three levels of micronutrients. The combination of 75% recommended soil applied NPK with foliar nano NPK (4 ml/L) and nano Zn and Fe (1g/4L) showed maximum improvements in growth parameters, including plant height (120.35cm), number of leaves/plant (55.38), number of nodes/plant (15.30), number of branches/plant (4.61), stem diameter (2.77cm) and minimum inter-nodal length (7.67cm) and flowering traits such as earlier first flowering (39.88 days), days to 50% flowering (44.36days) and increased flower production (22.60 flowers/plant).
