Abstract:
An experiment took place at the experimental farm of the Main Vegetable Research Centre, Anand Agricultural University, Anand. This occurred during the winter crop season of the years 2019-20 and 2020-21 to investigate the impact of micronutrients and a plant growth regulator on the growth of onions. The twelve different treatments were examined using a Randomized Block Design with three replications. The results of the experiment indicated that applying micronutrients and a plant growth regulator through the leaves led to enhancements in both physiological and yield characteristics. Among the application of micronutrients and growth regulators, the greatest value of physiological parameter like plant height, number of leaves, leaf length, total dry matter, AGR, CGR, RGR and total chlorophyll were recorded from foliar application of Zn (1 g/l) + GA₃ (100 mg/l) followed by Zn (1 g/l) + Fe (1 g/l). The foliar application of Zn and GA₃ also recorded the highest polar diameter of bulb, average weight of bulb and marketable yield of onion.
