Abstract: To get higher production and economical purpose, each crop needs to maintain its fertilizer requirement and plant growth regulators application. Micronutrients play an essential role in the plant metabolic processes that helps to improve growth and quality of onion while growth regulators govern all the factors of development and growth within plants. The field experiments were conducted during the rabi season of 2019 at Main Vegetable Research Centre, Anand Agricultural University following RBD design with 12 treatment including control. to investigate the effect of foliar application of micronutrients and growth regulators on growth, yield and quality attributes during development stage of onion. The application of GA3and micronutrients like Zn, Fe and Si through foliar application significantly improve the growth parameters like plant height, number of leaves, leaf length, dry weight, fresh weight and yield parameters. The result showed that foliar application of Zn (1g/l) +Fe (1g/l) + GA3 (100mg/l) at 30 DATP considered as the best treatment for higher phytochemical quality and yield production under Middle Gujarat agro-climatic condition.
