Abstract

The study was conducted to evaluate the impact of foliar application of micronutrient and integrated nutrient sources on the “growth, flowering, and yield” of Marigold cv. Pusa Narangi Gainda in year 2021–2022 in randomised block design (RBD) with three replications. Among the treatments, the highest plant height and spread were observed in plants treated with T2 (100% RDF with foliar spray of 0.5% ZnSO4). The greatest number of branches per plant and maximum total dry matter were recorded under T6 (75% RDF with foliar spray of 0.5% ZnSO4 + 0.5% FeSO4). For flowering parameters, T6 also resulted in the minimum days to first flowering, longest flowering duration, highest number of flowers per plant, maximum flower weight, and maximum petal weight, while the largest flower diameter was found in T2. Regarding yield, the highest flower yield per plant, flower yield per hectare, and seed yield per flower were observed under T6 with the foliar spray of 0.5% ZnSO4 + 0.5% FeSO4. It was concluded that from an economic perspective, treatment T6 was determined to be the most efficient
