The study was carried out in the farmer’s fields of Bahawalpur during Kharif-2018 and Kharif-2019 to examine the impact of different doses of micronutrients (Zn, Fe and Boron) on the yield and quality of brinjal. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Five different levels of micronutrients were applied. The treatment T5 i.e. (100-60-50)+ Borax (0.2) + ZnSO4 (0.5%)+FeSO4 (0.5%) exhibited maximum plant height, fruit weight, total yield, number of fuits plant-1 and survival percentage except number of leaves plant-1 which were maximum in T4 i.e. (100-60-50)+ ZnSO4 0.5%. Concludingly, growth parameters of all the theree cultivars of egg plant showed maximum performance i.e plant height (88.57, 139.77 and 135.11 cm), fruit weight (213, 284 and 261 g), yield (10.11, 11.98 and 12.39 t ha-1), survival percentage (95.71, 99.63 and 90.23%) and number of fruits per plant (9.81, 8.67 and 8.11) due to T5 in black boy, twinkle star and shamli varieties, respectively. Hence, Borax (0.2) + ZnSO4 (0.5%)+FeSO4 (0.5%) kg ha-1 is recommended as best dose of micronutrient for brinjal.
