Abstract
The field experiment was conducted at the College farm, College of Agriculture, Rajendranagar, Hyderabad during rabi season of 2022 with an objective to assess the impact of nano zinc on the growth, yield and quality of sweet corn in Zinc deficient soil. The experiment included 9 treatments with three forms of Zn fertilizer viz., ZnSO4, Zn EDTA and Nano Zn. The results of the study revealed that foliar application of Zn EDTA at 5 g L-1 recorded significantly highest values for growth, Zn uptake and quality parameters while soil application of ZnSO4 at 25 kg ha-1 was the second best treatment. Foliar application of Nano Zinc was significantly superior to the control; however, it was not comparable to the most effective treatment (T9).
