Abstract

In the Fruit Orchard of Guru Kashi University, Talwandi sabo, in the Southern-Western region of Punjab, the current study, named "Effect of foliar spray of Zinc and Manganese on vegetative development, yield, and fruit quality of Kinnow mandarin"(Citrus reticulate), was carried out from 2023 to 24, Applying a mixture of manganese and zinc sulfate to Kinnow plants that are five years old. The study employed a randomized block design with three replications. The inquiry involved the use of various treatments. T4-Zn+Mn (0.5%+0.25%), T5-Zn+ Mn (0.5%+0.35%), T6-Zn+ Mn (0.5%+0.45%), T7-Mn+ Zn (0.35%+0.4%), and T8-Mn+ Zn (0.35%+0.6%) are the groups that comprise T1-control, T2-zinc 0.5%, and T3-Mn 0.35%.The results showed that the best combinations for plant growth metrics, such as plant height (302 cm), mean fruit weight (182 gm), mean fruit length (7.26 cm), and mean fruit weight, were T8: 0.35%Mn+0.6%Zn and T5:0.5%Zn+0.35%Mn. diameter (9.20 cm), average fruit output per plant (482), and quality characteristics with the T5:0.5% Zn+0.35% Mn and T1 control, such as total soluble solid (11.16 Brix) and maximum acidity (1.94).The ideal concentrations of zinc sulfate (0.6% and manganese sulfate (0.35%) to boost output, enhance fruit quality, and promote kinnow vegetative growth.
