Abstract
A field experiment entitled "Effect of foliar spray of nutrients on yield and quality of Nagpur mandarin (Citrus reticulata Blanco.)" was conducted at the Fruit Instructional Farm, Department of Fruit science, College of Horticulture and Forestry, Jhalawar during May, 2018 to December, 2018. The experiment consisted of 33 treatments having two levels of each, Zinc sulphate (@ 0.25 % and @ 0.5 %), Ferrous sulphate (0.25 % and 0.5 %), Copper sulphate (0.25 % and 0.5 %) and potassium sulphate (0.5 % and 1.0 %). The experiment was laid out in Randomized Block Design with three replications.
Among different foliar doses of treatment combinations of micronutrients and potassium sulphate, T27 treatment consisting (FeSO4 @ 0.25 % + K2SO4 @ 1.0 %) resulted in enhancement in plant height and canopy volume; whereas application of treatment T22 (FeSO4 @ 0.25% + CuSO4 @ 0.25 %) resulted in per cent increase of N-S plant spread of Nagpur mandarin trees.
The results under influence of foliar applications of various treatments reflected that the application of treatment T21 (ZnSO4 @ 0.5% + K2SO4 @ 1.0 %) was found best with regard to augmentation in number of fruits/plant, estimated yield/plant (kg), fruit weight (g), fruit length (cm), fruit breadth (cm), peel thickness (mm), number of segments per fruit, minimum number of seeds/fruit, juice recovery percentage. rag percentage, TSS, minimum acidity per cent, TSS/Acidity ratio, ascorbic acid (mg/100 g), total sugars, reducing sugars, non-reducing sugars and juice pH over other treatments.
