Abstract

An experiment was undertaken during 1993-94 in six years old micronutrient deficient chlorotic sweet orange ev. Sathgudi trees to find out the effect of soil, foliar and soil + foliar application of zinc sulphate, ferrous sulphate and manganese sulphate on yield and quality of fruits. The study revealed that the soil application of 50g/plant each of zinc sulphate, ferrous sulphate and manganese sulphate combined with foliar sprays of 0.5 per cent each of the above nutrients resulted in increased fruit yield, TSS, total sugars. ascorbic acid, juice content. reduced peel content, rind thickness and acidity.

Keywords: Sathgudi, zinc. iron and manganese, TSS, acidity.
