Response of Ber to Nutrient Management in Relation to Yield and Physico-chemical Composition of Fruits under Semi-arid Condition

Abstract

A field experiment was conducted on response of nitrogen, phosphorus and zinc nutrition on yield and physico-chemical composition of ber fruits under semi-arid condition of western Rajasthan. The highest fruit yield, dry matter, pulp:stone ratio, TSS, ascorbic acid, reducing sugar, non-reducing sugar, and total sugars were recorded in soil applications of 500 g each of nitrogen and phosphorus and 0.6% zinc sulphate as foliar application. The interaction among nitrogen, phosphorus and zinc was significant with respect to yield, which was maximum (42.12 kg plant-1) under 500 g each of N, P and 0.6% zinc sulphate. Key words: Ber, nitrogen, phosphorus, zinc sulphate, yield, physico-chemical quality parameters.
