Abstract: The effects of three concentrations i.e., 0.0%, 0.1% and 0.2% of boron sprayed on guava variety‘Allahabad Safeda’in the form of boric acid were studied in Horticultural Garden, College of Agriculture, Banaras Hindu University, during 1966-1968.Highly significant increase in extension of terminal shoot, number of leaves, leaf area per shoot and significant reduction in leaf chlorosis were recorded under 0.2% and 0.1% respectively. Significant earliness in fruit maturity and increase in yield were recorded with boron spray. The physico-chemical composition of fruits markedly improved but only fruit weight and Vit.‘C’were significantly increased at harvest. The maximum effect was exhibited by 0.1% spray.Chemical analysis for different nutrients reflected the better balance of constituents in the leaves. There was increase in boron content, dry weight, ash and phosphorus with boron spraying and 0.2% spray gave maximum effect. Potassium content was unaffected with boron treatment. Marked reduction in nitrogen and carbohydrate content was recorded and maximum was exhibited under 0.2% spray.
