Effect of leaf to fruit ratios on the physico-chemical quality of guava (Psidium guajava L.) cv. pant prabhat planted under high density

Abstract

An experiment was conducted during years 2016-17 and 2017-18 to determine the effect of leaf to fruit ratio on the physico-chemical quality of guava planted under high density. Plants at four spacing namely S1= 1.0 m x 1.0 m, S2= 1.5 m x 1.5 m, S3= 2 m x 1 m and S4= 2 m x 1.5 m were selected and different leaf to fruit ratio treatments of T1=4:1, T2=8:1, T3=12:1, T4=16:1 and T5=Defoliation of fruiting shoots (appx. 24:1) were imposed on them while untreated trees served as T6 = control (appx. 32:1). The results revealed that highest mean fruit weight, fruit length, fruit volume, total soluble solids, reducing sugar and total sugar per cent was recorded in spacing S4. The maximum mean fruit weight, fruit length, fruit volume, total soluble solids and total sugar per cent were recorded in moderate leaf to fruit ratio of T4 and T3.
