Effect of different irrigation and fertigation levels on fruit quality parameters in sweet orange (Citrus sinensis L. Osbeck) cv. Phule Mosambi

Abstract

Water and nutrient use efficiency are primary requirements for optimum and sustained citrus productivity. The interactive effect of irrigation and fertigation levels on fruit quality parameters of 10-year-old sweet orange (Citrus sinensis L. Osbeck) cv. Phule Mosambi was studied in factorial randomized block design with nine treatment combinations and control with surface irrigation and band placement of conventional fertilizers. The interaction effects in the treatment T1 (I1F1) i.e. irrigation level I1-100% etc. through drip along with fertigation level F1-100% RD through WSF recorded significantly the maximum juice, optimum TSS, higher ascorbic acid, reducing sugars, non-reducing sugars, total sugars and A grade fruit yield. There was also a significant influence of T1 (I1F1) on per cent A grade fruit yield.
