Abstract
The field experiment was conducted at Horticulture farm, Rajasthan Agricultural Research Institute, Durgapura (Jaipur-Rajasthan) during 2019-20 and 2020-21. The experiment comprised of 12 treatment combinations consisting of 3 drip irrigation levels (50%, 75% and 100% at PE level) and 4 fertigation levels (100%, 75%, 50% of recommended dose of fertilizers through drip and 100% of RDF as basal dose). The experiment was laid out in factorial Randomized Block design. The experimental results revealed that among different treatment combinations highest fruit quality characters such as TSS (B0), TSS:Acid, reducing sugar (%), total sugar (%) and lowest value for acidity (%) and non-reducing sugar (%) of pomegranate fruit was found under treatment I2F3 (75% irrigation at PE level + 75 % RDF through drip).
