ABSTRACT
The nutritional value of aonla (Indian gooseberry) fruits is also influenced by the fertilization process,
soil fertility and sources of nutrition. The recommended dose of fertilizers (RDF) was applied in combination
with biofertilizers viz. Azotobacter, Azospirillum and PSB (100 g/tree each) in the rhizosphere zone of
aonla trees. The fruit quality attributes observed during study were physical characteristics of ripe
fruits viz., size, weight and volume of freshly harvested fruits and the chemical properties of fresh fruits
viz., total soluble solids (TSS), titratable acidity using phenolphthalein as an indicator, total sugar and
ascorbic acid. The statistical analysis for randomized block design was carried out with 11 treatments
and three replications. The maximum fruit weight after application of T10 might be result of greater
mobility of the photosynthates into the developing fruits. The estimation of chemical parameters of
fruit viz., TSS, acidity, total sugar and ascorbic acid after application of different treatments resulted
with highest TSS and sugar in treatment T10 (half dose of NPK, 100 kg FYM with Azotobacter, Azospirillum
and PSB). The physico-chemical parameters of aonla fruits were significantly affected through application
of integrated nutrient management practices consisiting inorganic, organic and biofertilizer sources.
