Changes in soil properties as influenced by single and combined application of organic manures, inorganic fertilizers and biofertilizers and their response on yield and quality of sweet orange (Citrus sinensis Osbeck) grown on Udic Haplustert were evaluated through a field experiment during 2002–04. Among soil physical properties, only hydraulic properties of soil significantly influenced both fruit yield as well as quality. The changes in available nutrients in the soil were positively correlated and possibly played a dominant role in regulating the fruit yield. Nutrient concentration in leaves was more significantly correlated with yield and quality parameters than the soil available nutrients, signifying the superiority of leaf over soil analysis.
