Abstract

Field experiment was conducted for two successive years on sweet orange to evaluate the effect of multi-micronutrient on yield and quality attributes of sweet orange grown on Inceptisols of Aurangabad district of Maharashtra, India. The result indicates that the number of fruits per tree increased with the application of balanced dose of NPK along with multi-micronutrient from 426 to 554. Similarly, weight of fruit per tree was ranged from 72.42 kg/tree in control to 143.80 kg/tree in the treatment receiving multi-micronutrients through soil. Productivity was also enhanced from 20.06 to 39.83 t/ha due to application of multi-micronutrients along with recommended NPK. The quality of the fruits in terms of juice, TSS, fruit girth, ascorbic acid content, reducing and non-reducing sugar increased with the application of multi-micronutrient and NPK either applied through soil or fertigation, whereas, acidity of the fruit juice was found highest in untreated control as compared to balance nutrient application.

Key words: Multi-micronutrient, sweet orange, NPK, quality of fruit.
