Abstract: The present study was conducted to assess the influence of time of soil application of Zinc, Boron and Iron mixture on morpho agronomic characters including quality, shelf life and organoleptic parameters in papaya cv. Red Lady. The micronutrient mixture containing 3gm Boron and 10gm each of Zinc and Iron was applied to soil in twelve different treatments (T1- at planting, T2-first, T3-second, T4-third, T5-fourth, T6-fifth, T7-sixth, T8-seventh, T9-1,3,5,7th, T10-1-3rd, T11-4-6th months after planting and T-12 (control; zero micronutrients/water spray). There was very little differences observed in growth parameters and however, there was positive improvement observed in reproductive, yield, quality, shelf life and organoleptic parameters compare to control. The flowering (104.00 days), fruit set (123.11 days) and fruit harvest (147.10 days) after fruit set significantly earliest in T9 compared to control (110.67, 145.33 and 160.22 days, respectively). The treatment T9 was also the significantly best with respect to fruit weight, fruit width, and yield per plant (1.54kg, 16.20cm, 43.54kg, respectively) compared to control (1.13kg, 12.77cm, 20.70kg, respectively). Further, the plants applied with T9 have shown significantly highest total soluble solids (11.50ËšBrix), highest ascorbic acid (23.03 mg/100g pulp) and lowest acidity (0.087%) compared to control. Further, the highest shelf life (8.00 days), good overall acceptability (7.53 marks), maximum score for texture (7.22), maximum score for taste (7.61), maximum score for colour (7.47) maximum score for flavour (7.48) was observed T9 treated plants. The present study indicated that continuous application of micronutrients from planting to first harvest is very important to obtain good yield, quality, shelf and good organoleptic parameters in papaya cv. Red Lady.
