The study was carried out in Farmer’s field at Basur village, Sorab taluk, Shivamogga dist, during the year 2018-2019. The experiment was laid out in randomized complete block design with three replication and eleven treatments. Results of this study reveal that the combined application of T7 - K2SO4at 1% + Borax at 0.25% + ZnSO4at 0.25% recorded significantly maximum yield and yield attributing parameters i.e.fruit length (27.20cm),fruit diameter (16.17cm), fruit weight (2438g and 2.43kg), number of fruits per plant (49.67), yield plant-1 (90.07kg) and yield (224.96 t ha-1), pulp weight(2343.74g), peel weight(54.98g), seed weight(52.70g) and quality characters like total soluble solids (13.52 obrix), ascorbic acid (54.42mg 100g-1), total sugar (5.64%), reducing sugar (4.60%) and minimum acidity (0.13%)over control and which was on par with T8 (K2SO4 at 2% + Borax at 0.25% + ZnSO4 at 0.25%) and non-reducing sugar was found to be statistically non-significant among the different treatments. The results revealed that the plants treated with T7 - K2SO4 at 1% + Borax at 0.25% + ZnSO4 at 0.25% were found to be effective to improve the yield and quality of papaya cv. Red Lady.
