Description |
A field experiment was carried out at Horticultural Research Station, Dr. YSRHU, Anantharajupet, Y.S.R. district, Andhra Pradesh, during 2013-2014 to find out the response of zinc and boron sprays on growth, yield and quality of papaya (Carica papaya L.) cv. Red Lady. The experiment consisted of nine treatments viz., T1-Borax at 0.25%, T2-Borax at 0.50%, T3-ZnSO4 at 0.25%, T4- ZnSO4 at 0.50%, T5- Borax at 0.25% + ZnSO4 at 0.25%, T6- Borax at 0.25% + ZnSO4 at 0.50%, T7- Borax at 0.50% + ZnSO4 at 0.25%, T8- Borax at 0.50% + ZnSO4 at 0.50% and T9-Control. The experiment was laid out in a Randomized Block Design with three replications. The results indicated that significantly higher growth parameters such as plant height (243.33 cm), plant girth (46.20 cm) and number of leaves plant-1 (50.07) at 270 DAP and higher yield components like number of fruits plant-1 (63.53), yield plant-1 (106.73 kg), yield per hectare (240.1 t) were recorded with foliar application of Borax at 0.50% + ZnSO4 at 0.25%. All the levels of zinc and boron did not influence the days to first fruit formation and disease incidence (PRSV), however less number of days were taken to harvest in plants sprayed with Borax at 0.50%. The fruit characters like fruit weight (1.68 kg), fruit length (23.53 cm), fruit girth (44.84 cm), fruit volume (2675.00 cc), weight of fruit pulp (1460.01 g), pulp thickness (3.53 cm), cavity length (20.93 cm), cavity girth (10.93 cm) and cavity index (23.99 %) were found to be higher in the same treatment. Significantly the highest TSS, total sugars and the lowest titrable acidity (0.123 %) was observed in papaya fruits when the plants were treated with Borax at 0.50% + ZnSO4 at 0.50% as foliar spray. Higher shelf life was observed in papaya fruits when the plants were treated with Borax at 0.50% + ZnSO4 at 0.25% as foliar spray. This treatment combination (Borax at 0.50% + ZnSO4 at 0.25%) was superior in terms of maximum gross returns (4, 80,286.8), net returns (3, 43,716.6) and benefit-cost ratio (2.50). |
