Abstract: The experiment was carried out at Horticultural Research Station, Anantharajupeta, Kadapa district, Andhra Pradesh during 2015-16 and 2016-17 with the application of plant elicitors i.e different concentrations of salicylic acid (50 ppm, 100 ppm, 150 ppm), jasmonic acid (50 µM, 100 µM, 150 µM) once at 45 Days After planting and twice at 45 Days After Planting and 120 Days After Planting and control (no spray). The influence of plant elicitors was also found on fruit quality parameters at the time of harvest. T9 (S.A @ 150 ppm at 45 DAT and 120 DAT) recorded significantly highest T.S.S (12.39 oBrix), total sugars (9.94%), reducing sugars (6.12%), non reducing sugars (3.97%) and sugar acid ratio (49.76) which were found at par with T8 S.A @ 100 ppm at 45 DAT and 120 DAT (12.28 oBrix, 9.89%, 6.1%, 3.97% and 48.83) and T7 (S.A @ 50 ppm at 45 DAT and 120 DAT) (12.21 oBrix, 9.77%, 6.01%, 3.81% and 46.51). The lowest values in this regard were recorded in T13 (control) (10.65 oBrix, 8.31%, 5.32%, 3.31% and 29.71). The lowest titrable acidity was recorded with T9 (0.2) which was at par with T8 (0.2) and T7 (0.21). T9 which was at par with T8 and T3 recorded significantly highest carotenoid content (1.88, 1.87 and 1.79) and the lowest carotenoid content was recorded in control (T13) (1.35). Highest weight of fruits per plant (49.78 kg), yield per plot (552.42kg) and yield per hectare (116.06 tons) were found in T9 which was at par with T8 (47.17 kg, 546.59 kg and 114.83 tons ha-1) respectively.
