Abstract: Field experiments were conducted to evaluate the response of pomelo to different levels of lime (0, 2, 4 and 6 kg/plant) along with irrigation water (500 liters/plant). Application of lime and irrigation had significant effect on fruit yield and other yield contributing characters in both the years. Lime had a positive response on the fruit weight, fruit size and number of fruits/plant. Irrigation during dry season (December to April) reduced premature fruit drop and increased fruit set significantly. Use of 500 liters of irrigation water (50 L/plant/15 days) significantly increased the fruit weight, fruit size and fruits yield than non-irrigated plants. Lime as well as irrigation improved the fruit qualities (like % TSS, colour, juiciness, flavour and taste). The combined application of lime (6 kg/plant and irrigation (500 liters/plant) produced fruit weight, fruit size and number of fruits/plant significantly higher than the control. Higher economic return was observed from the combined effects of lime and irrigation with increasing level.
