The comparative effect of different methods of irrigation such as, microsprinkler + drip (T1), surface (T2) and surface + drip (T3) was studied on Biometric development of Litchi. Surface and microsprinkler irrigation were applied to Litchi when there was intercrop, however drip irrigation was applied during lean period (no intercrop period). The highest crop canopy, 12.10 m2 was recorded in T 1 and lowest, 10.50 m2, in T2. The maximum girth (29.0 cm), shoot length (49.2 cm) and plant height (288.25 cm) were recorded in T1. The yield of Litchi obtained in T1, T2 and T3 was 374.72, 271.48 and 300.27 kg/ha respectively. The number of fruits, fruit weight and fruit diameter were also maximum in T 1. The significant increase of yield in T1, 38.02% over T2 and 10.60% over T3 and overall better performance of Litchi in T1 was might be due to frequent irrigation, uniform moisture distribution in the soil profile and better utilization of nutrients by the crop for its full growth during intercrop period.
