Plum is mostly grown under rainfed conditions. However, in order to produce fruits of good size and better quality, irrigation is essential. Various methods of irrigation are adopted to irrigate plum orchards, but in hill basin, drip irrigation methods are more popular and are widely used and recommended. After fruit setting, the plum trees are irrigated at weekly intervals and six to eight irrigations which are recommended for higher production of quality fruits in Santa Rosa plum.
