A PROPER irrigation of mango orchards is vital to prevent fruit drop and help improve young fruits. Additional irrigation at the ripening stage results in a significant improvement in both fruit size and quality. The success of mango orchards largely depends on method and management of irrigation. Proper irrigation scheduling, especially during the period of plant growth and fruit development, plays vital role in the sustainability of orchard. The objective of irrigation is to apply the required quantity of water as per tree requirement at the right time. The frequency and amount of irrigation need depends on the type of soil, its properties, prevailing climatic conditions, rainfall and distribution, age and size of trees .Mango tree is evergreen grown in tropical and subtropical regions of the world. Due to its superb juicy, tasty and colourful fruit, mango is known as the king of fruits. Mango tree is considered drought resistant to some extent; however soil moisture influences the fruit size, quality as well as the drop of immature fruits. Under hot and dry climate, irrigation prevents drop of immature fruits during fruit development period. It is also observed that moisture deficit in soil results in early maturity to fruits resulting in poor quality. Properly irrigated trees have fruits of better size and juicier than those trees with soil moisture deficit.
