Abstract

Soil salinity is now considered as the frontier area of the Indian agricultural research. In India problem of soil salinity Is causing concern over 8.5 m hectare area and the potential soil salinity hazard is threatening another 27% land area. This problem is more pronounced in Haryana, Uttar Pradesh, Orissa, Gujrat, Punjab, Rajashthan, West Bengal, Maharashtra, Andra Pradesh, Karnataka and Tamil Nadu. Mango is the most important fruit crop of India and it is grown on 1.401 million hectare land with total production of 9.782 million tones. It is more sensitive to soil salinity at younger stage. Northern India is the largest belt of mango cultivation contains appreciable amount of salts due to introduction of canal irrigation. It has now become serious problem for the establishment of new mango orchards. In irrigated areas, salinity is almost a universal threat because irrigation water normally contains hundred or thousands mg salts per liter of irrigation water. Little efforts have been made to study the effect of salts in systematic manner. Emphasis must be given to find out the physiology of salt stress in mango and its impact on the different plant growth functions. There are two-three mango genotypes having some degree of tolerance to salt but studies on the exact mechanism and level of salt tolerance in those mango genotypes still lacking. Identification of salt tolerant rootstocks and performance of scion cultivars on those rootstocks in saline conditions will determine the success and expansion of mango area in salt affected soils.
