| Abstract | ||||
| During 2016 and 2017 seasons, five martials namely ABA, Chitosan, Salicylic acid, Mannitol and Selenium each at 100 ppm were tested for their beneficial effects on counteracting the inferior effects of salinity on fruiting of Ewaise mango trees grown under soil and irrigation water salinity (salinity of soil and irrigation water were 4.69 dsm and 3.13 dsm ppm, respectively). The selected trees received three sprays at growth start, just after fruit setting and one month later. Subjecting the trees to the five materials namely ABA, Chitosan, Salicylic acid, Mannitol and Selenium each at 100 ppm was accompanied with enhancing all growth aspects, tree nutritional status, yield and quality parameters relative to the trees grown under salinity stress alone. The best materials, in ascending order, responsible for reducing the adverse effect of salinity were ABA, Mannitol, Salicylic acid, Selenium and Chitosan. For alleviating the unsuitable effects of salinity on fruiting of Ewaise Mango trees grown under soil stress, it is recommended to spray chitosan or selenium each at 100 ppm three times at growth start, just after fruit setting and one month later. | ||||
