| Abstract | ||
| This study aimed to investigate some possible approaches to alleviate the negative effects of salinity on tomato plant growth and productivity. Seeds of tomato (Lycopersicon esculentum Mill) hybrid VT737 were sown and seedling were exposed to hardening treatments using four levels of saline irrigation (control 250 ppm, low 1500 ppm, medium 3000 ppm and high 4500 ppm) during nursery stage. After transplanting in the open field, all plants were irrigated with saline water with 5500+ 500 ppm and the standard recommended fertilization dose. Plants were also receiving four experimental fertilization treatments namely control (no additional fertilization), mono potassium phosphate, potassium humate and amino acids. Recorded data showed that all vegetative and reproductive parameters responded positively to the individual effect of hardening and fertilization treatments and their interactions. The hardening level of 3000 ppm showed the best effect followed by the 4500 level and the least for 1500pp. Meanwhile the fertilization of mon potassium phosphate gave the best results followed by potassium humate then the amino acids. The interactive effect of the treatments appeared to be cumulative on plant response. | ||
