Abstract

The investment of saline soils whose areas amount to more than one billion hectares in the world and the application of soil amendments such as organic fertilizers, agricultural gypsum, humic acids and sulfur to improve the soil and increase its fertility, as well as the use of foliar sprays with osmoprotectants, i.e., essential oils, proline, ascorbic acid and silicon dioxide to increase growth and the plants’ tolerance to soil stresses are among the recent trends. In addition, the renewal of non-traditional water management methods (groundwater and saline water), hope to achieve water and food security, as well as the need to think about integrated and sustainable programs for the application of local agriculture in arid and semi-arid environments in order to transfer saline farming techniques, especially in light of climate changes that will negatively affect all parts of the Arab world as a whole in general and Egypt in particular.
Exogenous application of FYM at 30 ton.fed-1 as a soil conditioner, and Pro at 10 mM as a foliar spray improved potato growth, yield photosynthetic activity, antioxidant defense system and plant health assessed as increased phenolic compounds, CAT, and POD, in addition decreased PPO activity under 5.2 dS m-1 stress condition. The improving effect of FYM+Pro treatment was more pronounced under salinity stress followed by FYM+EOs treatment, therefore increasing the tolerance of potato plants to saline soil stress and enhancing their growth and health.
