The response of salt hardening of Maize seeds to salt stress

In order to study the effect of prime treatment (salt hardening) on maize seeds (variety Ghouta 82) and type of irrigation water on the plant response to salt stress through the effect on the productivity and the plant tissue contents Cl, Na and K. Maize seeds were soaked in Euphrates fresh water (EC:1.03 dS.m-1), or in agricultural drainage water (EC: 5.89 dS.m-1) for (12) hours, the seeds therefore were dried and planted in plots of (15 m2) for each replicate and then irrigated with four different types of water; (100 % Euphrates water, 50% Euph. water + 50% agri. drain. water, 33 % Euph. water + 67 % agri. drain. water, and 100% agri. drain. water) during the growing season. K, Na, and Cl in plants were determinated, 1000 grains weight, and grain yield production were estimated in kg.h-1 for each replicate and treatment. The results showed that, it is possible to have 3 tons of grain / hectare by irrigation with agricultural drainage water, which is acceptable, under semi-arid conditions. Salt hardening of maize seeds increased seed yield by (32.80%), which is considered satisfactory under the experimental conditions.

The Syrian Water Situation – An Analytical Study with Future Prospects

This research aims to shed a light on the current state of the Syrian water resource through studying the present resources and analyzing the demand on them and their availability during the period (1992-2012). This study focues at deriving the future forecast on the development of the demand on these resources in order to better conceptualize their current state. This in turn will lead to concluding a set of results and recommendations that could contribute to improve the state of the water resource in the sense of achieving sustainability and prohibiting its depletion through the efficient and planned usage.

Effects of Irrigation Water Fitness on Some Soil Properties and its Crop Productivity

This experiment was conducted during ١٩٩٦-١٩٩٨ to ivestigate study the effect of using different types of irrigation water on some soil properties and its cotton, corn and wheat productivity under the agroclimatic conditions of Deir Ezzor.
