الملخص EN

The aim of this research was to Sudy the effect of zeolite, manure and zeolite enriched with manure on the productivity of vetch, cotton, wheat and maize crops.

For this purpose, an experiment was conducted during the seasons of 2009 -2011, at the experimental Nation of the Arab Center for the Studies of Arid Zones and Dry Lands (ACSAD) in Deir Alzoor province (Syria).

The experimental design of the experiment was Split Block Design (SBD) with three replicates using fresh water 0.93 dS/m from Euphrates river and drainage water 3.35 dS/m with four treatments namely zeolite (T1), manure (T2), zeolite enriched with manure (T3) and control (T4) .

The amendments were added at a rate of 10 ton/ha before planting.

The results showed significant differences in the productivity of vetch, cotton, wheat and maize crops in the treatments amended with zeolite (15.67, 3.91, 5.2, 3.43 ton/ha respectively) compared to the control (11.61, 3.46, 4.45, 2.86 ton/ ha respectively), also significant differences in the productivity of cotton and wheat were noticed in the treatments amended with manure (3.85, 5.18 ton/ha respectively ) compared to the control (3.46, 4.45 ton/ha respectively), whereas significant differences in the productivity of wheat and maize were noticed in the treatments amended with zeolite enriched with manure (4.77, 3.05 ton/ha respectively) compared to the control (4.45, 2.68 ton/ha respectively).

Furthermore, results showed that there are no significant differences in the productivity of treatments for all crops when using two qualities of water (fresh and drainage).

This Sudy showed significant differences in the productivity of vetch in the treatments amended with zeolite (15.11, 16.22 ton/ha) compared to the control (12.49, 10.73 ton/ha).

Also, significant differences in the productivity of maize were noticed in the treatments amended with zeolite when using two qualities of water (3.73, 3.12 ton/ha respectively) compared to the control (2.86, 2.49 ton/ha respectively), whereas significant difference was noticed in the treatments amended zeolite enriched with manure and irrigated with fresh water (3.51 ton/ha) compared to the control and treatment amended with manure when using two qualities of water.(0.93 dS/m and 3.35 dS/m).

Soil properties were improved in treatments amended with zeolite and zeolite enriched with manure in comparison with the control (for example the percentage of organic matter and total nitrogen, available phosphorus and potassium were increased and soil pH was decreased).
