This search was carried out at Tizen Station, Hama Agriculture Research Center, during 2011 and 2012 seasons. The aim of this study is to improve water efficiency and to determine the critical stage for peanut under different levels of irrigation and to study the effect of irrigation levels on yield. Complete randomized block design with four replicates was used. Four treatments of irrigation were applied, the first level (A 100%) was applied when the soil humidity was 75 % of field capacity. At the second level (B) the irrigation was done at 75 % of level A, while at the level C the irrigation was done at 50% of level A, and at the level D the irrigation was done at 25 % of level A. Drip irrigation was used and the irrigation control depended on the differences  of soil moisture by using Neutron Brobe. The values of ETO were calculated depending on meteo data of climatic station. The results indicated that the level A was superior to other levels in yield (3.643 ton/ha), but the best level in water efficiency and yield was level B (0.72 kg/m3, and 2.153 ton/ha), also the water requirement of this level was 2639 m3/ha.

Key words: Peanut, Drip irrigation, KC, Water deficit.

This research was conducted at Al-Kabir Alshamali basin in Lattakia Governorate, this area in located between Syrian-Turkish border, and the Syrian coastal strip within an area of 835 km2, to evaluate the current status of water resources of the agricultural sector, and suggest future scenarios to reduce water deficit using MABIA and WEAP 21. Water evaluation and planning depended on the data from the Directorate of Water Resources in Lattakia, including: river flow, storage capacity, monthly storage, volume curve of dam’s lakes (Tishreen, AlHaffa and AlThoura), evaporation, and losses to ground water in addition to springs monthly flow of and groundwater recharge, besides the data of climatic factors from General Directorate of Meteorology, data of the Ministry of Agriculture (land use including irrigated areas and cultivated crops) and data from the General Commission for Scientific Agricultural Research (mechanical and chemical soil analysis) to calculate the basic moisture parameters. The previous mentioned data were interred for the base year 2011. The results showed that improving irrigation cannels reduced water deficit from 4.2 million m3 in the year 2011 to 2.8 million m3 by the year 2050. While when field Irrigation efficiency scenario is applied, water deficit was reduced to reach 2.2 M.m3 in the year 2050. But when the two previous scenarios are combined, the water deficit which is expected to decrease to 2.1 M.m3 by the year 2050. While when water harvest scenario is applied water deficit will be reduced to reach 1.5 M.m3 by the year 2015. From the above, the importance of applying mathematical modeling using water planning and assessment MABIA and WEAP 21.
