Abstract
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.
