Abstract

Quantity and water quality is an essential factor in the distribution of plant are species on the Earth's surface. water potential of the country represent a severe limitation of water resources, on the other hand increased production mainly depends on the development of the irrigated land is, resulting in a lower quality of water should be considered as a source of irrigation water and irrigated land in future development plans managerial approach to correct for the continuation of agricultural sustainability and achieving reasonable performance, should be seriously considered. The experimental design was a split-split plot randomized complete block in which at least four different levels of salinity (at levels 0.5, 5, 8 and 11 dS/m) as the main plots, four irrigation as sub (supply 125, 100, 80 and 50% water requirement) and two cultivars of CANOLA (Hyola401 and RGS003) as the sub-sub plots in three replications. The results showed that at all levels of the different treatments, WUE for Hayola, is higher than the RGS, that The results generally show that under limited water conditions and water salinity by using management in irrigation for cultivar of CANOLA, Hayola due to higher WUE for cultivation in the study area has a higher priority. The overall increase in salinity for the two varieties of rapeseed decreased WATER USE EFFICIENCY is relative. With the increase in water consumption compared to about 40 cm Hayola relatively sharp gradient increased the WUE rate as 5.4 (mm-1. Kg.ha-1) it increased the amount of water consumed by em 40 nor more than WUE will not increase but only a gentle slope- Terry will start to decrease. The salinity of water depth increases but should maintain yield in this segment reached the conclusion that the increase in water depth of irrigation WATER USE EFFICIENCY is slightly increased and then economical cost-effective It was not. However, too much salt causes a slight increase in irrigation WATER USE EFFICIENCY is. It is observed that the optimal manner of salty groundwater can be used for land use and the amount of salt water savings in other areas used. Dynamics of learning and recall the specific climatic conditions similar to the study area is.
