ارزیابی مصرف بهینه و کارایی مصرف آب گیاه سیب زمینی در اهواز (Solanum tuberosum L.)

In order to study Evaluation optimum consumption and water use efficiency of potato in Ahvaz, an experiment was carried out in split-split plot using randomized complete block design with three
replication in experimental field of, Department of Agronomy and Plant Breeding, University of Shahid Chamran at Ahvaz, during 2011-2012 cropping season. Experimental factors were included: method of cultivation at two levels: furrow and flat cultivation, method of irrigation at two levels: full furrow irrigation and alternate furrow irrigation and type of cultivar included: Ramus, Santeh, Cosima and Agria. Based on design plan,The Furrows were made in plot before the performance treatments. The results showed That method of furrow cultivation caused significant increase on tuber yield and water use efficiency. method of alternate furrow irrigation by water use efficiency 8.4 kg/m3 was better with full furrow irrigation 4.66 kg/m3. Also, Agria was better in tuber yield 29.86%, and water use efficiency 32.79% compared to other cultivars, whereas with Santeh had not significant difference in tuber yield. Therefore, based on the results, it seems that Agria and Santeh cultivars in the furrow cultivation using alternative irrigation to achieve the appropriate yield and high water use efficiency was suitabel conditions.
