Conjunctional use of saline and non-saline water for reduce the negative effects of osmotic potential in the plant, has gained much attention. The aim of this study is to compare existing approaches and propose a new approach on how to conjunct saline and non-saline water. To do this, an experiment was performed as a randomized complete block design with six treatments and three replications for sorghum in experiment field of Zabol University within 2012-2013. Treatments include; control treatment (100 % freshwater), one-third of salty, the alternate time, the alternate place and the mixed. The investigated cropping indices were dry weight of stem, leaf and aerial organs of plant, plant height and leaf area index. The results indicated; both treatments the alternate place and one-third of salty, in all characteristics have been measured, after the control treatment had the highest yield, as the leaf dry weight, plant height and leaf area index did not show significant difference (p≤ 0.05) and in leaf dry weight and branch dry weight of the control treatment had the highest yield. These two treatments in salts adjusted at the end of the season left acceptable results. It seems local alternative and one-third of salty treatments with their own unique techniques in using saltwater reduce the negative effects of osmotic potential in the plant and compared to the older method (temporal alternative and), they have an advantage.
