Abstarct: Drought stress is the most important factor limiting the production of agricultural products. The use of inexpensive compounds such as growth regulators and soil conditioners can reduce the effects of drought stress on crops. In order to investigate the effect of salicylic acid and superabsorbent on the growth and yield of sorghum under dehydration, an experimental split plot plot was performed in a randomized complete block design with 3 replications in Jajarm city. Irrigation regimes (including three levels of 8 days, 12 days and 16 days) in the main plots and a combination of superabsorbent soil application (Includes two levels 1-no superabsorbent application, 2- 100kg superabsorbent application per hectare) and salicylic acid spraying (including two levels 1- no use of acid, 2- consumption of half a milliamlar acid) were factorially placed in subplots. The results showed that 16-day irrigation regime treatment reduced tiller number, stem diameter and height, leaf number and area, relative leaf water content, wet and dry forage yield in the first and second cut, protein and ash percentage compared to 8 and 12 irrigation treatments. He fasted, but dehydration increased proline levels. Application of superabsorbent affected all studied traits, and increased stem height, leaf area, relative leaf water content, wet and dry forage yield in the first cutting by 10.17, 14, 8.15, 17.40 and 12.13 percent, respectively, compared to Non-superabsorbent treatment. Also, The results showed that application of 0.5 mM SA in the 4 to 6 leaf stage had the greatest impact on evaluated traits, so that application of 0.5 mM SA caused an increasing of stem height, leaf area, relative leaf water content, wet and dry forage yield in the first cutting and the percentage of protein and ash by 7.44, 10.96, 5.88, 8.05, 10.90, 6.95, 4.85 percent, respectively, compared to the Non-salicylic acid treatment. In general, it can be stated that although the highest forage yield (54.40 tons per hectare) was obtained from the combination of 8-day irrigation regime with 100 kg / ha of superabsorbent soil and half a mM spraying of salicylic acid. The application of these two substances did not play a significant role in reducing the effects of under-irrigation stress, but, in this experiment, the application of superabsorbent and salicylic acid was able to improve many of the studied traits at the same level of low irrigation.
