Abstract

 Using of low quality resources of water and soil for food production in developing countries must be considered as option. Therefore, this study has done on the plant forage sorghum in different levels of salinity (2, 5 and 8 ds. m-1) and different irrigation levels (120, 100, 75 and 50% of water requirement) in three stages harvesting forage. Experiment done in the form of factorial split plot in randomized complete block design with 12 treatments and 3 replicates in Sistan region in 2015. The results Analysis of variance showed that interaction of irrigation, salinity and harvest and the effects of each treatment alone, the parameters measured in %1 probability level was significant. The results mean comparison of traits measured showed that with increasing salinity and irrigation water depth decreases, yield decrease. But between treatments perfected irrigation and % 75 crop water requirement significant differences was not observed. Also Between treatments with salt 2 and 5 ds/m significant different in feed production was not observed Showed the effects of harvesting forage yield in the second harvest was better than the first and third harvest. Chlorophyll ratio a to b and percentage of proline increased and percentage of caroteniods, chlorophyll a and b increased with increasing salinity and decreasing irrigation water depth. Thus, according to the results and the lack of water in the region can irrigate the plants with %75 of water and salinity 5 ds. m-1 Without any significant effect on the amount of forage produced and the stored water can be used elsewhere and the best cutting forage for yield and quality is the second harvesting.
