This experiment for use of low revenue lands with 4 levels of triple super phosphate (0,20,40,60,kg/ha ) as main plot and 3 levels of hamedanian sainfoin (onobrichys_) seed as sub plot, with 3 replications were conducted in split block design at rainfed conditions on spring and autumn cultivation in 3 times for 4 years. Analyzed results showed that sainfoin seed at rate 35 kg/ha (with pod) had the highest dry matter forage per hectare. In total experiment, second year cultivation had the higher dry matter than other years. Autumn cultivation, with different methods of weed controls, was completely better than spring. Mean while different rates of fertilizer had not significant difference in spring and autumn cultivation, in 3 times, but triple superphosphate (60 kg/ha) in autumn and 20 kg/ha in spring caused, that dry matter forage of sainfoin was rised.
