The research was performed as a randomized full block designwith six treatments and three replications. The treatments were comprised of: full furrowirrigation within whole growing season, alternate furrow irrigation in whole growingseason, full irrigation at the establishment stage and alternate irrigation at the other stages,full irrigation at flowering stage while alternate irrigation at the other stages, fullirrigation at establishment and flowering stage accompanied by alternate irrigation at theother stages, full irrigation at flowering and ripening stages and alternate irrigation inother stages. Overall, the effect of deficit irrigation on yield and yield components wasstatistically significant (p<0.01). Full irrigation in the whole growing season led to thehighest wet forage yield (67022 kg/ha) and while alternate furrow irrigation in the wholegrowing season, the lowest wet forage yield (50064 kg/ha). The most desirable treatmentwas recorded as: full irrigation at the flowering stage and alternate irrigation in the otherstages. With this treatment, the reduction in wet and dry forage yields, leaves wet and dryweights as well as stem wet and dry weights in comparison with control were about 8 to14 %. This is quiet acceptable as it saves 39% irrigation water. The highest irrigationwater use efficiency (1.88 kg/m3) was achieved through full irrigation at flowering stagewith alternate irrigation of the other stages.
