Due to the hot and dry climates of South Khorasan province, choosing the suitable crop and planting date is very important. In this condition, pearl millet nutrifeed hybrid (Pennisetum americanum var. nutrifeed) can be valuable forage in rotation with other plants. This experiment was carried out in 2017-2018 in strip split plots design in time in Azad university research field, Birjand. The treatments were including 4 sowing dates (8 April, 28 April, 18 May and 7 June), 3 irrigation regime (providing 100, 75 and 50 percent of the plant water needs based on the plant potential evatranspiration) and two cuttings in a completely random blocks design with three replications. The highest water use efficiency was observed in providing 50% of water needs and the 8 April along with the first and second cuttings. With the delay in planting date from 8 April to 7 June, the forage dry matter yield of millet decreased by 24.4% in supplying 100% of water needs. This decrease was 24.2 and 46.9, respectively, in supplying 75 and 50% of water needs. Therefore, by supplying 75% of pearl millet water needs and planting date of 8 April, with a 25% reserve of water consumption the dry matter yield is acceptable.
