This work was conducted at the experimental farm of El-Gemmezah Research Station, Agricultural Research Center (ARC) during three consecutive seasons 2019, 2020 and 2021. to study the effect of planting distances(0.15 × 0.60, 0.30 × 0.60, and 0.60 × 0.60 m.) and fertilizer doses of NPK (0-0-0, 50-17-17, 100-33-33, and 200-66-66 Kg^-fed) on three year transplants of Moringa oleifera biomass. The results indicated that, the highest fresh and dry biomasswere produced by planting distancesof 0.15 × 0.60 m. which received 200-66-66 Kg^-fed NPK. That treatment produced 45.5 and 14 ton/ Feddan/cuts for fresh and dry biomass, during 2021 season 1^st and 2^nd cut respectively.
