Moringa (Moringa oleifera Lam.) is a tree species with known value for food, medicine and water treatment. This study was conducted to: 1) evaluate promising moringa accessions from the World Vegetable Center; 2) select accessions adapted to growing conditions in central Vietnam; and 3) determine the influence of soil types, plant density and pruning height on biomass yield of moringa. The results showed that moringa accession VI08718 is the most adapted for growing in central Vietnam. It gained the highest yield (96.1 g plant-1) and highest mean number of branches at each harvest (3.9 branches). Moringa can grow in any soil type but it gained highest yield in alluvial soil (108.0 g plant-1). Biomass yield of moringa grown in sandy soil and fallow sandy soil was lower than in other soil types. However, improvement of sandy soil and fallow sandy soil resulted in high biomass yield comparable to yield in alluvial soil. Plant density of 160,000 plants ha-1 produced the highest yield (8.3 kg plot-1), whereas plants pruned at 55 cm from the soil surface obtained the highest yield (10.3 kg 
plot-1).
