A split-plot experiment was conducted to study the optimum planting density of Nuomi yam in directional groove shallow cultivation. Nuomi yam was the main local cultivar of Dioscorea. This study is expected to provide valuable instructions of local production. Three different planting densities and shallow groove diameters were designed in the experiment. The results showed that the fresh weight of aerial part per plant, yield and planting profit of Nuomi yam tuber were the highest when the planting density was 12 000 plants/hm 2 and the diameter of shallow growth groove was 11.0 cm, while they were the lowest when the planting density was 22 500 plants/hm 2 and the diameter of shallow growth groove was 7.5 cm. Along with the increase in planting density, the fresh weight of aerial part, tuber, fresh yield, profit and commercial tuber rate of Nuomi yam also decreased. The commercial tuber rate of Nuomi yam of 11.0 cm diameter in shallow growth groove was the highest, while it was the lowest without shallow growth groove. On the contrary, the content of amylopectin and mucin was the highest when there was no shallow groove, and was the lowest when the diameter of shallow groove was 7.5 cm, although there was no significant difference between the two treatments. Therefore, Nuomi yam with the directional cultivation with planting density of 12 000 plants/hm 2 and shallow groove diameter of 11.0 cm showed high yield, good appearance quality, high planting profit and no obvious adverse effect on internal quality.
