Abstract The combinated use of N,K and B increased leaf size and yield of lotus roots. The highest yield and profit,5.7t/ha and 15812 yuan/ha,were obtained when 270kg N,120kg K2O and 15kg B per hectare were used together. Deficiency of B,K and less use of N influenced yield greatly. Application of B fertilizer gained maximum profit. One kilogram B fertilizer could increase profit from 720 to 2469 Yuan/ha in the experiments.
