Abstract：We evaluated the effect of top dressing at critical watermelon growing stage with organic fertilizer on its yield using a Nmin management technology based on soil profile nutrition regulation. The results shown that all of the organic fertilizer treatments increased yield significantly. The yield(60.7 kg/hm2)was highest with the conventional organic fertilization treatment,and the combined organic fertilizer treatment and combined organic fertilizer plus top dressing treatment took the second place(44.9 kg/hm2 and 43.7 kg/hm2). The Nmin with the conventional fertilization treatment was at a relatively high level varied from 160 kg/hm2 at full vining stage to below 100 kg/hm2 later. The composted chicken manure is the best choice in this tests and the quantity of application should be increased properly.
