The experiment for studying the effects of fertilizer application on the growth and development of honeydew melon was conducted on a number offertilizers are widely used in the market. The results of the experiments show that: (i) basal fertilizing organic Biology of Agriculture and Forestry have a positive impact on the growth and development of honeydew melon plants. Specifically, after 35 days planting, the average height is 113.44 cm, 0.75 cm diameter, the branch at 13 branches, 14.22 dark green leaves. There are 59.61 male flowers a tree, 5.55 female flowers a tree. Fruiting rate is 52.49 percent, a ripe fruit weight is 2.53 kg, quality of fruit is good
(ii) putting by Lam Thao NPK (12:5:10) have the best impact on the growth and development of Honeydew Melon plants. Specifically, after 35 days planting, the average height is 103.06 cm, 0.73 cm diameter, the branch at 15 branches, 13.89 dark green leaves. There are 46.17 male flowers a tree, 4.32 female flowers a tree. Fruiting rate was 52.87 percent, a ripe fruit weight is 2.43 kg, quality of fruit is good.
