Abstract

Field experiment was conducted in KARI, Matuga, Kwale District in the coastal region of Kenya for two seasons to test the response of ‘sugar baby’ watermelon [Citrullus lanatus [Thumb]. Mansf.] to four levels of nitrogen (0,40,80 and 120 kgN/ha). The treatments were laid out in a randomized complete block design with three replications. Nitrogen had positive significant effect on days to flowering, sex expression ratio, number of fruits/plant, fruit weights, firmness, rind thickness, total soluble solids. Application of 80 and 120 kgN/ha increased the fruit sugar content by 23% and 28% compared with zero application. The total fruit yield was highest at 120 kgN/ha and lowest at zero application. For improved growth yield and quality of water melons in the coastal region of Kenya 120 kgN/ha was recommended.
