Abstract :

An experiment was conducted at Kaltungo L G A. demonstration farm in Gombe state during the 2011 rainy season, to evaluate the effect of NPK fertilizer and spacing levels on growth and yield of Watermelon (Citrillus lanatus L). Three different spacings (1×1, 1×1.5, and 1×2 m) and four levels of N P K fertilizer (0, 100, 150 and 200 kg/ha) were used. All the treatments were set in a randomized complete block design (R C B D) with three replications. Plant height, number of leaves, number of male and female flowers at 50% flowering, number of fruits per plant and weight of fruits at harvest were observed. The result of the experiment shows a significant difference (P=0.05) in plant height and number of leaves. Similarly the result shows significant difference (P=0.05) in number of flowers, number of fruits, weight of fruits (2.96 kg) and yield per hectare (63.6 t) compared to the control. The interaction between the treatments indicate that 150 kg/ha of N P K and a spacing of 1×1.5 m gave the highest number of fruit and yield per hectare. Therefore, based on the result of this findings, it is hereby recommended that the use of 150 kg N P K/ha at a spacing of 1×1.5 m should be adopted by the farmers for profitable watermelon production in the study area.
