Effect of Different Organic Manures on the Growth and Yield of Water melon (Citrullus Ianatus)

Field experimental trials were carried out at Federal College of Forestry Mechanization, Afaka. Kaduna located between latitude 100 35”N and longitude 07°21”E at altitude 644m above sea level to compare the effect of different application of organic manures on growth and yield of water melon (Citrullus Ianatus). Two trials were conducted between the early onset of rain in April and post monsoon in October 2011 and the mean of the two trials were taken. The treatments were poultry manure, mixture of poultry manure plus goat/ sheep manure, goat/ sheep manure and control(no manure). The treatments were replicated four times in randomized complete block design. Data were collected on growth parameters such as plant vines length, Number of branches per plant, number of leaves and yield parameters like fruits weight, fruits diameter and number of fruits. The data were subjected to analysis of variance and the mean separated using Least Significant Difference. The results showed that there were significant differences (P<0.05) in plant vine length. The plots treated with poultry droppings had the highest value of plant vine length of 8.20, 137.90 and 216.30 cm at 2, 4 and 6 weeks after planting. Poultry droppings also gave the highest values for the weight of fruit (10.72 Kg) and diameter of fruit (53.25 mm). The best treatment is poultry manure which has the highest yield of 34.25% at 2.5 tonnes per hectare. Poultry manure showed positive effect on all the growth and yield parameters of water melon (Citrullus lanatus) measured. The use of poultry manure is therefore recommended for farmers in the study area in order to be able to obtain good yield of water melon.
