Effects of Poultry Manure and NPK Fertilizer on Growth and Yield of Garden Eggs (Solanum Melongena) in a Sandy Soil in Ghana

Field experiment was conducted at the experimental field of the Department of Horticulture, KNUST, Kumasi, Ghana to test the effects of poultry manure (PM) and NPK fertilizer on the growth and yield of garden eggs (Solanum melongena) in a sandy soil. There were five treatments with five replications. The experiment was laid in Randomized Complete Block Design. Data were collected on the following crop parameters: Plant height, leaf area index and yield. The parameters increased with increase in the rate of PM application. The mineral fertilizer on sole application did not show any significant improvement in any of the parameters. Poultry manure integrated with NPK fertilizer was found to effectively improve the growth and yield of garden eggs.
