Repellant Effect of Urine Insecticides Spray and NPK (15:15:15) Compound Fertilizer Application on the Growth and Yield of watermelon (Citrullu lonatus Thumb)

Abstract

A field study conducted to investigate the Repellent effects urine insecticide spray and NPK(15:15:15) compound fertilizer on the growth and yield of watermelon (Citrullus Lonatus Thumb) in forestry Research Institute of Nigeria, (FRIN) experimental plot at Agbede, Etsako West Local Government Area of Edo State. Four regimes of Urine insecticide spray and four rate of NPK compound fertilizer application were factorially combined and laid out in a completely randomized block design (CRBD) with three replication. Urine insecticide spray and fertilizer application did not affect the period of flowering and poddring significantly (P> 0.05). NPK compound fertilizer application significantly (P< 0.05) increase the number and length of main vines, pod number and yield while Vines insecticide spray significantly (P< 0.05) increase the length of the main virus and yield. In the rate of application, 200kg/ha NPK was optimum and this recommended for watermelon cultivation. Twice spray regimes of urine insecticide was recommended for watermelon cultivation.
