Effect of Nitrogen Fertilizer (Urea) Rate Application on Growth Performance of Potato (Solanum Tuberosum L.) on Vertisols of Central Highland of North Shewa, Ethiopia
A study was conducted to determine response of potato (Solanum Tuberosum L.) to different rates of nitrogen fertilizer (urea) applied as 0 kg/ha, 81 kg/ha 165 kg/ha and 246 kg/ha on vertisols of Debre Berhan university demonstration site which was located at central highlands(North Shewa) of Ethiopia. Treatments were arranged in RCBD design. Data was collected after 50% of plants were produced flower in which it was sampled randomly from center of plot. Application of Nitrogen Fertilizer urea 246kg/ha and 165kg/ha delayed days to flowering, increases stem length, above ground biomass, underground biomass, branch number, and stem number as compared to the control(N=0kg/ha). It was observed that application of 165 kg urea/ha is required for optimum growth and performance of potato Gorebeilla variety on Vertisols of Debre Berhan in central high lands of Ethiopia.
