Abstract:

In Ethiopia, potato ranks first among the major tuber crop in the volume of production and consumption. However, the national average yield is 13.8 tons ha-1, which is very low, due to low soil fertility and poor fertilizer management practices. Field experiment was conducted in 2019/2020 main cropping season at Haramaya University research site. The objectives of the experiment were to assess the influences of integrated use of chicken manure and NPS fertilizers on growth, yield components and to estimate the economically optimum rate of integrated use of combine application of NPS and Chicken manure for potato production. Factorial combinations of four levels of NPS rate (0, 50, 100 and 150 kgha-1) and four levels of Chicken manure (0, 5, 7.5 and 10 tha-1) were laid out in a Randomized Complete Block Design with three replications using potato variety Bubu. 100 kg ha-1 urea was used with NPS (50,100,150).
