Low soil fertility is a major constraint to potato production in Ethiopia. A field experiment was conducted at Rare research farm, main campus of Haramaya University in Ethiopia, during the main growing season of 2011 under supplementary irrigation to evaluate the effects of Jatropha curcas L. press-cake and inorganic NP fertilizers on the productivity of potato (Solanum tuberosum L.) and soil properties. The treatments consisted of four rates of Jatropha press-cake (0, 2, 4 and 6 t ha-1) and five rates of combined mineral N and P (0 + 0; 0 + 46; 50 + 0; 50 + 46; 100 + 92 kg N + P, respectively, ha-1) fertilizers. The experiment was laid out as a randomized complete block design (RCBD) in a factorial arrangement and replicated three times. Well sprouted medium-sized potato tubers of a potato variety named Badhasa were planted on 30 May 2011 at the spacing of 75 cm between rows and 30 cm between plants accommodating approximately 44,444 seed pieces ha-1. The plot sizes were 3.75 m x 3.9 m. The distance between plots and blocks was maintained at 1 and 2 m, respectively.
