  "abstract": "<p>Potato (Solanum tuberosum L.) is a short season crop that thrives best under<br>\nsufficient nutrient supply. However, in Ethiopia the yield of potato is quite low<br>\nas it is produced with little or inappropriate rates of fertilizer application.<br>\nTherefore, a field experiment was conducted for two seasons (2012 and 2013) at<br>\nKobo substation of Sirinka Agricultural Research Centre to elucidate the<br>\ncombined effects of cattle manure (CM) and NP fertilizers on growth, yield<br>\ncomponents, yield and nutrient uptake of the crop. The treatments consisted of<br>\nthree rates each of CM (0, 15 and 30 t ha-1), nitrogen (0, 60 and 120 kg N ha-1) and<br>\nphosphorus (0, 46 and 92 kg P2O5 ha-1), combined factorially and laid out in<br>\nrandomized complete block design with three replications. Growth parameters<br>\n(growth rate, and leaf area), average tuber weight and marketable and total tuber<br>\nyield of potato were significantly (P &le; 0.05) influenced by the interaction effects<br>\nof chemical and organic fertilizers. Uptake of N and P were higher with<br>\ntreatments in which 30 t ha-1 CM was applied combined with 120 kg N and 92 kg<br>\nP2O5 ha-1 as compared to the control treatment. Harvest index, total tuber yield,<br>\nN uptake and P uptake were significantly increased by 134%, 257%, 2446% and<br>\n1186%, respectively, over the control treatment in response to the combined<br>\napplication of 120 kg N, 92 kg P2O5 ha-1 and 30 t ha-1 CM. In conclusion, the<br>\nresults revealed that integrated application of chemical and organic fertilizers<br>\ncould be the best strategy to restore highly depleted soils and to enhance<br>\neconomical production of potato in Kobo district and similar agroecologies.</p>",
