    <description descriptionType="Abstract">&lt;p&gt;Potato (Solanum tuberosum L.) is a short season crop that thrives best under&lt;br&gt;
sufficient nutrient supply. However, in Ethiopia the yield of potato is quite low&lt;br&gt;
as it is produced with little or inappropriate rates of fertilizer application.&lt;br&gt;
Therefore, a field experiment was conducted for two seasons (2012 and 2013) at&lt;br&gt;
Kobo substation of Sirinka Agricultural Research Centre to elucidate the&lt;br&gt;
combined effects of cattle manure (CM) and NP fertilizers on growth, yield&lt;br&gt;
components, yield and nutrient uptake of the crop. The treatments consisted of&lt;br&gt;
three rates each of CM (0, 15 and 30 t ha-1), nitrogen (0, 60 and 120 kg N ha-1) and&lt;br&gt;
phosphorus (0, 46 and 92 kg P2O5 ha-1), combined factorially and laid out in&lt;br&gt;
randomized complete block design with three replications. Growth parameters&lt;br&gt;
(growth rate, and leaf area), average tuber weight and marketable and total tuber&lt;br&gt;
yield of potato were significantly (P &amp;le; 0.05) influenced by the interaction effects&lt;br&gt;
of chemical and organic fertilizers. Uptake of N and P were higher with&lt;br&gt;
treatments in which 30 t ha-1 CM was applied combined with 120 kg N and 92 kg&lt;br&gt;
P2O5 ha-1 as compared to the control treatment. Harvest index, total tuber yield,&lt;br&gt;
N uptake and P uptake were significantly increased by 134%, 257%, 2446% and&lt;br&gt;
1186%, respectively, over the control treatment in response to the combined&lt;br&gt;
application of 120 kg N, 92 kg P2O5 ha-1 and 30 t ha-1 CM. In conclusion, the&lt;br&gt;
results revealed that integrated application of chemical and organic fertilizers&lt;br&gt;
could be the best strategy to restore highly depleted soils and to enhance&lt;br&gt;
economical production of potato in Kobo district and similar agroecologies.&lt;/p&gt;</description>
