American Journal of Potato Research, 85(2), 150-158.1099-209X1874-9380https://doi.org/10.1007/s12230-008-9011-9https://link.springer.com/article/10.1007%2Fs12230-008-9043-1http://hdl.handle.net/11452/25221This study compared the effects of common vetch (Vicia sativa L.), faba bean (Vicia faba L.), and winter wheat (Triticum aestivum L.; control) cover crop green manures in combination with four rates of nitrogen (N) on tuber yield and quality of three potato varieties (Marfona, Hermes and Agria) during 2-years (2004-2005). Results over years were combined for final analysis. Above-ground dry matter for common vetch and faba bean green manure crops were 2,300 and 2,587 kg ha-1, respectively. Mean root dry matter yield of faba bean (285 kg ha-1) was higher than common vetch (120 kg ha -1). Nitrogen (N) yields of common vetch and faba bean green manure crops were 49 and 58 kg N ha-1 for above-ground and 2.0 and 5.0 kg N ha-1 for root dry matter, respectively. Averaged over all nitrogen fertilizer rates, potato plants grown in plots following common vetch and faba bean green manure cover crops produced 12.7% and 15.0% more tuber yield ha -1, respectively, compared with plants in the winter wheat plots. Potatoes following green manure legume cover crops produced approximately 36% to 38% higher tuber yields compared with potatoes grown following winter wheat when no nitrogen fertilizer was applied. Differences between tubers yields following cover crops decreased as N rates increased. Results over combined 2-years indicated that the economically optimum N rate (EONR) was an average of 30 kg N ha-1 lower for potato following green manure legume cover crops compared with potato following winter wheat cover crop.eninfo:eu-repo/semantics/closedAccessCommon vetchCommon vetchGreen manure plantsNitrogen ratePotato varietiesTuber dry matter yieldTuber dry matter yieldAgriaSolanum tuberosumTriticum aestivumTuber (truffle)Vicia fabaVicia sativa subsp. nigraAgricultureTuber yieldFaba beanYield responseGrowthLegumeProductivitySystemsWheatArticle0002553905000072-s2.0-50849099801150158852AgronomyMineralization; Potatoes; Solanum Tuberosa L
