Sustainable biodiesel production from sunflower is largely dependent on farm input minimization. In that respect, rotation with cover crops is fundamental for yield increase, as well as for controlling soil erosion and degradation, ground water pollution, and maintaining acceptable organic matter levels in the topsoil. A 3year field experiment with sunflower was conducted in Trikala area (Thessaly, central Greece) in the years 2007 through 2009. The study soil was a calcareous sandy loam one. A great importance of crop rotation with cover crop (Pisum sativum) was found on final seed yield in all cases particularly due to the drastic increase of the basic N uptake. The recovery fraction was about 30% for control plots and in case of pisum was fluctuated up to 80%. The sunseed yield fluctuated from 2.5 to 3 t/ha in the control plots depending on the Napplication and from 4.32 to 5.90 t/ha for pisum incorporation, respectively. The NUE was about 18 kg/kg (confirming relevant previous results cited in the literature).
