Abstract in English:
EU requires that by 2010 5.65% of diesel fuel must be of vegetable origin. To reduce Italian dependence from imported palm oil, it is necessary to increase national production of vegetable oils: canola (Brassica napus or Brassica napus oleifera) is an interesting possibility. In Italy potential areas are available for the cultivation in relation to adequate rainfalls and mild winters. The large seed losses is the main problem limiting canola diffusion. Its success may depend on research initiatives to reduce some of the obstacles associated with its growing. The study objective is to determine if different cropping heads in direct combining can reduce seed losses. The combine was equipped with two different cutting heads: a common wheat type (type 1) and another, similar to the first, but equipped with vertical cutting devices on both ends of the head (type 2). Tests were conducted in Northern Italy (Piedmont). The losses of seeds were measured with appropriate binders on the ground. Moreover the cross-sectional distribution of the losses is more homogeneous in the modified cutting head respect to the other one: that is due to the presence of the vertical cut- ting devices that donít tear the cultivation during the machine advance.
