Apr 27, 2007 - Scotland - A field of rapeseed blossoms in the sunshine. Experts have declared that summer in Britain has arrived early with rapeseed plants already in full bloom. The vibrant yellow blossom of rapeseed, or oilseed rape (Brassica napus) has become one of the most popular crops for farmers in the UK because of its versatility and ease of growing. Rapeseed oil can be chemically altered to produce bio-diesel and the UK National Farmers Union predicts that bio-fuel could meet over five percent of the country's fuel needs if given government backing and investment.
