Bananas, Willow for Electricity, Environment Post-Brexit, Block Calving

British scientists are asked to find out if Britain's favourite fruit - the banana - can survive the threat from Panama Disease.
In Cumbria there's a new market for willow. A large paper mill is contracting farmers directly to grow a 'shrub' species of willow as an energy crop.
MPs have been taking evidence on how we should protect the environment post-Brexit.
New research from the Agricultural and Horticultural Development Board suggests as much as £3.5 million a week could be saved across the industry, if farmers moved from year-round calving to block calving - which is when it all happens within a few weeks in either spring or autumn.
