Allotment tales

I'm also having a go at vegetables in raised beds using the "square foot gardening" method, invented by an American called Mel Bartholomew. There is a website, think it's just "square foot gardening", but google will find it. There is a great logic to it, giving very intensively planted beds, each bed being divided into square feet, so a four foot bed would be divided into 16 mini-beds with a crop in each division. There's also a v.good book (i got it via amazon)which explains it all called "square foot gardening" (there's a surprise!) It all hinges on very good soil/compost in the bed, and good cultivation. there's probably a much easier answer to your question, but I hope this might help. good luck.
