NIAB has just produced two publications: the first is an all-new Organic Vegetable Handbook and the second is an Amateur Catalogue Database listing all varieties available to gardeners.

Mike Day, NIAB's Vegetable Specialist, said, "Our new organic book, sponsored jointly by Elsoms Seeds and Bejo Zaden, publishes trials data on 13 outdoor vegetable crops, including potatoes. We've looked at 23 sites over 11 years and also listed varieties available as organic seed, making this an invaluable reference book for anyone considering producing top quality organic vegetables."

"The amateur catalogue database is a valuable asset for those interested in organic growing or amateur gardening. It's based on 33 catalogues and includes over 4,250 varieties," he continued.

"Both publications will be very valuable resources for serious organic growers, gardening clubs, allotment associations or keen individuals," he added.

The Organic Handbook is available from NIAB for £15 (inc p&p) and the amateur catalogue database is available either as a hard copy or on a floppy disc for £25 from the same source.
