The series Tasks for Vegetation Science is devoted to a variety of research aspects in vegetation science, pure as wellas applied. Of the applied problems one of the most pressing is to achieve better knowledge and improvement of the pasture vegetation in tropical and subtropical regions. As series editor I was impressed by the sheer volume of useful scientific information concerning pasture plants from East Africa collected during many years by Dr. Boonman and compiled in one manuscript. Dr. Boonman first came to East Africa in 1963 on an overland journey along the river Nile which took him from Alexandria in Egypt to Lake Victoria in Uganda and Kenya and back again. After a brief spell as a cotton agronomist in the Sudan Gezira he joined the grassland research team at Kitale, Kenya in 1966. Improvement ofseed yield oftropical grasses was his principal interest which finally led him into the fieldof breeding grasses. Well-known varieties from his work include Boma & Elmba Rhodesgrass as wellas Clone 13Elephantgrass. In 1979he was recalled to The Netherlands to head a cooperative seedcompany involved in the breeding of grasses and cereals. The author has focused this study on one region, Eastern Africa.Global application of theories runs into conflicts too easily with local types of farming, if not with bare economics. Very few books can be found that describe existing practices and seek local answers by digging deep in the stacks of old, local reports.

This alphabetical guide covers common native and naturalized grasses of California and features over 180 color illustrations to aid identification.

In the tenth book in the Guides for the Prairie Gardener series, lifelong gardeners Janet Melrose and Sheryl Normandeau take on the very prairie subject of grasses. Was ever there a prairie-er subject than grass? Important providers of habitat and food for numerous wildlife species, grasses also serve an integral role in erosion control. For the gardener they can open up a bounty of landscaping options, from the lawn to the pond. In the tenth installment of their popular gardening guide series, lifelong gardeners Janet Melrose and Sheryl Normandeau give you the skinny on everything from sod to sedges and raking to rushes. Following a primer on what exactly defines a grass, Sheryl and Janet take your questions on matters like clumpers vs spreaders, mulching and fertilizers, how to tackle problems like chinch bugs and fairy rings. The pair dedicate a chapter to lawns, providing a wide selection of alternatives to the tried and true commercial lawn species and answer questions on raking, aerating, laying sod, mowing, and dealing with dogs and all the damage they seem hardwired to do. Taking your questions on aquatic grasses, as well as edible species (like wheat, rye, and corn), and finishing up with a hall of fame of the best grasses for your every plan and purpose, the authors are sure to expand your knowledge on this truly homegrown topic!
