We live in a crazy world. On the one hand we read of a surplus of corn and wheat; a mountain of butter and meat, likewise, on the other we see on our TV screens the specter of starving people. Cassava is increasing in importance, particularly in drier areas, because it is a hardy drought tolerant crop that can give reasonable yields on low fertility soils. It is reproduced from stem cuttings and requires weeding until a canopy is established. The roots can be left in the soil until required. This particular book is about how to manage cassava from selection of planting material to harvest. The handbook covers technical and practical aspect of cassava production practices. The book is intended for use by farmers and Extension training officers. Authors are confident that the insights provided in this handbook will be of great value for those who are willing to join the fight against hunger.

The potato is already an integral part of the global food system. It is the world's number one non-grain food commodity, with production reaching a record 320 million tonnes in 2007. Potato consumption is expanding strongly in developing countries, which now account for more than half of the global harvest and where the potato’s ease of cultivation and high energy content have made it a valuable cash crop for millions of farmers. At the same time, the potato – unlike major cereals – is not a globally traded commodity. Only a fraction of total production enters foreign trade. Potato prices are determined usually by local production costs and not the vagaries of international markets. It is, therefore, a highly recommended food security crop that can help low-income farmers and vulnerable consumers ride out current turmoil in world food supply and demand.

Awareness of mushroom food value has increased and their potential as a commercial crop, grown on agricultural wastes, has been demonstrated. Mushrooms can be grown either on commercial scale using highly sophisticated equipment and mushroom houses, or as a home business using fabricated equipment, low cost materials and agricultural wastes. Mushrooms is a high value cash crop and is also a source of vitamins and minerals. It requires very little growing space and provides for economical utilization of crop residues and animal wastes. It offers opportunity for crop diversification. In nature mushrooms have not only been a source of food for men and other animals but also have played an important role in the cycling of carbon and other elements through the breakdown of lignocellulosic plant residues and animal dang which serve as the substrates for the saprophytic fungi. This book sets out the principles of mushroom production. It covers aspects of mushroom cultivation which a grower needs to know before engaging on this attractive venture.
