Nutritional properties of straw mushrooms grown on plantain leaves, maize husk and waste cotton were investigated. Aim: The aim of this study was to recommend these agro-wastes for mushroom production by farmers instead of relying solely on seasonal wild hunting, and to promote consumption of the mushroom. Method: Ten percent (10%) of the mushrooms spawn was used to inoculate 500 g of each substrate in plastic baskets. Mushrooms were harvested after twenty days of incubation followed by proximate analysis of the fruiting bodies. Results: Results indicated that the fruiting bodies harvested from the substrates varied significantly (P Conclusion: These agro wastes are recommended for production of V. volvacea.展开更多

The production and marketing of vegetables crops are undergoing continuous change globally. This is mainly due to the growing demands of consumers for safe and healthy vegetables, increased urbanisation of societies, and the growth in scale and influence of supermarkets chains. Horticultural science can respond to many of these challenges through research, breeding and innovation that can seek to gain more efficient methods of crop production, refined post-harvest storage and handling methods, newer and higher value vegetable cultivars and demonstration of their health benefits. Vegetable breeding has to address and satisfy the needs of both the consumer and the producer. Innovation in vegetable breeding depends on specific knowledge, the development and application of new technologies, access to genetic resources, and capital to utilise them. The driving force behind this innovation is acquiring or increasing market share. Access to technology, as well as biodiversity, is essential for the development of new vegetable cultivars. A few multinational corporations, whose vast economic power has effectively marginalized the role of public sector breeding as well as local, small/medium-scale seed companies, dominate the global vegetable seed trade. For most vegetable crops, only a few multinational seed corporations are controlling large part of the world market. This situation makes a growing part of the global vegetable supply dependent on a few seed providers. The multinational seed corporations ensued from merging some small or medium vegetable breeding programs to reduce costs. There may be fewer vegetable breeders in the future and growers will rely on seeds with a narrow genetic base. In order to meet future needs of vegetable breeders it is important that educational programs incorporate rapidly changing new technologies with classical content and methods.
