The center undertakes activities, including research and development, extension and training, technology dissemination, linkaging and promotional activities. The study established a campus-based demonstration technology showcasing ALIAS to facilitate easy technology diffusion. The objectives of this research were to promote： （1） bio-fertilizers and plant-based pesticides in managing insect pests and diseases of organic vegetables and fruit crops; （2） lotus-tilapia integration as a new modality of farming system in frequently flooded areas; （3） honeybee as pollinators to enhance productivity of organic vegetable and fruit crops; （4） Adlai as intercrop to organic vegetable and fruit crops in support to rice sufficiency; （5） native chicken-coffee integration. The results show that： （1） microbial inoculants and plant-based pesticides are effective in controlling diseases and insect pest, respectively; （2） lotus integration in tilapia production system have no negative effect on the tilapia yield; （3） honeybees as pollinators enhances fruit setting by 42%-68% in different crops; （4） Adlai is a viable intercrop for organic vegetable and fruit crops; （5） native chicken integration was found to be beneficial in terms of soil fertility, insect pest control, natural weeding practices and cultivation in the coffee plantation.展开更多

Genetic diversity denotes the variation within species in the functional units of heredity present in any plant or animal, microbial or other origin of living things. Species diversity encompasses the variety of species--whether wild or domesticated, within a geographical area. This study assesses the economic value of crop productivity biodiversity in Ijebu Ode agricultural zone of Ogun State. The authors proposed a dynamic model of market equilibrium with vertical product differentiation that enabled us to take into account the economic consequences of respondents＇ monthly income and species crop of three different communities. The objectives of the study are to identify the personal and socio-economic characteristics of farmers and determine the importance of biodiversity in the study area using Simpson＇s Index. The result showed that 52.50% were male, majority （32.50%） were within the age range of 31 and 40 years old, 44.17% were married, 62.50% had household size of 6-10, and majority （45.83%） had secondary education while 46.67% had up to 20 years farming experience. In conclusion, the authors find that effective factors play an important role in explaining the support for biodiversity conservation, particularly when people do not have specific knowledge about species; while ecological-scientific considerations appear when people are well-informed.展开更多
