Economic Information Bulletin Number 222. 33 pages., This report detailed how cover crops are managed on corn, cotton, soybean, and wheat fields in the United States. "These surveys reveal that there are many different approaches to using cover crops."
An analysis of secondary data from the National Panel Survey in Tanzania revealed physical, socioeconomic, and institutional factors influencing the adoption of soil conservation technologies among small-scale maize farmers. Findings revealed, for example, only 13.9 percent of those had adopted soil conservation technology. This was cited as small, compared with other countries.
8 pages., This study ascertained factors influencing adoption of improved maize seed varieties in three local government areas of Kaduna State, North-central Nigeria. It collected cross-sectional data for a sample of 180 randomly selected farming households across three local government areas of the State in 2015/16. Both descriptive and inferential analyses were performed on the data. The descriptive statistics differentiated adopters from non-adopters, while the inferential analysis involved estimation of a logit model to determine factors driving adoption of improved maize seed varieties in the study areas. The results of the descriptive analysis show significant mean differences between adopters and non-adopters regarding several farm households’ characteristics. The model results reveal that adoption of improved maize seed varieties among the households was positively influenced by age, household size, level of education, farming experience, labour availability, contacts with extension agents, farm size, off-farm income and membership of associations. Thus, the study concluded that improving farmers’ education, expanding coverage and depth of extension services and strengthening farmer associations are useful policy actions for promoting adoption of improved maize varieties. It is also important to address availability, accessibility and affordability issues constraining adoption, enhance credit access and mitigate risk perceptions. The link between researchers and innovators and the farmers who are the off-takers of their outputs should be reinforced to increase maize productivity in order to satisfy national demand and promote food security.
26 pages., via online journal., This paper employs the patent data of four major genetically modified (GM) crops, soybeans, cotton, maize and rapeseed, to illustratee how the innovation of GM crop technology diffused and distributed globally over time. Data collected from the Derwent Innovation Index, were employed to construct country patent citation networks, from 1984 to 2015, and the results revealed that developed countries were early adopters, and the primary actors in the innovation of GM crop technology. Only seven developing countries appeared in the country citation network. Most developed countries were reluctant to apply GM crop technology for commercial cultivation. Private businesses stood out in the patent citation network. The early adoption and better performance of developed countries can be explained by the activities of large established private companies.
35 pages, We use data from a randomised experiment in Uganda to examine effects of incentives
on the decision to adopt drought-tolerant maize varieties (DTMVs) and mechanisms
through which effects occur. We find that social recognition (SR) incentives to a
random subset of trained farmers – disseminating farmers (DFs) – increase knowledge
transmission from DFs to their co-villagers and change information networks of both
DFs and their neighbours. SR also increases DFs’ likelihood of adopting DTMVs.
However, the corresponding results for private material rewards are not conclusively
strong. We find no evidence that incentives for knowledge diffusion increase the
likelihood of co-villagers adopting DTMVs
