Are genetically modified (GM) crops a commercial risk for Africa?
What risks might Africa face if it decided to plant genetically modified (GM) agricultural crops? A rough calculation based on current export profiles for one sampling of eastern and southern African countries suggests that the commercial export risks incurred outside of Africa would be quite small. Most of Africa's exports of goods that might be considered GM currently go to other African ...

The economic impact of transgenic crops in developing countries: a note on the methods
A vast literature has accumulated since crop varieties with transgenic resistance to insects and herbicide tolerance were released to farmers in 1996 and 1997. A comparatively minor segment of this literature consists of studies conducted by agricultural economists to measure the farm-level impact of transgenic crop varieties, the size and distribution of the economic benefits from adopting them ...

Validation of molecular markers associated with net blotch resistance and their utilization in barley breeding
With the advancement of molecular marker technology and computer software, mapping quantitative trait loci (QTL) for complex traits in agricultural crops is frequent; however, exploitation of these QTL in practical breeding programs is limited. Here we report the validation of molecular markers linked to net blotch resistance QTL and their utilization in a barley (Hordeum vulgare L.) breeding ...

Agrobiotechnology choices in developing countries
Today's agrobiotechnology revolution - especially the move toward transgenic or genetically modified (GM) crops - is being researched, commercialised, and (hotly) debated mostly in Europe, the USA, and elsewhere within the rich industrial world. Yet it is in the developing countries where the greatest human and environmental promise - or peril - of this new technology may lie. This paper argues ...

Impact of Bt cotton on farmer livelihoods in South Africa
The economic benefits of Genetically Modified (GM) crops in developing countries have been well documented, but little research has been undertaken to date on the impacts of GM adoption on household livelihoods. The research reported here aimed to assess the livelihood impacts of the adoption of Bt cotton in South Africa., and involved 100 interviews of resource-poor farmers growing Bt cotton in ...

Seasonal changes in the performance of a catch crop for mitigating diffuse agricultural pollution
An in situ technology for mitigating diffuse agricultural pollution using catch crops was developed for simultaneously preventing nitrate groundwater pollution, reducing nitrous oxide (N2O) gas emissions, and removing salts from the topsoil. Seasonal changes in the performance of a catch crop were investigated using lysimeters in a full-scale greenhouse experiment with 50 d cultivation of dent ...

An App that Supports Decision-Making and Planning
Informed decision-making leads to smarter decision-making. As Elston Solberg, Crop Intelligence’s own expert agronomist, has said before—"trust the data so you can crush the agronomy.” The data that our Crop Intelligence app provides and the support that our team offers helps you inform your planning and decision-making—both in-season and before next season. Fertility ...

Corn stover to sustain soil organic carbon further constrains biomass supply
Sustainable aboveground crop biomass harvest estimates for cellulosic ethanol production, to date, have been limited by the need for residue to control erosion. Recently, estimates of the amount of corn (Zea mays L.) stover needed to maintain soil carbon, which is responsible for favorable soil properties, were reported (5.25–12.50 Mg ha–1). These estimates indicate stover needed to maintain soil ...

Scale of biomass production from new woody crops for salinity control in dryland agriculture in Australia
There is scope internationally to utilise surplus and degraded agricultural land for biomass crops that might also be environmentally beneficial. For example, dryland salinity in southern Australian could be ameliorated using profitable woody biomass crops. A model was developed to predict biomass production from such woody crops. At a biomass price of A$35/t (green) and a water use efficiency of ...

How to get seed rates spot on for target market and harvest scheduling
Potato agronomy is complex and requires a lot of planning, monitoring and evaluation throughout the production process. CPM finds out how digital agronomy tool Crop4Sight can help in all three areas as preparation for the 2023 season gathers paceIf you fail to prepare, you prepare to fail – an adage that is very relevant when thinking about potato crop establishment, with half the agronomy done ...

Model forecasts long-term impacts of forest land-use decisions
The drive to develop crops for use as biofuel, continues to raise questions about additional uses of forest land. A cutting edge computer model developed at North Carolina State University offers detailed insight to predict the environmental impact – along with understanding forest ecosystem response to global climate change. “We think the model will help policy makers and forest ...

Quantifying of farmers' acceptance and perception in developing kenaf, Hibiscus cannabinus, industry in Malaysia
Kenaf is a new crop to farmers in Malaysia. Although kenaf has much potential as an alternative raw material to wood fibre, the cultivation is developing at slow pace. This paper aims to gather farmers' acceptance and perceptions on developing kenaf as a new industry. A survey to registered Kenaf farmers was conducted in the East Coast region of Malaysia through structured questionnaires and ...
