A Meta-Analysis of Maize and Wheat Yields in Low-Input vs. Conventional and Organic Systems - Hossard &al (2016) - Agronomy J

Organic and low-input systems are proposed as ways to reduce the environmental impacts of agriculture. Previous studies have shown that yields of organic systems can be ∼19 to 25% lower than conventional systems. An intermediary, low-input system could be less damaging for the environment than conventional systems, while reducing yield losses in comparison with organic systems. 

In this study, we performed a meta-analysis to compare low-input systems to conventional and organic systems. Our analysis is based on data of cropping system experiments conducted in Europe and North America, and focuses on two important crops, maize and soft winter wheat. 

Pesticide use was greatly reduced for low-input systems as compared with conventional for the two crops (50% for maize, 70% for wheat on average). Mean mineral N use was also reduced by 36% for maize and 28% for wheat in low-input relative to conventional. 

Maize yields in low-input systems were not different from those in conventional systems, and were higher than yields in organic systems (yield ratio of low-input vs. organic = 1.24). Wheat yields in low-input systems were lower than yields in conventional systems (yield ratio of low-input vs. conventional = 0.88), but were substantially higher than yields in organic systems (yield ratio of low input vs. organic = 1.43). 

This is one of the first meta-analyses to assess performance in terms of pesticide use intensity, and yields, with clear evidence emerging that low-input systems can markedly reduce pesticide application, without strongly reducing crop yields.

Alexander J. Stein's curator insight, May 3, 5:08 PM
Input-use in conventional agriculture can be optimised (reduced) following the evidence, while organic farming that completely renounces certain inputs (following ideology) suffers serious yield penalties (and is therefore inefficient and potentially unsustainable).

The Sainsbury Lab's curator insight, April 26, 4:45 AM
Asian soybean rust (ASR), caused by the fungus Phakopsora pachyrhizi, is one of the most economically important crop diseases, but is only treatable with fungicides, which are becoming less effective owing to the emergence of fungicide resistance. There are no commercial soybean cultivars with durable resistance to P. pachyrhizi, and although soybean resistance loci have been mapped, no resistance genes have been cloned. We report the cloning of a P. pachyrhizi resistance gene CcRpp1 (Cajanus cajan Resistance against Phakopsora pachyrhizi 1) from pigeonpea (Cajanus cajan) and show that CcRpp1 confers full resistance to P. pachyrhizi in soybean. Our findings show that legume species related to soybean such as pigeonpea, cowpea, common bean and others could provide a valuable and diverse pool of resistance traits for crop improvement.

4 Edible Insects That Are Delicacies Around the World | Agricultural Biodiversity | Scoop.it
In most cases, seeing a bug on your plate at a restaurant will prompt a return of the plate, a refund and a one-star review of the establishment. Yes, there's nothing wrong with that — your carbonara would be much better without the ants — but there are cultures around the world where eating insects isn't frowned upon. Rather, it's a delicacy. 

And there are a lot of options to go through —  1,900 documented insect species are deemed edible. They might not be a staple in most American diets, but there are some nutritional properties that could make at least some bugs enticing enough to try.

Big Seed: How The Industry Turned From Small-Town Firms To Global Giants

Big Seed: How The Industry Turned From Small-Town Firms To Global Giants | Agricultural Biodiversity | Scoop.it

"Most food, if we trace it back far enough, began as a seed. And the business of supplying those seeds to farmers has been transformed over the past half-century. Small-town companies have given way to global giants. A new round of industry consolidation is now underway. Multibillion-dollar mergers are in progress, or under discussion, that could put more than half of global seed sales in the hands of three companies."

Zack Zeplin's curator insight, April 24, 5:16 PM
The seed industry, one of the largest industries in modern agribusiness, is quickly being swallowed up by the global giants that lead the seed industry. All over the world small seed businesses are being bought out by larger businesses who seek to mass produce their own genetically modified seeds and strengthen their grip on the global seed market. In American agriculture seed giants rule by providing the highest quality seeds to grow the cereal grains in the U.S. produces. But as a result the consumer benefits, farmers can now run farms that aren’t as capital-intensive because of the biotechnology that goes into these seeds. However it is also important to realize that the number of seed companies is dwindling, and that there are only a few large corporations that control all of the seeds that the world needs to grow enough food to survive. I found this article to be very helpful in shedding some light on how the seeds that go into our food is handled, and the truth on how modern agriculture is run.
