Most of all, though, the fair is where farmers go to share strategies — growing sunflowers as a protein crop, for instance, when the corn yield isn't up to snuff because of the wet spring — and where novices and wannabes can learn from the experts.
In contrast to a complex agroforest, 'simple agroforestry systems' can be composed of one tree species, for instance coconut, mixed with one annual crop, for instance maize (De Foresta et al. 2000).
(Biodynamics is a belief in the power of the moon, sun, planets and other cosmic forces to influence crops. For instance, Mr. Macari cultivates his vineyard on "fruit" days according to a biodynamic celestial calendar).
In many developing countries, concerns about safety and ownership of seeds led governments to delay or prohibit cultivation of needed crops: Zambia, for instance, declined shipments of G.M.O.
When Gary Toenniessen proposed that AGRA train 50 new Ph.D.'s to be crop breeders, for instance, Gates representatives asked the Rockefeller Foundation to estimate both the cost of that training and how many farmers could be moved out of poverty from the increased crop yields produced by 50 new breeders.
The company is talking to the US government, looking at the commercial market, and also working on an unmanned version of the vehicle – a drone that could be used for crop dusting, for instance.
Other social protection instruments aim to raise household income and crop production, for instance agricultural input subsidies or input trade fairs, as well as public works projects that construct or maintain physical infrastructure such as rural feeder roads.
Different types of plant may need to be put in the ground at different times, or in different seasons, in order to maximize crop yield, for instance, and we may be able to predict accurately that different patients will respond to different drugs even if the basis for these differences remain unknown.
Take crop tops for instance.
