Since 1991 Murphy's sows have increased their yield-the number of piglets they bear every year-from 20.2 to 22, a great leap forward in animal husbandry.
Productivity in agriculture had increased throughout the period of the First World War as American farmers increased their yields with more intense cultivation aided by gasoline-powered tractors.
Although the almond industry disputes this finding, pointing out that the study Mother Jones used to arrive at that figure is about a decade old and that almond growers have since increased their yields, there's no question that almonds -- like many tree nuts -- are a water-intensive crop.
They see the only way forward as increasing their yield with increased use of chemicals.
As the report states: "The Food and Agriculture Organisation (FAO) estimates that if women had access to the same productive resources as men better seeds, fertilisers and fungicides they could increase their yield by 20% to 30%.
Some Southern Paiute bands practiced limited horticulture along the Colorado and Virgin rivers, and some bands of Owens Valley Paiute, Northern Paiute, and Western Shoshone irrigated patches of wild seed plants to increase their yield.
Workers on one paint shift, for example, would adjust the machines to increase their yield — only to foul up the strict quality controls required for all three shifts.
Workers on one paint shift would adjust the machines to increase their yield — only to foul up the strict quality controls required for all three shifts.
One of the avenues being recently explored is the improvement of photosynthetic capacity by installing the C4 photosynthetic pathway into C3 crops like rice to drastically increase their yield.
We found that as little as 30 ppm of boron doping in single-phase HEAs, more specific in an equiatomic FeMnCrCoNi and in a non-equiatomic Fe40Mn40Cr10Co10 (at%), improves dramatically their mechanical properties, increasing their yield strength by more than 100% and ultimate tensile strength by ∼40% at comparable or even better ductility.
