Yields of 36 tonnes/hectare are considered practical by Ami Ben-Amotz of the Institute of Oceanography in Haifa, who has been farming Algae commercially for over 20 years.
Sugar beet yield per unit area of land is dependent upon a variety of factors. It is determined by: Soil quality Climatic conditions Supply of nutrients and water Genetic potential that a breeder has the power to influence An optimum beet stand of approx.
While average yields of major grains such as rice, wheat and maize have more than doubled since 1960, the use of glyphosate-based herbicides has risen 15-20 fold.
Wheat yields increased 100 to 300% around the world since the 1960s, while a study of 30 models found that yields would decline by 6% for every one degree Celsius increase in temperature.
The average area yield is about 220 kg per hectare annually, with estimated yield of only 90 tons due to its remote access and difficulty for transportation.
More encouragingly, the authors found that crop yields for GMO varieties are more stable year-to-year, and the yield fluctuation rate is less than those of conventional varieties.
Yields were extremely low at this estate in 1997(35 hectoliters per hectare), and the harvest, which began on September 8, did not finish until September 25.
Crop yields fall about 5 percent for every degree of temperature rise, according to the United Nations and the Intergovernmental Panel on Climate Change(IPCC).
The hand-picked vines have to be at least 35 years old(bravo for setting the bar this high), yields must be relatively low, and the wines so labelled must pass a tasting test.
ブッシュは低く、果実は甘く、苦味はなく、平均1,2gの重さ、収量はブッシュ当たり2,5kgです。
The bush is low, the berries are sweet, without bitterness, weighing an average of 1,2 g, yields- up to 2,5 kg per bush.
Yet conversely, there is the possibility that ICT, AI, biotechnology, and other such advances will lead to increases in yields per unit of area over and above anything we have seen before.
One mixed inoculant M5 at 45 kg N/ha, increase grain yield to 11-25%, depended on the locations, and save N fertilizer close to 45 Kg N/ha 100 kg urea.
