Why do yields tend to be low in many less economically developed countries?
These countries often do not have access to the higher yielding crop varieties like the more developed countries do, as well as there are not many trade opportunities for farmers from these countries to make much money from. Thus they are more inclined to produce grain for their famileis rather than for sale purposes.
Why have crop yields increased in the past 50 years?
Better seed geneticsBetter crop protection techniquesImproved soil tilth and fertilityImproved agronomic practicesMore acreage under irrigationEtc.
Is artificial selection used today?
Yes, artificial selection is still actively used today in agriculture to breed crop varieties with desired traits such as higher yields or disease resistance. It is also commonly used in animal breeding to produce livestock with traits like improved meat quality or milk production. Additionally, artificial selection plays a role in selective breeding programs for pets and ornamental plants.
How is polyploidy used in the field of agriculture?
Polyploidy is used in agriculture to develop plants with increased vigor, larger fruit size, and improved disease resistance. This can lead to higher crop yields and better quality produce. Plant breeders utilize polyploidy to create new varieties with desirable traits for commercial cultivation.
How might plant crops improve as a result of agricultural research?
Plant crops might improve through agricultural research by developing new varieties with increased resistance to pests and diseases, higher yields, better nutrient content, and improved tolerance to environmental stresses such as drought or extreme temperatures. Research can also lead to the development of more sustainable farming practices, such as precision agriculture or organic farming methods, which can benefit both the crops and the environment.
Why do farmers increase crop yields?
Higher yields = increased income.
How many bushels per acre of sorghum in Kansas?
In Kansas, sorghum yields typically range from 70 to 100 bushels per acre, depending on factors like weather conditions, soil quality, and farming practices. In some years and under optimal conditions, yields can exceed this average. Farmers often aim for higher yields through improved agricultural techniques and hybrid varieties.
What has the author W L Burlison written?
W. L. Burlison has written: 'Eleven years of soybean investigations' -- subject- s -: Accessible book, Storage, Varieties, Soybean, Field experiments 'Yields of different varieties of corn in Illinois' -- subject- s -: Accessible book, Corn, Varieties
Can you trim potato plants to promote healthier growth and higher yields?
Yes, trimming potato plants can promote healthier growth and higher yields by redirecting energy to the development of tubers rather than foliage.
Why do junk bonds have higher yields than traditional bonds?
Junk bonds are risky investments, but have speculative appeal because they offer much higher yields than safer bonds. Companies that issue junk bonds typically have less-than-stellarcredit ratings , and investors demand these higher yields as compensation for the risk of investing in them. A junk bond issued from a company that manages to turn its performance around for the better and has its credit rating upgraded will generally have a substantial price appreciation.
How do interest rates impact bond yields?
Interest rates and bond yields have an inverse relationship. When interest rates rise, bond yields typically increase as well. This is because new bonds are issued at higher interest rates, making existing bonds with lower yields less attractive. Conversely, when interest rates fall, bond yields tend to decrease as well, as older bonds with higher yields become more desirable in comparison to new bonds with lower rates.
Name two regions in different parts of the world where the green revolution has had a significant impact on crop yields?
Punjab, India: The green revolution in the 1960s significantly increased crop yields through the adoption of high-yielding varieties of wheat and rice, along with modern agricultural practices. Central Valley, California, USA: The green revolution in the 20th century led to increased crop yields in the Central Valley through the introduction of new technologies, irrigation systems, and crop varieties.
Why are yields on treasury bonds lower than on coporate bonds?
Treasury bonds are backed by the US government, considered very low risk, hence offer lower yields. Corporate bonds are issued by companies which carry higher risk thus offer higher yields to attract investors. This risk-return tradeoff explains the yield differential between the two.
What is the importance of statistics in agriculture?
Statistics are used in the scientific study of agriculture as a tool to determine if the differences in variables are real or due to chance. This translates to the farmer to let him know with confidence which varieties are better than other varieties or which fertilizer treatments will give better yields than others.
Why do bond yields rise with inflation?
Bond yields rise with inflation because investors demand higher returns to compensate for the decrease in purchasing power caused by rising prices. This means that as inflation increases, bond yields also increase to maintain the real value of the investment.
How can hand pollination be used to improve cucumber yields?
Hand pollination can be used to improve cucumber yields by manually transferring pollen from the male flower to the female flower, ensuring successful fertilization and fruit development. This method can help increase the number of cucumbers produced, leading to higher yields.
Why do yields tend to be low in many less economically developed countries?
These countries often do not have access to the higher yielding crop varieties like the more developed countries do, as well as there are not many trade opportunities for farmers from these countries to make much money from.
