With corn, the "erect" leaves allow the crop rows to be planted closer together. This generally leads to a greater yield per acre becase more plants can be planted per acre.

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.

What is beej bachao andolan?
The 'Beej Bachao Andolan' [BBA], begun in the late 1980s, is twenty five year old, led by farmer and social activist Vijay Jardhari. The Andolan started in the village Jardhargaon of district Tehri, Uttaranchal, famous for its unique movement to save the traditional seeds of the hills.The 'Beej Bachao Andolan' [Save the Seed Movement or BBA] is not only a crusade to conserve traditional seeds but also to promote agriculture and local tradition.A farmer and social activist, Vijay Jardhari realized that modern agriculture was destroying traditional farming. Crop yields of the high-yielding varieties in the modern agriculture were actually low; soil fertility was declining leading to an increasing dependence on toxic chemicals. Along with other activities of chipco movement, Jardhari formed the BBA to promote traditional agriculture and crop varieties.In the valley of Ramasirain, Uttarkashi district, Farmers were growing a distinctive variety of red rice called chardhan. The rice was nutritious and suited to local requirements and conditions. Farmers also grew indigenous varieties like thapchini, jhumkiya, rikhwa and lal basmati. Agriculture here was untouched by modern practices and good yields were obtained without the use of chemical fertilizers and pesticides. What the farmers here were doing was avoiding monoculture in a method called baranaja [12 grains] that involves the multicropping of a no. Of cereals and legumes. This diversification is security against drought and crop failure. Different crops are harvested at different times of the year and ensure year-round supply of food. This also maintain soil fertility replenishes nitrogen.Today BBA has about 150 varieties of paddy from which 100 different varieties can still be grown. BBA has also collected 170 varieties of rajma. Effective pest control is accomplished by using the leaves of the walnut and neem, and the application of the ash and cow's urine. The use of traditional farming methods and seeds has resulted higher yields, improved health of humans and increased conservation of soil fertility and agro-biodiversity.

Why do farmers increase crop yields?
Higher yields = increased income.
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.

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.

What features make hybrid corn more desirable than its parents?
One of the traits that makes hybrids more desirable to some is that certain hybrids have been bred for their sugar content. Those varieties taste sweet and I believe hold their sugar content longer after being picked. more most traits cultivated are producer oriented rather then consumer oriented though this is slowly changing. you are more likely to find hybrids which grant desiese immunities and higher crop yields the sweeter or more nutrient varieties. zaf.
