The Production of Wheat

In the short term, one factor of the ratio is fixed and can not be maintained, but in the long term all factors will fluctuate and you can maintain the desired ratio at the output level . 40X = f (5L, 4K) 80X = f (10L, 8K) long output The output is doubled when all factor inputs are doubled. This production function is a long-term production function or a proportional proportional production function It is called. ) Production function Long-term operation (constant production) Production function It is a production function whose factor ratio is different from production level.

World wheat production has increased dramatically between 1951 and 1990, but the expansion of wheat seedlings has been a major cause of wheat production increase for a long time (CIMMYT, 1996) (Fig. 1.1). Production volume in 1990 reached a record high of 592 million tons, and since 1986 the production exceeded 500 million tons and the production amount reached 529 million tons. Since 1990, production has been relatively stable. The share of wheat production in high-income countries has declined from about 45% in the early 1950s to about 35% in recent years. Due to policy changes in the crop protection program for soil protection, wheat production increased significantly in high-income countries. Over the past five years, developing countries have produced more than 45% of the world's wheat.

Climate conditions in tropical and subtropical countries do not contribute to wheat production. As a result, these countries are heavily dependent on the import of wheat to provide staple foods for their population (FAO; Byerlee, 1987 1-2). In 1960, FAO (United Nations Food and Agriculture Organization) launched a comprehensive wheat flour program aimed at giving power to developing countries through technology to improve food security in their own country. - Panama's food agriculture is an important project in Panama. It not only explains the majority of the country 's exports (over 50%) but also self - sufficiency agriculture hires as many Panama people who can nourish enough food to support their families (nationalencyclopedia .com). The main crops in Panama are big bananas, one of the biggest exporters.
