Yams

CPC v2.1 Code: 0154

About yams

cpc code 0154 covers the production and trade of yams, a starchy tuber crop that is a staple food in many parts of the world. Yams are an important agricultural commodity, particularly in developing countries, where they serve as a key source of calories, vitamins, and minerals. The global yam industry plays a significant role in food security and the livelihoods of millions of smallholder farmers.

Production process

Yam production typically involves several key steps. First, farmers prepare the soil by plowing and creating mounds or ridges to facilitate drainage and aeration. They then plant the yam tubers, often using a portion of the previous year's harvest as seed. As the plants grow, farmers may mound soil around the base to encourage the development of additional tubers. Harvesting is done manually, with workers carefully digging up the tubers to avoid damage.

Production inputs

The main inputs required for yam production include fertile soil, water for irrigation, and planting material (yam tubers). Farmers may also use fertilizers, pesticides, and other agricultural inputs to enhance yields. Specialized equipment such as hoes, shovels, and yam harvesters are essential for the various stages of production.

Production outputs

The primary output of the yam industry is the yam tuber itself, which can be consumed fresh, processed into various food products, or used as animal feed. Yams are often traded internationally, with major exporters including 0154 Yams and 0154 Yams. The yam industry also generates byproducts, such as yam leaves and vines, which can be used for animal fodder or as a source of organic matter for soil improvement.
