PROBLEMS OF YAM PRODUCTION IN OUR COMMUNITY
ABSTRACT
Declining productivity of yam in Nigeria highlighted the need for a study to determine both the effect of fertilization on yam (Dioscorea spp.) yield andhe best agronomic management options available for stabilizing yam productivity, via the modeling of yam growth and development. This study addressed the above issues by carrying out a research which analyzed the problem of yam production in Nigeria. A questionnaire was administered to elicit information from respondents in the study area. The data collected from the respondents were analysed using the simple percentage analysis and recommendations were made on the problems highlighted.

INTRODUCTION
BACKGROUND OF THE STUDY
Yams (Dioscorea species of family Dioscoreaceae) constitute a multi-species crop that is important for food, income and socio-cultural practices. The most dominant production and consumption zone for yams in the world is in West and Central Africa. Yam plays important roles in the nutritional, social, cultural, and economic life of the people in the yam belt of Africa. Nutritionally, yam is a major staple providing food for millions of people in the world. It is eaten in different forms as fufu, boiled, fried, and roasted (Aidoo, 2009). In Ghana, yam constitutes about 13% of household food budget in urban centers (Aidoo, Ohene-Yankyera, Marfo and Blaise, 2009). Economically, yam is important in the local commerce in West Africa and accounts for about 32% of farm income (Chukwu and Ikwelle, 2000). The crop serves as a major source of foreign exchange earnings and is used as raw materials for starch industries and pharmaceutical companies (Amanze, Agbo, Eke-Okoro and Njoku, 2011). As the leading exporter of yam in the world, yam exports contribute significant foreign exchange earnings to the Ghanaian economy (Ohene-Yankyera, Aidoo and Ohenewa-Tawiah, 2011).
The entire production, processing and marketing chain of yam offers vast employment opportunities for millions of people. The supply of yam offers prospects for income generation due to the number of people involved and the value attached to it. The marketing system, which affects the prices received by farmers and those paid by buyers, has a profound impact on sustainable food security (FAO, 2003).
