2 nd AFRICAN ORGANIC CONFERENCE 2012<br />

May 2-4, 2012 in Lusaka, Zambia<br />

resources to support agricultural transformation, Infrastructure Development to support agricultural<br />

transformation and Mobilization.<br />

<strong>The</strong> model focuses on healthy and just farms, food systems, communities and environment by bringing<br />

people together for education, alliance building and advocacy. Collection of specific natural methods,<br />

which when applied to farming, produces results that are in harmony with the environment which include<br />

Land preparation, planting, management of crop growth, weed management, harvesting, storage and<br />

marketing. Soil conservation and management contribute about 60 % of the crop quantity and quality<br />

production. For efficient organic farming, the growers need to know much about soil.<br />

Small holder farmers have doubled food production in a decade by using simple ecological methods and<br />

most efficient farming techniques. Scientific evidence demonstrates that organic methods outperform the<br />

use of chemical fertilizers in boosting food production where the hungry live –especially in unfavorable<br />

environments, headed. Soils productivity and crops protection against pests have greatly improved by<br />

natural environment such as beneficial trees, plants, animals and insects, according to the local studies.<br />

Agro-ecological projects in IRTECO intervention areas have shown an average income increase of 60 per<br />

cent.<br />

Abstract<br />

Several innovations have been made in rice cultivation in order to increase grain yield and[ ]better meet the<br />

world’s food demand. <strong>The</strong> “Green Revolution”[ ]which was one such accomplishment has undoubtedly<br />

contributed to a tremendous yield increase in Asia, where many farmers were able to afford the new<br />

technology. However, it failed to help many farmers in Africa, where farmers are constrained by their<br />

limited financial resources and which is characterized by an immense variability of agro-ecological<br />

conditions. While plant growth and productivity are known to derive from the interaction between genetic<br />

potential (G) and environmental factors (E), efforts to improve rice production have usually focused on<br />

making changes in G, assuming a standard E that is created by conventional rice-growing practices.<br />

Genotypes have been assessed for their performance in continuously-flooded paddy soils, with optimallydense<br />

plant populations, with reliance on inorganic fertilization to raise yields.<br />
