In another initiative, farm and forest experts from the Chennai-based MS Swaminathan Research Foundation and the Nairobi-based World Agroforestry Centre have met to discuss cooperation in evergreen-agriculture--a type of conservation farming that integrates nitrogen-fixing trees
with annual crops--which has already become popular in several African countries including Cameroon, Ethiopia, Ghana, Malawi, Niger and Zambia.
The governor selling plans and activities of his government as he intends to go for the same gubernatorial position also advised state ministry of agriculture, animal resources, fisheries and forestry to seriously embark on the tree-planting initiative to improve agricultural productivity in rural areas through planting of indigenous nitrogen-fixing trees
To redress this situation, improved short-term fallows using nitrogen-fixing trees
and shrubs can raise maize yields to about 4 t/ha,' Professor Leakey says.
For the past 10 years he has interplanted half a million high-yielding nitrogen-fixing trees
like albizia (Falcataria moluccana) with multiple tree species--primarily Eucalyptus deglupta, also referred to as Rainbowbark eucalyptus for its striking green and brown striped bark, and Eucalyptus microcorys, Australian tallowbark.
The birds' droppings, along with nitrogen-fixing trees
, enrich the soil in which the coffee plants grow.
