2.1 技术简介

技术定义:

Enhancement of sustainable land management by capitalizing on the rapid growth, short gestation nature and multiple benefits of small ruminants kept under zero grazing in a banana based farming system.

2.2 技术的详细说明

说明:

Multiplier banana fertilization is a system where rapid growing small ruminants (preferably dairy goats) of low gestation period are kept under zero grazing within a banana based (Kibanja) farming system and their excrement are used in complementing other fertilization of the banana fields. Dairy goats also improve diet of the rural poor and diversify their income. The animals were initially supported by SLM projects as quick win income generating motivation/incentives to farmer who spent their valuable time in SLM activities of long term benefit realization. In multiplier fertilization, a farmer starts only with a few numbers of animals (as kick start). Usually 2 female dairy goats and one improved male goat (buck) suffice. Goat dung collected from the shed is used to perform selective and on spot application of manure to banana plants. Because of their rapid growth and short gestation nature, goats multiplies and increase in number within few years and at the same time in multiplier terms farmers spread and apply manure to more banana plants. Farmers begin with a small animal shed of usually carrying capacity of 4 to 6 goats and can expand it as goat increases. Goats feed on products cut and carried outside or within the kibanja farm. Animals also feed on domestic residuals (e.g. banana peels), food supplements and water for their maximum performance. Goat dung is collected weekly from the shed and is piled in layers, covered with grass and kept shaded under banana canopies to allow microbial action and minimize nutrient loss through volatilization. Depending on the growth stage of banana, dry manure is applied on sport and selectively after every three months of microbial decay. The numbers of animal increases year after year at the same time farmer benefit from the use/sale of animal product (milk in the short term and meat in the long term) and in multiplier manner continue expanding manure application to other banana plants. Manure from goats contributes in improved banana productivity. Benefits accrued from goats also motivate and induce farmers’ patience in terms of their participation in SLM interventions of long term benefit realization.

Purpose of the Technology: Purposes: improved banana productivity, livelihood diversification, income of the rural poor and soil ecosystem through fertility and organic matter replenishment.

Establishment / maintenance activities and inputs: Establishment activities includes, kick start support of farmers with goats (two dairy goats and an improved buck), construction of the goat shed (100% borne by land user to inculcate self-initiative and ownership) and purchase of working tools (spade, rake, hand hoe).
Recurrent activities largely includes, fetching fodders and feeding the animals (cut and carry products outside or within the kibanja), weekly cleaning of the goat shed and manure collection, manure heaping and grass covering for microbial decay/reducing nutrient volatilization, spreading/cooling, monthly on spot and selective application of manure to banana plants, milking of the animals, disease control/deworming and providing supplements.

Natural / human environment: Multiplier banana manure application is used in kibanja farming system in sub humid tropical highland plateau/plains of 1000 -1500m a.s.l. with annual rainfall between 1000 – 1500mm, moderate soil depth and medium loam textural class.
Is used by small scale land users both men and women individual households. In Kibanja farm, land ownership is largely individual not titled and is acquired through inheritance. Production system is mixed (both for subsistence and commercial).
