2.1 Courte description de la Technologie

Définition de la Technologie:

Is the cross slope berrier charactrised by contour bunds, cajanus can, pineapples, farm yard manures and grass mulch in banana production.

2.2 Description détaillée de la Technologie

Description:

The contour band stabilized with cajanus cajan and pineapples in the composite manures and trushline application technology is the digging of a 0.6m wide by 0.6m deep along the demarcated contour line, while two rows of cajanus cajan planted along the band spaced at 0.3m and two rows of pineapples at alternating band spaced at 0.3m. The overall purpose of the technology is to reduce soil erosions while increasing soil water infiltration and retaining soil water moisture. The technology is applied perennial cropland in the sub humid climatic zone on the gentle to moderate slope, loam soils with medium soil depth. The technology is done manually using hand hoes and mattock in a mixed production system, land owned individually not titled while the total cost to implement a technology on 0.2ha in the banana field was calculated to be US$ …..

The purpose is to increase land productivity, improve livelihood as well as improved ecosystem and micro climate. This should be attained by improving water use efficiency, soil fertility inprovement to increase crop productivity and generating incomes.

The establishment procedures require the determination of the slope and demarcation of a contour line using a tool known as A-frame. This is done manually during the rainy season. The digging and excavation of the soils is done at the end of harvesting annual crops (bean and maize) using hand hoes manually. The cajanus cajan seeds are sown in two rows along the band and the next band is planted with two rows of pinepples at 0.3m between rows as well as between plants. The shallow ditch measuring 0.6m by 0.6m is excavated at the centre of four banana stools to collect crop residues to decompose and apply them. Old banana stools are up rooted at the end of rain season while measurements and digging of holes done. The spacing is 3.6m by 3.6m for the planted medium variety. The hole measurements is 0.6m width by 0.6m length by 0.3m depth. The farmyard manures are mixed with top soils and covered in the hole for three months before planting. The planting is done before the onset of rainfalls. The dry grass mulch is applied across the slope with a thickness of 0.15m at the onset of rainfalls.
The maintenance procedures require the remove of sedments at the end of rainseason done manually using spades. The trimming of cajanus cajan and pineapples are done manually during the harvesting season. Desuckering and detrushing of banana plants are done twice after harvesting annual crops while grass mulch followed.
