2.1 Short description of the Technology

Definition of the Technology:

Is a cross slope berier characterised with 2m widith by 2m depth furrow, farm yard manures and grass mulch in banana production.

2.2 Detailed description of the Technology

Description:

The level ditches combined with farm trushlines, farm yard manure, and grass mulch technology in banana production is the digging of a furrow measured 2m wide by 2m deep along the contour in the banana plantation. The technology is applied on a perennial cropland by combining structural, vegetative and agronomic measures. The climatic zone is sub humid in a gentle to moderate slope with medium to deep loam clay soils. The hand cultivation is done manual using hand hoes in a mixed production system. The establishment procedures contour demarcation using a local made A-frame, digging a furrow along the contour, digging the banana holes spaced at 3.6m by 3.6m between the structures, mixing farm yard manure with top soils and planting banana suckers after restng the mixture for not less than 60 days. The maintenance procedures requires, weeding the field, desuckering, detrushing, planting beans, topical manure application, grass mulch application and filling the contour furrow with farm trushlines. The land ownership is individual not titled. This technology was introduced in 2012 by Kagera TAMP using the FFS methodology. In case of sensitive climatic extremities

Purpose of the Technology: The major purpose for technology application is reduced moisture stress, increased soil water retention, reduced soil erosion to increase crop productivity in a sustainable land management.

Establishment / maintenance activities and inputs: The establishment activities included; first to clear the field and demarcate the contour line using a local made A-frame done at the end of short rains. Second is to plough and harrow the field done in the early dry season. Third is to space and dig holes for planting banana suckers done in mid of dry season. Fourth is mixing farm yard manures with top soils and cover the hole for not less than sity days before planting, this is done in mid of dry spell. Fourth is to plant certified banana suckers done in late dry season. Fifth is to dig the contour ditch done in at the onset of long rainfall. The maintenance activities includes; first to weed the entire field done twice before the onset of rainfalls. Second is to apply farm yard manures concurrently with grass mulch done once in the late dry period. Third is to desucker and detrush banana plants done twice before planting beans. Fourth is to plant beans done once before the onset of long rainfalls.

Natural / human environment: The natural environment in the location is 750-1000 mm rainfalls, foots lopes valley floors landform, gentle slope, shallow to meium soil depth (50-80)cm and (80-120)cm characterised with two growing periods. The social economic persisting are small scale land users farming on( 0.5 to 2)ha per house hold. The land ownership is individual not titled while the water use rights is open access. The importance of off-farm incomes is less than 10% and the market orientation is mixed while soil cultivation is manual and livestock are not fed on farm residues.
