2.1 技术简介

技术定义:

Is the embanked soils on the lower side of the furrow, lemon grass and vetiver grass strips along the contour lines combined with Farm yard manures and grass mulch application in banana production.

2.2 技术的详细说明

说明:

The slope cross barrier technology in banana production is a 2m deep by 0.6 wide furrow at the less slope combined with lemon grass, vetiver grass contour strips at the greater slopes.. The lemon grasses and vertiver grass are planted in single row spaced 0.3m plant to plant. The distance between strips is about 18m at the slope category of 2%. The technology is applied on the cropland in the tropics, sub humid, dissected plain to flood plains, sandy clay loam over sand clay and deep to moderate deep soils. The land is cultivated manually using hand hoes in a mixed production system. The land ownership is communal and individual not titled. The establishment procedures includes planting of banana suckers, lemon grass, vetiver grass, fruit trees, construction of fanya chini and planting gravelia spps along the boundaries. The maintenance procedures require application of FYM at the rate of 24-36kg per plant. Grass mulch is spread across the slope at the thickness of 0.15m. The average establishment costs is US$ 3,531.42 per hectare while maintenance costs on average is US$ 351.77 per hectare. The technology was introduced fifteen months past ( March 2013) using Demonstration plots methodology. Common agronomic measures such as using improved banana suckers and banana weevils trapping can add extra effectiveness to the main technology.

Purpose of the Technology: The general purpose of the technology is to reduce soil erosion, reduce soil moisture stress and increase soil nutrient cycling and soil organic matters.

Establishment / maintenance activities and inputs: The establishment activities includes first, clearing and cultivation of land in May done manually using machete and hand hoes. Second, harrowing in May done manually using fork handhoes. Third is identification and demarcation of contour lines doneusing A-frame. Fourth is spacing and digging of holes for banana and fruit trees done manually done. Fifth is planting of banana suckers and fruit trees done manually. Sixth is planting of vertiver and lemon grasses along the demarcated contour lines done manually, seventh is digging the farrow and excavating soils to be placed at the lower side of the furrow done manually. The maintenance activities include; first, weeding the entire field using hands done in twice April and October. Second is manure application using plastic buskets done. Third is spreading grass mulch done manually, fourth is desuckering using chisel hand hoes done twice in April and October. Fourth is detrushing using machete and local made tools (rwabyo) done twice (May and January). Last but not least is harvesting of banana, lemon grass and fruits done on market demand.

Natural / human environment: The land ownership is communal and individual not entitled while the water use right is open access. The natural environments are 1184mm of rainfall.The technology is tolerant to drought and seasonal rainfall decrease. Soil fertility is low to moderate. Top soil organic matter is medium, Soil drainage is medium. Soil water storage capacity is medium.
