NORMATIVE FRAMEWORK
TELEFOOD SPECIAL FUND PROJECT FORMAT
"Year-round Vegetable Production in the Humid Tropics"
Target group
Primary beneficiaries will be the poor smallholder farm families involved
with crop diversification away from volatile commodity production, by
encouraging the increased efficiency of utilization of their limited plots
of land through extension of the production season.
Background and justification
In the humid tropics, farmers may be intensively involved in the production
of such crops as coffee, green pepper, sugarcane and rice. However, due
to the uncertainty of returns generated from these traditional cash crops
caused by fluctuation in commodity prices, many of them have initiated
small-scale vegetable growing. This initiative has rapidly proven to be
rewarding because the vegetables fetch high prices, not only for consumption
locally, but also for export elsewhere in the country. Unfortunately,
production is generally limited to the dry season. Production in the rainy
season is hampered by flooding leading to waterlogged soil conditions,
rapid weed growth leading to high weed populations and resulting competitive
losses to the crop plants, physical damage to plants and high pest and
disease incidence.
Pre-requisites
A number of pre-requisites need to be satisfied before project assistance
should be considered, specifically:
- a local willingness to participate in and contribute to the programme
both at governmental ad community level;
- an institution (government or NGO) capable of initiating and supervising
the programme in the project area, as well as providing other essential
inputs not covered by TeleFood;
- Advisors/extension staff trained in horticulture, preferably with
experience in vegetable production and marketing, and with a good understanding
of the local cultural environment and farming system practices.
Objectives
The primary aim of the project is to expand production of vegetables throughout
the entire calendar by introduction of low cost, simple and adapted protective
structures, appropriate crops and cultivars adapted to the hot and humid
wet season conditions, and use of cultural practices for water management.
The project will concentrate on assisting small farmers to acquire the
related technology to enable them to produce vegetables all year round,
and provide a sustainable income generation security for twelve months
of the year.
Duration of the project: Typically one year.
Outputs
The principle benefit will be the increased production of vegetables by
the extension of the growing and production season. This will be multiplied
by the use of improved production practices and the yield increase that
can be expected from use of specifically adapted crops and cultivars for
the differing production seasons. The availability of irrigation supplies
for continuous irrigation, even during specific periods of the wet season,
will reduce crop losses, and, depending on an irrigation source being
available, will increase the range and amount of vegetable production
during the dry season.
The technology involved in this programme is simple and easily replicated
and can be expected to be readily adopted once the initial pilot programme
has successfully demonstrated the benefits accruing to the participants
for off season vegetable production.
Activities
The basis for interventions will be improved crop husbandry, through provision
of shelter from the rainy season excessive rainfall for especially sensitive
crops; use of appropriate crops and cultivars to extend the current season
of production in the open; water management through removal of excess
during the rainy season, and provision of simple water storage and delivery
systems for the dry season. The main areas of activity that the project
should undertake are:
- Design and construction from locally available material of simple
shelter structures on a pilot basis (10% of the participating families).
The major problem with culture of sensitive crops during the rainy season
is the physical damage done to sensitive vegetable crops from incessant
rain, the presence of excessive free water on the surfaces of the plant
also predisposes the plant to disease infection. The elimination of
this direct contact of the rainfall onto the plant surface is a major
factor in allowing sustained vegetable production of these crops throughout
the year. These structures, which will each cover approx. 72m2 in area,
consist of a simple aluminum frame which has a long life, covered with
varying cladding materials depending on the requirement of the particular
agro-climatic zone, from fully impervious polyethylene sheeting, through
micropore cladding which allows air movement but will divert over 90%
of the rainfall from the enclosed plants, to open weave shade materials
which allow penetration of some of the rainfall. These cladding materials
have varying life spans from two to ten years, the choice of which cladding
to use will depend on local experience.
- Initiation of vegetable production on raised beds to provide improved
drainage characteristics. Raised bed technology, whereby soil from pathways
(at approximately 1.5m spacing) is excavated and used to build up the
depth of soil on the intervening spaces has three major advantages,
the pathway network acts as a drainage system to rapidly remove excess
water and reduces soil waterlogging, the added depth of soil increases
the available root zone of fertile top soil and hence encourages plant
growth, and the use of permanent beds that can be reached from pathways
reduces or eliminates soil compaction problems. The use of permanent
beds allows excellent weed management either through soil sterilization
or gradual elimination of the weed seed population by intensive weeding
through the entire year.
- Provision of a starter seed supply of adapted species and improved
vegetable cultivars adapted to the hot and humid conditions and meeting
the requirements of the local market, to each participating farm family.
The choice of the correct crop, and cultivar within crops, is essential
to the success of wet season vegetable production (as it is for any
season of production). Provision of small starter packs of specifically
adapted crops and cultivars to participating farm families will ensure
their successful exploitation of the improved protective structures
and soil management practices. The choice of crops and cultivars will
be based on locally available recommendations for tried and tested combinations.
- Construction of simple water reservoirs and supply of pipes and hoses
for water conveyance and better irrigation management. Crops adapted
to the wet season cultivation, by their nature tend to be drought susceptible,
provision therefore for sustained cropping needs to be made to supplement
periods of low rainfall with irrigation. Simple irrigation structures
can be constructed to tap the run off from the protected structure (family
residence), and store it for future use, or pump from a local irrigation
supply (river, water table, lake, etc.). Tapping of protective structure
run off, has an additional benefit in that it reduces the degree of
waterlogging of the surrounding area, which would be exacerbated by
the structure run off if left to percolate directly into the surrounding
soil. With a permanent raised bed system, a simple PVC pipe system can
be installed and buried (to protect from UV breakdown), with UV resistant
raisers at suitable intervals fed by gravity from the storage tank,
through a manually operated hose pipe for field delivery. This same
system can also be used to intensify production of higher water demanding
crops during the dry season, should a suitable water source be readily
available.
