of banana genotypes resistant to pest and diseases:Five high
yielding Matooke banana cultivars (Kisansa, Mudwale/Mpologama, Kibuzi,
Namaliga, Mbwazirume) and five exotic cultivars (Kabana1, Kabana 2,
Kabana 3, Kabana 4 and Kabana 5) have been identified and are being
distributed to farmers. Kabana 3 and Kabana 4 are good replacement for
Bogoya but also have fairly good cooking qualities. Kabana 5 is a good
replacement for Kayinja and Kisubi beer bananas. Several utilization
options such as dry preserved bananas (porridge reconstitution and Karo)
are now being promoted to consumers. In addition to these selected improved
cultivars, a breeding programme to improve local matooke was established
and has delivered four promising matooke hybrids that have been selected
for further evaluation.
and biological control options: Cultural control practices for
banana weevil and nematode such as; use of clean planting material,
crop sanitation, weevil trapping using pseudostem and disc-on-stump
traps. Semio-chemicals (pheromones and Kairomones) and biological control
(Beauveria bassiana, parasitic ants) are also being developed for weevil
control. Use of break crops such as cassava and sweet potato is also
being recommended for banana nematode control. Enhanced plant nutrition
soil management practices that improve plant vigour such as use of organic
or inorganic manure and mulching are also recommended for management
of banana pests and diseases. All these practices are accompanied by
proper crop management practices such as timely weed control, pruning,
de-trashing and soil erosion control. Control options based on ash and
urine concoctions currently used by farmers are also undergoing validation.
Post-Harvest Handling and Storage Technologies
crop post-harvest losses have been estimated at 5-15% for cereals
and legumes, 20-25% for root and tubers and over 35% for fruit
and vegetables. Losses have been due to arthropod pests (insects and
mites), micro flora (fungi and bacteria), vertebrates (rodents and birds)
and man (action or inactivity).
enhancing shelf-life of commonly grown crop in Uganda include:
- Use of botanicals
(i.e. tobacco, tephrosia, tagetes) against bruchids;
methods (i.e. solarisation, parboiling, salting) control of a broad
spectrum of storage pests; solar and hybrid dryers for fruit and vegetables;
- Drying structures
(i.e. biomass-heated, racks/platform, cribs, mats) for cereals and legumes;
structures (e.g. brick silos, improved traditional granaries) for durable
- Pit and
clamp for fresh sweet potato;
media (sawdust) for fresh cassava;
and threshers, graters and chippers (root and tubers); and local baking
Management for Sustainable Production Systems
organic and inorganic (fertilisers) nutrient sources to reduce costs
and improve fertilizer use efficiency;
organic residues to supply nutrients to crops;
ways for handling and application of farm yard manure;
ways for preparing and applying composts;
biological nitrogen fixation into farming systems through use of grain
legumes and cover crops (for green manuring) to increase nitrogen
in cropping systems;
- use of
improved/shorter rest periods (fallows) that fit into the farming systems
while improving or maintaining soil productivity.
production heavily depends on rain-fed agriculture with only 55,000
ha (1.2%) of the 4,600,000 ha of farmland being irrigated. FAO estimates
that up to 50% of the potential crop yields in Uganda are lost annually
as a result of moisture stress, yet strategic development of supplemental
irrigation (other factors remaining constant) would increase overall
productivity and yields by 50-70% while making it possible to crop
the land 2-3 times annually.
consequently developed water harvesting recommendations for different
utilisation practices; NARO has developed recommendations for construction
of contour bands, terraces, grass strips, trash-lines, stone-lines
and other structures to manage soil and water to prevent erosion in
different farming systems/agro-ecological zones.
of developing comprehensive Agricultural Land Use Plans has been initiated
on a pilot basis starting with the districts of Rakai and Mayuge which
should lead to a more holistic approach to the management of land
resources and better planning for the country.
4. Horticulture technologies for a modernised and diversified agriculture
materials for the above and other fruits grown in the country.
propagation, nursery, and orchard management techniques have been
developed and many agricultural staff and farmers have been trained
in these areas.
- High yielding
Kawanda passion fruit clones are being cleaned of viruses and multiplied,
while collar rot resistant root stocks are being identified.
avocado varieties for local, export, and processing markets, and 6
mango varieties for high rainfall areas and more for the drier areas
have been identified. Five citrus cultivars, three of which are seedless,
and 2 pawpaw varieties for export have also been identified, and farmers
have been trained on selection of female pawpaw seeds from the local
pawpaws. Two apple and 2 pear varieties are being tested for production
in the highlands.
- IPM options
for the control of major fruit pests and technologies for post harvest
handling of passion fruits are also available.
bacterial wilt tolerant tomato varieties have been identified and
more are being screened. Two okra and 2 hot pepper varieties are available
for the export market. Rust resistant snap bean varieties are being
for the control of major pests and diseases of vegetables in Uganda
have been developed, and farmers have been and are being trained in
the safe and effective use of pesticides.
oil crops are grown and processed for their oils which are used as scents
and flavours by cosmetic, detergent, pharmaceutical, and household insecticide
industries, among others. One Geranium variety which produces oils acceptable
on the export markets has been identified.
