Controlo das lagartas da maçã do algodoeiro (cotton bollworms) com a utilização de formigas predadoras, Uganda

O insetos são o principal constrangimento da produção agrícola no Uganda. A Helicoverpa armigera (bollworm americana), Earias vittella (lagarta da maçã) e Pectinophora gossypiella (lagarta rosada) estão entre os dez insetos que se alimentam e danificam os botões florais, flores, maçãs jovens e maduras do algodoeiro, provocando o aborto de até 87% dos frutos e na consequente redução da produtividade e rendimento do agricultor. Esta tecnologia da NARO (National Agricultural Research Organisation - Uganda) descreve o uso de formigas predadoras como meio de controlo biológico das lagartas da maçã do algodoeiro.

Maize production, Uganda

The National Agricultural Research Organisation (NARO) aims to enhance the contribution of agricultural research to sustainable agricultural productivity, economic growth, food security and poverty eradication through generation and dissemination of appropriate technologies, knowledge and information.The following technology describes the different steps for the management of the maize production and weed control.

Improved feeding of diary cattle for increased milk production and income, Uganda

Having well nourished and healthy livestock represent a challenge for the farmers in Uganda. Diary cattle in Uganda in most cases produce less milk than expected. This is mainly caused by improper feeding which provides feed in inadequate quantities and of low quantity. It is therefore imperative that feed quantity and quality be improved for diary cows in Uganda to increase milk production and subsequently household incomes. There exist technologies to improve the quality of the fodder e.g. introducing legumes in the cropping system. This has a significant impact on the soil and livestock if introduced to the farming and livestock system following certain criteria. This technology gives some examples of legumes which can be inter-cropped with grasses to improve the quality of animal fodder.

Management of cotton bollworns using predators ants, Uganda

Insect pest are the most important production constraints in Uganda. American bollworms, Spiny bollworms and Pink bollworms are among the ten insect pest feeding and damaging flower buds, flowers, young and maturating bolls causing abortions amounting to up to 87% resulting to yield reduction and income for the farmer.The following technology from NARO describes using predator ants as a biological mean to suppress bollworms.

How to produce Mirrow Carp fry (Cyprinus carpio), Uganda

The commonly farmed fish in Uganda, the Nile tilapia, grows very slowly in the cooler regions like Kabale, Kapchorwa and parts of Mbale and Kabarole. In 1957, the Mirror carp (simply called Carp), was introduced into Uganda from Asia. Carp unlike tilapia takes 8 months to attain an average weight of 500g. In similar region, the tilapia reaches an average weight of 100g in a year. Therefore Carp is recommended for these regions. However, Carp does not produce fry easily in ponds. This technology explains the process and steps to be followed to produce Carp fry in ponds.

Post harvest handling and processing of fish, Uganda

Fish in the cheapest source of animal protein and contributes 50-100% of animal protein in developing countries and 12% worldwide. Fish is the second earner to national economy in Uganda. It is also the best source of income to the fisherfolks. However, it is a perishable commodity, which deteriorates in quality within a short time if not properly handled and processed immediately.

The control of common predators of pond fish, Uganda

Fish is an important source of food and income for many poor households in Uganda. Fish farming also relieves the fishing pressure on natural water bodies. However, fish in ponds have a lot of enemies called predators which either injure or kill the fish in the pond. This reduces the amount of fish caught at harvest time as well as the quality of the harvested fish as a result of injuries they sustain from these predators. The farmers have complained that predators are mainly responsible for fish losses to their ponds.

Supplementary feeding for farmed fish

Most fish farmers believe that fish is a wild animal. They think that once put in pond water, it will survive naturally without adding any food supplement. This has resulted in pond fish taking a long period to reach a reasonable size. Most farmers add manure like cow dung and chicken droppings. This technology focused on supplementary feeding and lists some recommended types of fish for farming in Uganda.

Raising citrus rootstock, Uganda

Improved citrus varieties are not resistant to soil borne pests and diseases. However, they can be successfully grown if grafted on resistant rootstocks like rough lemon. Rough lemon is quick growing, drought resistant, shortens maturity period and is resistant to pests and diseases.

Improved method of preserving hides and skins

Hides and skins, if not well preserved, are of very little economic and commercial value. Because of this neglect, hides and skins produced in the country, particularly the Lango Farming System, go to waste.
