IRESO Project

moderated by Gloria Kyomugisha

This group serves for exchange and learning of tomato grafting in Uganda, Asia and the Netherlands and materials available to all.

Tomatoes serve as a source of livelihood for many rural farmers in Uganda, are produced by all gender groups and have potential for increasing income, improving living standards and employment creation. Tomato production and productivity in Uganda has been limited by Bacterial wilt 1. This project, with the goal of building wealth and resilience, will map the prevalence rate of bacterial wilt in Uganda, while identifying the resistant genotypes that can be used as rootstock for grafting with commercial genotypes.

Participatory on-farm and on-station trials will be undertaken for selection of resistant genotypes, to be used as root -stock. The Project will promote commercial seedling production nd grafted wilt tolerant tomatoes through participatory and inclusive approach by involving 20 commercial nurseries, managed by the 500 entrepreneurial youth and impacting on 4,000 farmers through best production practices, leading to improved wealth, resilience and Nutrition.

Objective framework

Overall Objective

Improving income, nutrition and resilience through sustainable production of grafted tomato with 4,500 beneficiaries in (Kabale, Wakiso, Mpigi, Mukono and Luwero Districts) Uganda.

Specific Objectives

Mobilisation situational analysis, mapping and access bacterial wilt and social economic impact of the disease in identified key tomato producing Districts in Uganda.

How to establish purple passion fruits orchard:

Passion fruit production is constrained by several insect pests, diseases and inadequate knowledge on the management of the crop among other factors. A grower needs to know a few basic facts about the crop.


The two types of commercially grown passion fruit.

1) The purple passion (Passiflora edulis f. edulis) This type of passion fruit is most suited to upper midland

and highlands (1,100 to 2,500m above sea level). It has purple colored superior fruits of 4-5 cm in diameter

which have an aromatic flavor. It is good for fresh market and Juice extraction for local and export markets

2) Yellow passion fruit (Passifl ora edulis f. fl avicarpa) This passion fruit is most suited to the coastal lowlands. It is more vigorous and has a larger fruit of 5-7cm. It is more acidic and used for juice extraction. Yellow passionfruit is resistant to Fusarium; wilt, tolerant to Phytophthora blight, nematodes and brown spot.

It is used as rootstock to purple pa

Grafting will reduce tomato bacterial wilt:

Tomatoes are one of the widely grown vegetables in the world. In Uganda, it is estimated that about three million homesteads grow tomatoes, some for home consumption and others, for sale.

Speaking at the launch of a key turning innovation, where tomatoes are grafted to keep away pests including the deadly wilt locally known as kiwotoka. The tomato wilt is the devil that threatens to destroy the souls of the tomato growers.

When we are planting our tomatoes, we pray that they are not visited by this devil, John Nsamba, a tomato farmer says. Nsamba grows tomatoes in Busiika in Luwero district. The wilt destroys tomato farms if infected plants are not isolated and identified early. Farmers want the right seeds and knowledge to achieve better yields and eliminate diseases, Karugu Macharia, the regional director of Solidaridad says.

For the plants to be grafted and to remain healthy, they should be watered the previous night so that when cut or graft

“Grafted Tomato” project launched in Uganda

The Applied Research Fund (ARF) project “Improved Resilience through Sustainable Production of Grafted Tomatoes in Uganda (IRESO)” was launched by Josephat Byaruhanga, Senior Policy Officer Agribusiness of the Embassy of the Kingdom of the Netherlands in Kampala. The launch took place on August 14, 2018, at the National Crops Resources Research Institute (NaCRRI) in Namulonge, Wakiso District in Uganda.

The Grafted Tomato project is implemented by a consortium of Solidaridad, National Agricultural Research Organisation (NARO), House of Seeds, Enza Zaden, Makerere University and AgriProFocus. It is funded by the Ministry of Foreign Affairs of the Netherlands through WOTRO, the Science for Global Development department of NWO (The Netherlands Organisation for Scientific Research), with lessons shared and disseminated by the AgriProFocus platform as well as Food & Business Knowledge Platform.

Kalumamba’s switch from potatoes to ‘Assila’ tomatoes yields handsome reward

After he completed his agricultural training course from Bukalasa Agricultural College Luwero in 2007, Micheal Kalumamba, 29, dived straight into farming, and started off by growing a variety of crops such as maize, sorghum, beans and potatoes. However, after two seasons of toiling, Kalumamba wasn’t impressed one bit with the income he got after selling his harvest, because of the low prices his produce fetched in spite of the fact that they had a long gestation period. 

“I would sell for example potatoes and beans to nearby markets and get about Shs 300,000 profits a season. This frustrated me and I thought of other crops to grow,” he said.

In 2011, Kalumamba decided to switch to tomatoes after he discovered that their demand had gone up. In fact, he specifically opted to grow ‘Assila’ because it is a type that has a lower gestation period—of only three months and with a long shelf-life sinc

Grafting: A way to boost tomato harvests from low-quality trees:

Many tropical fruit trees, including tomatoes, mango, avocado and orange, perform better when farmers merge good fruiting characteristics with resistance to disease. To accomplish this, a single stem is placed on to a root stock tree. The stem eventually merges with the root stock to form the main trunk of the tree and from then on that tree bears fruit similar to the plant the graft was taken from.

Bigger harvests

Grafting transforms low quality fruit trees into the high yielding commercial varieties. As such, these trees would be a better source of income as fruit producers each year than their value as wood products. It will ensure that the nature of the plant will be maintained and can perpetuate the specific variety of the plant yet if a farmer plants seeds, the resulting plant will not be identical.

The grafting technology, say scientists at National Crops Resources Research Institute (NaCCRI), has been embraced b

How to choose tomato varieties:

By Andrew Mefferd

Tomatoes are the most profitable crop on many market farms — if you choose the right varieties. But with thousands of varieties on the market and hundreds of new ones introduced every year, how do you know which ones to grow?

One of the best ways to figure out what varieties to grow on your farm is to look around at the farmers and gardeners in your area and see what they like. Asking what varieties they are not growing and why will help you learn from their mistakes and not waste production space on something that doesn’t work in your area. It’s always worthwhile to keep a little bit of field space devoted to on-farm trialing of new varieties to see if they work before going into production.

Most years at Johnny’s we trial roughly 300 varieties of tomatoes in the field, 50 in the hoophouse, and 10 to 15 different rootstocks for grafted tomatoes. It is a daunting task to evaluate 400 varieties every year and figure out which ones make se

AgriProFocus Facilitates Mapping of Soil Fertility and Tree Seedling Value Chains

This quarter AgriProFocus facilitated two sustainable value chain workshops in Ethiopia:  one on mapping soil fertility value chains for the Fertile Grounds Initiative held in Ziway, and one on mapping tree seedling value chains for GiZ at Menagasha. Members of the AgriProFocus Youth in Agribusiness Platform had the opportunity to participate in both workshops.

The interactive value chain mapping technique described in the AgriProFocus Gender in Value Chains Toolkits was used in both instances; workshop participants were supported to identify social, economic and environmental constraints and opportunities to the core and extended value chain of specific agricultural products (highland tree seedlings, lowland tree seedlings, compost, biochar, vermicompost, biofertilizer, and green manure seed).

Feedback from the tree seedling value chain workshop was very positive, feedback from the soil fertility works
