2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Species of Mangoes and Oranges planted for income and food security.

2.2 Detailed description of the Technology

Description:

Growing mangoes and oranges is becoming a common practice among farmers in Northern Uganda for food security and increased household income. As seasons become shorter and erratic, failure of traditional crops like beans and maize is increasing. Mangoes and oranges are more adapted to sub-humid conditions and can endure longer dry spells yet yield well. Thus, farmers are taking on improved varieties of mangoes and oranges developed by the National Agricultural Research System. The mango and orange seedlings are planted with only spot weeding to maintain the grass cover for soil moisture. The activities involved in establishing the orchards include (1) linking up with the extension worker for information on what varieties and how to plant on which type of soils (2) site selection (3) buying seedlings (4) planting and (4) watering if planted during the dry season with the following input requirements seedlings, hired labour of at least 2-3 people paid on monthly basis and watering can. At the time of planting the land user digs a hole up to a depth of about 0.5 metres using a fork so that the roots are allowed to grow out easily and plant the fruit trees spaced at 10 metres x 10 metres allowing the grass to grow without removing or cutting. If planting is done in the dry season and the ground is too dry the farmer applies water once a week slowly using a bucket so that it has time to sink in the soil. If the land user plants during the wet season, watering is not necessary. This practice is liked because yields are high due to leaves litter as well as the demand for fruits in addition to being easily fertilised using organic fertilizer locally obtained and treated . In the long run, the high costs incurred at the time of establishment in buying seedlings and paying labour. The presence of fruits from the orchard provides both food and income to the household, which should be other crops such as maize and sim fail due to drought. What is not liked about this technology is that the grass grown in the garden is liked by livestock during the dry season. Herdsmen searching for pasture drive their animals into the gardens, resulting into constant conflicts between livestock owners and the land user. The grass also poses a risk of fire during the dry season. Additional efforts to put in place a community bylaw on controlled grazing would reduce conflicts and free range grazing of animals contrarily to fencing which may be an additional benefit to sustainably managing land by the land user.

No

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
Appropriate for small and large scale land users.
The technology can be replicated elsewhere by other farmers.
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Good at providing income when mangoes and oranges are sold.
Appreciated by the land user due its ability to provide household income and fruits for consumption and sale.

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view How can they be overcome?
Requires skilled labour at the time of establishment to dig the holes and applying the right spacing. Train family labour to acquire the skills.
Use extension workers and expert farmers to provide the skills
The technology is liked by thieves since it provides income and food. Fencing to prevent intruders from piking the fruits without payment.
Put in place strict byelws and harsh penalties for offenders.
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
Fruit trees are having canopies in close contact hence reduced fruiting with the spreading of branches. The technology is not well managed as would be expected. The farmer should trim the branches.
