2.1 Short description of the Technology

Definition of the Technology:

Fruit trees of Mangoes (Mangifera indica) and Oranges (Citrus sinensis) are grown on degraded land to improve soil fertility through deep soil nutrient mining and litter of leaves.

2.2 Detailed description of the Technology

Description:

Fruit tree growing, with focus on mangoes and oranges, is a rewarding investment promoted by farmers in Northern Uganda with the aim of increasing fruit production for home consumption and income, and restoration of degraded land. On a farm located on a steep slope and measuring 40m x 100m (i.e. 1 acre), the land user select and plant disease tolerant, high yielding and marketable orange varieties (e.g. Valencia and Anlin) and mango varieties (Apple and Tommy) using spades, hoes, and pangas to excavate and dig up planting holes, 30 cm deep, with fruit trees planted at a spacing of 10 m ×10 m, during the rainy season; with 7 Cows, 5 goats and 4 sheep kept animal manure provision to apply on the technology using hired labour and supported by family labour. After establishment, the farmer keeps on observing the changes over time to see what is taking place with regard to vegetation growth, performance of fruit trees and how the visible soil properties are changing e.g. the colour showing a black sign of organic matter built up and soil health improvement.
Oranges and mangoes are susceptible to pests and diseases, which require money to buy pesticides and paying, as well as for hired labour for spraying. The farmer needs to be aware of these associated costs, which are rather high after establishment. Efforts by the farmer to integrate trenches within the degraded field is an additional option for the farmer to help enhance soil and water conservation by reducing water runoff. This is labour and capital intensive but beneficial in the short and long run.

Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
The technology is appreciated by the farmer and this is a sign of ownership - sustainability.

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?
Very laborious (planting, wedding and watering).	Use family labour.
Very expensive - buying seedlings and hire of labour.	Join savings groups that give loans at low interest rates (3%).
Benefits are realized after a long period.	The land user can look for alternative sources of income to supplement the technology. Engage in selling seedlings as a business to those who may want to start establishing this technology.

Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view	How can they be overcome?
No integration with other agroforestry trees for fodder yet as the land user has livestock.	The technology need to be integrated with agroforestry trees (callindra, Grivellea ) for fodder since the land user has livestock.
