2.1 Short description of the Technology

Definition of the Technology:

Different varieties of mangoes such as Banganapalle, Alphonso, Kesar, Haden, Bombay, Kent, Keitt, oranges such as Washington Navel, Valencies, Tangarine, jack fruits and avacados are grown for purposes of household income and soil fertility improvement.

2.2 Detailed description of the Technology

Description:

Home fruit tree groves of grafted mango (mangifera indica) and citrus (citrus aurantium) is a farming practice that farmers practice in Northern Uganda to diversify their economic activity, for soil fertility improvement and household income.

Northern Uganda has tropical savanna climate which receives moderate amount of rainfall ranging from 750-1000mm per annum. The soils are moderately fertile with less organic matters coupled with soil erosion, which leads to low crop productions hence low incomes. The moderate rainfall is also unreliable which makes the region to experience drought. Farmers grow fruits as an alternative source of income.

This land user generates over 90% of his household income from fruit growing. The planted fruit trees increase the organic matter content in the soil when dry leaves decompose, rooting prevents soil erosion, pruned brunches are a source of fuel wood and trees acts as wind breaks. Major fruits grown include jack fruits, grafted mangoes, oranges and avocados.

For all these fruits, seeds are first planted in a nursery bed for a period for about two months with the following required inputs: hoes, pangas, spades, wheelbarrows, and shovels. Afterwards, transplanting into the gardens is done. Selection and clearing of the field is done and the planting holes are marked. Excavation is done in accordance to the slope direction: the top soil is put on the hillward side of the planting hole then the sub-soil is put on the downward side of the planting hole. The planting holes are dug in a square shape at 60*60 cm. Composite manure is mixed with top soil and applied into the hole to speed up the seedling establishment and to enhance growth. When planting, the hole is not fully filled but ends 5 cm below the surface so to enable water harvesting, moisture retentions and infiltration. This ensures ample soil moisture and water supply to plants.

The spacing for avocados is 8 × 8 m (65 seedlings/acre), jack fruits is 10 × 10 m (44 seedlings/acre), mangoes 10 × 10 m (44 seedlings/acre) and oranges 4 × 5 m (200 seedlings/acre). After planting, mulching is done by saw dust, kitchen waste like groundnut husks, vegetables and so on. 75 mangoes, 150 oranges, 20 avocados, 20 jack fruits and 4 grapes trees are spread evenly over the planting area. To realize maximum production, the land user needs to have constant water for irrigation.

On the other side, fruit tree growing has brought negative feelings from neighbors who don't promote this practice. Fruit farmers' lifestyle has changed due to revenues realised from growing fruit trees. To maintain this technology, weeding, pruning and creating fire lines during dry seasons to protect the farm is very critical . The technology is highly susceptible to pests and diseases that may require support from the local extension worker from time to time to be able to obtain high yields.

Before establishment the technology requires some knowledge and skills on fruit growing which can be extended by the extension worker who are located far from the land user. Associated with high costs in terms of transport and allowances to the land user.	Training and capacity building of local land users / experts. Training champion farmers. Establishment of learning sites / demonstrations.
Prone to climate change	Irrigation during the dry season
Requires water supply	Irrigation during dry seasons

Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view	How can they be overcome?
