2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Oranges (Citrus sinensis) and Mangoes (Mangifera indicate) integrated with beans are planted together in the same field to increase production and household income.

2.2 Detailed description of the Technology

Description:

The technology is promoted by small scale farmers in Northern Uganda to address soil degradation including soil erosion, low crop productivity and low-income challenges both on farm and at household level. The farmer identified land with average size of 0.6 acres situated on a gentle sloping area (3-5%), measuring 45m wide x 95 m long planted with mangoes spaced 10m × 10m and oranges spaced 4m x 5m integrated with beans, NABE 14 and K20. The beans were planted using a line spacing of 10cm within a line and 30cm between lines with 2-3 seeds per hole. The selected bean varieties are high yielding and marketable. The following are the labour and input requirements for establishing this technology: a hoe, a tape measure, seedlings, 4 people and a panga.
Integration of beans into an already grown mango and orange field is a good and profitable practice because decomposition of the plant litter increases yields of the beans (nitrogen fixing) and the cost incurred, for example in weeding is less compared to the costs which would be incurred when the three enterprises (oranges, mangoes and beans) are planted separately on the same land.
Generally, benefits from implementing this technology are slightly positive ranging from improved soil fertility due to plant litter, reduced soil erosion with the fruit trees providing shade to the beans. After harvesting the beans, the farmer uses the bean waste/ residues as mulching material for the orchard which subsequently decomposes to provide manure. Also the beans cover reduces the moisture evaporation from the soil, thus keeping the soil moist
However, oranges, mangoes and beans are affected by pests and diseases and in case of this; the farmer is likely to suffer since they are planted in one field. The role of the extension worker is very critical at this stage in providing extension advisory services on how to spray the fruit trees when they get affected.
