 Abstract

The banana farming system in Bukoba, Tanzania is confronted with declining productivity contributed by shortage of external inputs such as mulch from grassland (Rweya) the source of organic materials for home garden (Kibanja). This was an explorative study, which used Multiple Goal Linear Programming (MGLP) model to indentify options for sustainable Kibanja productivity. The model allocated 0.021 ha for annual crops sufficient to produce at least 50 kg DM of sweet potatoes in all Farm Types (FT) as requirement of household food security. In the absence of cattle, the Rweya was not allocated for FT1. However, FT2 and FT3 would require 0.24 and 0.53 ha of Rweya, respectively, during long rainy season, whereas 0.26 ha and 0.57 ha were allocated during short rainy season for supplying mulch to the respective Kibanja. Herbaceous legumes were chosen by the model for growing in the Kikamba that would supply adequate nutrients nitrogen (N) and potassium (K) in form of green manure for optimum Kibanja productivity. Labour at family level for farm activities amounted to 35%, 25% and 39% for FT1, FT2, and FT3, respectively. It was concluded that Kibanja productivity would be sustained if there is sufficient land to supply adequate organic materials.
