This study describes and analyses the existing storage system for grains and legumes by small scale farmers in Maputo Province, Mozambique. Interviews were conducted with 24 farmers in Boane and 23 farmers in Marracuene [date not given]. Results are reported in four main areas: the post-maturity farming system; pest control; storage methods; and losses. Maize was the main crop in both districts. It was field dried and stored on the cob. The farmers stored only for self-subsistence and sold only fresh maize. Rats and insects were the major agents of losses. There was a lack of knowledge concerning pest control methods. Pest control methods were not considered to solve the pest problems, instead the farmers accepted losses as inevitable. The general storage method in Boane was the elevated, ventilated granary (79%). Four main types were identified. In Marracuene, there was more variation in storage methods, the most common being to store in sacks. The farmers had no perception of qualitative losse

s in food grain. The only considered aspect of quality loss was seed viability. Mean value for losses of maize was 38%, as estimated by farmers in both districts. Losses for other crops varied from 19%-33%. The conclusion is that losses are big enough for taking progressive steps of action. Improved post-maturity farming systems will enhance both economic and qualitative aspects. This includes design of stores as well as handling systems and time of harvest. Other measures needed are: education and an intensified extension service; improved supply of construction material; and improved marketing facilities.
