Abstract

Inga alley cropping is in promotion in tropical America, including Belize in the district of Toledo. This approach consists of a 4 m-wide alley intermitted with row of Inga edulis with a density of 2500 trees/ha. Inga seedling production is normally done with seeds planted in bags at a nursery. The associate cost of this production and the unorthodox seeds of Inga edulis are factors influencing the adoption of this agroforestry system. The first objective is to estimate the efficiency of vegetative propagation of Inga edulis in a non-mist polypropagator. The second is to evaluate the time of production of seedlings and setting-up of the system by vegetative propagation as well as by the methods of propagation by seeds in a tree nursery and but also in direct seeding in the fields. The third objective consists of evaluation of factors playing on the acquisition and the production of seedlings of trees by the small producers of the region. This objective was met by carrying out twenty semi-structured interviews with small producers from seven villages and three NGOs of the Toledo district. According to the results, cuttings production with a non-mist polypropagator is interesting and shows rooting rates above 75 % for several treatments. The various methods of propagation demonstrate times for establishment of the agroforestry system of 78 Man-days/ha for the sowing in bag, of 72 md/ha for cuttings and of 61md/ ha for field direct sowing. The transport of vegetal material towards the plantation sites seems to be a key limiting factor for establishment of the system identified from interviews and from the evaluation of establishment methods. A greater distance from fields favors the use of direct sowing. Local consultations combined with field trials permitted definition of the best methods in diverse situations for Inga alley cropping establishment.
