MAZORRA-CALERO, Carlos A et al. Technological and socioeconomic diagnosis of the establishment of Psidium guajava L. and Teramnus labialis in Ciego de Ávila, Cuba. Pastos y Forrajes [online]. 2016, vol.39, n.4, pp. 259-264. ISSN 2078-8452.

In order to characterize the establishment of the polycrop of guava tree var. enana roja cubana and Teramnus labialis, a study was conducted during seven months, in 1,66 ha. All the investments in the area were monitored, as well as the agrotechnical activities and the costs of the system, which allowed to observe that: a) the agrotechnical activities performed on the guava tree were similar to the ones carried out on the fruit tree in the traditional system, and 12 % of the total work time was dedicated to the establishment of the legume; b) it is essential that there is water availability throughout the area, as well as 0,008 ha of seed bank of the legume to guarantee the planting in each diversified hectare; c) most of the work time is dedicated to irrigation, which can be combined with the manual control of weeds and the formation pruning of the fruit tree; d) the cost of the diversified hectare was approximately 26 000 CUP, from which 70 % was related to the acquisition of the guava seedlings and the irrigation system, while 28 %, to salary and fuel expenses. It is concluded that the guava-cover legume polycrop system differed little in agrotechnical management and in costs from the traditional system which is currently used to cultivate the guava tree in Cuba.
