WENCOMO, Hilda B; CEPERO, Bárbara  e  RAMIREZ, J. Seed production of Leucaena spp. on acid soil. Pastos y Forrajes [online]. 2010, vol.33, n.1, pp. 1-1. ISSN 0864-0394.

This work was conducted on a of Leucaena spp. collection that was established on acid soil in the Villa Clara province, with the objective of studying the seed production performance of this shrubby species on this soil type. Four treatments were evaluated (A, B, C and D), which were defined through the four quarters of the year, distributed according to a completely randomized design; in addition, the phenology was observed. A highly significant variation (P<0,01) in the total seed and pure seed yield, and the best result was obtained in treatment D. Besides, in this treatment the lowest weight of 1 000 seeds was observed, which represented a higher number of seeds per kilogram and a lower cost per kilogram of seed ($ 4,80). Variation was observed regarding the phenology patterns of flowering and fructification of the different studied species and accessions. The harvest of seeds from Leucaena is concluded to be more economical when it is carried out in the last quarter of the year under the conditions this trial was conducted.
