WENCOMO, Hilda B  and  LUGO, Yudith. Yield of dry matter and other components in Leucaena leucocephala cv. Cunningham using Liplant. Pastos y Forrajes [online]. 2013, vol.36, n.1, pp.43-49. ISSN 0864-0394.

In the Agricultural University of Havana biostimulators are produced which have been successfully used in the agricultural production of different plant species. Among them is Liplant a product derived from earthworm humus containing hormonal fractions-, with which satisfactory results have been obtained in the in vitro propagation of several crops, as well as in ex vitro applications of others. The objective of this work was to determine the influence of the doses of this product on the bromatological composition and growth, as well as the yield of DM and some of its components. A factorial design was used under semi-controlled conditions and three treatments: 0, 1/20 and /40 (v/v), with two studied factors: without fertilization and with fertilization, on a lixiviated Ferralitic Red soil. Significant difference (P<0,05) for plant growth and number of shoots with the application of Liplant in the dilution1/20 was found ; while no differences were found in the dry matter yield when applying the product. The analysis allowed to conclude that the dilution 1/20 favored the evaluated indicators, except the DM yield, althoughr it is necessary to test these results under field conditions.
