PENTON, Gertrudis. Technical Note: Productive performance of mulberry subject to two alternatives of organic fertilization. Pastos y Forrajes [online]. 2007, vol.30, n.4. ISSN 0864-0394.

A study was carried out in areas of the EEPF “Indio Hatuey”, with the objective of evaluating the agronomic performance of mulberry (Morus alba L. var. Acorazonada) before two alternatives of organic fertilization. The soil of the site is hydrated Ferralitic Red; rainfall oscillated between 1 000 and 1 145 mm per year. In the establishment cutting highly significant variations were obtained among the treatments: control without fertilization, association mulberry-Albizia lebbeck as green manure vs mulberry fertilized with organic matter (41,6; 45,0 and 72,4 g of edible dry biomass per individual, respectively). Nevertheless, in the rainy season of the second year of exploitation, the cumulative production did not show significant variations between the association and the fertilized mulberry (88,8 and 86,7 g edible dry biomass per individual), although it did with regards to the control which produced only 40,7 g. The contribution of organic matter to the soil during the establishment of the mulberry plantations and/or the association of A. lebbeck managed as green manure provide a significant advantage in the productive response of the forage shrub, and the second alternative stood out for its endogenous character.

Keywords : Albizia lebbeck; green manure.
