OROPESA, Katerine; PENTON, Gertrudis  e  MARTIN, G. J. Effect of biological and/or mineral fertilization on mulberry (Morus alba L.) forage production (Technical note). Pastos y Forrajes [online]. 2011, vol.34, n.3, pp. 295-302. ISSN 0864-0394.

A study was conducted during a year in areas of the EEPF “Indio Hatuey”, in order to study the morphoagronomic response of Morus alba L. cv. Tigreada associated to Canavalia ensiformis as green manure, inoculated with mycorrhizas through the product EcoMic® (biological fertilization), and their combination or not with mineral fertilization. Treatments consisted in: control (C), mineral fertilization (MF), biological fertilization (BF) and combined mineral and biological fertilization (MF + BF) in both seasons. Mineral fertilization consisted in N and K, at a rate of 300 and 150 kg/ha/year, respectively. The intercropping of C. ensiformis as green manure inoculated with AMF, caused in the rainy season an improvement of the productive response, without affecting the utilization of forage as edible biomass (6 250 kg of leaves/ha and 18 194,4 kg of fuel biomass). To continue the studies is recommended in order to determine the optimum combination of mineral and biological fertilization that allows increasing the yield and the fresh stem:ligneous stem ratio
