Abstract

PLANA-LLERENA, Rodolfo R.; GONZALEZ-CANIZARES, Pedro J.  and  SOTO-CARRENO, Francisco. Combined use of Ecomic^®, Fitomas-E^® and mineral fertilizers in the forage production of animal food based in triticale (x. Triticosecale Wittmack), cv. INCA TT-7. cultrop [online]. 2016, vol.37, n.4, pp. 76-83. ISSN 1819-4087.  http://dx.doi.org/10.13140/RG.2.2.34452.30087.

The study was aimed to decrease the application of mineral fertilizers in the production of triticale-based forage, with the combined use of EcoMic^® (arbuscular mycorrhizal fungi) and Fitomas-E^®. It was developed on a red Ferralitic leachate soil in the Station of Pastures and Forage Genetics Cattle Company (EPG) “Niña Bonita”, Artemisa province. The treatments were: 1. Absolute Control; 2. Application of mineral fertilizers 150, 92 and 120 kg ha^-1 of N, P₂O₅ and K₂O; 3. Application of mineral fertilizers 100, 54 and 70 kg ha^-1 of N, P₂O₅ and K₂O + EcoMic^® (15 kg ha^-1) + Fitomas-E^® 2 L ha^-1. Mycorrhizal variables, the percentage of N, P and K in the leaf tissue and crude protein percentage in forage were analyzed. The dry mass (forage) in kg ha^-1. The results showed that a decreased amount of mineral fertilizers did not reduce the quality of the fodder produced, since no significant differences among control treatments production and use of biofertilizer were recorded. Moreover higher percentage intensity and mycorrhizal colonization and the highest number of spores per g^-1 soil was recorded. The results showed the establishment of a mycorrhizal association among guest and host. It was recorded savings in production costs with the implementation of these, so it became more profitable to produce forage

Keywords : inorganic fertilizers; biofertilizers; vesicular arbuscular mycorrhizae.
