Production of hydroponic fodder of triticale with common vetch

Abstract

An experiment was conducted at the Colégio Politécnico da Universidade Federal de Santa Maria (UFSM) – RS, in order to evaluate the production of hydroponic fodder of three varieties of triticale (X Triticosecale Wittmack): BRS Saturno, BRS Ulisses and Embrapa 53 at the densities 2.0 kg m^-2, associated with four densities of common vetch named SS Ametista(Vicia sativa L.) at doses of 0, 150, 300 and 450 g m^-2, during the winter of 2011. The experiment was conducted in a high tunnel with each treatment in an area of 1.0 m^-2, using a nutrient solution described by Santos et al. (2004). Evaluations were performed at 17 days after sowing. Varieties BRS Ulisses and Embrapa 53 had the highest average yield with 19.867 and 19.328 kg m^-2, but the maximum productivity was 22.313 kg m^-2 yielded by BRS Ulisses associated with 300 g m^-2 of Smooth Vetch, which indicates the success the use of this vetch.
