ROJAS G., Claudio; CATRILEO S., Adrián; MANRIQUEZ B., Moisés  y  CALABI F., Francisco. An evaluation of the cutting stage on triticale (X Triticosecale Wittmack) for silage. Agric. Téc. [online]. 2004, vol.64, n.1, pp.34-40. ISSN 0365-2807.  http://dx.doi.org/10.4067/S0365-28072004000100004.

At the Carillanca Research Center, 38º41’ S lat, 72º25’ W long, 200 m.a.s.l., of the National Agricultural Research Institute (INIA), in a transitional dryland soil, a study was conducted in order to evaluate the chemical qualities of triticale (X Triticosecale Wittmack) cv. Tolhuaca INIA as whole plant, to determine the optimum cutting stage for the elaboration of silage. The crop was sown on April 19, 1999 to evaluate ten treatments corresponding to the following phenological stages of triticale early boot (T1); visible spikes (T2); beginning anthesis (T3); anthesis in progress (T4); aqueous grain (T5); milky grain (T6); milk-flour stage (T7); flour stage (T8); soft flour stage (T9) and hard grain (T10). A randomized complete block design with three replicates was used. The DM production results were statistically analyzed through simple regression analysis. The relations between chemical parameters and DM production indicated that the optimum stage for harvesting triticale for quality silage was at T4, with 210 days of growth, 29.5% DM, 70.6% in vitro digestibility (DIV), 7.6% crude protein (PC), a metabolizable energy content of 2.46 Mcal ME kg-1 and 21.5 t DM ha-1.

Palabras clave : triticale; harvesting time; quality; yield.
