The objectives of this study were: i) to determine the average length of the phenological subperiods Tillering - Stem elongation (Til-St), Stem elongation - Flowering (St-Fl) and Flowering - Physiological Maturity (Fl-PM), ii) to assess the forage production at the winter-end, and iii) to estimate the seed Production, in the south region of Santa Fe province. The determinations were performed on an area of 1000 m2 located at the Campo Experimental Villarino, (33º 01´ LS and 60° 53´ LO and 50 m above the sea level). The experimental plot was sown on November 14th 2014. Evaluations were conducted during the growing seasons: 2014-2015, 2015-2016 and 2016-2017. Phenological determination showed that the average length of the phenological subperiods were: Til-St 46 d, St-Fl 20 d and Fl-PM 21 d. On the other hand, the mean forage yield was 4,642 kg DM/ha and the seed yield estimation was of 381.20 kg/ha. Results of this work show that cv. Boyero UNNE is a promising material to be introduced by sowing in both, fertile and marginal areas of southern region of the Santa Fe province with double purpose of forage and seed production.
