Description
Winter cereals genotypes (oats, wheat, rye, barley, and triticale) were evaluated for forage and grain yield at the experimental area of the Wheat National Research Center (EMBRAPA/CNPT) and Agronomy College of the Universidade de Passo Fundo (UPF/FA), in Passo Fundo, RS state, southern Brazil, during the years 1992-94. Three cutting frequencies were applied: no cutting, one and two cuttings. A completely random block design with split-plots and three replicates was used. The crops were established under conventional tillage. The fertilization was 200- 300 kg/ha 5-25-25 , plus 22.5-30.0 kg/ha of N (urea) during tiller period (before 45 days after planting date). The cereals were planted on May 3-17, by hand, using 60-100 seeds/m in rows spaced 0.2m apart. The forage was cut by hand when the plants had approximately 30 cm of height at 7 cm of the soil level. Dry matter yield, grain yield, crude protein yield, and crude protein content were determined. The rye BR 1 showed the best performance for forage, and crude protein yield. Hectoliter weight, density, and emergence-flowering period were determined. The rye BR 1 showed the best performance for forage and crude protein yield, whereas oats UPF 15 was outstanding for grain yield. In addition, triticale BR 4, wheat IPF 55204, and PF 87451, and oats UPF 13, UPF 14, CTC 2, and UFRGS 12 were promising for double purpose, early grazing and harvest.
