Seeding Date and Density for Avena strigosa Schreb. and Lolium multiflorum Lam. for the Alto Vale do Itajaí Region, Santa Catarina State, Brazil

[摘要] - The experiment was conducted for three years at the Epagri, Ituporanga Experimental Station, located on Southern Brazil (27º 38'S, 43º 60'W), to evaluate the best seeding date and density for Avena strigosa Schreb. and Lolium multiflorum Lam. at the Alto Vale do Itajaí Region. The experimental design was based on randomized blocks, with subdivided plots and three replicates. Time treatments were: T1 = middle of March; T2 = middle of April; T3 = middle of May; T4 = middle of June. Densities for A. strigosa were 60, 80 and 100 kg/ha and for Lolium multiflorum, 15, 25 and 35 kg/ha. Results showed A. strigosa less productive but more precocious that Lolium multiflorum, but no significant differences were observed on seeding density. The best time for seeding both species was April.
