Nitrogênio e métodos de semeadura no rendimento da forragem de pós-colheita de sementes de milheto [Pennisetum glaucum (L.) R. Br.] Nitrogen levels and sowing methods on forage yield produced after harvesting of millet seed [Pennisetum glaucum (L.) R. Br.]

Um experimento de campo foi realizado para avaliar o efeito de doses de nitrogênio (N) (0, 60, 120 e 180 kg/ha) e métodos de semeadura (a lanço; 0,40; 0,80; e 1,20 m entre linhas) sobre o rendimento de matéria seca (RMS), a densidade de perfilhos e os teores de proteína bruta (PB) e minerais (P, K, Ca e Mg) do material de pós-colheita de sementes de milheto. O delineamento experimental foi blocos ao acaso com os tratamentos dispostos em parcelas subdivididas, alocando-se os métodos de semeadura nas parcelas principais e as doses de N nas subparcelas. As doses crescentes de N influíram no RMS, rendimento de PB (RPB), número de perfilhos totais/m² (NPT) e teor Mg na matéria seca (MS) da forragem, porém as respostas variaram conforme o método de semeadura. Maiores RMS e NPT foram observados no método de semeadura com 0,40 m entre linhas. O maior RMS (8872 kg/ha) foi obtido com a dose de 120 kg/ha de N e o maior RPB (688,8 kg/ha), com a dose de 180 kg/ha de N. No método de semeadura com 0,80 m entre linhas, os teores de Mg na MS de milheto aumentaram de forma quadrática, em resposta às doses de N, enquanto no método de semeadura com 1,20 m entre linhas a concentração do mineral aumentou linearmente.<br>A field trial was carried out to evaluate the effect of nitrogen (N) levels (0, 60, 120 e 180 kg/ha) and sowing methods (broadcast and .40, .80, and 1.20 m between rows) on dry matter yield (DMY), tiller densities and crude protein content, and minerals (P, K, Ca and Mg) of the material of post harvesting of the millet seed. A completely randomized block experimental design with the treatment in a split plot arrangement was used, with the sowing methods on the main plots and N doses on split-plots. The increasing N levels affected the DMY and crude protein yield (CPY), number total of tillers (NTT), and Mg content of the forage dry matter (DM). However, the response changed according to the sowing methods. The highest DMY and NTT were observed in sowing methods with 0.40 m between rows. The highest DMY (8872 kg/ha) was observed with 120 kg N applied, and the highest CPY (668.8 kg/ha), with 180 kg/ha N. In the sowing method with 0.80 m between rows the Mg contents in the millet DM quadraticly increased, while in the sowing methods with 1.20m between rows the concentration of the mineral linearly increased

Nematóides do Brasil. Parte V: nematóides de mamíferos Brazillan nematodes. Part V: nematodes of mammals

<abstract language="eng">A survey of nematode species parasitizing Brazilian mammals is presented, with enough data to provide their specific identification. The tirst section refers to the survey ofthe species, related to 21 superfamilies, 45 families, 160 genera and 495 species that are illustrated and measurement tables are given. The second section is concerned to the catalogue ofhost mammals which includes 34 families, 176 species and their respective parasite nematodes. The identification of these helminths is achieved by means of keys to the superfamilies, families and genera. Specific determination is induced through the figures and tables as above mentioned
