“…The NDF content increased linearly with the increasing of nitrogen dosages to the variety ADR 300 and decreased linearly to the hybrid ADR 7010. The values found are lower than those noticed by AMARAL et al (2008) and GUIMARÃES JR. et al (2008) wich studied cultivars of millet, and found values of NDF ranging from 60.15 to 68.63 and 70.50 and 71.2dag kg -1 DM, respectively. The low values of NDF observed in this study may be due to drought stress suffered by the culture, due to low rainfall observed during the experimental period.…”

“…The pearl millet is grass specie has been widely used by farmers as an alternative to reach the animal requirements in the critical period of the year, due to the fact that it is the forage more resistant to drought and is adapted to low soil fertility, presents fast growth and high yields of phytomass by unit area (AMARAL et al, 2008). It is a culture that shows good development in regions with low rainfall profi le, so, it has been widely used for the production of grass silage during periods of late season and in regions that are characterized by having problems with dry periods or drought (GUIMARÃES JR. et al, 2010).…”

“…The grass allows rotation between grain production and animal production, being a form of agriculture/livestock integration. In this type of management, millets are usually sown after the harvest of the summer crop, known as second crop (Amaral, Evangelista, Salvador, & Pinto, 2008). With the growth of livestock production, millets began to be used as bulk in the form of pasture and silage, which consists of a dual-purpose crop, serving for grain production and mainly forage production, given the high quality of the product compared to other forages (Kollet, Diogo, & Leite, 2006).…”

ABSTRACT. The objective of this study was to assess agronomic characteristics and nutritional values of silages of millet genotypes. Planting was done in randomized blocks, with five replicates per genotype. Green matter yield for genotypes ADR 500 and CMS 01 was higher and similar to each other, with 40.16 and 41.36 t ha (p > 0.05). There was no significant difference for dry matter yield, with the mean being 9.93 t ha (p > 0.05). The silages were similar (p > 0.05) as to pH, Aw and N-NH3/TN, presenting values of 3.92, 0.97 and 7.64%, respectively. There were no significant differences (p > 0.05) concerning the bromatological composition of the silages of the different genotypes, with a mean of 30.74% of dry matter, 10.21% for crude protein and 58.69% for neutral detergent fiber (p > 0.05). The dry matter digestibility mean stood at 59.90%. Based on the nutritional values and digestibility of the millet silages, the five genotypes are suitable for silage production, with potential for the North of Minas Gerais.Keywords: digestibility, dry matter yield, silage.Desempenho agronômico e valor nutritivo das silagens de milheto RESUMO. Objetivou-se com este trabalho avaliar as características agronômicas e o valor nutricional das silagens de genótipos de milheto. O plantio foi realizado em blocos casualizados, com cinco repetições por genótipo. A produção de matéria verde para os genótipos ADR 500 e CMS 01 foram superiores e semelhantes entre si, com 40,16 e 41,36 t ha (p > 0,05). Não houve diferença significativa para a produção de matéria seca, e a média foi de 9,93 t ha (p > 0,05). As silagens mostraram-se semelhantes (p > 0,05) em relação ao pH, Aw e N-NH3/NT, apresentando valores de 3,92; 0,97 e 7,64%, respectivamente. Não foram encontradas diferenças significativas (p > 0,05) em relação à composição bromatológica das silagens dos diferentes genótipos, sendo observados médios de 30,74% de matéria seca; 10,21% para proteína bruta; 58,69% para fibra em detergente neutro e (p > 0,05). A média da digestibilidade da matéria seca foi de 59,90%. Com base no valor nutricional e na digestibilidade das silagens de milheto, os cinco genótipos apresentam-se adequados à produção de silagem com potencial para o norte de Minas Gerais Palavras-chave: digestibilidade, produção de matéria seca, silagem.

“…Torres et al (2008) observaram que, entre sete espécies de cobertura avaliadas, o milheto foi a gramínea com maior produção de fitomassa seca e acúmulo de nitrogênio (N). A produção de forragem do milheto pode variar de 20 a 70 t ha -1 de matéria verde em função da condição de cultivo e época de corte da planta (AMARAL et al, 2008;GUIMARÃES JUNIOR et al, 2009;COSTA et al, 2014).…”

Resumo:A produtividade e a qualidade da matéria seca produzida pelo milheto dependem da época de corte da forrageira e da adubação nitrogenada. Dessa forma, objetivou-se avaliar a produção de matéria seca (MS), o teor e acúmulo de nutrientes e a relação C/N em diferentes estádios fenológicos do milheto em função dos níveis de adubação nitrogenada. O experimento foi conduzido em casa de vegetação na Universidade do Oeste Paulista, em Presidente Prudente-SP, em delineamento inteiramente causalizado, em esquema fatorial 4x4, com quatro repetições. Os fatores consistiram de quatro doses de nitrogênio (0, 50, 100 e 200 kg ha -1 de N) e quatro épocas de corte da parte aérea, assim discriminadas: folha bandeira; emborrachamento; florescimento e grão leitoso. O maior acúmulo de massa seca das plantas de milheto ocorreu nos estádios de florescimento e de grão leitoso, considerando que a produção foi incrementada com a adubação nitrogenada. Objetivando-se a persistência de palhada no solo para a cultura sucessora, recomenda-se o corte das plantas nos estádios de florescimento e grão leitoso, quando há maior relação C/N. A adubação nitrogenada aumenta o teor e o acúmulo de nutrientes na palhada, como, também, aumenta a liberação de nutrientes para a cultura sucessora devido a menor relação C/N da palhada.Palavras-chave: Época de corte. Nutrição. Gramínea tropical. Pastejo. Sistema plantio direto. Abstract:The productivity and quality of dry matter produced by millet depend on when the forage is cut, and the use of nitrogen fertilisation. Accordingly, the aim of this study was to evaluate the production of dry matter (DM), the levels and accumulation of nutrients, and the C to N ratio at different phenological growth stages of the millet for levels of nitrogen fertilisation. The experiment was carried out in a greenhouse at the University of West São Paulo, in Presidente Prudente, in the State of São Paulo, Brazil. The design was completely randomised, in 4 x 4 factorial scheme with four replications. The factors consisted of four rates of nitrogen (0, 50, 100 and 200 kg N ha -1 ) and four periods for cutting the shoots, as follows: flag leaf, boot, flowering and milk stage. The greatest accumulation of dry matter in the millet occurred at the flowering and milk stages, considering that production was increased with nitrogen fertilisation. With the aim of maintaining straw on the ground for the succeeding crop, cutting is recommended at the flowering and milk stages, when there is a higher C to N ratio. Nitrogen fertilisation increases the levels and accumulation of nutrients in the straw, as well as increasing the release of nutrients to the succeeding crop, due to a lower C to N ratio in the straw.
