Eficiência da fertilização fosfatada e nitrogenada em cultivares de milheto

Abstract: RESUMOObjetivou-se avaliar a produção de massa seca (PMS) da planta inteira, determinar o nitrogênio contido (NC) no tecido da planta, a eficiência de conversão aparente do nitrogênio (ECAN) e a recuperação aparente do nitrogênio (RAN) de cultivares de milheto forrageiro submetidos às fontes de fósforo e doses de nitrogênio. O experimento realizado no ano agrícola de 2008 constou de um fatorial 2 × 3 × 4, em arranjo de blocos completos ao acaso, com quatro repetições. Os tratamentos foram constituídos pelos cu… Show more

“…According to , when increasing doses of some nutrient are added the greatest increase in production occurs in the first dose, and at higher levels it decreases. A similar result to the one found in the present study was observed by Vitor et al (2009) and Silva et al (2014), evaluating elephant grass and millet cultivars, respectively, that were submitted to different doses of nitrogen. Based on the results of the present study, it can be concluded that the morphogenic, structural, and production characteristics and chemical composition of elephant grass 'Carajas' are positively influenced by increased nitrogen dose.…”

“…Increased dried leaves associated with higher post-grazing residual height had higher effects on chemical composition and in situ digestibility of millet than increased plant density or seeding rate. The average DM production using 30 cm of cutting height in our trial (2.24 ton/ha) was like Schwartz et al (2003) and higher than reported for Brum et al (2008), Camargo et al (2009), and Da Silva et al (2014). There were no effects of cutting heights on forage NDF and CP content and DM digestibility.…”

“…Millet has been used in farms as soil cover, due to its high growth rate (SOUZA NETO et al, 2008;HIRATA et al, 2015). However, it could be also used for hay production (ANJUM; CHEEMA, 2016), grain yield (ALENCAR et al, 2015) and grazing (SCHWARTZ et al, 2003;BRUM et al, 2008;MONTAGNER et al, 2008;SCARAVELLI ET AL., 2008;CAMARGO et al, 2009;DA SILVA et al, 2014). In the South of Brazil, millet has been used for grazing during summer (SCHWARTZ et al, 2003) because of increased dry matter availability (RIZO et al, 2004).…”

“…Segundo Silva et al (2014), avaliando a eficiência da fertilização fosfatada e nitrogenada em cultivares de milheto, verificaram que na produção de massa seca entre as fontes de fósforos superfosfato simples e termofosfato aplicadas no primeiro e segundo corte, foi influenciada pelas fontes de fósforo com acréscimo de massa seca quando aplicou-se o superfosfato simples (1.351 kg de MS.ha -1 ), quando comparado à outra fonte de fósforo aplicada. Corroborando com os resultados encontrados nesse experimento, onde o SSP sem micronutrientes apresentou maior desempenho para a massa seca total.…”
