Nitrogen fertilization of fall panicum cultivars (Panicum dichotomiflorum Michx.): biochemical and agronomical aspects

Abstract: Information on improved fall panicum cultivars and agronomical pratices is scarce because of the relatively small importance of this crop in Brazil. The present study aimed to evaluate levels of nitrogen sidedressing on plant development and biochemical characteristics of two fall panicum cultivars. The experiment was set up under plastic tunnel conditions in Botucatu, São Paulo, Brazil, with plants growing inside asbestos-cement boxes. The experimental design was a randomized block setup and treatments consis… Show more

“…Furthermore, working with application times and N levels in the millet culture, Soratto et al (2007) found that regardless of the time (14 and 28 DAE), N application increased plant height. The same observation found by Soratto et al (2004).As for stem diameter, similarly to plant height, the highest value was observed in the treatment with N application at 45 DAE, which did not differ significantly from treatment with N topdressing at 30 DAE. Comparing rates of N, Figure 2 shows a linear increase in plant height, stem diameter, dry matter production and N accumulation in shoots of millet with the increase in N levels.…”

“…According to Simili et al (2008), variability in crop management and environmental conditions associated with complex dynamics of N in soil (mineralization/immobilization, volatilization, leaching and denitrification) can cause major changes in its availability to plants (RAMBO et al, 2004). Soratto et al (2004) observed an increase in plant height, number of stems per plant and grain yield while studying N topdressing in millet culture in greenhouse. On the other hand, at field level, Soratto et al (2007) while studying four N rates and two application times, observed that topdressing increased plant height, panicle length and consequently millet grain yield.…”

“…Soratto et al (2004) observaram aumentos na altura da planta, número de colmos por planta e produtividade de grãos de dois cultivares de painço em função da aplicação de N em cobertura sob condições de casa de vegetação. Soratto et al (2007) também obtiveram incremento não crescimento e produtividade da cultura do painço, mediante aplicação de N em cobertura em condições de campo.…”

“…Em condições de casa-de-vegetação, foi observado aumento na altura da planta, número de colmos por planta e produtividade de grãos de dois cultivares de painço em função da aplicação de N em cobertura (SORATTO et al, 2004). Contudo, há carência de resultados experimentais com relação à doses e épocas de aplicação de N em cobertura, em condições de campo.…”
