Diferentes espaçamentos de plantio e níveis de adubação sobre a atividade da redutase do nitrato em folhas do híbrido de mamoeiro UENF/CALIMAN-01

Abstract: O objetivo deste trabalho foi avaliar o efeito de diferentes espaçamentos de plantio e de níveis de adubação NPK sobre a atividade da redutase do nitrato (RN) nas folhas do híbrido de mamoeiro UENF/CALIMAN-01 , visando a sugerir possível ajuste em seu manejo de adubação nitrogenada, no sentido de maximizar a eficiência do uso do nitrogênio. O experimento foi conduzido na fazenda Caliman Agrícola S.A., no município de Linhares - ES. Utilizou-se o delineamento estatístico experimental em blocos casualizados, com… Show more

“…Double spacing presented LAI nearly 10% higher than single spacing. In addition, Fontes et al (2010), in a study about different planting spacing for papaya (pawpaw) cv. Caliman-01, reported a higher activity for nitrate reductase enzyme (the most important enzyme for plant N assimilation) for plants under double spacing, which could increase N use and LAI, since N enhances plant photosynthetic rate and biomass production (Cavalcante et al 2012).…”

“…introduction Papaya (Carica papaya L.) is a popular fruit species native to tropical America widely grown in Brazil, the second main world producer country with 1.582.638 t in 2013, harvested in 31.310 ha (FAO 2015) Fertilizing management is one of the most important agronomic practices for papaya because it is a continuously growing plant, which produces fruits all the year, thus a high regular nutrient supply is necessary to sustain plant growth and fruit production (Fontes et al 2010;Santos et al 2014).…”

“…Formosa papaya is a plant that absorbs large amounts of nutrients and has continuous requirements, especially during its first year, reaching the maximum point twelve months after transplantation (Fontes et al, 2010). The characteristics of intermittent harvest of papaya causes the plant to require water and nutrient supplies in frequent intervals, thus allowing the continuous flow of flower and fruit production (Brito Neto et al, 2011).…”
