Características agronômicas e nutricionais do milho adubado com nitrogênio, molibdênio e zinco

Abstract: A adubação é um dos fatores que mais contribui para o aumento da produtividade do milho, podendo influenciar a qualidade dos grãos. Este trabalho foi conduzido num Argissolo Vermelho-Amarelo distrófico, visando avaliar os efeitos da adubação com N, Mo e Zn sobre a produção e qualidade de grãos de milho, sob o aspecto protéico e teor de nutrientes minerais; avaliar a época mais adequada para amostragem e análise foliar de N nas formas de N orgânico, N-NO3- e N total (NO3- + N orgânico) e relacionar a composição… Show more

“…Galrão (1994), in the study of the deficiency correction of Zn in maize, it was observed that the micronutrient content in grains varied little between the treatments (Zn application methods) as in the present study. Ferreira et al (2001) said that the Zn content in grains increased in 7% due to its application in the furrows, while in the present study this increase reached 32%. In this sense, Kanwal et al (2010) in a study with doses of Zn applied to soil in maize crop, verified a significant raise in the content of this micronutrient in maize grains (21.8 to 30.7 mg kg -1 ).…”

“…Na cultura da mamona, não foram encontrados dados de aplicação de N para comparação, porém é comum encontrar aumento de matéria seca em outras culturas de acordo com a aplicação de doses de N em cobertura, como no caso do feijão (Silva et al, 2003) e milho (Ferreira et al, 2001).…”

“…In corn, Ferreira et al (2001) observed that Mo fertilization increased the grain protein content by 3%. According to Marschner (1995), this positive influence of Mo on protein content can be attributed to its influence on the metabolic processes involving N, by increasing nitrate reductase activity and thereby enhancing the incorporation of N in proteins.…”
