Épocas de aplicação de nitrogênio em feijoeiro cultivado após milho solteiro ou consorciado com braquiária

Abstract: Resumo -O objetivo deste trabalho foi avaliar a resposta do feijoeiro a épocas de aplicação de N, em sistema plantio direto, após cultivo de milho solteiro ou consorciado com braquiária. O delineamento experimental utilizado foi em blocos ao acaso, com arranjo de parcelas subdivididas e quatro repetições. As parcelas consistiram de: cultivo de milho solteiro ou milho consorciado com braquiária, nas duas safras de verão precedentes à semeadura do feijão. As subparcelas consistiram de: três épocas de aplicação d… Show more

“…Productive traits, such as number of grains per pod and 100-grain mass, showed no significant difference (Table 4), neither for straw types nor for N topdressing splitting, corroborating the results obtained by Soratto et al (2006Soratto et al ( , 2013 Table 4. Number of pods per plant and grains per pod, 100-grain mass and grain yield for the 'IAC Imperador' common bean, as a function of N fertilization in succession to single maize, maize intercropped with brachiaria and single brachiaria, before sowing the common bean.…”

“…The 100-grain weight was not influenced by treatments, which agrees with results found by Crusciol et al (2007), Moreira et al (2013), and Soratto et al (2013). According to Crusciol et al (2007), grain weight of the common bean has a low variation when the grow conditions are changed, due to its high heritability characteristic, which means that this characteristic more heavily depends on the cultivar than on the crop practices adopted.…”

“…Uma opção para aumentar a disponibilidade de N no início do crescimento da cultura do feijão, de forma a minimizar o efeito da imobilização pelos microrganismos, seria a aplicação antecipada do N na pré-semeadura ou na semeadura da cultura (Sá, 1996;Mai et al, 2003;Soratto et al, 2008). Entretanto, altas doses de N no sulco de semeadura podem comprometer o estabelecimento das plantas de feijão (Teixeira et al, 2005;Santos & Fageria, 2007;Alves Junior et al, 2009).…”
