Resumo: The objective of this study was to evaluate the effects of different organic fertilization treatments on maize grain productivity and nitrogen fractions in semi-arid NE Brazil. The experimental plots were established in a Entissol in randomized blocks in a factorial design (2 x 3) + 2 that included two methods of fertilizer application (surface applied or incorporated) and three types of organic fertilization (15 t.ha-1 of animal manure, 15 t.ha-1 of Gliricidia sepium prunings, 15 t.ha-1 of Croton sonderianus prunings) and control plots without fertilization). The method of application and the three types of organic fertilizer had different effects on maize grain productivity and nutrition. For example, all types of organic fertilizers, when surface applied, significantly increased maize grain productivity and N concentration. Maize leaf N content was greater after surface application of G. sepium prunings. Surface application of manure increased leaf P concentration, but leaf K was greater after incorporation of C. sonderianus prunings. Maize leaf N fractions were inversely related to grain productivity.

O milho foi cultivado em um Neossolo Flúvico em parcelas distribuídas em blocos ao acaso com quatro repetições e oito tratamentos arranjados em esquema fatorial (2 x 3) + 2, incluindo dois métodos de aplicação dos adubos (incorporado ou em superfície) e quatro tipos de adubação (15 t.ha-1 de biomassa de gliricidia, 15 t.ha-1 de biomassa de marmeleiro, 15 t.ha-1 de esterco) e parcelas controle sem adubação. Os adubos orgânicos e os modos de aplicação ao solo influenciaram de forma diferente a produtividade de grãos e a nutrição do milho. Os três tipos de adubos, quando aplicados em superfície, incrementaram produtividade de grãos e os teores de N nos grãos. O teor maior de N foliar foi maior na gliricidia em superfície. O teor de N solúvel foliar incrementou com o controle e marmeleiro incorporados e gliricidia aplicada em superfície. O esterco em superfície incrementou o teor de P foliar, enquanto o K com o marmeleiro incorporado ao solo. As frações nitrogenadas no tecido foliar não acompanharam a tendência da produtividade de grãos, ou seja, os tratamentos que proporcionaram as maiores produtividades de grãos apresentaram as menores frações nitrogenadas.UEL2011-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/527110.5433/1679-0359.2011v32n4Sup1p1735Semina: Ciências Agrárias; Vol. 32 No. 4Sup1 (2011); 1735-1744Semina: Ciências Agrárias; v. 32 n. 4Sup1 (2011); 1735-17441679-03591676-546Xreponame:Semina.
