Análise Econômica Do Milho Em Sucessão a Diferentes Adubos Verdes, Manejos Do Solo E Doses De Nitrogênio

Abstract: RESUMO:Tecnologias que aumentam a produtividade das culturas são viáveis quando proporcionam lucratividade ao produtor. O objetivo deste trabalho foi avaliar os custos de produção e a lucratividade do milho irrigado, em diferentes sistemas de produção no cerrado. O trabalho foi conduzido em Selvíria (MS), nos anos 2009/10 e 2010/11. O delineamento experimental foi disposto em blocos ao acaso com quatro repetições, em esquema misto com faixas e fatorial. Foram estabelecidos 36 tratamentos, sendo três adubos ver… Show more

“…This suggests that the biostimulant application, even in the treatments with greater volume employed, participates as little importance factor in the productive process. Maize cultivation, as well as other grass species, is highly influenced by cultural practices, mainly by the application of fertilizers, which culminates in higher production costs (Souza et al 2012;Kappes et al 2015). In this context, the value applied to the purchase of the biostimulant is not significant, corroborating with the results obtained for the sweet maize crop, in which the application of 28.00 ml kg -1 of seeds resulted in an increase of 1.50% on the TOC (Jesus et al 2016).…”

“…The use of methodologies that point to the viability of a certain technology use is essential, since the results are used, among other factors, as a basis for the decision-making of the producers (Mwangi and Kariuki 2015). This applies not only to technologies already employed, as fertilizers, for example, which are a significant part of the composition of productive costs (Kappes et al 2015), but also to emerging technologies, among which are biostimulating products (Jesus et al 2016;Vendruscolo et al 2018).…”

“…Legumes form symbiotic associations with N-fixing bacteria, performing biological nitrogen fixation, and present low C/N ratio, which may favor rapid decomposition and mineralization, with significant N contribution to the soil system , which may lead to reductions in N rates in corn (Kappes et al, 2015). Grasses, on the other hand, can soften N losses, promoting their recycling and longer soil cover due to their high C/N ratio (Perin et al, 2004).…”

“…The study of production costs provides important information for decision taking, allowing the choice of the best resources in terms of types of topdressing nitrogen fertilizers be used, and aiming at better results of grain yields and financial return in the corn crop (SOUZA et al 2012). Knowledge of the cost of production of nitrogen topdressing fertilizers covered in corn provides information for the adoption of different technological levels and expands the range of more sustainable and profitable technologies (KAPPES et al 2015). With a view to increasing the efficiency of nitrogen fertilization, reduction in environmental contamination and production costs, and even increasing crop productivity rates, the proper use of nitrogen fertilization is of paramount importance (FAGERIA et al 2007).…”
