Arranjo de plantas na expressão dos componentes da produtividade de grãos de canola

Abstract: Resumo -O objetivo deste trabalho foi avaliar os efeitos do arranjo de plantas nos componentes diretos da produtividade de grãos e na produção final em canola, com uso de híbridos de diferentes ciclos de desenvolvimento. Foram realizados três experimentos com espaçamento entre linhas de 0,20, 0,40 e 0,60 m, em delineamento experimental de blocos ao acaso, com quatro repetições para cada ano de cultivo (2008 e 2009), genótipo (Hyola 432 e Hyola 61) e densidade de plantas (20, 40, 60 e 80 plantas por metro quadr… Show more

“…The assessment of productivity was given by the total manual harvest of each treatment sample and converted into kg ha -1 according to Krüger et al (2011). The economic return of each treatment was achieved by verifying variable costs (employed inputs and labor) added to the capital cost (depreciation of improvements, machinery, equipment and land remuneration), subtracted from the gross revenue, which is obtained by means of grain revenue (Carvalho 2011;Souza et al 2012).…”

“…Portanto, a expressão de potenciais de rendimento da aveia branca está associadà as técnicas de manejo, entre elas, a população de plantas, disponibilidade de nutrientes, controle fitossanitário e outros [1,2]. A máxima exploração do potencial genético de uma cultivar está relacionada ao melhor aproveitamento dos estímulos ambientais, sugerindo que o ajuste da densidade de semeadura se traduz numa eficiente alternativa em promover a produtividade vegetal [6].…”

“…In Paraná state, the crop's second largest national producer (Conab, 2016), canola has emerged as an excellent cost-effective alternative for winter cultivation, with potential to replace wheat (Árrua et al, 2014) because of its advantageous prices and climate conditions. The southern region is considered to be the coldest in the country (Krüger et al, 2011). Besides being an adequate succession with soybean cultivation, canola can also be use as mulching (Kaefer et al, 2014).…”

“…Information on spacing arrangements between lines that can promote both yield and canola seeds' quality in the northwest region of Paraná state is scarce. Farmers have adopted other species' cultivation practices (Krüger et al, 2011;Jacob Junior et al, 2012;Bandeira et al, 2013).…”
