Crescimento de cultivares de cenoura em diferentes ambientes

Abstract: A cenoura (Daucus carota) é a quinta hortaliça mais cultivada no Brasil, apresentando produtividade média de apenas 32,1 t ha -1 com potencial produtivo para alcançar 80 t ha -1 . Uma das causas apontadas para esta baixa produtividade é o plantio de cultivares não adaptadas aos ambientes encontrados no Brasil. Sabendo da importância dos efeitos da interação genótipo e ambiente, objetivou-se avaliar o crescimento de cultivares de cenoura no cultivo de outono-inverno em dois municípios com características edafo-… Show more

“…This analysis is based on the fact that, on average, 90% of the organic matter accumulated throughout the plant growth results from the photosynthetic activity and the rest from the mineral absorption from the soil. By means of sequential measures, the dry matter of the plant is quantified, which allows for evaluating the contributions of different organs to the total growth (LESSA et al, 2008;PEDÓ et al, 2014;PEREIRA et al, 2015). The accumulation of macroand micronutrients at 150 DAE in descending order was: N > K > Ca > Mg > S > P and Fe > Zn > Mn > Cu > B, respectively ( Figure 5).…”

“…There are microclimatic differences within the same agricultural zone (Possas et al, 2012). The effects of these microclimatic differences on the performance of a given crop are of great importance; therefore, before making definitive recommendations of genotypes in different locations, it is necessary to verify the performance of the cultivars available for that region (Pereira et al, 2015).…”

“…Silva et al (2017) relataram redução da produtividade comercial da cenoura, cultivar de inverno, com a aplicação de 288 g ha -1 de metribuzin. Repostas diferentes na produtividade comercial de cenoura em ambientes diferentes também foram observadas por Pereira et al (2016) e Pereira et al (2015), na qual os autores afirmam que esta variação ocorreu pelas características distintas de solo onde as plantas de cenoura foram cultivadas.…”
