Crescimento e produção de taro 'Chinês' influenciados por tipos de mudas e camadas de bagaço de cana-de-açúcar

Abstract

Plant growth and yield of 'Chinês' corms taro influenced by propagation methods and sugar-cane mulch

Yield performance of taro (Colocasia esculenta L.) cultivated with topdressing nitrogen rates at the Zona da Mata region of Minas Gerais

“…Positive production response to N application has been reported by other authors with N applied either through organic fertilizer sources or associated with them, such as chicken litter (Heredia Zarate et al, 2003;Oliveira et al, 2008), sugarcane bagasse (Puiatti et al, 1992a;Puiatti et al, 2004) and coffee husk and, sugarcane bagasse and swine manure biofertilizer (Sediyama et al, 2009).…”

Efeito Da Adubação Orgânica, Espaçamento E Tamanho De Rizomasemente Sobre Artrópodes Em Mangarito Xanthosoma Mafaffa Schott

“…A maior quantidade de reservas do material propagativo, provavelmente, propiciou plantas mais vigorosas, com maior número de folhas e com áreas foliares maiores. A área foliar é um importante atributo fisiológico, a qual está associada positivamente com a produção de rizomas de inhame (PUIATTI et al, 2004). Portanto, as plantas derivadas dos rizomas-neto apresentaram uma significativa proporção desses insetos.…”

“…O crescimento da parte aérea do inhame Colocasia esculenta (Araceae) é lento no inicio, onde atinge o máximo de área foliar entre 135 a 165 dias após o plantio, declinando posteriormente (PUIATTI et al, 2004). Ou seja, no início da lavoura, a planta se apresenta com melhor qualidade nutricional de folhas, mas em reduzido número, o que pode torná-la mais susceptível no início do cultivo.…”

Agro-economic yield of taro clones in Brazil, propagated with different types of cuttings, in three crop seasons

“…As it was not used any type of seasoning or of form of fertilization, among the reasons for the obtained variable yields, the environmental changes that normally occur between the growing seasons and that infl uence the ability of phenotypic expression of clones in response to genetic differences between clones and the effect of the type of cuttings used in propagation may be mentioned. Puiatti et al (2004), among the justifi cations for the productive differences of the 'Chinês' clone, in two growing seasons, mentions TYPES OF CUTTINGS FOR AGRO-ECONOMIC YIELD OF TARO CLONES IN BRAZIL that, by being installed at the fi eld in the early period of temperature increments (late winter), plants of experiment II achieved, compared to the fi rst experiment, about 70 days of period with temperatures more propitious to growth. According to Heredia Zárate et al (2002), as the higher yields of fresh and dry weight of corms were obtained with the use of small cuttings, for propagation, it is showed that there is a size limit of the cuttings and that this limit should be related to the amount of peel and fresh weight of these cuttings.…”
