Crescimento da figueira em três ambientes de cultivo, sob aplicação de biofertilizante bovino via fertirrigação

Abstract

RESUMOObjetivou-se determinar o tipo de ambiente e a dose de biofertilizante bovino aplicado via fertirrigação que proporcione o melhor crescimento da figueira nas condições climáticas do semiárido. Este trabalho foi desenvolvido na área experimental do Instituto Federal do Ceará -IFCE, na Chapada do Apodi, no município de Limoeiro do Norte. O delineamento experimental utilizado foi em blocos completos ao acaso, com quatro repetições. Os tratamentos consistiram da combinação de três tipos de meios de cultivo (ambiente protegido, condução em latada e campo) e cinco níveis de adubação: quatro concentrações de biofertilizante e uma adubação mineral, aplicadas aos 15, 30, 45, 60, 75 e 90 dias após poda de condução (Dias Após Poda). Durante a condução do experimento foram avaliados por método não destrutivo, a contagem do número de folhas, o diâmetro caulinar, a altura da planta e o comprimento mé-dio dos ramos. Evidenciou-se diferença significativa entre os ambientes estudados, sendo que o ambiente protegido proporcionou maior desenvolvimento na cultura da figueira, seguido pela condução da cultura em Latada e pelo cultivo em campo, respectivamente. Já em relação às concentrações de adubação com o biofertilizante bovino e com adubação mineral não obtiveram resultados significativos.

Phenology and Yield of the ‘Roxo De Valinhos’ Fig Cultivar in Western Potiguar

“…Yet, the values reported by Celedonio et al (2013) for the region of Limoeiro do Norte-CE, evaluating fig plants in three cultivation environments, show that plants at the field level showed 44 leaves at 90 days of evaluation.…”

“…With increasing numbers of evaluations, there was a steady increase of 0.0134 cm day -1 , with an average of 1.22 m branch -1 across 91 days. According to Celedonio et al (2013), the vegetative development of the crop depends on the absorption and processing of water, energy, CO 2 , and soil nutrients. Figure 2 shows that branch diameter was highest at 63 days of evaluation (21.13 mm), indicating maximum growth rate, being of 21.13 mm; taking into account the initial diameter of the branches, there was an increase of 27.35%.…”

“…Of the fig-producing states in Brazil, Rio Grande do Sul has a harvest area of 1,573 ha, followed by São Paulo (546 ha) and Minas Gerais (497 ha) (IBGE, 2016). According to the Brazilian Institute of Geography and Statistics (2014) In addition to the traditional fruit trees, new species are important as a means of production diversification for temperate crops, and using fig, for its adaptation skills, may be one such alternative according to previous studies in the Brazilian northeast (CELEDONIO et al, 2013). Chagas et al (2012) report that there is not yet a large number of rustic cultivars with good adaptation to tropical regions; thus, studies on the phenology (growth and development) of temperate crops and their adaptations to conditions of warmer regions are of paramount importance.…”

Quality of dwarf cashew tree seedlings as a result of methods for breaking dormancy, container volume and application of bovine biofertilizer

“…The increase in most of the analyzed variables may have been due to the improvement in the substrate composition, increasing the aeration of the substrate and allowing greater root growth; as a consequence, there was greater transport of water and mineral salts to the seedlings. In addition, some farmers have observed the effects of bovine biofertilizer on protecting plant roots from soil pathogens, improving soil fertility and increasing crop yield (Khaled and Fawy, 2011;Celedonio et al, 2013).…”

“…The maximum dose of bovine biofertilizer may have resulted in a higher nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and micronutrient composition (Celedonio et al, 2013), which induced greater cell division and leaf expansion.…”
