Alternativas para adubação de porta-enxertos de abacateiro 'quintal' e seu efeito no pegamento de enxertia

Abstract: O abacate é uma fruta de alta expressividade no cenário frutícola brasileiro. Dos fatores limitantes na expansão racional dessa frutífera, destaca-se a dificuldade de obtenção de mudas de alta qualidade. O objetivo deste trabalho foi avaliar a obtenção de porta-enxertos de abacateiro 'Quintal', em condições de telado, com o uso de fertilizante de liberação lenta e solução nutritiva, com diferentes doses de N, P e K. O experimento foi instalado e conduzido no Setor de Fruticultura do Departamento de Agricultura… Show more

“…The adoption of commercial substrates instead of soil and other materials in the production of seedlings demands more fractions or a more frequent application of fertilizers, as a consequence of the susceptibility that these substrates have to leaching-driven nutrient loss (SERRANO et al, 2010). Alternatives such as fertigation and slow-release fertilizers have been used to produce fruit tree rootstocks and seedlings in an attempt to minimize these losses (COSTA et al, 2011;ALMEIDA et al, 2012).…”

“…The use of slow or controlled-release fertilizers has resulted in higher fertilization efficiency in nurseries, in comparison with fertigation and conventional fertilizers (GIRARDI et al, 2010;COSTA et al, 2011;ALMEIDA et al, 2012). However, it is necessary to carry out calibration studies to determine adequate doses for different cultivation conditions of rootstocks and seedlings of several species.…”

“…Associated with a good substrate, Delamerlina et al (2014) recommend the use of quality fertilizers, at adequate doses and with slow release. That slow or controlled-release fertilizers can be used in the fertilization of fruit seedlings, since they promote a synchronism between the release of nutrients and the requirements for plant growth and development, which renders unnecessary the split application of other sources, thus avoiding the occurrence of nutritional deficiency and losses through leaching, which consequently reduces costs with execution (Costa et al, 2011). Among these fertilizers, a prominent one is Osmocote ® , which has been widely employed nowadays in the production of seedlings in containers (Elli et al, 2013).…”

“…Evaluating the influence of various substrates and two fertilizer formulations on the development of yellow passion fruit seedlings, Silva et al (2001) claim that Osmocote ® promoted the greatest development of the seedlings, followed by 4-14-8 NPK. The use of slow-release fertilizer proved to be efficient in the production of seedlings of citrus (Almeida et al, 2012), avocado (Costa et al, 2011), pineapple (Freitas et al, 2011), banana (Rodrigues et al, 2019), papaya (Serrano et al, 2010) and tamarind (Santos et al, 2018). For sugar apple, there is a lack of studies using slow-release fertilizers in different organic substrates.…”
