| Abstract Soil management is a practice that influences the development of fruit trees. In this sense, the objective of this study was to evaluate the effect of different soil cover/mulching types on weed control and on the early development of pear trees Hosui cultvar. The experiment was conducted in two consecutive cycles: 2015/2016 and 2016/2017. Treatments consisted of the following soil covers in pear tree planting rows: natural cover, ryegrass straw intercropped with millet, pine sawdust, shading cover (70%), rice husk, Curauá fiber and weeding. Soil infestation by weeds was evaluated in the spring-summer period for two years, as well as the vegetative pear tree development (plant height and diameter and SPAD chlorophyll index). Managements using... |

| In Brazil, pear production presents the same incipient situation over the last 15 years, due mostly to low production technology. In this context, this study aimed to evaluate the development, growth and production of the pear tree cultivars Cascatense, Tenra and Hosui grafted on 'CPP' quince rootstock, using 'FT' pear as interstem. This trial was carried out in Guarapuava, State of Paraná, Southern region of Brazil, by five productive cycles. The pear trees were planted in September of 2004, spaced at 1.0 x 4.0 m (2,500 trees ha-1), trained to the modified central leader, on a Four-wire trellis, with drip irrigation and cultivated under organic production system. The following variables were evaluated: sprouting, anthesis, yield, fruit weight, soluble... |

| A adubação de plantas frutíferas de clima temperado é rotineiramente recomendada em função da interpretação de laudos de análises químicas de solo e folhas, mas não são específicas para as diferentes cultivares e porta-enxertos. Neste contexto, um experimento foi conduzido durante dois anos, com o objetivo de avaliar o estado nutricional de diferentes cultivares de pereira enxertadas sobre o porta-enxerto marmeleiro 'CP', em Guarapuava-PR. As cultivares de pereira Cascatense, Tenra, Hosui, Packham's Triumph e Williams foram plantadas em 2004, em densidade de 2.500 plantas ha-1. Amostras de folhas e de frutos foram coletadas em 2006 e 2007 para análises químicas dos teores de nutrientes. Folhas completas e normais foram amostradas em meados de janeiro,... |
