In strawberry production, the combination of high productive performance and fruits with desirable physicochemical characteristics requires the use of plants of good quality and high initial vigor. This study aimed to evaluate the effect of plants with different crown diameters on the productive performance and fruit quality of strawberry plants of the cultivar 'Pircinque.' The study was conducted in two evaluation cycles (2016/2017 and 2017/2018). The experimental design was in randomized blocks, with four repetitions, and plots consisting of 20 plants. This study evaluated the crown diameters of plants of 5, 7, 9, 11, 13, 15, 17, and 19 mm. The productivity and number of fruit values increased significantly with larger caliber plants, which also provided precocity of productivity. The use of more vigorous plants also favored the production of fruits with higher soluble solids / titratable acidity ratios and with epidermis coloration closer to intense red. For the cultivar 'Pircinque', the plant crown diameters between 15 and 17 mm are the most favorable because they condition the best productive performances in combination with precocity and good fruit quality.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES The strawberry is extremely demanding as to the physical and soil fertility conditions. The FMAS increase an area of root absorption, allowing greater absorption of water and nutrients, mainly phosphates. The swine wastewater compost and an organic compound concentrated in nutrients, promoting the increase of the pH, the available P and K levels and the soil micronutrients. The general objective of this work is to analyze the influence of different species of AMF and swine wastewater compost no development of neutral day strawberry plants. In this way they have carried out three experiments. The first objective defines efficient arbuscular mycorrhizal fungi for the development of strawberry plants of neutral day cultivars. In the second, the CARS was compared with different substrates formulated from bovine manure and vermicompost in the development of neutral day strawberry plants. The third one evaluated the effect of different AMF species and the application of CARS in the development of neutral day strawberry plants. Arbuscular mycorrhizal fungi have affinity with strawberry plants, especially the genus Acaulospora, which colonizes widely as plants both in the presence and absence of organic compound. The addition of the wastewater compost to soil, in general, provides the development of strawberry plants. The use of CARS as a substrate component raises the contents of the tissues of the plants, and their action is optimized in the presence of mycorrhizal fungi, being equivalent to a mineral fertilization. O morangueiro é extremamente exigente quanto as condições físicas e de fertilidade do solo. Os fungos micorrízicos arbusculares (FMAS) aumentam a área de absorção das raízes, possibilitando maior absorção de água e nutrientes, principalmente de fosfatos. O composto de água residuária de suinocultura (CARS) é um composto orgânico concentrado em nutrientes, promove o aumento do pH, nos teores P e K disponíveis e nos tores de micronutrientes do solo. O objetivo geral deste trabalho foi analisar a influência de diferentes espécies de FMAs e do composto de água residuária de suinocultura no desenvolvimento de plantas de morangueiro de dia neutro. Desse modo foram realizados três experimentos. O primeiro objetivou selecionar fungos micorrízicos arbusculares eficientes para o desenvolvimento de plantas de morangueiro de cultivares de dia neutro. No segundo comparou-se o CARS com diferentes substratos formulados a partir de esterco bovino e vermicomposto no desenvolvimento de plantas de morangueiro de dia neutro. No terceiro avaliou-se o efeito de diferentes espécies de FMAs e da aplicação de CARS no desenvolvimento de plantas de morangueiro de dia neutro. Os fungos micorrízicos arbusculares possuem afinidade com plantas de morangueiro, em especial o gênero Acaulospora que coloniza amplamente as plantas tanto na presença quanto na ausência de composto orgânico. A adição do composto de água residuária em solo, em geral, proporciona bom desenvolvimento das plantas de morangueiro. O uso de CARS como componente de substrato eleva os teores de P nos tecidos das plantas, sendo sua ação otimizada na presença dos fungos micorrízicos, se equivalendo a adubação mineral.
