Desenvolvimento e produção de frutas de morangueiro cultivar camarosa em substrato alternativo sob diferentes densidades de plantio

Abstract

Strawberry culture is economically important because its fruits are widely consumed in natura, in unprocessed and processed forms, by a variety of industries. Currently the semi-hydroponic cultivation of this crop has been gaining space in relation to soil cultivation, which makes it important to identify, through studies, different systems, cultivation sites, as well as the use of different substrates. The objective of this study was to analyze the agronomic response of Camarosa strawberry cultivar in an out-of-soil system with the use of alternative substrates at different densities. The experiment was carried out in Pelotas-RS, in the locality of Monte Bonito (31°39'44''S, 52°27'29''W at 52.46 m altitude). The experimental design was completely randomized in a subdivided plots scheme, with three replications. In the main plots were allocated three substrates composed of carbonized rice hull, organic compost and tungue pie, and in the subplots, the planting densities of 9, 10, 12, 16 and 20 m-2 plants were allocated. The vegetative growth and the fruit production of the Camarosa cultivar were evaluated. It can be concluded that the addition of organic compound and tungue pie to the carbonized rice hull favors the development of the plants, the production and size of strawberry fruits in the semihydroponic system adopted. The density of 20 plants m-2 confers higher productivity for the cultivar Camarosa.

Planting Density Interferes with Strawberry Production Efficiency in Southern Brazil

“…Usually, the increase in planting density and the reduction of spacing between plants lead to a reduction in the proportional partition of dry and fresh matter for the fruits and, consequently, the reduction in the number of fruits harvested and the individual production of the plants, as verified in the present study (Figure 2A,B). They also point out that the decrease in spacing between plants reduces leaf expansion and provides higher shading, which causes a reduction in solar radiation interception and consequently affects the production of photoassimilate by the plant [55].…”
