Produção da rúcula sob diferentes lâminas de irrigação e substratos na região dos tabuleiros costeiros

Abstract

ABSTRACT

The arugula is a leafy vegetable, whose leaves are mainly consumed in salads, preserving all its nutritional properties. In Brazil its production and consumption are highlighted in the South, Southeast and Northeast regions. The plants depend on factors related to the edaphoclimatic conditions to achieve a good development. Among these factors, we can highlight soil management and water supply in satisfactory quantity and quality. Therefore, the replacement of water to the soil by irrigation, in the right quantity and at the right time, is decisive for the success of the olericulture. Another factor that must be taken into consideration is the substrate to be used, because it improves the chemical, physical and biological characteristics of the soil. In view of this, the objective was to evaluate thesubstrates and irrigation sheets that best fit the development of arugula (Eruca sativa) culture. The adopted design was entirely randomized in a 2 x 5 factorial arrangement, with four repetitions, being the first factor the substrate 1 (soil from the 0-20 cm layer) and Substrate 2 (soil + goat manure + sand (proportion 2:1:1)). The second factor was composed of five irrigation slopes (50, 75, 100, 125 and 150% of Field Capacity (FC)). The arugula variety used was APRECIATTA Broadleaf. The following production components were evaluated: plant height, number of leaves, leaf area and aboveground dry mass at 40 DAT. The results showed that leaves below and above 100% of field capacity negatively affected the development of arugula in both substrates. The arugula plants grown in SUB2 showed higher productivity, and can be recommended for the cultivation of the crop.

Key words: Eruca sativa, waterstress, organic matter.
