Abstract

In sports turfgrass the fertilization is constant and at high levels, mainly due to frequent mowing and consequently significant nutrient export. This situation is similar to fertigation, where there is also a need for a more frequent recommendation of fertilization. Currently the fertilization and irrigation recommendation on turfgrass is subjected and is based on the experience of the professionals and on the visual aspect, which greatly increases the chances of error. So there is a need to develop tools and to study the development of the turfgrass to produce information that can give professionals the support to make the correct recommendation. Therefore, this work is aimed to generate technical information that may contribute to the fertilizer and irrigation management and prove or not the possibility of porous cup extractors on turfgrass, which is a widely used technique in fertigation. The research project will be conducted at FCA-UNESP in Botucatu where two irrigation managements, four nitrogen and two potassium rates will be used. The effects of these treatments on the development of the Tifway 419 bermudagrass (Cynodon dactylon X Cynodon transvaalensis) will be analyzed and related with foliar, soil and soil solution analysis to find values that can be used to keep turfgrass quality throughout the year. The experimental design will be randomized block with split plots. During a year the following assessments will be undertaken: soil, foliar and soil solution analysis, and turfgrass quality analyses such as turf height, speed recovery, surface traction and green color intensit.
