Abstract
Abstract To maintain the quality of a lawn and allow it to perform its functions (esthetics, enhancement of property, reduction of air temperature, etc.) efficient use of irrigation and adequate fertilization are necessary. The use of wastewater from sewage treatment, which has a nutrient load, in irrigation, can be an alternative especially if applied via subsurface, to reduce contamination risks. This study was conducted to examine the development and quality of an ornamental lawn of Zoysia japonica Steud (zoysiagrass) irrigated with wastewater depths, by two methods. The experiment was carried out in Botucatu-SP, Brazil, during winter and spring (June to December 2016). The treatments consisted of two irrigation methods (sprinkling and subsurface drip) and four domestic-wastewater irrigation depths (50%, 100%, 150% and 200% of the average daily evapotranspiration) plus control, where treated water was supplied by the Basic Sanitation Company of São Paulo State (Sabesp) of Botucatu, SP, Brazil, replacing 100% of average daily evapotranspiration. The following characteristics were studied: clipping dry matter weight, relative chlorophyll content, lawn height, total coliforms and Escherichia coli in the plant tissue and nutrient concentration in the leaves. Subsurface drip irrigation with wastewater, using an irrigation depth of 100% of the average evapotranspiration, allowed an adequate development of the zoysiagrass lawn by maintaining its quality, without contamination by total coliforms or Escherichia coli.
Highlights
Among various existing grass species and cultivars, zoysiagrass (Zoysia japonica Steud) is the most widely sold and recommended for residential areas in Brazil
The aim of this study was to evaluate the development of a Zoysia japonica lawn fertigated with domesticwastewater irrigation depths by two methods, as an alternative for the proper use of domestic wastewater
Clippings dry matter weight The irrigation methods influenced dry matter weight on the first three evaluations, with higher values obtained with subsurface drip irrigation compared with sprinkling (Table 2)
Summary
Among various existing grass species and cultivars, zoysiagrass (Zoysia japonica Steud) is the most widely sold and recommended for residential areas in Brazil. To maintain lawn quality, efficient irrigation as well as adequate fertilization are necessary. Irrigated grassy areas are mostly serviced by sprinklers, especially the retractable type, which does not compromise the esthetics and allows free transit over the lawn; as well as by mechanized mowers. Significant losses may occur due to runoff, drift and evaporation (Abed El-Bast et al, 2016). When using a subsurface drip system, water is applied directly to the root zone, avoiding these problems (Leinauer and Devitt, 2013). There is, a risk of emitters getting clogged (Silva et al, 2017), mainly when wastewater is used
