Abstract

With this work, the objective was to study the Water Stress Daily Index (WSDI) of batatal grass to establish a value that determines the ideal time for irrigation. They were evaluated environmental weather data, water stress index plant using the infrared thermometer and water potential in the soil. The research was conducted in the experimental area of the Department of Engineering and Mathematical Sciences FCAV / UNESP Jaboticabal Campus, in the winter period of 2019. An experiment was installed containing two treatments: T1 - without irrigation, T2 - irrigation performed according to the sum of the culture evaporation and irrigated when the available water capacity of the soil reached 50% and T3 - irrigation performed according to the sum of the culture evaporation keeping the soil always at field capacity. They were made 16 readings in each treatment by measuring the temperature of the vegetation cover and air temperature, held near solar noon, with the use of infrared thermometer. The analysis were performed on the spot. According to the results, the average value of the WSDI is 8.8 °C, to irrigate the T2 treatment.
