Tsvetanov, E., Koumanov, K., Matev, A. & Prodanova-Marinova, N. (2020). Microsprinkling effect on the microclimate in vine nursery. Bulg. J. Agric. Sci., 26 (3), 540–544
Subject of investigation was the evaporative-cooling effect of microsprinkler irrigation on improving vine production in the nursery. According to the obtained results, microsprinkling reduced the temperature of the aboveground air by 2.1-4.8°C and increased the air relative humidity by 4.4–15.8% on the average. The microsprinkling impact on the grafted cuttings was manifested by average decrease of 1.8°C and 4.2°C in the wax and the leaf temperature respectively. Microsprinkling did not affect the soil-surface temperature, which was dependent on soil moisture – a much more conservative parameter.
