| Abstract:
The response of a highbush blueberry (Vac. Bluetta) to different levels of water application under microjet or drip irrigation was studied over a period of four years, at the Agricultural Experiment Station of the University of Concepción in Chillán, Chile. With drip and microjet irrigation, fruit yield increased with higher levels of water supply. During the first three years of harvest, plants under drip irrigation produced higher yields compared to those with the microjet system, at all levels of water application. However, microjet surpassed drip irrigation in those treatments with higher levels of water supply during the fourth year of harvest. In this case, the highest yield for microjet irrigation was 8300 kg ha-1, with a level of water replacement of 6100 m3ha-1, compared to 6300 kg ha-1 for drip irrigation. | |
