Response of a long-lived cherry cultivar to contrasting irrigation strategies in the Jerte Valley, Extremadura, Spain
The present paper shows the results of field trials carried out in 2010 and 2011 in a cherry plantation (Prunus avium) with a long-lived cultivar, ('Lapins') in the Jerte Valley (Cáceres, Extremadura, Spain) to study the response contrasting irrigation programs. This work contributed to contrasting irrigation strategies, including pre- and postharvest irrigation. Preharvest irrigation programs included three irrigation treatments covering 100% of the ETc and another using traditional irrigation practices in the area, which include no irrigation during the preharvest interval. Postharvest irrigation programs consisted of four deficit irrigation treatments, three of which replaced 25, 50 and 100% of the ETc and one which delivered the average amount of water supplied during postharvest in the area. The experiment was a random block design with four replications. The study indicates that the deficit controlled treatment of replacing 25% of the ETc postharvest for two consecutive years resulted in superior yields than other treatments. Also, the regime using the average farmer's irrigation water and their habitual irrigation practices only postharvest maintained a good yield similar to that obtained by other regimes, which used preharvest irrigation, getting a reduction in the consumption of water up to 60%.
