摘要

This study was conducted during five growing seasons from 2004 to 2008 to investigate effects of different irrigation regimes on vegetative growth, fruit yield and quality of Salak apricot trees in?semi-arid climatic?conditions.?There were six irrigation treatments, five of which (S1, S2, S3, S4 and S5) were based on adjustment coefficients of class A pan evaporation (0.50, 0.75, 1.00, 1.25 and 1.50). The other treatment (S6) was regulated deficit irrigation treatment that was irrigated by applying 100% of class A pan evaporation until harvest, but was not irrigated after harvest.?During the experimental years, the lowest values of irrigation water and evapotranspiration were obtained by S6 and S1 treatments, respectively, while the highest values were obtained for the S5 treatment. There were statistically significant vegetative growth differences among the treatments. The highest vegetative growth values were observed for the?S5 and S4 treatments, while the lowest value was observed for the S6.?Yields per tree and per unit crown volume did not show?statistically?significant differences among treatments in all the years studied, while the yield per unit trunk cross-sectional area showed?statisticallysignificant differences among treatments only in 2008. The S1 treatment showed higher yields per unit trunk cross-sectional area and per unit crown volume than other treatments, while S5 treatment showed higher yield per tree than other treatments in all the years studied.?There were no statistically significant fruit quality differences among the treatments.?Consequently, the?S1 treatment is recommended for apricot trees under the experimental conditions.
