- Abstract
The need to diversify agricultural production has fostered the cultivation of several crops under environmental conditions atypical to their origin, justifying the extreme importance of studies on the agricultural management of crops in semiarid regions. In this context, this study aimed to evaluate the effects of irrigation depth and potassium doses on fig quality under semiarid conditions. The experiment was conducted in a 4 × 4 split-split-plot design, in randomized block design, with three replicates. The plots corresponded to four irrigation levels (50%, 75%, 100%, and 125% ETc), the subplots consisted of four potassium doses (0, 60, 120, and 240 g K2O plant−1), and the sub-subplot corresponded to the crop years (2018/19 and 2019/20). Results showed that water deficit reduced fig productivity, and the irrigation levels equal to or greater than 100% ETc performed cumulatively throughout the growing cycles. Therefore, irrigation depths from 85.19% to 95.16% ETc are recommended for greater water-use efficiency and fruit quality. Furthermore, potassium fertilization mitigated water stress in fig plants, allowing for reduced irrigation levels, especially in the second year, without compromising fruit traits.
