- Abstract
The objective of this study was to evaluate different irrigation depths in the productivity and quality of cassava for table at different harvesting times in São Mateus, ES. The experiment was completely randomized blocks, in a subdivided plot with four replicates. Treatments consisted of five water levels (T1 - non irrigated treatment, T2 - irrigated treatment with 33% ETc replacement (crop evapotranspiration), T3 - irrigated treatment with 66% ETc replacement, T4 - irrigated treatment with replacement of 100% ETc, and T5 - irrigated treatment with 133% ETc replacement). The subplots consisted of three harvesting times after the emergency; 9 MPE - months post-emergency, 11 MPE, and 13 MPE. The highest table cassava yields were achieved with 130% and 146% of ETc irrigation depths, for total and commercial root respectively, under the edaphoclimatic conditions studied, being the best indication for the northern region of Espirito Santo state. Irrigation depths applications between 101.5% and 118% provided the highest estimates for total and commercial roots per plant, mean diameter and total shoot and commercial root / shoot ratio. Root cooking time was longer with late harvest and increased irrigation depths.
