Some suggestions for amount and timing of irrigations are presented in Table 1. This is not to say that it is the only time in the life of the crop that moisture stress reduces yield. It is, however, the time when stress has the greatest effect. Drought tolerance - Drought tolerance is an indication of a crops ability to withstand short periods of drought without significantly reducing yield. We have classified vegetable for drought tolerance in Table 1.
Most vegetables respond to water deficit with reduced yield and quality.
However, most crops also express this stress with growth abnormalities, these are listed in Table 1. Vegetable Irrigation Needs, Critical Moisture Periods, Drought Tolerance, Rooting Depth, and Concerns. Flood Table 1, Part 2.
