Effect of watertable depth and waterlogging on crop yield

A dynamic impact assessment method for rainstorm waterlogging using land-use data

“…Figure 2 shows that the number of simulation points with an error of less than 250 m is 53, while the total number of verification points is 72; thus, the accuracy of this simulation is calculated to be 74%. Most previous studies (Cavazza and Pisa 1988;Vretare et al 2001;Yin et al 2015) have been verified with respect to the maximum water depth. The main reason for taking this approach is that disaster data are usually collected only from locations where disasters occur, such as a road or the intersection of two roads.…”

Estimating the contribution of rainfall, irrigation and upward soil water flux to crop water requirements of a maize agroecosystem in the Lombardy plain

“…With a water table depth of 0.5 m several authors found groundwater contributions around 40% of the crop water requirements and an increase in yield (Follett et al, 1974;Cavazza and Pisa, 1988;Pisa and Ventura, 1991). The same contribution was observed by Kahlown et al (2005) for maize in an arid region of Pakistan.…”

Water table management effects on photosynthesis, chlorophyll, crop yield, and water quality

“…They found optimum yield with a water Kanwar et al (1983Kanwar et al ( , 1984 found that inadequate drainage of heavy soil reduced crop yield by about one-third of the potential yield. Cavazza and Pisa (1988) found the maximum yield of wheat with a 1.25 m water table depth.…”
