4.3.3.3 Application of Deficit Irrigation
Previous research done on the effect of deficit irrigation on sugar beet yield indicated that saving 27% of the applied irrigation water under surface irrigation resulted
in 14% losses in its yield (Eid and Ibrahim 2010). Whereas, in sandy soil, Mehanna
et al. (2017) and El-Darder et al. (2017) revealed that 23–33% saving in the applied
water could reduce sugar beet yield 7–18%. Thus, we assumed that saving of 11%
of the applied water in the old lands will result in 5% yield losses and saving of 7%
of the applied water in the new lands will result in 6% yield losses.
Table 4.11 revealed that 36.7 thousand hectares can be added if we invest the
saved irrigation water amounts from deficit irrigation application in cultivating new
areas, which will increase the total cultivated area of sugar beet to 239.9 thousand
