5.3.4 Water Productivity of Winter Tomato Under the Studied
Practices
Table 5.13 presented water productivity of winter tomato under the five studied
production alternatives. The total production of winter tomato under traditional cultivation, as well as under raised beds cultivation and deficit irrigation application
with added new areas will be produced using the same amount of applied irrigation
water under traditional cultivation.
The results in Table 5.13 showed that the traditional cultivation attained the lowest value of winter tomato water productivity, namely 6.8 kg/ha. The highest water
productivity values were attained under application of deficit irrigation and the
saved water will be used to cultivate new areas to increase total production of winter
tomato. In Gharbia, and Demietta governorates, low water productivity existed as a
result of low cultivated area in the old lands. In Port Said and New Valley governorates, there was no difference between the values of water productivity under traditional cultivation, and when raised beds cultivation was applied, either under taking
into account added area or without taking it into account. This result attributed to no
cultivated area in the old lands. Furthermore, the highest water productivity in
Lower Egypt on national level was attained in Menoufia governorate as a result of
high productivity per hectare in the old lands.
It can be also noticed from the table that the values of water productivity in North
Sinai and South Sinai are similar under the five production alternatives, either cultivation on raised beds or application of deficit irrigation. This is attributed to the soil
of these two governorates are sandy and its source of irrigation is groundwater.
Thus, these two water saving techniques were not applied.
5.4 Conclusion
Deficit irrigation application to onion and winter tomato grown on raised beds
allowed saving large amounts of irrigation water. This amount could be used to
increase the cultivated area of another crop has production-consumption gap. The
results showed that cultivation on raised beds and application of deficit irrigation to
onion resulted in increasing its total production by 11 and 6%, respectively. With
respect to tomato, cultivation on raised beds and application of deficit irrigation
resulted in increasing its total production by 6 and 1%, respectively. In both crops,
application of deficit irrigation on raised beds resulted in higher water productivity
value than the value obtained under traditional cultivation.
