under fruit trees (El-Mehy and El-Badawy 2017, Figure 3.12b). It could also relay
intercropped with wheat and it could be cultivated as early summer crop after sugar
beet and faba bean. Regarding maize, it could be intercropped with summer tomato,
peanut, and sorghum. Finally, flax could be intercropped with sugar beet and
faba bean.
Using the data published in 2015 by the Ministry of Agriculture and Land
Reclamation in Egypt, they calculated the potential increase in the cultivated area of
these five crops, where the actual area was 1,062,495 hectares under traditional
cultivation and could became 2,043,618 hectares under the suggested intercropping
systems, which represent an increase by 90% of the total cultivated area, compared
to its area in 2015. The production of these extra 90% cultivated area could increase
the edible oil self-sufficiency from 33% to 62% (Zohry and Ouda 2018a).
3.7.5 Summer Forage Production-Consumption Gap
Zohry and Ouda (2018b) calculated the contribution of intercropping systems and
cultivation of three-crop sequences in increasing the cultivated area of summer forage crop, where its production-consumption gap was estimated by 90%. The authors
suggested using two legume forge crops, namely cowpea and fahl clover (a short
season clover variety) to attain double benefits; increase the supply of forage crops
and improve soil fertility. Cultivation of fahl clover as an early winter crop after
maize, rice or sorghum crops and before the following winter crop was suggested.
Furthermore, implementing intercropping systems of cowpea with maize, sunflower, sorghum and under fruit trees was also suggested. Their results indicated
that an increase by 1647% in the cultivated area of both crops could be attained if
intercropping systems and cultivation of three-crop sequences will implemented.
