4. Conclusion
The previous results led to conclude that planting the corn plants under the treatment (I100 × FYM20m) was found to be suitable for
producing high GY and consequently net profit, under either DIS
or SIS.
The treatment I85 ×FYM20m produced relatively high yield
with saving 15% of the applied irrigation water under DIS or SIS
wherever any of the two systems is available. Under limited irrigation
water, I85 × FYM20m treatment accompanied with DIS was
found to be favorable to save 15% of the applied irrigation water
and produced the same GY and consequently net profit.
Under Sebha environmental conditions and similar regions, we
recommend planting corn under the treatment (I100 ×FYM20m)
which was found to be suitable for producing high GY and consequently
net profit, using either DIS or SIS according to their
availability.
