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.
