Abstract

This study was conducted to study and utilize some pressurized irrigation systems (drip and micro jet) on the non-traditional of agricultural media (rice straw media) for irrigating the tomatoes plants (super red) and radish crop in the weather of Egypt-Giza. The experiments were carried adding the irrigation water with percentage (50% - 75% & 100%) from water requirement for the plants in doses (one dose, two doses, three doses) for every treatment. Tomatoes was Planted in the rice straw bales on the surface. The radish plants were planted in semi cones shapes from rice straw in pots with the same management of water adding the crops on the rice straw bales. The important results: The productivity of growing crops in rice straw culture was a better than a productivity of plants that grown in sandy soil. All treatments that was watered on 3 batches gave productivity are better than the treatment that watered on 2 batches or 1 batch and the best production was in case of 100% of W. R on 3 doses per day.  The best treatment concerning W.U.E was that watered 3 batches daily and with amount 75% from the water requirement by saving 25% from the water requirements that can be taking part for irrigating other growing areas.
