| 520 | _aThe objective of this research is to study the influence of irrigation discharges and tillage systems on com (zee mays 1.) grain yield and water efficiency with and without mulching rows by rice straw. The experiments were conducted for one season (autumn) during 2003 at Experimental Farm of Agricultural Research Station at Zarzora (Etay El Baroud, Beherah Governorate). Three irrigation discharges (1.5, 2.0 and 3.0 Us) and three tillage systems using chisel, moldboard and rotary plows were used. The experimental site is classified as clayey soil. Irrigation discharges and tillage systems and rows mulching show statistically significant difference in their effects on com grain yield and crop water use efficiency. Generally, the ..result~ revealed that the applied water decreased as the irrigation discharge increased at all tillage systems. The plowing with' moldboard plow recorded the highest amount of consumed water compared to other plows under rows mulching. On the other hand, plowing with the chisel plow gave highest com grain yield compared to moldboard and rotary plows with values of 3.66, 3.78 and 2.95 ton/fed under different irrigation discharges 1.5,2.0 and 3.0 Us respectively with rows mulching. For the irrigation discharge of 2.0 Us, the water use efficiency recorded the highest ratio with values of 1.96, 1.51 and 1.67 kg/m3 for chisel, moldboard, and rotary plows respectively under mulching rows. As a result, the tillage with chisel plow with irrigation discharge 2.0 l/s and mulching rows with rice straw seems to be a promising system for com production in soil containing high colloids ratio between particles and owning high ability to keep water. | ||
