Abstract:

Two field experiments were conducted at two locations; Turkey and Egypt. Eight recommended spring wheat varieties were planted in 2000/2001 season under two levels of nitrogen fertilizer (70 and 140 kg N/ha) under rain- fed conditions at the experimental farm of the Faculty of Agriculture, Ege University, lzmir, Turkey. In 2000/2001 season, the same varieties in addition to Giza 164 and Sohag 1 were sown under irrigation at the farm of Agriculture Faculty, Minofiya University, Egypt. Nitrogen significantly affected all studied traits except kernels per spike. Genotypes also differed significantly for the studied traits under both nitrogen levels and over N levels and locations. The varieties x nitrogen interaction was significant for all studied traits except plant height and grain yield. A negative grain yield response index (GYRI) for nitrogen under rain- fed (water stress) was obtained. The Turkish Basriby variety gave the highest grain yield under both N levels and either under rain-fed conditions in Turkey or under irrigation in Egypt. Thus, high yielding varieties under irrigation can possibly be adapted to conditions of moisture stress.
