Abstract
A two-year field experiment (1997 and 1998) was carried out to study rusts infection and growth aspects for wheat cultivars (Giza 157 and 161, Gemmiza 1 and Sakha 8 and 69) as affected by sowing dates (5 and 20 November in addition to 5 December). Sowing date resulted in significant effects for all studied characters, except for leaf rust, in 1997, spike length and number of grains / spike over the two seasons. Rusts infection had the lowest records with the earlier sowing date (5/11) in both seasons. The intermediate date of sowing (20/11) exhibited the highest grain yield/ha., number of spikes m-2 and 100-kernel weight (averaged out 0.14 and 0.44g compared to early and late sowing, respectively). Differences among cultivars were significant for all studied characters, except for 100-kernel weight. Giza 161 cv. highly responded to rusts (29.52 and 51.82% for leaf and stem rusts, respectively) and produced the lowest grain yield/ha (4.47 t). Gemmiza 1 was exposed to lesser leaf and moderate stem rusts infection (5.1 and 19.2% for leaf and stem rusts, respectively as averages of both seasons) and gave the maximum records for spike length and number of grains/spike. Sakha 8 suprassed all cultivars in grain yield/ha. (7.29 t) and number of spikes m-2 (408.74) as averages of both seasons. Sowing date x cultivar interaction was significant for leaf rust (in 1998) and stem rust in addition to grain yield/ha. over the two seasons. Giza 161 was highly reacted to leaf (58.33%) and stem (64.54%) rusts for early sowing dates, respectively. On the other hand, Sakha 8 produced the highest grain yield (7.93 t/ha.) with the intermediate (20/11) sowing date.
