Abstract
Two field experiments were carried out in the Experimental Farm of the Faculty of Agriculture Damanhour, AlexandriaUniversity at El-Boustan region in each of 2003/2004 and 2004/2005 growing seasons. The aim of this investigation was to study the effect of the three late sowing dates (Dec.10th, Dec.20th and Dec.30th ) on productivity of four Egyptian wheat cultivars (Sakha 8, Gemmiza 7 ,Giza 168 and Seds 1) which were sown by the three seeding rates (350,400 and 450 grains /m2).A split –split-plot design with four replicates was used in each experiment. The sowing dates occupied the main plots while both cultivars and seeding rates were arranged in the sub and sub-sub plots , respectively. The results could be summarized as follows:
- The sowing dates had a significant effect on all studied traits, except harvest index in both seasons. The highest values were recorded when the wheat cultivars were sown at Dec.10th.
- Significant differences among wheat cultivars were observed for all studied traits , in both seasons. Giza 168 cultivar surpassed the three other cultivars for all traits, in both seasons.
- All studied traits were significantly affected by seeding rates except spike length and harvest index in the second season and number of spikelets/spike & number of grains /spike, in both seasons.
- The first and second order interactions significantly affected all studied traits in both seasons,except the interaction between sowing dates and seeding rates for harvest index in the second season.
Generally, it could be concluded that sowing Giza 168 wheat cultivar, by 400 grains/m2 with delayed dates on Dec.10th increasing to 450 grains /m2 with more delaying dates until Dec.30th could improve wheat yield under newly cultivated sandy soil conditions
