A field experiment was conducted in Basel Abdulla Alkor productive farm - Delta/ Lahj during 2013/2014 and 2014/2015, planting seasons with the aim to study the effects of 3 planting dates. Different results in 3 wheat cultivars on some growth characteristics and yield components under Delta Tabon conditions / Lahj Governorate.
The results obtained indicate an impact the three planting dates had a significant effect on The cultivar Taiz 10 outperformed the rest of the cultivars and recorded the best values for each of the characteristics of plant height (75.36 cm and 80.79 cm), number of tillers/plant (4.33 and 4.09). stem/plant), the height of the spikelet (8.33 and 8.33 cm), and the number of spikelets (16.46 and 13.45 spikes) for the two seasons, respectively, while the Bohuth cultivar outperformed 13 on the rest of the cultivars in terms of seeding (40.22 and 40.11 days) and maturity (72.22 and 72.11 days) for the two seasons, respectively.
There were significant effects of wheat sowing dates on most of the studied characteristics, where the third date recorded the best characteristics in each of the plant height (68.70 cm) in the first season, number of tillers/plant (4.33 and 4.09). Shrub/plant) for the two seasons, spike height (7.89 and 8.00 cm), and number of spikelets (14.08 and 12.63 spikes).
There were no significant effects of the interaction coefficients between cultivars and planting dates in most of the studied characteristics, except for the two characteristics, the number of shoots/ plant in the second season, which were significant. (T3) the largest number of spikes reached (4.17 stems/ plant) and the number of spikelets in the first season, the overlapping treatment (Taiz 10 T3) recorded the largest number of spikelets in the spikelet with differences Significance amounted to (16.57 spikes).
