Abstract
A field experiment was carried out at the field station of the village of Bounouara in Constantine, Algeria, during the agricultural seasons 2016/2017 and 2017/2018, with the aim of studying the impact of four agricultural dates (14th November, 1st December, 2nd January and 17th January). Seven soft wheat varieties (Plateaus, Cedar, Ein ebeid, Arhamocho, Tides, Masin and Pomerzov), according to the design of split plot with three replicates. The results showed that agricultural traits had a significant effect on the phenological stages, plants height and grain yield and its components. The results showed that the decrease in blooming stage in a percentage of 22.52% led to a decrement in plant height (20.81%), number of spikelet (14.02%), number of kernels (12.53%), 1000 kernel weight (10.92%) and grain yield (69.96%). The varieties differed within each other, where the variety Plateaus was the most adaptability and stability one in Bounouara with a grain yield of 4456 Kg/ha. The study recommends taking into consideration the life cycle of wheat varieties when grown, where at the early dates the long-life wheat varieties should be sown, and vice versa.
