Abstract
The experiment was carried out at Research Station of College of Agriculture Engineering University of Baghdad/AL-Jadiriya during 2022-2023 season to study the effect of seed soaking with Moringa leaf extract (MLE) on grain yield and its component of three bread wheat cultivars. A split-plots arrangement according to RCBD was used with three replications. The first factor was bread wheat cultivars (Rasheed, Buhooth 22, Buhooth 10) as a main plots, and the second factor was soaking of wheat seeds with three concentrations (1%, 3%, 5% in addition to 0% tap water as control) as sub-plots. The results showed that cultivar Rasheed gave highest means for number of spikes (388m-2), number of spikelets (23.49 spikelets spike-1), weight of 1000 grain (40.55 g), and grain yield (4.012 t h-1). In addition, the results showed that soak wheat seeds with 3% gave highest means for number of spikelets (23.08 spikelets spike-1), number of grains per spike (51.07 grains spikes-1), weight of 1000 grain (41.71g) and grain yield (4.255 t h-1). The interaction between cultivars and MLE concentrations it was significant in all studied traits except for the number of spikes.
