| Abstract | ||
| Throughout the two following winter growing seasons of 2023–2024 and 2024–2025, a field experiment was conducted in the field at the Sakha research station, Wheat Research farm, Field Crops Research Institute, Kafr El-Sheikh, Agricultural Research Center, Egypt. The purpose of this study was to examine the effects of growth stimulants (control, Ascobein, Seaweed, and Molasses) and irrigation level (water amount equivalent to 115, 105, and 95% of field capacity (F.C.) in root zone 0-60 cm depth) on the growth, yield, and grain quality of the wheat cultivar (Giza 171).The findings demonstrated a substantial decrease in the majority of growth characteristics, yield and its attributes, and water consumptive use (WCU) when the irrigation water level was lowered from 115% to 95%. Proline, peroxidase activity, catalase activity, dry gluten, protein content, water productivity applied (PWA), and water usage efficiency (WUE) all showed notable increases during season 2024/2025.Grain yield, biological yield, number of spikes per spike, 1000-kernel weight, number of spikes m-2, and WCU all significantly increased when molasses was added to the soil at 115% F.C. In the meantime, proline content, catalase activity, peroxidase activity protein content, dry gluten, PWA and WUE, all increased with molasses 95% irrigation. In the first winter season, the highest dry gluten was associated with treatments of ascobein and Molasses (12.4 and 12.3%), respectively.Taken together, when there was a water scarcity, the application of molasses performed better than seaweed and ascobein in terms of enhancing wheat output, growth characteristics, and grain quality. | ||
