| Abstract | ||||
| Two field experiments were conducted at El Karda experimental research station, kafr El Sheikh governorate, Water Management and Irrigation System Research Institute, National Water Research Center, Egypt during two seasons of 2012/2013 and 2013/2014 to study the effect of planting methods and irrigation treatments on yield of wheat and irrigation water management. Experiment laid out in strip plot design with three replicates. Main plots devoted to planting methods as assigned to six planting methods; Flat broadcasting (FB), Flat Drill (FD), Flat Hill (FH), Bed broadcasting (BB), Bed Drill (BD), and Bed Hill (BH), the sub plots were three levels of irrigation water applied; Calculation of water applied according to soil depth 0-20 cm as root length to reach soil moisture before irrigation to field capacity (I1), Calculation of water applied according to soil depth 0-40 cm as root length to reach soil moisture before irrigation to field capacity (I2), and Calculation of water applied according to soil depth 0-60 cm as root length to reach soil moisture before irrigation to field capacity (I3). The important results that obtained from present work were as follows:- Planting methods had non-significant effect on grain yield in the first season and a highly significant effect in the second season. Also, irrigation levels had non-significant effect and interaction between both Planting methods and irrigation levels in both seasons.- Planting methods had a significant effect on straw yield in first season, and a highly significant effect in second season, and irrigation levels had non-significant effect, and the interaction between planting method and Irrigation levels in both seasons.-Flat broadcasting with calculation of water applied according to soil depth 0-60 cm as root length to reach soil moisture before irrigation to field capacity had the highest value of seasonal water applied in the first and second season. While, the lowest value of seasonal water applied recorded with bed drill with calculation of water applied according to soil depth 0-20 cm as root length to reach soil moisture before irrigation to field capacity.-The highest average value of water saving was obtained with bed drill and bed hill with calculation of water applied according to soil depth 0-20 cm as root length to reach soil moisture before irrigation to field capacity, and the lowest value was obtained with flat drill and flat hill with calculation of water applied according to soil depth 0-60 cm as root length to reach soil moisture before irrigation to field capacity.-The highest value of water consumptive use was recorded under flat broadcasting with calculation of water applied according to soil depth 0-60 cm as root length to reach soil moisture before irrigation to field capacity, while the lowest value was recorded under flat broadcasting with calculation of water applied according to soil depth 0-20 cm as root length to reach soil moisture before irrigation to field capacity.-Bed drill and bed hill under calculation of water applied according to soil depth 0-20 cm as root length to reach soil moisture before irrigation to field capacity recorded the highest mean values of irrigation water productivity in the two growing seasons.-Bed hill with calculation of water applied according to soil depth 0-20 cm as root length to reach soil moisture before irrigation to field capacity recorded the maximum value of water productivity in the first and second seasons, while the minimum value of water productivity was obtained with Flat broadcasting under calculation of water applied according to soil depth 0-60 cm as root length to reach soil moisture before irrigation to field capacity in the first and second seasons. | ||||
