| Abstract | ||||
| The present study was carried out at the Experimental Farm of Faculty of Agriculture, Minia University, Egypt during two seasons of 2020 and 2021 to study the response of three soybean cultivars to irrigation intervals and planting methods. Irrigation intervals, planting methods, cultivars in addition first and second order of interactions among them had significant effect on most of growth, yield attributes and water relations in both growing seasons. Seed yield feddan-1 was gradually decreased with prolonging irrigation interval from 14 to 28 days in both seasons. The reduction percentages in seed yield feddan-1 as the mean of the two seasons were 23.05 and 49.40% with irrigation by interval of 21 and 28 days compared to interval of 14 days, respectively. The heaviest seed yield feddan-1 was obtained for the planting on ridges compared to terraces. The increase percentages of seed yield due to Giza 111 and Giza 22 almost were 8.00% compared to Crawford in first and second seasons, respectively. About the effect of irrigation intervals x planting methods interaction on seed yield/fed. in both seasons. It could be recommended that irrigation by interval of 14 days with planting on ridges can achieve the heaviest seed yield feddan-1. | ||||
