| Abstract | ||||
| The current investigation was carried out at Gemmeiza Agricultural Research Station, Agricultural Research Center, Egypt, during 2021 and 2022 summer seasons to investigate the response of five soybean genotypes (DR 101, H4L4, PI416-937, Giza 35 and Giza 111) to three irrigation intervals (14, 21 and 28 days).The results showed that Giza 111 cultivar was superior over other genotypes at the different irrigation intervals in yield components traits (number of pods and seeds per plant, seed weight plant-1, seed index, seed yield fed-1 and Land use efficiency (L.U.E). Giza 111 irrigated every 14 days was the best treatment; producing the highest seed yield fed-1.Pods, seeds, seed weight plant-1, seed index and Land use efficiency (L.U.E) were significantly higher with the same combination followed by those irrigated every 21 and 28 days. Irrigation every 21and 28days caused reductions in seed yield and its components as compared to irrigation every 14 days. Reduction in seed yield faddan-1 due to prolonging irrigation intervals from 14 (recommended) to 21 and 28 days were 2 and 6 % in Giza 111 cultivar, 9 and 12 % in Giza 35, 8 and 20 % in DR 101, 11 and 17% in H 4L4 and 24 and 28% in PI 416-937. This means that in case of water shortage Giza 111cultivar could be successfully grown under irrigation intervals up to 28 days, recording the highest value of water use efficiency as well as water productivity. | ||||
