Abstract
Two field experiments were conducted at the Agriculture experiments and research station at Giza, Faculty of agriculture, Cairo university, Egypt during 2014 and 2015 seasons. The objectives of this study were to investigate the growth, yield, oil content and its fatty acid as well as protein content and its amino acids of soybean in relation to prevailing climate factors during the growing season. Soybean variety Giza 111 was seeded on five sowing dates (April, May, June, July and August) to obtain varied climate parameters. Delay in sowing date from April to August decreased the growing season duration by two weeks; this was related to high values of maximum temperature (Tmax.), minimum temperature (Tmin), actual sunshine hours (ASSH), accumulated growing degree days (AGDD) and accumulated photo-thermal units (APTU). Delaying sowing date after June decreased leaf area and top dry weight per plant. This was related to low values of ASSH and solar radiation energy (SRE) during the period from emergence (E) to 60-days later .Seed yield and its components were gradually decreased as seeding date was delayed, this was related to the change in diurnal temperature range (DTR), ASSH and SRE prevailed during reproductive growth stage (RGS). Seed oil content was slightly decreased as sowing was delayed from April until July, while the reduction was more obvious for August sowing date; this was related to high daily average temperature (Tav.) DTR, ASSH and APTU-prevailed during RGS
