Determination of yield; agronomic and quality properties of some soybean genotypes in bornova under double crop conditions

The aim of this research was to determine yield and important agronomic and quality of trait some soybean varieties and lines which are grown under double crop conditions in the Bornova IZMIR. The study was conducted at the experimental area of Department of Field Crops, Faculty of Agriculture, Ege University in 2014. In this study, 10 advanced (F9) soybean lines improved by General Directorate of Agricultural Research and Policies (BATEM 223, BDUS-04, KASM-03, KANA, KASM-02, BATEM 207, BATEM 306, BDSA 05, BATEM 317, KAMA) and 4 standard varieties (ARISOY, ATAEM-7, BRAVO, NOVA) were used as plant materials. Field trials were conducted in a randomized complete block design with 4 replications. Sowing date was at 24 June. The seeds inoculated with Bradyrhizobium japonicum bacteria, were sown in June after wheat harvest by hand over 45 plants per square meter. Emergence date was homogenous as on July 4th. In this process, observations were taken according to the desired characteristics and noted. The trial was harvested on October 15 and the blending process was continued. As a result of this research, 22,01% oil ratio was obtained from the promising genotype KASM 03 which has the highest grain yield in current research and BDUS 04 had higher protein ratio (49,23%) among the varieties and other genotypes. KASM 03 (417,83 kg/da), BATEM 317 (403,40 kg/da) and BATEM 306 (388,20 kg/da) lines provided the best result for grain yield while NOVA (97 day), BRAVO (98 day) and ARISOY (100 day) soybean varities and KASM 02 (96,5 day) lines provided the best result in earliness.
