Second crop potential of soybean lines for Diyarbakır location on the yield and quality

The importance of vegetable oils and oilseeds, which have an important role in human nutrition and many branches of industry, is increasing day by day. Soybean is one of the most important industrial plants in the world. Despite having the most suitable agricultural land to cultivate soybean, Turkey meets through imports almost all of its soybean needs. The aim of this study is to determine the suitability of soybean genotypes as second crop production for Diyarbakir conditions. In this study, KA-04.03.07, KA-04.06.01, KKMA-118, KSA-26, S-02.14.11, S-03.03.7, Sa-01.08.15 advance lines and Arisoy, Blaze, SA-88 Bravo, Ataem-7, Umut-2002 and GAPSOY-16 varieties were used as materials. According to the results of the research, average grain yield of genotypes was 2,37 t/ha and highest grain yield was obtained from GAPSOY-16 (4,00 t/ha) variety, followed by S-03.03.7 line (3.66 t/ha). The lowest grain yield value was obtained from Umut-2002 (1,33 t/ha) variety. As a result of the correlation analysis, a positive and significant relationship was found between grain yield and thousand grain weight. It is concluded that GAPSOY-16 variety and S-03.03.7 line can be successfully grown as second crop in Diyarbakir province.
