Improvement of Grain Yield and Protein Ratio in Soybean with Zinc Application
Keywords:Soybean, Grain yield, Grain zinc content, Foliar zinc application, Grain protein content
AbstractIn this study, it was aimed to increase grain yield and grain zinc content by foliar application of zinc in different soybean varieties. In this study, umut-2002, altınay and cinsoy cultivars were used as material and foliar zinc application (0-60 kg ha-1) was applied to these cultivars. In the study, plant height, first pod height, leaf chlorophyll content, number of pods per plant, number of pods per pod, 100-seed weight, grain yield, grain protein content and grain zinc ratio were measured. This increase was also observed in grain protein content and grain zinc content. Among the varieties, the highest grain yield was obtained from the Umut-2002 variety, while the highest protein content was measured from the Altıny variety.
