The Effects of Copper-Zinc Interactions on Yield and Yield Components in Soilless Grown Beans (Phaseolus Vulgaris L.)

Abstract

This research was conducted under the ecological conditions of Van-Gevas, Turkey in 2015 and 2016 in three replications according to the Random Parcel Trial Pattern. This study is a flowerpotting trial investigating the effects of copper (Cu) and zinc (Zn) doses applied in increasing amounts to the bean plant grown in the hydroponic system. Four different copper doses (0-200-400-800 mg Cu kg(-1)) and four different zinc doses (0-2.5-5.0-10.0 mg Zn kg(-1)) were applied. This study was conducted in drybean varieties on different doses and interactions of Cu and Zn; characteristics such as plant height, number of pods in the plant, number of branches, grain yield in the plant, harvest index and protein ratio were examined. According to the results of the research, while the of 400 mg kg(-1) Cu and 5.0 mg kg(-1) Zn dose applied to Yakutiye-98 variety in the first year increased the seed yield (36.32 g plant(-1)) in the plant; in the second year, 200 mg kg' Cu applied to Yakutiye-98 variety and 5.0 mg kg(-1) Zn increased the yield (28.45 g plant(-1)). In general copper-zinc interaction; Co-administration of Cu and Zn doses led to increases in yield and yield parameters of bean varieties compared to the separate administration of these doses and was found statistically significant at 1% level.
