EFFECT OF IRON, BORON AND ZINC APPLICATIONS ON YIELD AND QUALITY TRAITS OF SOME SOYBEAN CULTIVARS (Glycine max (L.) Merr.)

This research was conducted in 2019 at Tekirdag Namik Kemal University, Faculty of Agriculture, Field Crops Department, Research and Experimental area. It aimed to determine effect iron, boron zinc applications on yield quality traits some soybean cultivars. The experiment carried out as a split plot design based RCBD with three replications, which cultivars constituted the main (Arısoy, Safir Bravo), micronutrients their combinations sub-plot (control, Fe, B, Zn, Fe+B, Fe+Zn, B+Zn Fe+B+Zn). were applied plant by foliar spraying V3-V5 period. In study height, first pod number per plant, seed pod, 100 weight, yield, oil content crude protein investigated. results showed that significantly increased values for all traits. According findings, changed between 304.93-382.62 kg da-1, 12.51-17.16% 37.82-42.30% wide variation. terms cultivar x micronutrient interaction, highest obtained from Fe+Zn Fe+B+Zn variety (395.01, 393.55 396.42 respectively). content, is most important character soybean, varied 36.79-43.14%, but this difference not found be statistically significant interaction. concluded had positive effects characteristics soybean.
