Effect of Zinc on Some Grain Quality Parameters in Bread and Durum Wheat Cultivars

Abstract

This research was conducted in Isparta, Turkey ecological condition to investigate the effects of different zinc application doses on some quality parameters of bread (Gün-91, Altay-2000) and durum (Kızıltan-91, Kunduru-1149) wheat cultivars. The experiment was set up with three replications according to the randomized complete block design with a split-plot design. The cultivars took place in the main plots whereas the zinc application doses (0, 9, 18, 27 and 36 kg ha -1 Zn) were in the sub-plots. Phosphorus and nitrogen fertilizers providing 40 kg ha -1 of P 2 O 5 and 80 kg ha -1 of N were applied to the plots. According to the result of variance analysis, different zinc application in wheat cultivars had significant effect on the grain quality parameters. But zinc fertilization had no effect on test weight. The effect of Zn treatment found statistically important on sedimentation and wet gluten content of flour, Zn, P and crude protein contents of bran and flour. In all cultivars, Zn application increased sedimentation, wet gluten content, protein, Zn content and P content in bran. However, the Zn application decreased the amount of P in flour. Also, protein, Zn and P contents were higher in the bran than in the flour. In the research results, it was found that Zn application had a positive effect on quality parameters, but high Zn doses affected both grain yield and quality parameters negatively.

The Effect of Foliar Zinc Application on the Leaf Chlorophyll Concentrations and Grain Yields of the Winter Wheat (Triticum aestivum L.) in the Field Experiments of Two Seasons

“…Their experiments proved that zinc positively influenced both the yield and the quality parameters of winter wheat. In Turkey, the studies of ˙Ilknur [49] showed that the administration of increased doses of zinc had a favorable effect on the content parameters of wheat, and its bakery values improved especially. A similar result was obtained by Peck et al [50].…”

Response of Rice (Oryza sativa L.) to Soil and Foliar Application of Nano-ZnO and Bulk Zn-fertilizer in Red Acidic Soil of West Bengal, India

“…Afzal et al (2017) reported that Zn application both as soil and foliar spray significantly increased wheat grain protein content in comparison to control (9.20%). Crude protein content in both bran and flour of wheat increased significantly with Zn application (Akgun et al, 2017). El-Dahshouri et al (2017) Kumar et al (2017) reported that basal application of Zn as ZnO at the rate of 5 kg/ha increased protein content in rice grain and straw in comparison to control.…”
