Effects Of Different Foliar Zinc And Nitrogen Doses And Treatment Periods On Kernel Nutrient Contents Of Bread Wheat
Öz
This research was carried out to determine the effects of different doses and application times of zinc and nitrogen on bread wheat. The experiments were carried out in field conditions at two different locations, with 4 replications in divided splits parcel design in random blocks. Foliar nitrogen and zinc were applied to wheat at pre-anthesis (tillering and bolting) and post-anthesis (early milk stage and early dough stage) periods. 0 % (- urea) and 0.5 % (+ urea) doses were used for foliar nitrogen applications. 0 %, 0.1 %, 0.3 % and 0.5 % ZnSO4 solution were used for Zn applications. The effects of foliar nitrogen and zinc treatments on grain nitrogen (%), zinc and iron concentrations (mg kg-1), yield (kg da-1) and 1000-grain weight of Adana-99 bread wheat cultivar were investigated.
In general, the effect of Zn application on the grain N concentration was statistically insignificant in Hacıali location, whereas it was found significant in Doğankent location. In both Hacıali and Doğankent locations, the effect of Zn application on grain Zn concentration was statistically significant. The highest Zn concentration in both urea (+ urea and - urea) applications was obtained from 0.5 % ZnSO4 application. In both location, Zn application to soil has a positive effect on Fe concentrations. Post-anthesis applications were more effective on grain Zn concentrations.
