“…Studies indicate that both soil and foliar applications of Zn reduce grain phytic acid (PA) concentration and enhance Zn bioavailability in cereal crops (Kumar et al 2023;Nayak et al 2023b;Wang et al 2023). Co-application of Zn with N has also been shown to decrease grain PA concentration (Li et al 2015;Sharafi 2023;Xue et al 2014b). While (Zhang et al 2012) reported a non-statistically significant decrease in wheat grain PA concentration with foliar Zn and urea applications, Li et al (2015) and Wang et al (2019) found similar non-significant decreases in grain PA concentration with foliar Zn applications, consistent with the results of this study.…”

Zinc deficiency in humans is of worldwide concern. The aim of this study is to enrich grains with Zn through soil application at different doses and foliar application from various sources. For this purpose, two independent field experiments have been conducted. In Experiment I, Zn (ZnSO4.7H2O) was applied through soil as basal and top dressing. The treatments were Zn0: control, Zn1: 5 kg Zn ha−1 as basal, Zn2: 2.5 kg Zn ha−1 as basal and 2.5 kg Zn ha−1 as top dressing and Zn3: 5 kg Zn ha−1 as top dressing. In Experiment II, Zn was applied as foliar from different sources (ZnSO4.7H2O, Zn-Methionine, Zn-Polyol and Zn-EDTA) at different growth stages with or without urea. In both experiments, Zn concentration in the grain and leaves of wheat and grain yield increased while phytic acid and PA/Zn molar ratio decreased due to soil or foliar Zn application. It was determined that the application of ZnSO4.7H2O in the soil at the top dressing period in Experiment I and the application of ZnSO4.7H2O and Zn-Methionine forms together with urea in Experiment II were effective methods in increasing grain yield and grain Zn concentration. The application of ZnSO4.7H2O from both soil and foliar sources, especially in combination with urea, has proven to be highly effective in the Zn biofortification of wheat grains. It is possible to assert that the use of ZnSO4.7H2O, which is cost-effective compared to other sources, could contribute significantly to enhancing zinc nutrition in humans.

The use of nitrogen (N) fertilizers can have detrimental effects on the environment due to nitrate leaching. This study aims to examine the impact of N fertilizer source and application timing on wheat yield and nitrate leaching in various soil textures. A randomized complete block design (RCBD) was employed to conduct the experiment. The treatments consisted of two N fertilizer sources: ammonium nitrate (AN) and urea (NN), applied at three different times throughout the year, with a control treatment. The three application timings were total application before sowing (T1), total application in spring (T2), and half the amount before sowing and the other half in spring (T3). The experiment was conducted in three different soil textures (sandy loam, silty clay loam, and silty clay), with three replications over three growing seasons: 2018-19 (Y1), 2019-20 (Y2), and 2020-21 (Y3). The results indicated significant effects of different soil textures on grain yield. Specifically, the silty clay loam soil differed significantly from the sandy loam and silty clay soils in terms of grain yield. The interaction effects between the N fertilizer source and application timing were also found to be significant for all soil textures (p<0.01). In sandy loam and silty clay soils, the grain yield increased when using the T3 application timing compared to the silty clay loam soil. Notably, the silty clay loam soil with the T2 application timing exhibited the highest grain yield, with a yield of 6863.6 kg ha-1. Furthermore, the study revealed that N fertilizers and their application timing significantly influenced the protein content in the silty clay and sandy loam soils. The protein percentages were 10.76 and 10.93 for the silty clay and sandy loam soils, respectively, following the T2 treatment. Additionally, ammonium nitrate (AN) demonstrated a noticeable effect on the percentage of grain protein compared to urea (NN). In conclusion, the application timing of N fertilizers had an impact on grain yield and protein content in different soil textures. Moreover, nitrate concentration increased throughout the experiment, with the highest soil nitrate concentration observed in both fertilizer treatments, particularly in the sandy loam soil.
