Effects of zinc application rate and zinc distribution relative to root distribution on grain yield and grain Zn concentration in wheat

Effects of ZnSO4 and Zn‐EDTA applied by broadcasting or by banding on soil Zn fractions and Zn uptake by wheat (Triticum aestivum L.) under greenhouse conditions

“…Similar results were obtained by McBeath and McLaughlin (). Contrary to our results, other researchers found higher use efficiency for banded application than broadcast application ( Zhang et al., ; Imran and Rehim , ; Liu et al, ). In these studies, Zn was applied at specific depths (0–15/0–30 cm) and the experiments were performed with maize, in which half of the root biomass was found in the 0–15 cm soil layer ( Peng et al, ).…”

Zinc–nitrogen interaction effect on wheat biofortification and nutrient use efficiency

“…Liu et al. () reported that high‐yielding wheat crops needed a concentration of 2 mg Zn DTPA‐extractable kg −1 soil at crop maturity through a soil application strategy. Those findings are not consistent with our results, i.e ., higher yields in some treatments ( e.g ., ZnAA or ZnGluc) with a lower concentration of soil DTPA‐Zn (< 2 mg kg −1 ) compared with ZnSul.…”

“…As in Liu et al. (), the highest grain Zn biofortification rates were obtained with > 4 mg Zn DTPA‐extractable kg −1 (see Fig. ).…”

Characterizing bread wheat genotypes of Pakistani origin for grain zinc biofortification potential

“…In the present study, grain Zn concentration in wheat genotypes ranged from 23.7 to 33.9 mg kg −1 ; however, this range improved to 31.4–50.9 mg kg −1 with Zn application (Table ), as soil Zn fertilization increases DTPA‐extractable Zn, which possibly enhanced the Zn uptake by wheat and ultimately increased the grain Zn accumulation. Moreover, soil Zn fertilization has a positive influence on grain Zn concentration . The grain Zn concentration in wheat genotypes followed the order Blue Silver > GA‐02 > Millat‐2011 > Fsd‐83 > Fsd‐2008 > Sehar‐2006 > Potohar > Ufaq‐2002 > Pasban‐90 > SH‐02 > Kohinoor‐83 > Shafaq‐2006 > Chenab‐2000 > Pak‐81 > Punjab‐96 > AARI‐2011 > Inqlaab‐91 > Punjab‐2011 > Fsd‐85 > Fareed‐2006 > Sandal‐73 > AAS‐2011 > MH‐97 > Iqbal‐2000 > Mairaj‐2008 > Lasani‐2008 > Chakwal‐50 > Bakhar‐2002.…”

“…Moreover, soil Zn fertilization has a positive influence on grain Zn concentration. 44 The grain Zn concentration in wheat genotypes followed the order Calcium is also vital for human nutrition even if plants are receiving abundant Ca. There was wide variation in Ca concentration in the grain and grain fractions of wheat genotypes.…”
