Description To study the effect of soaking time and Zinc and Iron concentration of wheat seed, the lab
and pot experiments were carried out at CCS HAU Hisar. The results of the study revealed that
increased in soaking time the Zinc and Iron content of wheat seed increased significantly over control.
Zinc and Iron content of wheat seed increased with increase in the priming duration of 2, 4 and 6 hours
while it decreased with further increase in priming time of 8, 12 hours. Similarly the increment in Iron
and Zinc concentration from 1% to 4%, the Zinc and Iron content of wheat seed also increased for both
sulphate and chloride salts over control. Under pot experiment study effect of zinc and iron seed
priming on yield, chemical composition of wheat was conducted. It was found that the application of
ZnSO4 increased number of tiller per pot significantly over control. In case of Iron, the number of tiller
per pot increased significantly over control when seed priming was done with FeCl2 4% solution and
FeSO4 4% solution. The highest spike length, number grains per spike of wheat was obtained
with the basal application of ZnSO4 and seed priming with FeSO4 @ 4.0 % solution.
Similarly, maximum 1000 grains weight was recorded under seed priming with ZnSO4 2%
and FeCl2 4%. The biological, grain and straw yield increased significantly over control with
the Zinc and Iron seed priming. Soil application of ZnSO4 significantly increased the biological,
straw and grain yield which is highest as compare to other treatment. Similarly, when seed priming was
done with FeSO4 @ 4.0 % solution gave the maximum biological yield and straw yield. But
the highest grain yield was recorded when seed priming was done with FeCl2 4%. The maximum zinc
content in straw and in grain were achieved where Zn application of 25 kg ZnSO4 ha -1 as
basal is made. In case of Iron, when seed priming was done with FeSO4 @ 4.0 % solution also
gave the highest straw and grain Iron content. The maximum zinc and iron content in straw
and grain was found at 12 hours priming. The maximum uptake of Zinc in straw and grain
was obtained under soil application of ZnSO4. In case of Iron the highest uptake in straw and grain
were obtained with 0.5% FeSO4 solution as foliar application. Under quality parameter
study, Zinc and Iron seed priming was not able to increase quality significant over control.
Under post harvest analysis of soil sample, the highest soil Zinc content was found in the
treatment where Zinc as applied basal as soil application. While the maximum amount of
soil Iron content was found in the treatment where iron was applied as foliar application
