Abstract
Selenium is considered to be beneficial element required by humans. According to World
health organization about 55 µg/day of Se is required by adults, but our daily diet is lacking in
it. The current study examined the effects of soil applied selenium (Sodium selenate) viz. 0,
-1
10, 20, 30 and 40 g ha ,at heading stage, on yield, Selenium and nutritional status of wheat
crop. The experiment comprised of ten wheat genotypes viz. Shafaq-2006, Lasani-2008, FSD-
08, AARI-2011, Punjab-2011, Millet-2011, Fakhar-e-Bhakkar-2017, Ujala-2016, Anaj-2017
and Gandum-1, followed by three replications. The soil applied Se significantly increased grain
Se, Fe, Zn, Ca, K contents in all wheat genotypes but a significant increase was observed in
-1
case of Ujala and Anaj treated with 40 g Se ha . The maximum wheat grains Se contents (106.5
-1
µg/ kg) were observed in Ujala grown under treatment of 40 g Se ha followed by Anaj Se
contents (95 µg/ kg) as compared with other genotypes and the minimum Se contents were
observed in Shafaq and Lasani (5.5 and 3.5 µg Se/kg respectively) where no Se was applied
to soil. The significant escalation was observed in grains Fe contents 58 mg/kg and 56.6 mg/kg
in Ujala and Anaj respectively. Likewise maximum grains Zn contents were in Ujala and Anaj
(52.88 mg/kg and 50.39 mg/kg respectively). In terms of wheat grains Ca contents Ujala and
Anaj again shows highest amount in contrast with all other genotypes (561.95 mg/kg and 567.7
mg/kg). Also the grain K contents were shown to be significantly up scaled by soil applied Se
at 40 g ha-1, with 5.19 g/kg and 6.09 g/kg in case of Ujala and Anaj genotypes respectively.

Conclusively, soil amended with Selenium (40 g ha ) is considered to be effective way of
improving wheat grains Se and other minerals status in wheat that could be a sustainable
approach towards improving Se status in human diet which can add up towards mineral
malnutrition mitigation and ultimately improving food security.
