Salinity stress is an important abiotic stress that adversely affects food production. Selenite is a vital micronutrients required by plants for their physiological growth. The present study is aimed at the effect and dosage of selenite on the germination, emergence growth, reproductive characters, yield and nutritional composition of wheat under salinity stress. Seeds were soaked in different concentrations 0mg/l, 50mg/l, 100mg/l and 150mg/l of Se for eight hours at 26 o C. They were rinsed and dried back to their initial moisture contents. Primed seed were sown. Plants were irrigated eight times with saline water at concentrations of 0 mM, 100 mM and 200mM. When there was no stress, selenite delayed germination of wheat seeds at the beginning, hastening flowering at higher concentrations (100-150mg/l) and drastically improved 31% and 25% growth of radicle and plumule at low concentration (50mg/l) than other treatments. Whereas, during salinity stress, selenite stimulated 25% shoot/root ratio and improved nutritional contents (15% protein and 10 % vitamin C) of wheat was obtained at low concentration (50mg/l). However, selenite at high concentration (100mg/l and 150mg/l) triggered floral budding thus produced greater grain and biomass yield during salinity stress. Therefore, selenite improved the reproduction, yield and nutritional value of wheat under salinity stress. However, wheat reproduction and its development in selenite seed-primed is concentration dependent.
