Effect Of Spraying With Nano Selenium And Salicylic Acid In Reducing Salt Stress And Growth And Yield Of Corn (Zea Mays L.)

Abstract

The experiment was conducted during the spring season 2019-2020 in the Al-Babara area of Al-Imam sub-district in Al-Mahaweel District, Babylon province in clay loam soil by designing Randomized Complete Block Design RCBD according to the split-plot system to study the effect of irrigation water salinity and spraying with nano-selenium and salicylic acid on some soil trait, growth and yield of corn. Three levels of salinity of irrigation water were used (8, 4, 1.8) DS. m-1 and spraying with three concentrations of nano-selenium (0, 30 and 60) mg.L-1 and two concentrations of salicylic acid (0 and 100) mg.L-1 and three replicate, bringing the number of experimental units to 54 experimental units. Increasing the salinity of the irrigation water led to a decrease in most of the studied plant traits, as well as the concentrations of selenium, nitrogen, phosphorous and potassium in the plant.
