Abstract
The issue which affected the quality and availability of wheat is not only abiotic and biotic stresses but also climate change.Approximately, a third of agricultural production is produced through out the use of pesticides. Pesticides have harmful impacts on the crops, beneficial microorganisms and the health of human beings. Thus, alternative or chemical-free methods of plant protection prevent from the risks of causing by chemicals. In this study, in order to gain constant dry weight of root an shoot, shoot and root of wheat at three leaves stage were pulled out from the soil then they are separated. In order to a get constant dry weight shoot and root of wheat in an thermostat set to 100 C for 30 minutes. Immediately after cooling, the plants were weighed on a scale. Salicylic acid rates were 0, 0.25, and 0.5 mM, and the oxalic acid rates were 0, 0.1, and 0.2 mM, which were applied via foliar vs. seed treatments. In this experiment the highest germination percentage observed in 0.50mM SA+0.20mM OA and 0.20Mm OA with 99% and 98% respectively compared to 87.7% germination in the control. When treated with salicylic acid and oxalic acid as chemical inducers by seed treatment or foliar spray, affected growth and yield of wheat (Tables 2-5). These studies can be important for research works which is to the proposed to protect wheat crops from abiotic and biotic stresses
