Abstract

The food demand over the world is increasing due to the rapid increase in the population. Direct and indirect effects of climate change have severely affected the growth and development of crops. Of these, abiotic stress factors are reported to cause a reduction in crop productivity ranging from 51 percent to 82 percent. Abiotic stresses like drought, waterlogging stress, salt stress, soil acidity, metal toxicities and temperature variations have overwhelming impact on the growth and productivity of crops. Abiotic stress causes increase in reactive oxygen species (ROS) levels and affects various physiological processes, causing reduction in plant growth and yield. Nutrient management proves to be an effective strategy for alleviating various abiotic stress factors affecting agricultural crops. Nutrients such as nitrogen, potassium, calcium and magnesium increase the production of antioxidant enzymes such as superoxide dismutase, peroxidase, catalase and reduces ROS production. Micronutrients such as iron, boron and zinc as well as biofertilizers improve plant adaptation to various stresses through activation of antioxidant enzymes. Current review focuses on the impact of mineral nutrients, organic amendments and biofertilizers in alleviating abiotic stress in agricultural crops.
