Plant Nutrients for Crop Growth, Development and Stress Tolerance

• Abiotic stress is a problem of grave concern for the growth and productivity of plants in modern times. Abiotic stresses, such as drought, salinity, extreme temperatures and extreme radiation, are responsible for huge crop losses globally. Plants face a combination of different abiotic stresses under field conditions that are lethal to plant growth and production. Exposure of plants to biotic and abiotic stress induces a disruption in plant metabolism implying physiological costs and thus leads to a reduction in fitness and, ultimately, in productivity. Abiotic stress is one of the most important features of and has a huge impact on growth, and consequently, it is responsible for severe losses in the field. The resulting growth reductions can reach more than 50% in most plant species. One of the physiological processes greatly affected by these stresses in plants is photosynthesis. The decline in photosynthetic capacity of plants due to these stresses is directly associated with reduction in yield. Application of nutrients to overcome nutrient stress positively affects plant growth, yield and quality. Transition/heavy metals such as zinc, manganese and copper are essential minerals for healthy plant growth. Micronutrients are essential for balanced nutrition in plants under abiotic stress conditions. The present chapter describes the role of macro- and micronutrients under stress conditions. In this chapter, we have discussed a variety of macro- and micronutrients which are beneficial for plant physiological development under stress conditions.
