Mineral Stresses and Crop Productivity

Abstract

The science of plant nutrition has made a great progress during the 20th century. It became an established scientific discipline, defining the role of chemical elements supporting plant growth, and has contributed to improvement in plant production and environmental quality. In the present era, environment-harmonic agriculture is required where research on plant nutrition have a very important role to achieve this type of agriculture with no reduction of yield. Optimization of the mineral nutrition is the key way to optimize the production of recently released high yielding crop varieties with very high nutrient requirement. On contrary, the farmer use very less nutrient fertilizer and many a times only one or two nutrients resulting in poor yield due to inadequate and imbalance use of nutrients.
