Plant Nutrition: An Effective Way to Alleviate Abiotic Stress in Agricultural Crops

International Journal of Molecular Sciences, Journal Year: 2022, Volume and Issue: 23(15), P. 8519 - 8519

Published: July 31, 2022

By the year 2050, world's population is predicted to have grown around 9-10 billion people. The food demand in many countries continues increase with growth. Various abiotic stresses such as temperature, soil salinity and moisture all an impact on plant growth development at levels of growth, including overall plant, tissue cell, even sub-cellular level. These directly harm plants by causing protein denaturation aggregation well increased fluidity membrane lipids. In addition direct effects, indirect damage also includes synthesis inhibition, breakdown, membranous loss chloroplasts mitochondria. Abiotic stress during reproductive stage results flower drop, pollen sterility, tube deformation, ovule abortion, reduced yield. Plant nutrition one most effective ways reducing agricultural crops. this paper, we discussed effectiveness different nutrients for alleviating stress. roles primary (nitrogen, phosphorous potassium), secondary (calcium, magnesium sulphur), micronutrients (zinc, boron, iron copper), beneficial (cobalt, selenium silicon) crop are discussed.
