Understanding the role of Humic acids on cereals under saline condition: Review

Abstract

Salinity is one of the most significant abiotic stresses affecting crop production globally. It induces several inhibitory effects on growth and development of several plants. Saline soil reduces the development and productivity of many cereal crops such as rice, wheat, maize and sorghum. There are various chemicals in different parts of the world to improving plant growth against salinity stress. Improving the physiological status expressed in adjusting the osmolytes and nutrients balance of plant cell is a crucial matter for ameliorating the hazards of salinity. Humic acid helps cereals grow under saline conditions by improving soil properties, enhancing nutrient uptake, modulating plant physiological processes, and promoting overall stress tolerance. In this review, we describe the mechanism and influence of humic acid on cereal crops.
