Effects of abiotic stresses on crop yield: A review

Author(s):

Abstract:
Approximately 9% of the earth's surface is covered by crops, with 91 percent of that being subjected to various stresses. Abiotic stresses account for around half of all yield losses, with high temperatures (20%), low temperatures (7%), salinity (10%), drought (9%), and other abiotic stresses accounting for the rest (4%). Abiotic stresses such as drought, heat, and salinity have a significant impact on agricultural productivity. Since there is no way to expand agricultural land, increased production from these stressed lands is essential to satisfy the ever-increasing demand. This review summarized crop responses to abiotic stresses in terms of morphological, physiological, and biochemical responses on some of the crops. To combat those stresses, better crop management practice such as conservation tillage, zero tillage and increased water use performance, as well as the application of micronutrients and phytohormones are needed.
