Abiotic and biotic stresses directly affect agricultural productivity

High salinity and temperature suppress plant growth and reduce crop yield

Under stressed environments, plants produce elevated levels of ethylene (C2H4), which at higher concentrations imparts drastic effects on planthealth, including defoliation and other unbalanced cellular processes

Salinity, one of the most serious factors limiting agricultural productivity, adversely affects germination,plant vigour, and crop yield (Paul and Lade, 2014),which becomes more prevalent especially in the aridand semi-arid regions of the world. 

Similarly, drought stress changes chlorophyll contents and damages the photosynthetic apparatus inplants (Ortiz et al., 2015)

Similarly, the stresses such as salinity, heavy metals, nutrient deficiency/excess, and pathogen attack also cause negative impact on plant growth and development in a number ofways that may include hormonal imbalance and susceptibility to diseases and metal toxicity (Miransari,2011; Nadeem et al., 2014
