Drought stress, being the inevitable factor that exists in various environments without recognizing borders and no clear warning thereby hampering plant biomass production, quality, energy. It is key important environmental stress occurs due to temperature dynamics, light intensity, low rainfall. Despite this, its cumulative, not obvious impact multidimensional nature severely affects morphological, physiological, biochemical molecular attributes with adverse on photosynthetic capacity. Coping water scarcity, plants evolve complex resistance adaptation mechanisms including physiological responses, which differ species level. The sophisticated regularity network improves tolerance are briefly discussed. Growth pattern structural reduction transpiration loss through altering stomatal conductance distribution, leaf rolling, root shoot ratio length increment, accumulation of compatible solutes, enhancement efficiency, osmotic hormonal regulation, delayed senescence strategies adopted by under deficit.

Biochar is gaining significant attention due to its potential for carbon (C) sequestration, improvement of soil health, fertility enhancement, and crop productivity quality. In this review, we discuss the most common available techniques biochar production, main physiochemical properties biochar, effects on including physical, chemical, biological parameters quality fertility, nutrient leaching, salt stress, addition, impacts addition salt-affected heavy metal contaminated soils were also reviewed. An ample body literature supports idea that amended with has a high increase concomitant in structure, use efficiency (NUE), aeration, porosity, water-holding capacity (WHC), among other amendments. However, increases biochar-amended are frequently reported coarse-textured sandy compared fine-textured fertile soils. effect microbial community composition abundance. The negative polluted have plant growth yield components such as aggregation stability can be ameliorated by application biochar.
