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. Approaches for drought alleviations breeding strategies, genomics perspectives special emphasis omics technology alteration i.e., metabolomics, proteomics, genomics, transcriptomics, glyomics phenomics improve plants. For induction, seed priming, growth hormones, osmoprotectants, silicon (Si), selenium (Se) potassium application worth using conditions In addition, microbes, hydrogel, nanoparticles applications metabolic engineering techniques regulate antioxidant enzymes activity plants, enhancing maintenance cell homeostasis ameliorates effects great potential agriculture.

Nanotechnology is playing a significant role in addressing vast range of environmental challenges by providing innovative and effective solutions. Heavy metal (HM) contamination has gained considerable attention recent years due their rapidly increasing concentrations agricultural soil. Due to unique physiochemical properties, nanoparticles (NPs) can be effectively applied for stress alleviation. In this review, we explore the current status literature regarding nano-enabled agriculture retrieved from Web Science databases published January 2010 November 2020, with most our sources spanning past five years. We briefly discuss uptake transport mechanisms, application methods (soil, hydroponic foliar), exposure concentrations, impact on plant growth development. The contained sufficient information about NPs behavior plants presence pollutants, highlighting alleviation mechanism overcome HM stress. Furthermore, present broad overview advances possible interaction between system. Additionally, review article will supportive understanding phytoremediation micro-remediation contaminated soils also highlights future research needs combined soil sustainable agriculture.

A pot study was conducted to explore the effectiveness of zinc oxide nanoparticles (ZnO NPs) foliar exposure on growth and development wheat, (Zn) cadmium (Cd) uptake in Cd-contaminated soil under various moisture conditions. Four different levels (0, 25, 50, 100 mg/L) these NPs were foliar-applied at time periods during wheat. Two regimes (70% 35% water holding capacity) maintained from 6 weeks germination till plant harvesting. The results revealed that wheat increased with ZnO treatments. best found mg/L normal level. lowest Cd highest Zn concentrations also examined when applied without deficit stress. In grain, decreased by 26%, 81% 87% while conditions, 35%, 66% compared control treatment used 50 mg/L. boosted up leaf chlorophyll contents oxidative stress enhanced superoxide dismutase peroxidase activities than control. It can be suggested use might an efficient way for increasing yield maximum minimum drought decreasing chances movement other environmental compartment which may possible NPs.
