“…It is continuous task for scientists to make crops hardy against biotic and more importantly abiotic stresses to increase food productivity. The simulation model predicts that to cope with rising food demand, supply must be increased to 70% till the year 2050 [9][10][11][12].…”

The food demand is increasing hastily, that is inducing continuous pressure on agriculture sector and industries to fulfill rising dietary needs. To meet with increasing demand, the food production must be elevated up to 70% until the year 2050. On the other hand, changing climate is disturbing crop production around the World. Crops grown under field conditions are affected by more than one abiotic stress. It is continuous task and challenge for agronomists to make crops environment hardy to obtain maximum yield. It is considered that different agronomic managements, if done appropriately, could be beneficial for increasing crop production. The optimal provision of plant nutrients can assist the crops to fight in better way with environmental stress like drought; it can help them to continue their normal metabolism even under hostile abiotic circumstances. The regions that have reduced availability of water for crop production, a balanced nutrient management can assist crops to give adequate production. Some of nutrients have potential of not only maintaining plant metabolism but also to enhance the quality of product. This chapter highlights the protagonist of plant nutrients in alleviation of drought stress in field crops.

“…Thus, the shallow ground water and aquifers are contaminated through the soluble nature of the NO3 in soil water [150,151]. Worldwide, NO3-N is considered as the major concern as it deteriorates the ground water and surface water quality since few decades [152][153][154]. Increment in the NO3-N contents in drinking water have bad effect on human and animals health as well [155,156], also the aquatic bodies are contaminated through its higher concentration accumulation [157][158][159][160][161][162][163][164] thereby favoring the aquatic plants to grow and nourish well [161,162] by making a surface layer thereby impeding the solar radiation to reach the aquatic fauna [163][164][165][166] and ultimately causing the death of the aquatic fauna [167] which creates eutrophication [168].…”

Drought stress is the most prominent limiting factor and abiotic stress that manipulates the physiological pathway, biochemical traits and hence negatively affects wheat crop productivity. The global nitrogen (N) recovery indicated that about two-fifths of N inputs are lost in the ecosystems through emission, denitrification, gaseous loss, leaching, surface runoff and volatilization etc. Farmers are using higher rates of N to harvest maximum yield but about 50–60% of applied N to crop field is not utilized by the plants and are lost to environment causing environmental pollution. These deleterious environmental consequences need to be reduced by efficient management of N and/or water. N-availability is often regulated by soil water; hence crop is experiencing N- and water-limitation simultaneously. There is great impetus to optimize their uptake through interconnectedness of water and N for yield determination of wheat because of the water scarcity and N losses. It is further advocate that there is need to investigate the intricate role of economizing N rate and water simultaneously for wheat crop growth, yield and backing quality may be beneficial to be investigate.

“…Short-term drought stress affects the plants, which ultimately leads to the decline in growth and yield (Muscolo et al, 2014). Drought stress induced crop yield loss is generally more prominent then other biotic and abiotic stresses, because severity and duration of drought stress are critical (Gul et al, 2020). Drought causes changes in nutrient acquisition and assimilation, water relations, photosynthesis, assimilates partitioning and enzyme functioning (Ayyaz et al, 2021;Xiong et al, 2020;Bano et al, 2021).…”

Background: In the agricultural context, drought is a period of deficient water conditions, resulting in negative effects on crop growth and yield. A continuous increase in global temperature, leading to warmer climatic conditions, is expected to further increase the severity and frequency of drought. Methods: The experiments were carried out during 2018-2019 under laboratory conditions to study the effects of PEG-6000 on seedling growth in eight genotypes of lentil (Lens culinaris Medik.). Result: Our research work evaluated the effect of PEG-6000 induced drought stress on metabolite and enzymatic activity of eight genotypes of lentil (Lens culinaris Medik.) (PL-4, L-4147, L-4594, L-4596 belonging to microsperma subspecies and K-75, L-4076, DPL-15, DPL-62 belonging to macrosperma subspecies). Drought stress significantly increased metabolite content i.e., protein, proline and carbohydrate and enzyme activity i.e., acid phosphatase, invertase in drought tolerant genotypes (PL-4, L-4594, DPL-15 and DPL-62) and reduced amount of these metabolites and enzymes was observed in drought susceptible genotypes (L-4147, L-4596, K-75, L-4076).
