“…The integrated use of various management tools is crucial due to financial and ecological restrictions. Among all these strategies, exogenous application of nutrients is documented as a shotgun approach to reduce the unwanted effects of abiotic stresses (Upadhyaya et al 2012). Application of fertilizer N increases the cost of production for growers and may cause pollution to the groundwater through leaching and contribute to global warming due to emission of nitrous oxide gas (N 2 O) to the atmosphere.…”

This review outlines nitrogen (N) responses in crop production and potential management decisions to ameliorate abiotic stresses for better crop production. N is a primary constituent of the nucleotides and proteins that are essential for life. Production and application of N fertilizers consume huge amounts of energy, and excess is detrimental to the environment. Therefore, increasing plant N use efficiency (NUE) is important for the development of sustainable agriculture. NUE has a key role in crop yield and can be enhanced by controlling loss of fertilizers by application of humic acid and natural polymers (hydrogels), having high water-holding capacity which can improve plant performance under field conditions. Abiotic stresses such as waterlogging, drought, heat, and salinity are the major limitations for successful crop production. Therefore, integrated management approaches such as addition of aminoethoxyvinylglycine (AVG), the film antitranspirant (di-1-p-menthene and pinolene) nutrients, hydrogels, and phytohormones may provide novel approaches to improve plant tolerance against abiotic stress-induced damage. Moreover, for plant breeders and molecular biologists, it is a challenge to develop cotton cultivars that can tolerate plant abiotic stresses while having high potential NUE for the future.

“…Introduction of oxidative pressure under water deficit with more concentration of phenolic and reduced H 2 O 2 , O 2and lipid peroxidation credited to decrease in biological yield (Ruiz et al 2006). Boron facilitated to recover the oxidative damage caused due to water deficit by motivating activity of various enzymes including superoxide dismutase, peroxidase, polyphenol oxidase, catalase and glutathione reductase, thus guaranteeing more dry matter production (Upadhyaya et al 2012). More grain yield of mungbean under water deficit might be due to the role of boron in photosynthesis, pollen viability and source sink relationship (Wei et al 2005).…”

Boron is considered important to improve the drought resistance, yield and protein contents of pulses. Two years of field experiment was conducted to evaluate the effect of boron application and water stress given at vegetative and flowering stages on growth, yield and protein contents of mungbean during spring 2014 and 2015. The experiment was laid out in randomized complete block design with split-plot arrangement giving more emphasis to boron. The experiment comprised three water stress levels (normal irrigation, water stress at vegetative stage and water stress at reproductive phase) and four boron levels (0, 2, 4 and 6 kg ha-1). Final seed yield was significantly increased by different levels of boron application both under normal and water stressed conditions. The increase in yield was mainly due to greater plant height, number of pods bearing branches, number of pods per plant, number of seeds per pod and 1000-grain weight. Boron application at 4 kg ha-1 caused 17%, 10% and 4% increase in grain yield under normal irrigation, stress at vegetative stage and water stress at reproductive phase, respectively. Protein contents were also increased (9-16%) at same boron treatment. Most parameters showed a marked decrease at higher dose (6 kg ha-1) of boron. In conclusion, the boron application at rate of 4 kg ha-1 in clay-loam soil performed the best to enhance mungbean growth, yield and seed protein both under normal and water stressed conditions.

“…Several oxidative stress-related proteins, including SOD, oxidoreductase, and aldehyde reductase, were increased in the root of Vigna radiata in response to drought stress and recovery [23]. Post-drought recovery in Camellia sinensis was enhanced by the foliar spray of potassium, calcium, manganese, and boron, which led to the increased activities of SOD, catalase, peroxidase, and glutathione reductase [24]. Stem hydraulic conductance rapidly returned to the control level after the post-drought irrigation of Eucalyptus pauciflora, suggesting that this species utilizes an active mechanism of repair [25].…”
