Farm Table says:

It is a challenge to develop cotton cultivars that can tolerate plant abiotic stresses while having high potential NUE for the future.

What is the problem?

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.

What did the research involve?

There are no actual research or experiment conducted in this paper. This paper is merely a review of past data.

What were the key findings?

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.

Final Comment

Improving crop productivity is one of the most important challenges in agriculture. Abiotic stresses result in a reduction in plant-water relations, gaseous exchange, photosynthetic pigments, antioxidants, enzyme activities, nutrient uptake, and, ultimately, yield and yield components.
