“…At high N fertilization rates and under long-term [ 66 ] exposure to nitrates (more than 3 days), the inhibitory effect is large and possibly associated with an increase in O 2 diffusion resistance inside the bacteroid [ 69 ]. Although urea is an amidic source of N, after initial hydrolysis of (NH₂)₂CO, the oxidation of N-NH 4 + to N-NO 3 − naturally occurs, which is a fundamental core process in the global biogeochemical N cycle [ 70 ]. There is also a complex hormone signaling between roots and Bradyrhizobium sp.…”

“…Additionally, non-enriched plants were sampled to determine the background 15 N abundance in the fertilized and unfertilized soils, in order to account for possible small variations in the standard values of natural 15 N abundance [94,95]. The sequence of procedures and equations was also assessed by Paulo et al [70]. Thus, the accumulated N in shoots and grains was obtained by the product of total N concentration in tissue and produced biomass.…”

This study was designed to investigate the effects of Azospirillum brasilense and Bradyrhizobium sp. co-inoculation coupled with N application on soil N levels and N in plants (total N, nitrate N-NO3− and ammonium N-NH4+), photosynthetic pigments, cowpea plant biomass and grain yield. An isotopic technique was employed to evaluate 15N fertilizer recovery and derivation. Field trials involved two inoculations—(i) single Bradyrhizobium sp. and (ii) Bradyrhizobium sp. + A. brasilense co-inoculation—and four N fertilizer rates (0, 20, 40 and 80 kg ha−1). The co-inoculation of Bradyrhizobium sp. + A. brasilense increased cowpea N uptake (an increase from 10 to 14%) and grain yield (an average increase of 8%) compared to the standard inoculation with Bradyrhizobium sp. specifically derived from soil and other sources without affecting 15N fertilizer recovery. There is no need for the supplementation of N via mineral fertilizers when A. brasilense co-inoculation is performed in a cowpea crop. However, even in the case of an NPK basal fertilization, applied N rates should remain below 20 kg N ha−1 when co-inoculation with Bradyrhizobium sp. and A. brasilense is performed.

“…Similarly, N application in the forms of controlled and slow-release fertilizers such as polymer-based, urease, and nitrification inhibitors also reported enhancing N uptake and its accumulation in plants ( Antille and Moody, 2021 ). Nitrogen supply from enhanced-efficiency nitrogenous fertilizers, such as 3,4-Dimethylpyrazole phosphate, has been well recognized to reduce N losses and enhance its efficiency in crops including cotton ( Suter et al, 2020 ; de Paulo et al, 2021 ; Qiao et al, 2021 ). Recently, nano-fertilizers with unique nano properties (1–100 nm size of the particle) have gained popularity due to their higher nutrient use efficiency ( Suppan, 2017 ).…”

Nitrogen is a vital nutrient for agricultural, and a defieciency of it causes stagnate cotton growth and yield penalty. Farmers rely heavily on N over-application to boost cotton output, which can result in decreased lint yield, quality, and N use efficiency (NUE). Therefore, improving NUE in cotton is most crucial for reducing environmental nitrate pollution and increasing farm profitability. Well-defined management practices, such as the type of sources, N-rate, application time, application method, crop growth stages, and genotypes, have a notable impact on NUE. Different N formulations, such as slow and controlled released fertilizers, have been shown to improve N uptake and, NUE. Increasing N rates are said to boost cotton yield, although high rates may potentially impair the yield depending on the soil and environmental conditions. This study comprehensively reviews various factors including agronomic and environmental constraints that influence N uptake, transport, accumulation, and ultimately NUE in cotton. Furthermore, we explore several agronomic and molecular approaches to enhance efficiency for better N uptake and utilization in cotton. Finally, this objective of this review to highlight a comprehensive view on enhancement of NUE in cotton and could be useful for understanding the physiological, biochemical and molecular mechanism of N in cotton.
