“…The foliar S contents also increased linearly as the N rates increased. A part of the N applied as topdressing was provided with ammonium sulfate, and there is a relationship between N and S where an increase in S coupled with nitrogen fertilization promotes the development of maize (AFSAR et al, 2017), resulting in greater absorption of this nutrient. Despite their quadratic response, the foliar Ca and Mg decreased as the N rates were elevated, which can be explained by the dilution effect since higher N rates also led to a higher yield of dry plant matter.…”

The objective of this study was to evaluate the effect of nitrogen topdressing rates applied to an intercrop of maize (M) with paiaguás grass (G) and pigeonpea (P) on silage production and on the pasture development in the offseason. Treatments consisted of two simultaneous intercropping systems (M + G; and M + G + P) and four N topdressing rates (0, 80, 160, and 240 kg ha?1). The introduction of pigeonpea into the system and the increasing N rates provided gains in yield and silage quality. Pigeonpea responded to nitrogen fertilization by having good regrowth and good dry matter yields in the intercrop. For silage making, the N rates of 240 kg ha?1 N for M+G and 120 kg ha?1 for M+G+P can be recommended. Nitrogen rates promote an increase in the dry matter yield of the grass and of pigeonpea, resulting in improvements in the pasture during the offseason.

“…Nitrogen fertilization has a positive effect on the yield of maize crops in that it improves vegetative growth and grain development (AFSAR et al, 2017). For the Cerrado region, the recommended rates for seeding range from 20 to 30 kg ha -1 as topdressing, which may reach up to 180 kg ha -1 (SOUSA; ALVES et al, 1999).…”

“…This is applied to progeny in a breeding based on marker data only without the need of phenotypic evaluation (Tester and Langridge, 2010). For instance Ms44 is an example of specific gene which was done for NUE (Lv et al, 2016;Afsar et al, 2017).…”

“…Reducing N fertilizer use efficiency or retrieval competence by crops is the most problem associated with the use of chemical fertilizers (Lv et al, 2016). Nitrogen fertilizers also account about 25 % of the total input costs (seeds and pesticides) in maize production (Afsar, et al, 2017). The other studies also confirmed that N has a (Hirel et al, 2007), N fertilizer contribute annual energy supply and significant greenhouse gas emissions (Li et al, 2015), due to its volatile nature, it was estimated that 35% to 65% of applied N lost from soil (Koocheki et al, 2013).…”

Maize is the third most prominent crop grown next to wheat and rice globally while extensively affected by stresses; critically abiotic factors like drought and soil acidity are the robust effect. Nitrogen use efficiency (NUE) is an imperative trait in maize to enhance yield with marginal contribution of nitrogen fertilizer. In this review, it has been tried to extant the current progress and the coming projections enlightening the NUE in maize by various mechanisms, especially through conventional breeding and molecular genetics. Of any kind, N fertilizer is amplified the understanding of the appliances prevailing maize N economy is indispensible for refining NUE and plummeting extreme use of fertilizer, whereas retaining an adequate yield and satisfactory income for agrarians. Consuming crops cultivated under managed environments, with various cultivation practices, independently or supplementary principles at minimum and great N inorganic mineral fertilizer expenditure or other organic fertilizer, it is currently conceivable to grow advance the entire maize agronomic and biological revisions. These can be shared with inheritable factor, protein and metabolic sketching to construct a widespread image showing the diverse paces of N acceptance, absorption and recovering to produce either in vegetative biomass or seed protein storage structures. Therefore providing a serious impression in what manner our empathetic of the agro-eco physiological, biological and molecular mechanisms of N adjustment in maize, at different ecological circumstances, has been enhanced. At the movement enduring sustainability is required at maize growing world to limit the application of synthetic N input and avoiding excessive environmental pollution. The knowledge and prospects of the future development and submission for breeding in maize improved at the deprived mineral fertilizer input.
