“…However, this approach does not increase the grain yield and in fact actually reduce economic benefits 25 . Therefore, it is imperative to optimize fertilizer management during the maize growth period, which can not only reduce N input but also improve grain yield and environmental sustainability 26 , 27 . While increased density generally stimulates crop productivity 28 , 29 , reduced N often has the opposite effect on yield 3 , 22 .…”

The combination effects of nitrogen (N) fertilizer and planting density on maize yield, N use efficiency and the characteristics of canopy radiation capture and radiation use efficiency are not well documented in the Huanghuaihai Plain region in China. A 2-year field experiment was conducted from 2017 to 2018 in a split plot design with two N levels (240 and 204 kg N ha−1) applied to main plots and three plant densities (67,500, 77,625 and 87,750 plants ha−1) allocated to sub plots. Our results show that a 30% greater plant density combined with a 15% lower N rate (basal N) enhanced N partial factor productivity (NPFP) by 24.7% and maize grain yield by 6.6% compared with those of the conventional high N rate combined with a low density planting management practice. The yield increase was mainly attributed to significantly increased kernel numbers and biomass. The increased intercepted photosynthetically active radiation (IPAR) was the primary factor responsible for the high productivity of maize at increased planting density under reduced N conditions. The results indicate that increase planting density with reduced basal N application might benefit maize cropping for achieving high yields and sustainable development of agriculture.

“…Prontivesa), used as green manure during the 2020 season and as forage during the 2021 season. The soil tillage treatments were the same as those detailed by Pareja-Sánchez et al (2019). The CT followed the traditional tillage techniques from the area: one rototiller pass (15 cm depth) was followed by one subsoiler pass (35 cm depth), and a disk plough pass (20 cm depth) prior to planting, with almost 100 % of the crop residues being incorporated into the soil.…”

“…It is the ultimate output of plant N absorption and assimilation efficiency of absorbed N. Agronomic operations, the use of controlled released or enhanced efficiency fertilizers, incorporation or impregnation of urea fertilizer to various organic or inorganic materials can significantly increase NUE and yield of corn (Latifah et al, 2017;Martins et al, 2017;Zhang et al, 2017;Kubota et al, 2018). The conventional tillage in the rain-fed condition also increased corn yield and NUE (Pareja-Sánchez et al, 2019) while urea top dressing decreased corn grain yield by 6.8%-9.8%, NUE by 13.2%-14.3% with annual net loss increased by 15.4%-21.8% compared to coated urea at the similar rates of N application (Zheng et al, 2017). In addition, the N uptake in grain increases with the increase of N application frequency compared to a single or double application, while total N uptake and biomass production also increase significantly (Lü et al, 2012).…”

Nitrogen loss minimization is the main challenge to sustainable crop production and reducing environmental and economic losses. There is a new approach to urea application in liquid form (LU) so that the NH4 + can be evenly distributed throughout the soil profile, soil particles adsorb it and reduce the local substrate concentration inhibiting further transformation. Liquid urea has been hydrolyzed even prior to soil application, whereas the urea in granulated urea (GU) must be hydrolyzed after application before it can be transformed to NH4 + . Increased urea application frequency with lower doses can lower the NH4 + concentration in soil compared to a single application. These mechanisms reduce the N loss potential and increase the N crop uptake potential of applied N by conforming to the proper synchronization between N availability and crop N demand as well as reduce N loss potential as NH3 volatilization, NO3leaching and N2O emission. The inconsistent results and clarifications from various studies highlight the importance and benefits of relating the effect of LU application on N loss minimization, N availability and corn (Zea mays L.) yield. This review summarizes the potential ways of N losses and their management and provides the scientific reference to achieve sustainable corn yield and reduce N losses.
