“…These results are consistent with previous studies by Liu et al. (), who found that the grain yield of winter wheat increased when the N rate decreased from 315 to 240 kg ha −1 in a wheat–maize rotation system in the North China Plain. According to the ANOVA results, treatment and year had significant effects on the grain yield of winter wheat but the treatment × year interaction did not.…”

Better N fertilizer management is essential for improving crop productivity and reducing N losses to the environment. However, few studies have reported N absorption, use, and balance in a wheat (Triticum aestivum L.)-peanut (Arachis hypogaea L.) relay intercropping system. This study aimed to determine the effects of different N application rates and ratios at different maturation stages on the yield and N use of peanut in this system. Nitrogen (300 kg ha −1 ) was applied the day before sowing and at jointing, booting, and anthesis in peanut at the following ratios: 50-50-0-0 (N1), 35-35-0-30% (N2), and 35-0-35-30 (N3) (control: 0 kg ha −1 ). Nitrogen isotopelabeled urea was used under the same conditions in microplot. Peanut pod yield increased by 19.0 and 24.8% under the N2 and N3 treatments, respectively, compared with the N1 treatment. Applying N at three stages and withholding N until booting improved the N derived from fertilizer in peanut, promoted the distribution of 15 N to pods, and increased pod yield. The 15 N experiment revealed that N uptake at different growth stages of peanut was 20.7 to 30.4% higher under N3 than under N2, increasing N harvest index and apparent N recovery efficiency compared with N2. The N3 treatment also significantly increased the N recovery efficiency and the agronomic N use efficiency and reduced the apparent N loss. Therefore, applying N fertilizer as in the N3 treatment could be appropriate for wheat-peanut relay intercropping systems in China.Abbreviations: ARE, apparent recovery efficiency; N up , N uptake; NDFF, N derived from fertilizer; NHI, N harvest index; NDR, N distribution rate; NRE, N recovery efficiency; NUE, N use efficiency.

“…Plant density and N management were known to be closely related to N uptake, translocation, and partitioning in previous maize studies (Chen et al., 2015; Ciampitti & Vyn, 2011, 2013; Meng et al., 2016). Aboveground N uptake has been closely linked with grain yield and aboveground biomass (Liu et al., 2018; Setiyono et al., 2010). Abbasi, Tahir, Sadiq, Iqbal, and Zafar (2012) also reported that aboveground N uptake increases with N rate primarily due to the increased aboveground biomass.…”

Rational plant density and fertilizer management are important practices to improve maize (Zea mays L.) yield and nutrient use efficiency. Previous research indicated that plant density and fertilization had positive interaction on maize yield and N utilization. The research studied on the interactive effects of slow‐released fertilizer (added amino acid polymer biological preparation) and density on maize yield and nitrogen use efficiencies (NUEs). A 2‐yr field experiment with varieties Suyu29 (SY29) or Suyu30 (SY30) was conducted using a split‐split plot design. Three densities (6.0, 7.5, and 9.0 × 104 plants per ha) and three fertilization modes (0F‐no fertilizer, SF‐one‐time application of slow‐released fertilizer, and CF‐twice application of conventional fertilizer) were assigned. Results indicated that grain yields and NUEs of SF under 7.5 × 104 plants per ha were the highest both in SY29 and SY30. Compared with CF under 7.5 × 104 plants per ha, SF could improve pre‐ and post‐silking N uptake and promote N translocation from stalk and leaf into grain, which increased its contribution efficiency to grain N content and obtained higher NUE. The average N partial productivity, N agronomic efficiency, N recovery efficiency, and N absorption efficiency of SF were 5.3, 9.9, 20.1, and 11.4% higher than CF under 7.5 plants × 104 plants per ha. Increasing plant density, the grain yield, total N accumulation, and NUEs initially increased and then decreased both in SF and CF. These results suggest that one‐time application of SF combined with appropriate density could increase maize yield and NUE under our experiment condition.

“…On the other hand, the values of T N for N0, FM, OMI, and OMII were found to be statistically similar (p > 0.05) for S0 and S100, for all the growing seasons ( Table 7). The previous study reported that N loss has increased due to excessive N-based fertilizers [37]. Compared with S0, straw return (S100) was found to be beneficial in N uptake and use efficiencies in maize.…”

Nitrogen fertilizer is an important component of crop production; however, its excessive application could result in N loss that could have serious environmental concerns. Straw incorporation in the soil after crop harvest is one of the most feasible straw management techniques, however, the optimization of nitrogen (N) fertilizer management and maize straw incorporation to modulate the crop yield and to maintain N balance in sweet corn is necessary to get better yields on a sustained basis. The present study was comprised of two straw management treatments i.e., (i) no straw return (S0), and (ii) incorporation of crushed corn ears by into the soil using rotary tiller (S100) and four N fertilizer management treatments i.e., (i) common farmer practice with total N applied at 300 kg ha−1 with 50%, 5%, 30%, and 15% splits at basal, 3-leaf stage (V3), at hilling stage (V8) and at tasseling/flowering stage (RT), respectively (FM); (ii) application of total N at 225 kg ha−1 with 40%, 10% and 50% at basal, 3-leaf stage (V3) and at hilling stage (V8), respectively (OMI); (iii) application of total N at 150 kg ha−1 with 40%, 10% and 50% at basal, 3-leaf stage (V3), and at hilling stage (V8), respectively (OMII); and (iv) the treatment without any fertilizer application (N0). The hybrid sweet corn cultivar ‘Yuetian 28’ was grown during the spring and autumn growing seasons of 2016 and 2017. The results showed that the N management treatments substantially improved the fresh ear yield, ear number and ear weight, partial factor productivity from nitrogen (PFPN), recovery efficiency from nitrogen (REN), and agronomic efficiency from nitrogen (AEN). Compared with FM, the OMI and OMII treatments significantly increased the AEN and PFPN whilst decreased the apparent N loss, however, the fresh ear yield, ear number and ear weight in OMI treatment were found to be statistically similar (p ˃ 0.05) to FM. Moreover, the S100 treatment did not affect the fresh ear yield and yield components significantly. Overall, straw return combined with an optimized N fertilizer application could improve the yield of sweet corn on a sustained basis with minimum and/or negligible N loss.
