“…In this method, one portion is applied before tillage as a basal N fertilizer, and the other is used as topdressing during later growth (Wang et al, ). Split application minimizes inorganic N leaching and enhances N use efficiency (Moe et al, ). Nevertheless, the topdressing application requires extra labor and is inconvenient during the later growth period.…”

Crop production must be increased in order to ensure a sustainable food supply for the growing world population. Controlled‐release urea (CRU) improves nutrient use efficiency and saves labor, but its use in crop production is limited due to its high cost. Bulk blending urea (BBU) consists of both CRU and conventional urea and could be an excellent substitute or replacement for CRU. Nevertheless, its economic benefits and soil environment impact are unknown. A 3‐year field experiment was conducted to investigate the effects of two different nitrogen management practices in terms of economic benefits, soil mineral nitrogen availability, aggregate stability, and soil microbial communities. Split applications of conventional urea (UREA) and a single application of BBU were tested on winter wheat (Triticum aestivum L.) and summer maize (Zea mays L.) in the North China Plain between 2010 and 2013. Crop yields were measured after each harvest, and soil environmental parameters were determined after the 3‐year crop sequence. Relative to UREA, BBU significantly increased net revenue, soil inorganic nitrogen concentration, and the functional diversity of the soil microbial community without adverse effects on the soil bacterial community composition. On the other hand, BBU reduced the amount of soil macro‐aggregates and the mean weight diameter value of soil water‐stable aggregates. Although BBU showed great potential for improving wheat–maize cropping systems in the North China Plain, future studies should focus on optimizing the nitrogen dosage and the CRU ratio in BBU to decrease nitrogen leaching, avoid soil aggregate deterioration, and maintain crop yield.

The split application of N at critical growth stages (tillering or PI) coincides with crop demand and resulted in better performance of crop (Moe et al 2014).…”

The major challenge in sustainable rice production is to achieve the goals of increasing crop productivity, profitability, and resource use efficiency. Production systems (PS) and nitrogen (N) management patterns are two key agronomic practices influencing crop performance, profitability, water use efficiency (WUE), and N use efficiency (NUE). So, this study was conducted to check the influence of split application of N on rice productivity, NUE and profitability under dry direct-seeded rice (DDSR) and transplanted rice (TPR) systems. A field study was conducted in the summer season of 2017 and 2018 to investigate the influence of two PS (dry direct-seeded rice = DDSR and transplanted rice = TPR) and six N management treatments (N 1 = control, N 2 = 50 kg N ha −1 as basal, N 3 = 100 kg N ha −1 as basal, N 4 = 150 kg N ha −1 as basal, N 5 = 100 kg N ha −1 in three splits and N 6 = 150 kg N ha −1 in three splits) on crop productivity, profitability, and resource use efficiency. Yield-related traits, spikelet sterility, WUE, and profitability aspects were significantly influenced by PS. All aspects of crop performance, kernel quality, N uptake, and NUE (except NUE on biomass basis = NUEB) were affected by N management pattern, while no significant interaction between PS and N management was observed for any aspect. On average, DDSR improved the productive tiller density (26%), biological yield (16%), WUE (14%), and NUEB (27%) as compared with TPR. Similarly, DDSR reduced the cost of production (31-43%), while maintaining statistically similar paddy yields and reducing total water inputs (5-17%) in comparison with TPR. Among N management pattern, 100 kg N ha −1 in three splits increased paddy yields (44%), and WUE (42%) as compared with the basal application of 100 kg N ha −1. Similarly, application of N at 100 kg ha −1 in three splits improved the total N uptake (42%), agronomic NUE (146%), apparent recovery efficiency (226%) while reducing the spikelet sterility (28%) as compared with the basal application of 100 kg N ha −1. The DDSR has the potential to maintain or increase yield, WUE, NUE, and economic returns. While, split application of N at 100 kg ha −1 either in DDSR or TPR not only increased the SPADchlorophyll value, WUE, NUE, and economic returns but also reduced the spikelet sterility.

“…From the full heading to maturity stage, the decrease rate of root dry weight and root activity was delayed under W1 with an increasing ratio of topdressing fertilizer, but to what extent of the increase needs to be further studied. Root growth and elongation, leaf photosynthetic capacity, and adaptability to AWD were enhanced under AWD couple N2, while the potential decline in N3 treatment may be caused by very few basal fertilizer amounts, and the whole rice plant can still absorb basal fertilizer from the soil after full heading ( Moe et al, 2014 ).…”

“…The N 15 tracer method revealed that nitrogen absorbed during early growth is used mainly in the vegetative period ( Ata-Ul-Karim et al, 2017 ; Wang et al, 2017b ). Excessive fertilizer application at the early growth stages reduce root length, surface area, volume, and CGR at the later growth stages ( Moe et al, 2014 ). Excess or deficient nitrogen temporarily promotes early root growth.…”

Water shortages and nitrogen (N) fertilizer overuse limit japonica rice production in Northeastern China. The interactions between water-saving irrigation and nitrogen management on rice root and shoot growth is still our research focus. Here, japonica rice (DN425) was subjected to the irrigation methods W1 (flooding irrigation), W2 [mild alternate wetting and drying irrigation (AWD); −10 kPa], W3 (severe AWD; −30 kPa), and different N fertilizer ratios were applied in different growth stages, namely, N1 (6:3:1:0), N2 (5:3:1:1), and N3 (4:3:2:1). From jointing to full heading stages, the highest photosynthate production capacity and root activity were obtained under W1N2. AWD markedly affected the root system and resulted in root senescence at later growth stages. Grain yield and N utilization efficiency were closely and positively correlated with the relative water content, crop growth rate (CGR), leaf area duration (LAD), the increase rate of root length density, root surface area density, and root volume density (RVD) from the jointing to full heading stages. This positive correlation was also observed in the increased rate of root bleeding sap (RBS) under W1N2 and CGR under W2N3. From full heading to maturity stages, N2 could promote root growth, LAD, and CGR under AWD to a greater extent than those under the other treatments. Water use efficiency (WUE) and N uptake efficiency (NUpE) were both negatively associated with the decreased rate of RVD, root dry weight (RDW), and RBS. They were closely and positively correlated with the increased rate of RDW and CGR. Our results suggested that W2N2 treatment delayed root senescence, maintained leaf photosynthesis, optimized the crop growth rate from full heading to maturity stages, and improved grain yield. The optimal grain yield, WUE, and NUpE were achieved at the irrigation water amount and topdressing fertilizer ratio of 41.40–50.34 × 102 and 31.20–34.83 kg ha–1, respectively.
