“…However, N is easily leached to the lowest soil layers in the form of nitrate, which would reduce NUE and increase the environmental impacts of N (Min et al 2012). Therefore, precise N fertilization strategies should consider using different N fertilization forms and splitting the fertilizer dose into different fertilization or topdressing application times based on plant requirements, in order to increase crop yield but decrease N inputs (Crusciol et al 2019;Diacono et al 2012;Peng et al 2010). Positive effects resulting from split topdressing strategies have been previously documented in multiple plants, such as rice, wheat, maize, peanut, and potato (Fan et al 2009;Goffart et al 2008;Wang et al 2016b;Zhong et al 2018), while little research has been focused on other herbaceous plants, including stevia.…”

The nitrogen (N) management is crucial to stevia growth and steviol glycoside (SG) production. Although previous studies have concentrated on the impacts caused by N fertilization rates, very few studies are concerning N topdressing strategies. We hypothesized that stevia biomass and SG productivity can be effectively increased by altering the ratio of base fertilization:first topdressing at the seedling stage:second topdressing at the branching stage. The current plot experiment was undertaken to evaluate such effects. Compared with one-time basal fertilization, optimized N topdressing ratios (especially the 5:3:2 and 4:3:3 ratios) significantly enhanced the leaf biomass formation and aboveground N accumulation. Different results were observed for the leaf SG concentrations, and increasing the topdressing proportions critically reduced the total leaf SG concentrations (3.3-24.7%) at the harvest stage. The highest values for total SG accumulation were exhibited under the 6:4:0 and 5:3:2 topdressing strategies, which depend on the changes in biomass and SG concentration. Moreover, a significant negative correlation between leaf SGs and the N concentration was observed at all growth stages, but a positive correlation was observed with the leaf C/N ratio and soluble sugar concentrations. Our results suggest the potential for increasing SG productivity by optimizing N fertilization regimes, especially with an appropriate reduction in the topdressing ratio after the vegetative growth stage. Our findings further expanded the effect of topdressing strategies on SG production based on the N fertilization levels.

“…The injudicious use of N fertilizers causes lodging in crops and reduced economic yield. Crusciol et al ( 2019 ) observed that proper application methods reduced N volatilization and the number of seeds per spike. The optimum N fertilizers rate proved to increase thousand-grain weight, protein contents, NUE, and wheat yield (Zhang et al 2015 ).…”

Higher demands of food led to higher nitrogen application to promote cropping intensification and produce more which may have negative effects on the environment and lead to pollution. While sustainable wheat production is under threat due to low soil fertility and organic matter due to nutrient degradation at high temperatures in the region. The current research explores the effects of different types of coated urea fertilizers and their rates on wheat crop under arid climatic conditions of Pakistan. Enhancing nitrogen use efficiency by using eco-friendly coated urea products could benefit growers and reduce environmental negative effects. A trial treatment included N rates (130, 117, 104, and 94 kg ha-1) and coated urea sources (neem coated, sulfur coated, bioactive sulfur coated) applied with equal quantity following split application method at sowing, 20 and 60 days after sowing (DAS). The research was arranged in a split-plot design with randomized complete block design had three replicates. Data revealed that bioactive sulfur coated urea with the application of 130 kg N ha-1 increased chlorophyll contents 55.0 (unit value), net leaf photosynthetic rate (12.51 μmol CO2 m-2 s-1), and leaf area index (5.67) significantly. Furthermore, research elucidates that bioactive sulfur urea with the same N increased partial factor productivity (43.85 Kg grain Kg-1 N supplied), nitrogen harvest index (NHI) 64.70%, and partial nutrient balance (1.41 Kg grain N content Kg-1 N supplied). The neem-coated and sulfur-coated fertilizers also showed better results than monotypic urea. The wheat growth and phenology significantly improved by using coated fertilizers. The crop reached maturity earlier with the application of bioactive sulfur-coated urea than others. Maximum total dry matter 14402 (kg ha-1) recorded with 130 kg N ha-1application. Higher 1000-grain weight (33.66 g), more number of grains per spike (53.67), grain yield (4457 kg ha-1), and harvest index (34.29%) were obtained with optimum N application 130 kg ha-1 (recommended). There is a significant correlation observed for growth, yield, and physiological parameters with N in the soil while nitrogen-related indices are also positively correlated. The major problem of groundwater contamination with nitrate leaching is also reduced by using coated fertilizers. Minimum nitrate concentration (7.37 and 8.77 kg ha-1) was observed with the application of bioactive sulfur-coated and sulfur-coated urea with lower N (94 kg ha-1), respectively. The bioactive sulfur-coated urea with the application of 130 kg N ha-1 showed maximum phosphorus 5.45 mg kg-1 and potassium 100.67 mg kg-1 in the soil. Maximum nitrogen uptake (88.20 kg ha-1) is showed by bioactive sulfur coated urea with 130 kg N ha-1 application. The total available NPK concentrations in soil showed a significant correlation with physiological attributes; grain yield; harvest index; and nitrogen use efficiency components, i.e., partial factor productivity, partial nutrient balance, and nitrogen harvest index. This research reveals that coating urea with secondary nutrients, neem oil, and microbes are highly effective techniques for enhancing fertilizer use efficiency and wheat production in calcareous soils and reduced N losses under arid environments.

“…The main N loss pathway in flooded rice soils is through ammonia (NH 3 ) volatilization (Ladha et al, 2005;Dong et al, 2012;Crusciol et al 2019). Broadcast application of PU results in higher amounts of ammonium N (NH 4 + -N) in floodwater, which increases NH 3 volatilization (Huda et al, 2016).…”

A field experiment was conducted to investigate the dynamics of ammonium nitrogen (NH 4 +-N) in the soil during an entire ricegrowing season. The NH 4 +-N dynamics were measured in paddy soils from two N application methods, namely, urea deep placement (UDP) and broadcast prilled urea (PU). The pore water samples from a 10 cm soil depth were collected using a "rhizon sampler." The samples were collected at 0, 7, 10, 14, 20, and 22 cm from the urea briquette (UB) placement point at 7, 14, 21, 35, 64, and 83 days after transplanting (DAT) of rice. The NH 4 +-N in the floodwater sample was measured for a week after each split application of PU. UDP retained NH 4 +-N at the placement site (7-10 cm depth) until 64 DAT. A small amount of NH 4 +-N moved horizontally up to 14 cm from the placement site. It's movement to the soil surface and floodwater was very low to negligible. In contrast, PU produced more NH 4 +-N in both the floodwater and in the soil surface. Therefore, broadcast urea had significantly (p < 0.05) higher ammonia volatilization (~15% of applied N) compared to UDP (<1%). UDP significantly (p < 0.05) increased grain yields, N uptake, and N recovery compared to broadcast urea. These results confirm that a single application of UDP could meet plants' N demand throughout the rice-growing period, particularly for short-and medium-duration rice varieties.
