“…SRU prolongs fertilizer efficiency by reducing the nutrient release rate, provides nutrients to crops for a long period of time, promotes crop growth and development, and increases plant height, stem diameter, leaf area index, and dry matter accumulation, thereby providing a good basis for crop yield [12,17,18]. Lyu et al [19] showed that the combined application of SRU and CU could increase the yield of rice, and 60% of SRU in the mixture was the best and worthy of promotion. In our study, the mixture with 70% SRU resulted in the highest yield of rice, which is consistent with the results of Wang et al [20], who showed that the application of a mixture of SRU and CU with 70% SRU could increase rice yield by 26.6%.…”

The effects of one-time basal application of different mixtures of slow-release urea (SRU) and conventional urea (CU) on yield and nitrogen use efficiency (NUE) of rice and wheat were investigated to determine the appropriate ratios of SRU to CU for one-time basal fertilization in a rice–wheat rotation farmland under full residue incorporation. A field plot experiment was used in this study. Six treatments were established as follows: CK (no nitrogen fertilizer applied), T0 (100% CU, 50% applied as basal fertilizer and 50% applied as jointing fertilizer), T3 (one-time basal application of SRU and CU mixture with 30% SRU), T5 (one-time basal application of SRU and CU mixture with 50% SRU), T7 (one-time basal application of SRU and CU mixture with 70% SRU), and T10 (one-time basal application of 100% SRU). The results showed that the combined application of SRU and CU increased the yields of rice and wheat. Treatment T7 resulted in the highest rice yield, and T3 resulted in the highest wheat yield, which were 25.6% and 29.4% higher, than those of treatment T0, respectively. Compared with treatment T0 (application of CU alone), the combined application of SRU and CU resulted in 27.4–96.5% and 22.8–57.1% higher NUE in rice and wheat, respectively.

“…The Chinese government has developed policies targeting the reduction of NH 3 emission from agroecosystem in 2018 (Adalibieke et al, 2021). Recently, many improved N management strategies have been proposed, such as increasing number of N fertilizer application, adjusting the rate and time of N fertilizer application, and application of enhanced efficiency fertilizers (Linquist et al, 2013;Yao et al, 2018b;Rose et al, 2018;Lyu et al, 2021). However, the development of these practices is restricted by a lack of related knowledge, higher cost, or extra labor input (Zhang et al, 2017;Yin et al, 2021).…”

Ammonia (NH 3 ) volatilization losses result in low nitrogen use efficiency (NUE) and various environmental impacts in agroecosystems. Machine-transplanted rice with side-deep fertilization (MRSF) has been recommended as an effective alternative to traditional transplantation with manual broadcasting of fertilizer. Controlled-release nitrogen fertilizer (CRF) can enhance rice yield and NUE in paddy fields. However, there is scarce information about combined effects of MRSF and CRF on NH 3 volatilization loss and rice grain yield, NUE, net economic benefit (NEB) in a double rice cropping system. In this study, a field experiment was conducted to evaluate the impact of MRSF with CRF on grain yields, NUE and economic returns of early rice and late rice from 2019 to 2021, as well as NH 3 emissions in two rice seasons (2019 and 2021). Six treatments were designed as no N fertilizer (N0), compound fertilizer broadcasting (CFB), compound fertilizer side-deep placement (CFD), CRF broadcasting (CRFB), CRF side-deep placement (CRFD1), and single side-deep placement of CRF (CRFD2). The results showed that the CFD and CRFB treatments decreased NH 3 volatilization while enhancing or maintaining rice yield and NUE compared to the CFB treatment. MRSF with CRF (CRFD1 and CRFD2) significantly reduced NH 3 emissions of early and late rice by 57.6-67.9% and 62.2-80.9% by decreasing the NH 4 + -N concentrations in the surface water compared to the CFB treatment, respectively. Rice grain yields in the MRSF with CRF treatments increased by 3.9-17.3% in early rice and 5.4-21.6% in late rice relative to the CFB treatment. In addition, MRSF with CRF treatments improved NUE for early and late rice from 32.1 to 36.2% and 21.3-28.4% in the CFB treatment to 48.4-61.2% and 39.7-62.3%, respectively. The yield-scale NH 3 volatilization losses were reduced under the MRSF with CRF treatments by
