BACKGROUND Excessive application of nitrogen (N) fertilizer and low nitrogen‐use efficiency (NUE) are prevalent problems in rice production. Controlled‐release urea (CRU) is widely adopted to increase rice yields, but the synchronicity of N release from CRU with uptake of N by plants has rarely been studied. A 2‐year field experiment involving CRU and urea applications at three different N rates (240, 192 and 144 kg N ha−1, equal to 100%, 80% and 60% of the recommended rate, respectively) was performed to compare their effects on N uptake, soil N content and rice yields. RESULTS The successive release curves of CRU in the soil matched the corresponding N uptake curves of rice plants, and significant linear correlations were observed. Grain yield and N uptake under the CRU treatment increased by 5.25–7.88% and 7.13–17.94% than urea treatments, at the same N rate, and no obvious difference was found between CRU60% and Urea100%. CRU80% and CRU60% presented the highest NUE. The contents of ammonium‐nitrogen (NH4+‐N), nitrate‐nitrogen (NO3‐‐N), and total N and the chlorophyll relative value – SPAD (Soil Plant Analysis Development) values – of the leaves under the CRU treatments were significantly higher than those under the urea treatments from heading to harvest. The contents of exchangeable sodium ion (Na+) and calcium ion (Ca2+) and the cation exchange capacity increased in response to CRU. CONCLUSION CRU increased rice yields by providing N strongly in synchrony with the N requirements of the plants, and applying CRU at 192 kg N ha−1 was an effective strategy to conserve N fertilizer, increase soil N contents and enhance NUE. © 2021 Society of Chemical Industry

“…Improvement of the canopy photosynthetic capacity have long been considered to be necessary for increasing the yield (Bednarz et al, 2000; Raines, 2011; Dong et al, 2012; Mao et al, 2014). The canopy characteristics of summer maize depend not only on the hybrid but also on the sowing method (Westgate et al, 1997), plant pattern (Liu et al, 2018), and plant density (Maddonni et al, 2001). In the current study, the light transmission significantly decreased at higher plant densities.…”

Under high‐density planting, mixed cropping planting pattern can potentially optimize maize (Zea mays L.) canopy architecture and ultimately improve grain yield. The objectives of this study were to evaluate the effects of three plant patterns combined with three plant population densities (67,500, 82,500, and 97,500 plants·ha−1) on canopy architecture and grain yield. Zhengdan 958 (ZD958) and Denghai 605 (DH605) were used as experimental materials. Three different planting patterns were: mixture (M), random sowing after mixing seeds of the two hybrids in the same proportion; 1:1, one row of ZD958 and one row of DH605; and two monoculture systems, SZD958 and SDH605, as controls. A 3‐yr study demonstrated that the mixed cropping treatments (M and 1:1) at low density (LD) showed no significant difference on light transmission, leaf area index (LAI), canopy apparent photosynthesis (CAP), and canopy respiration (CR), compared with the two monocultures. However, at a medium and high density (MD and HD), mixed cropping was characterized with higher light transmission to the ear and lower layers of the canopy during grain filling than that of monoculture treatments, while no significant differences between M and 1:1 treatments. Moreover, mixed cropping treatments maintained a higher LAI, CAP, lower CR, and increased the whole and post‐silking dry matter accumulation. Grain yields were higher under mixed cropping at MD and high density (HD), while no significant differences between M and 1:1 treatments. Relative to SZD958 and SDH605, the grain yields in the M treatment were 10% and 8% higher at MD, and 7% and 5% higher at HD, respectively. Mixed cropping optimized the canopy structure, maintained higher LAI and CAP during the grain filling period, reduced respiration, and increased aboveground dry matter at maturity. These improvements also result in higher grain yield. Core Ideas Mixed cropping facilitated the formation of a high‐efficiency canopy structure. Mixed cropping delayed the rate of leaf senescence, maintained higher LAI and CAP during the grain filling period. Mixed cropping increased aboveground dry matter weight at physiological maturity, and ultimately led to higher grain yield, especially medium density.

Adaptive highly efficient mulching technologies for use on dryland agricultural ecosystems are crucial to improving crop productivity and water-use efficiency (WUE) under climate change. Little information is available on the effect of using different types of mulch on soil water thermal conditions, or on root/shoot trait, leaf area index (LAI), leaf area duration (LAD), yield, and WUE of spring maize. Hence, in this study, white transparent plastic film (WF), black plastic film (BF), and maize straw (MS) was used, and the results were compared with a non-mulched control (CK). The results showed that the mean soil temperature throughout the whole growth period of maize at the 5–15 cm depth under WF and BF was higher than under MS and CK, but under BF, it was 0.6 °C lower than WF. Compared with CK, the average soil water storage (0–200 cm) over the whole growth period of maize was significantly increased under WF, BF, and MS. WF and BF increased the soil water and temperature during the early growth stages of maize and significantly increased root/shoot biomass, root volume, LAI, LAD, and yield compared with MS. Higher soil temperatures under WF obviously reduced the duration of maize reproductive growth and accelerated root and leaf senescence, leading to small root/shoot biomass accumulation post-tasseling and to losses in yield compared with BF
