“…The NUE of maize was determined by coordinating the N uptake e ciency (NUpE) and the N utilization e ciency (NUtE) (Duan et al, 2023). In the present study, we found that the NUE and NUpE of SP were signi cantly higher than those of SM at the same nitrogen application level (Fig.…”

Straw return offers an effective way to achieve soil sustainability. However, there is a limited amount of research addressing the impact of nitrogen application and straw return method on the vertical distribution of crop canopy and nitrogen allocation. The experiment was based on a long-term eld experiment that started in 2011 and was conducted at the Halahai Comprehensive Experimental Station in Nong'an County, Jilin Province. Sampling was carried out in 2021 and 2022 to analyse the canopy distribution and nitrogen allocation of the maize hybrid Fumin 985 under two straw returning methods, no tillage with straw mulch (SM) and plow tillage with straw return (SP), and ve nitrogen application rates: 0 (N0), 90 (N90), 150 (N150), 210 (N210), and 270 kg N ha − 1 (N270). The present study indicated that under a nitrogen application rate below N150, the yield was on average 11.66% − 24.34% higher in SP than in SM. This difference was mainly attributed to the variation in 1000-grain weight. Furthermore, SP maintained a higher leaf area index (LAI) and total radiation interception rate (RIR) during the grain lling stage with the same nitrogen application rate compared to SM. It also signi cantly increased postowering dry matter accumulation by 8.87% − 69.26% compared to SM. Additionally, SP signi cantly improved the proportion of grain dry weight and led to an increase of 10.35% − 16.04% in 1000-grain weight compared to SM. Moreover, SM increased the relative nitrogen content in grain, which in turn improved nitrogen uptake e ciency (NUpE) and grain nitrogen use e ciency (NUE). Finally, SP demonstrated a synergistic enhancement in yield and NUE under lower nitrogen application rates than SM. In summary, the combination of SP with nitrogen fertilizer application proves to be an effective method to achieve high yield and high e ciency maize production compared to SM.

Background The mangosteen tree (Garcinia mangostana L.) is a very slow-growing tree that takes between 8 and 15 years before bearing its first fruits. This slow growth and late fruiting of the plant constitute a real obstacle to its adoption and its propagation in rural areas. In Côte d'Ivoire, these constraints have led to the limitation of cultivation to small farms belonging to a few producers, whereas it could constitute an alternative to the diversification of agricultural income and contribute to poverty reduction in rural areas. This study was therefore initiated with the aim of evaluating the effects of soil type and fertilizers on the agronomic parameters of mangosteen tree growth in order to contribute to the shortening of its vegetative phase. Results The results of this study showed the significant effect of soil type and fertilizers on mangosteen growth parameters. The evaluation of the effect of soil type and fertilizers on the agronomic performance of mangosteen showed that lowland soil promotes better plant growth. The growth rates recorded after 36 months of monitoring were 53.08 ± 7.30% in mangosteen trees grown on lowland soil and 41.51 ± 13.43% in those grown on forest soil.. Also, foliar and granular N-P-K fertilizers favored a shortening of the onset of fruiting from the 5th year of cultivation. Conclusions The results testified to the clear importance of the contribution of fertilizers in the management and the shortening of the juvenile phase of the mangosteen tree. Fertilizers based on foliar fertilizer and NPK have recorded remarkable performances by favoring a shortening of the entry into fruiting of mangosteen trees from the fifth year of cultivation.

“…This study showed that the yield changed with nitrogen application rate in a quadratic parabolic relationship, and the yieldincreasing effect slowed down with an increase in nitrogen application rate, which was in line with the diminishing returns effect. Moreover, excessive nitrogen application will reduce yield because it will affect crop nitrogen absorption efficiency, reduce nitrogen transport rate, and even affect root water absorption, resulting in a decreased yield [42,43]. Increasing the application of nitrogen fertilizer can enhance the water absorption capacity of the root system [44].…”

Residual film pollution and excessive nitrogen fertilizer have become limiting factors for agricultural development. To investigate the feasibility of replacing conventional plastic film with biodegradable plastic film in cold and arid environments under nitrogen application conditions, field experiments were conducted from 2021 to 2022 with plastic film covering (including degradable plastic film (D) and ordinary plastic film (P)) combined with nitrogen fertilizer 0 (N0), 160 (N1), 320 (N2), and 480 (N3) kg·ha−1. The results showed no significant difference (p > 0.05) in dry matter accumulation, photosynthetic gas exchange parameters, soil enzyme activity, or yield of spring maize under degradable plastic film cover compared to ordinary plastic film cover. Nitrogen fertilizer is the main factor limiting the growth of spring maize. The above-ground and root biomass showed a trend of increasing and then decreasing with the increase in nitrogen application level. Increasing nitrogen fertilizer can also improve the photosynthetic gas exchange parameters of leaves, maintain soil enzyme activity, and reduce soil pH. Under the nitrogen application level of N2, the yield of degradable plastic film and ordinary plastic film coverage increased by 3.74~42.50% and 2.05~40.02%, respectively. At the same time, it can also improve water use efficiency and irrigation water use efficiency, but it will reduce nitrogen fertilizer partial productivity and nitrogen fertilizer agronomic use efficiency. Using multiple indicators to evaluate the effect of plastic film mulching combined with nitrogen fertilizer on the comprehensive growth of spring maize, it was found that the DN2 treatment had the best complete growth of maize, which was the best model for achieving stable yield and income increase and green development of spring maize in cold and cool irrigation areas.
