Summary: This study investigated the effects of maize-soybean intercropping on nitrogen uptake, yield, utilization efficiency, and nitrogen assimilatory enzymes of maize crops under different nitrogen fertilization conditions. The results showed that intercropping at the optimal nitrogen rate significantly increased maize grain yield, residue yield, and 100-grain weight in both years. Intercropping also improved nitrogen content and uptake, as well as the activities of nitrogen assimilatory enzymes. These findings highlight the potential of intercropping for enhancing nitrogen status and use efficiency in maize crops, supporting sustainable agricultural production.

Summary: The study aimed to improve the nitrogen recovery efficiency (NRE) of maize by applying a balanced ratio of ammoniacal-nitrogen (NH4+-N) and nitrate-nitrogen (NO3--N) (1:1), and to assess the economic impacts of these fertilizers on maize productivity. Field studies were conducted in Sahiwal, Pakistan for three years, along with multi-location field experiments in farmers' fields. The results showed that the combination of Sarsabz nitrophos (NP) and calcium ammonium nitrate (CAN) increased maize grain yield by up to 30% compared to other fertilizer combinations, while also increasing total N and NO3--N concentrations in soils. Overall, the combined application of NP and CAN improved the NRE and net return of maize.

Summary: Global warming is expected to enhance crop nitrogen absorption capability and change nitrogen fertilizer input. The impacts of warming and nitrogen application on winter wheat growth, yield and nitrogen use efficiency are still unclear. In a 4-year field experiment, night-time warming shortened the vegetative growth period of winter wheat by 8.3 days but prolonged the reproductive growth period by 6.7 days. Warming increased winter wheat yield by increasing the number of spikes and grains per spike.

Summary: High temperature generally leads to reduced crop yield, and the concurrent precipitation plays a role in regulating this impact. However, the specific effects of precipitation modulation on crop yield response to global warming have not been extensively studied. This research examines the role of concurrent changes in precipitation in modulating global maize yield response to temperature increase. The findings reveal a negative impact of precipitation on maize yield sensitivity to temperature. Under warming scenarios, global maize yield is projected to decrease significantly, with the contribution of precipitation modulation being a crucial factor.

Summary: Excessive application of nitrogen fertilizer in winter wheat cultivation in the North China Plain leads to nitrogen loss and poor use efficiency. Drip fertigation is an effective method for improving nitrogen use efficiency and reducing losses, but its performance is limited by poor nitrogen scheduling. A two-year field experiment was conducted to evaluate the effects of different split urea applications on winter wheat growth, development, and yield. The results showed that the 50%-50% split fertigation and single application of slow-release fertilizer significantly influenced wheat grain yield and water use efficiency.

Summary: Chemical fertilizer overuse poses a severe threat to the environment by contaminating soil and water resources. In order to address this issue, optimizing nitrogen fertilizer application in winter wheat through various irrigation scheduling is a potential solution. A two-year field experiment demonstrated that applying nitrogen equally in splits at basal-top-dressing rates can be an effective and economically competitive alternative to costly slow-release fertilizers for drip-irrigated winter wheat cultivation. The I45N50-50 treatment showed the highest grain yield, aboveground biomass, net photosynthetic rate, and chlorophyll parameters, suggesting its suitability for promoting wheat production in the North China Plain.

Summary: Plastic film mulching for cotton production in Xinjiang, China has led to high levels of plastic residues in the soil, causing negative impacts on the soil environment and ecosystem. A study compared the performance of drip irrigation with film mulching (FMDI) and drip irrigation without mulching (WMDI) patterns on cotton growth, yield, and economic profits. Results showed that cotton yield was 26.21% lower under WMDI compared to FMDI. However, the WMDI pattern presented greater interannual stability and reduced costs of plastic film and fertilizer application. Despite obstacles, the WMDI pattern is a viable method to achieve sustainable cotton production and reduce plastic pollution in Xinjiang and similar regions.
