Summary: A modified sowing pattern with wider seedling strips has been found to improve the nitrogen use efficiency of winter wheat, especially in terms of enhanced nitrogen uptake from the soil. However, the effects of this sowing pattern on root size, N-15-uptake efficiency, and N uptake from different soil depths have not been clarified yet.

Summary: This study evaluated the impact of nitrogen (N) application timings on winter wheat grain yield and protein. The results showed that in-season N applications increased grain yield and protein, and delaying N application until the late-vegetative phase had no negative impact on yield. Plants were able to recover from N deficiency.

Summary: Increasing grain density is essential for controlling nitrogen-use efficiency in winter wheat. Protection with fungicides and foliar fertilization during key stages of yield formation can enhance grain yield by increasing grain density. This hypothesis was verified in a field experiment, demonstrating the significant impact of fungicide protection and nitrogen doses on grain yield. The study also revealed the positive correlation between grain yield and grain density.

Summary: This study aimed to investigate the relationship between deep roots in winter wheat and drought tolerance, and how this relationship is affected by genotype and nitrogen fertilization. The study found that deep roots were correlated with higher grain yield, uptake of water and nitrogen from deeper layers, and tolerance to drought. Therefore, breeding efforts should consider enhancing deep rooting for more climate resilient crops.

Summary: Improper nitrogen fertilizer application in winter wheat production in the North China Plain can lead to reduced nitrogen use efficiency and increased risk of non-point pollution. The study calibrated the DSSAT-CERES-Wheat model and found that 180 kg ha(-1) was the optimal nitrogen application rate for drip-irrigated winter wheat production in the NCP.

Summary: Improper optimization of nitrogen rates and ratios can negatively impact grain yields and photosynthetic characteristics of winter wheat. Applying 225 kg/ha of nitrogen and using a ratio of 6:4:0:0 at sowing, jointing, flowering, and grain filling stages can effectively enhance photosynthesis and other physiological characteristics of winter wheat.

Summary: Nitrogen is crucial for crop production, affecting wheat yield and grain quality. This study found that the interaction between nitrogen and fungicide had a synergistic effect on grain yield, with significantly higher yields when both were applied. Additionally, newer wheat cultivars showed improved performance in agronomic traits compared to older cultivars, indicating the importance of cultivar selection for optimized resource use efficiency.

Summary: Nitrogen supply and seed rate have significant effects on wheat growth, yield, and nitrogen use efficiency. Increasing nitrogen levels and decreasing seed rate can improve photosynthetic rate, stomatal conductance, chlorophyll content, and enzyme activities. A combined treatment of nitrogen at 235 kg/ha and seed rate at 180 kg/ha resulted in the highest grain yield and nitrogen use efficiency.

Summary: The aim of this study was to evaluate the effect of fungicide application and nitrogen top-dressing rate on the yield and grain quality of winter wheat. The results showed that the use of fungicides increased or decreased grain yield depending on the year, while an increase in nitrogen top-dressing rate consistently increased yield. Fungicide application had a significant effect on grain weight and volume weight, while nitrogen top-dressing rate affected protein content, wet gluten and starch content, and Zeleny index.

Summary: In a conventional no-tillage corn/soybean rotation system with cover crops in eastern South Dakota, different cover crops have varying effects on soil nutrient dynamics, biomass, nutrient uptake, and corn yield. While oat, vetch, and a combination of cover crops can increase corn yield in some site-years, the effects vary among different site-years.

Summary: Winter rye biomass and composition, including carbon:nitrogen ratios and concentrations of structural carbohydrates, have significant impacts on decomposition rates, nutrient cycling, and cash crop growth. Higher seeding rates and delayed termination dates can increase rye biomass and nutrient concentrations, but also result in higher C:N ratios and concentrations of hemicellulose and cellulose. Lower seeding rates can potentially cycle nutrients faster without limiting biomass production potential.

Summary: This study investigated the nutrient requirements and effects of fertilization on the soil properties and growth status of Erythropalum scandens seedlings through a series of pot experiments. The results revealed that E. scandens seedlings have a stronger sensitivity to nitrogen levels, and excessive fertilization can lead to soil acidification. Proper fertilization treatments can promote better growth status of the seedlings.

Summary: The study examined the effects of growth media made of peat and different domestic materials on tomato nutrition, growth, and yield as an alternative to cocopeat in Turkiye. It was found that using vermicompost and its mixtures with peat as growth media resulted in the highest leaf and fruit nutrient concentrations. The highest fruit yields and biomass weights were obtained with solely peat and 1:1 peat + vermicompost medium. Peat-containing growth media, especially peat + vermicompost mixtures, can be used as alternatives to cocopeat in soilless tomato cultivation.
