Summary: Changes in biomass and nitrogen partitioning between leaves and stems in maize at the silking stage can affect the diagnosis of crop nitrogen status and fertilizer recommendations. The ratio of nitrogen concentration between leaves and stems plays a crucial role in nitrogen uptake and yield. This research provides valuable insights for improving current nitrogen diagnostic tools based on the nitrogen nutrition index.

Summary: The study investigates the effects of maize-bean intercropping on maize yield, protein yield, and soil nitrogen content. Varying bean density and nitrogen fertilization levels have limited impact on maize yield, suggesting the potential for further optimization of intercropping efficiency and reducing nitrogen fertilizer levels.

Summary: The combined application of straw mulch and biochar has significant effects on the growth and grain development of rainfed maize, improving plant morphology and yield. Higher biochar application rates have a positive impact on maize growth indices, such as plant height, stem diameter, and leaf area index.

Summary: Ethephon application in maize production can decrease grain yield, but it can also increase post-silking nitrogen remobilization and improve nitrogen use efficiency. Ethephon treatment also affects plant growth and nitrogen uptake.

Summary: Early nitrogen application on live cover crops or their residues can meet nitrogen demand and increase the yield of subsequent cash crops in tropical regions. The conventional method of nitrogen fertilizer application allows higher nitrogen recovery and maize yield.

Summary: The production of summer maize is significantly influenced by nitrogen sources, which affect root growth and distribution. Applying urea ammonium nitrate solution underwater and using fertiliser integration technology can improve root traits and nutrient uptake in summer maize, leading to higher grain yield. Rational application of this method increases nitrogen agronomic efficiency and nitrogen partial factor productivity.

Summary: The research shows that seminal roots can improve the acquisition of nitrogen and phosphorus in maize seedlings, with increased seed size associated with maize domestication possibly facilitating the increase in seminal root number. The study also suggests that the optimal number of seminal roots for nutrient acquisition in teosinte is constrained by its limited seed carbohydrate reserves.

Summary: This study evaluated the chemical composition, bioactivity, and growth characteristics of purple corn grown at two different altitudes in the Peruvian Andes. It was found that purple corn grown in the highland region had higher levels of antioxidant compounds and enzyme inhibitory activity.

Summary: This study investigated the effects of biochar and Arbuscular mycorrhizal fungi (AMF) on maize plants grown under saline stress. The combination of biochar and AMF showed the most significant improvement in plant growth under saline stress. The superior mitigating effect of biochar + AMF was attributed to its ability in improving soil nutrient content, enhancing plant nutrient uptake, and increasing the activities of antioxidant enzymes.

Summary: One-third of maize cultivation in Turkey is affected by Cu toxicity in agricultural lands due to abandoned opencast Cu-mine, but tea-derived biochar can effectively reduce Cu uptake in soil and improve maize tolerance to Cu without phenotypic retardation. The application of tea-BC shows potential agronomic benefits in remediating cationic Cu toxicity in mining-contaminated soils by enhancing soil-plant water relations and metabolic profile.

Summary: This study assessed the nutritional status of maize in critical growth stages by analyzing three different maize cultivars. The research showed significant response of maize to nitrogen fertilizers, especially during the period from the five-leaf stage to the full flowering stage. It also highlighted the importance of nitrogen and potassium content in determining the kernel weight in the ear.

Summary: Cells save energy during nitrogen starvation by selectively autophagocytosing ribosomes and degrading RNA. The preference of plant NRHs for nucleosides influences their breakdown and has consequences for plant growth and metabolism.
