Summary: The study was conducted to investigate the effects of plastic-film mulch on the remobilization of biomass and nutrients accumulated in the presilking stage to grain during the grain-filling period. The results showed that plastic-film mulch increased the translocation to the grain of postsilking assimilates and presilking nitrogen and phosphorus accumulated in vegetative organs. In hydrothermally limited environments, maize generally does not remobilize presilking assimilates but does remobilize presilking nitrogen and phosphorus in vegetative organs to the grain during grain filling.

Summary: Region-specific guidelines for maize management are essential in the US Great Plains. This study aimed to define maize yield environments, explore optimal planting date and hybrid maturity combinations, and identify different windows for maximizing yields. Historical weather data from 70 sites were used to analyze maize field dataset and simulate yields using the APSIM model. Results showed that long-maturing hybrids achieved greater yields, while late planting increased stability in central environments. Short-season hybrid maturities allowed for anticipation of physiological maturity date without yield penalties. The study suggests adopting region-specific guidelines to optimize yield and intensify maize-based farming systems.

Summary: This study conducted field trials to understand the mechanism of dry matter and nitrogen partitioning and its translocation during post-anthesis period on different sowing dates for winter barley production in the Pannonian Plain. The results showed that early sowing dates led to higher accumulation and translocation of dry matter and nitrogen in developing grain. The contribution of pre-anthesis dry matter translocation to grain yield varied among cultivars and different sowing dates. To achieve high yielding barley production in the Pannonian Plain, barley growers and breeders should focus on medium early barley genotypes adapted to early sowing.

Summary: Cotton production efficiency in arid climates is constrained by low nitrogen utilization rate and high nitrogen application rate. Allocating more nitrogen to late application can alleviate these issues and improve plant growth and yield. A three-year field experiment showed that late nitrogen application narrowed plant width, increased canopy light transmittance, extended boll growth period, improved defoliation, and increased seed cotton yield. Therefore, adopting a late nitrogen application strategy can be an efficient fertilizer management approach in arid areas.

Summary: The growth, organ development, and yield formation of maize are controlled by biomass and phosphorus partitioning and remobilization processes. There is a lack of detailed data for modeling modern maize cultivars. The study found that the leaf-senescence rate of Zhengdan 958 is lower, allowing post-silking photosynthesis to meet grain biomass demand. Despite the higher post-silking P uptake, a portion of leaf and stem P accumulated pre-silking is remobilized into grain.

Summary: Deficiencies in secondary nutrients, such as calcium, magnesium, and sulfur, disrupt the nitrogen balance in crop plants and lower overall yield. This hypothesis was analyzed based on the physiological functions of these nutrients and their relation to nitrogen uptake and utilization in plants. The management of calcium and magnesium levels in the soil, as well as the timing of application, can significantly impact nitrogen uptake and crop growth. Using secondary nutrients can improve fertilizer efficiency and increase yield while reducing costs and environmental risks.

Summary: Substituting organic fungicides with inorganic fungicides (phosphites, Phi) does not affect the efficiency of nitrogen fertilizer in winter wheat. Two growing seasons were tested, and the results showed that increasing the frequency of phosphites instead of fungicides led to a decrease in grain yield due to disturbances in the nitrogen status and increased wheat infestation by pathogens.

Summary: The production of alfalfa in nutrient-deficient soils relies on the use of fertilizers. An experiment conducted on loamy sand soil with low levels of available Ca and K confirmed this hypothesis. Gypsum application increased yield, with the highest yield obtained from P60K120 fertilizer. K content in the first cut of sward use was a reliable yield predictor. Micronutrient uptake was positively affected by gypsum, especially for manganese. Optimization of alfalfa production in nutrient-poor soils should consider micronutrient supply and the limitations of high doses of basic fertilizers.
