The improper application of phosphorus (P) fertilizers not only leads to resource wastage and environmental concerns but also disrupts the normal growth yield formation maize. This study aims explore effects varying P rates on growth, yield, photothermal response characteristics, accumulation dynamics, recovery efficiency (PRE) in summer maize, which provides a theoretical foundation for efficient scientific fertilizers. Field experiments were conducted over two growing seasons (2021−2022) Wen County, Henan Province, with set at 0, 30, 60, 90, 120 kg·P2O5·ha−1. At maturity, maize its components quantified. During key stages—jointing, tasseling, silking, grain filling—plant height, leaf area, Soil Plant Analyzer Development (SPAD) value, fraction photosynthetically active radiation (FPAR), canopy temperature, acid phosphatase activity (ACP), measured. results indicated that initially increased application, peaking an average increase 7.92–15.88%, before decreasing. optimal determined be 113 kg·P2O5·ha−1 68 kg·P2O5·ha−1, respectively. significantly lowered temperature ACP while increasing SPAD value FPAR 90 Logistic regression analysis revealed enhanced maximum (Vmax) mean (Vmean) rates, as well total accumulation. Moderate improved absorption various plant tissues promoted transfer grains. However, PRE, partial factor productivity from fertilizer (PPFP), agronomic (PAE) declined higher rates. In conclusion, fertilization utilization, optimized characteristics across different stages. Based these findings, recommended rate is between 70 110

Applying animal effluent/digestate to forage crops can improve the sustainability of intensive livestock husbandry. Organic phosphorus (P) forms, in particular phytic acid (InsP6) present effluent/digestate, would benefit from an effective uptake and assimilation by thus representing alternative mineral P fertilization controlling losses water system. A maize (Zea mays L.) traditional Italian population (VA572), bred before widespread diffusion crop chemical fertilization, a modern commercial hybrid (P1547) were used this study investigate their ability growing soilless medium using (Po) vs phosphate (Pi) as sources 28-day experiment.

Phosphorus (P) is an essential nutrient for crop growth, making it important maintaining food security as the global population continues to increase. Plants acquire P primarily via uptake of inorganic phosphate (Pi) in soil through their roots. Pi, which usually sequestered soils, not easily absorbed by plants and represses plant growth. have developed a series mechanisms cope with deficiency. Moreover, fertilizer applications are critical maximizing yield. Maize major cereal cultivated worldwide. Increasing its P-use efficiency optimizing maize production. Over past two decades, considerable progresses been achieved research aimed at adapting varieties changes environmental supply. Here, we present overview morphological, physiological, molecular involved acquisition, translocation, redistribution combine advances Arabidopsis rice, better elucidate progress nutrition. Additionally, summarize correlation between abiotic stress responses. Clarifying relevant improving absorption use can guide future on sustainable agriculture.

ABSTRACT Phosphorus (P) is an essential macronutrient for plant growth and development. Vacuoles play a crucial role in inorganic phosphate (Pi) storage remobilization plants. However, the physiological function of vacuolar efflux transporters Pi remains obscure. Here, we identified three ZmVPE genes ( ZmVPE1 , ZmVPE2a ZmVPE2b ) by combining them with transcriptome quantitative real‐time polymerase chain reaction (PCR) analyses, showing relatively higher expression older leaves than younger maize. Moreover, s was triggered deficiency abscisic acid. ZmVPEs were localized to membrane responsible efflux. Compared wild‐type, from enhanced ‐overexpression lines. zmvpe2a mutants displayed increase total P concentrations leaves, but decrease leaves. In rice, impaired osvpe1osvpe2 double mutant OsVPE plants, suggesting conserved functions VPEs modulating homeostasis crop Taken together, our findings revealed novel mechanism underlying mediated transporters, facilitating development Pi‐efficient

Abscisic acid (ABA) and jasmonic (JA) are important plant hormones in response to drought stress. We have identified that ZmHsf28 elevated ABA JA accumulation confer tolerance maize; however, the underlying mechanism still remains elusive. The knockout line zmhsf28 is generated confirm positive role of response. Multiple approaches combined reveal protein interaction among ZmHsf28, ZmSnRK2.2 ZmJAZ14/17, which form a regulatory module mediate maize through regulating key biosynthetic genes ZmNCED3 ZmLOX8. Upon stress, plants exhibit weaker than WT with slower stomatal closure more reactive oxygen species accumulation. interacted physically, resulting phosphorylation at Ser220, enhances binding heat shock elements ZmNECD3 ZmLOX8 promoters subsequent gene expression. Meanwhile, ZmMYC2 upregulates expression acting on G-box its promoter. Besides, ZmJAZ14/17 competitively interact interfere between ZmSnRK2.2, blocking impairing downstream regulation. ZmSnRK2.2-ZmHsf28-ZmJAZ14/17 regulate coordinating signaling, providing insights for breeding improve resistance maize.
