Hard yellow maize is a crucial crop in Peruvian agriculture that plays significant role food security and livestock production. However, intensive fertilization practices agronomic management have negatively impacted soil health. To explore more sustainable agricultural technologies, researchers investigated solutions using microorganisms to enhance plant growth. This study assessed the synergistic effects of microbial inoculants mineral on INIA 619 Dekal B-7088 varieties’ yield nutritional quality. A split-plot design was employed, incorporating four inoculation treatments—no inoculant, Bacillus subtilis, Trichoderma viride, Pseudomonas putida—combined with levels 0%, 50%, 75%, 100%. The findings revealed subtilis boosted yields by 13.1% 55.5% B-7088. Additionally, combined 100% fertilization, increased protein content 47% carbohydrates 6% while maintaining quality 75% fertilization. Similarly, B-7088, total enhanced 54% fiber 27%. These results demonstrated could reduce up 25% sustaining high improving maize.

Introduction The formation of yield and quality in maize involves the accumulation substances such as starch, proteins, fats, which interact with water within kernel. Although temporal dynamics grain moisture its functional environmental determinants have been broadly demonstrated, we still do not a comprehensive understanding distribution phase Methods We investigated relationship between tissue structural traits, including embryo volume (EMBV), endosperm (ENDV), vitreous (VEV), floury (FEV), content different phases, bound water, semi-bound free kernels under cultivars, nitrogen application rates, soaking durations by combining low-field nuclear magnetic resonance (LF-NMR) X-ray microcomputed tomography (μ-CT) for kernels. Results results demonstrate that is major (57-82%) kernels, this proportion decreases prolonged duration. positively correlate to ENDV, VEV, EMBV, whereas correlates VEV descending order correlation coefficient. This indicates might penetrate through pedicel pericarp during soaking. Discussion Finally, suggested could be robust indicator predict study provides preliminary basis thereby opening up potential designing efficient production systems breeding cultivars well-suited mechanical harvesting.

Optimizing fertilization practices can reduce the application of chemical nitrogen fertilizers, thereby enhancing crop yield while mitigating environmental impacts. In 2021–2022, we conducted field experiments in Inner Mongolia region, evaluating effects different methods on sugar beet growth and productivity. A two-factor randomized complete block design was applied for with rates (0, 75, 150, 225, 300 kg ha−1, denoted as N0, N75, N150, N225, N300, respectively) primary factor (single basal application, S1; split S2) second factor. The results indicate that increasing significantly enhances leaf growth, chlorophyll content, dry matter accumulation, metabolism, yield. comparison a nitrogen-free treatment, N225S1 treatment improved development resulting an average increase 29.36% over two years. Notably, by optimizing root–shoot balance carbon–nitrogen N150S2 achieved root yields comparable to N225S1. Therefore, our study demonstrates maintain reducing fertilizer inputs, providing valuable insights sustainable cultivation Mongolia, main growing area China.

Context Prolonged monoculture of waxy corn ( Zea mays L. var. ceratina Kulesh ) exacerbates soil nutrient depletion and compromises structural integrity, concomitant with underutilization photosynthetically active radiation (PAR) resources. Objective Implementing cover cropping post-harvest can utilize residual environmental resources for quality improvement. Nevertheless, the agronomic consequences this practice on canopy architecture optimization resource allocation dynamics in subsequent growing seasons require systematic elucidation. Methods The regionally adapted cultivar Wannuo 2000 (W67×W68), predominantly cultivated northeastern China, was employed characterization. Three experimental treatments were established, including continuous control (CK), shamrock Trifolium pratense L.) rotation after harvest (ZT) rapeseed Brassica napus (ZB). Each treatment incorporated five nitrogen (N) application gradients (0, 60, 120, 180, 240 kg N ha − ¹) arranged randomized complete block design (RCBD) triplicate plots. Results Cover crops integration significantly enhanced productivity. Mean yields ZT ZB systems during 2022–2023 demonstrated 20.74% (8.88 ± 2.50 Mg −1 22.26% (8.99 3.12 increases respectively compared to CK. Remarkably, under 25% reduction scenarios, achieved 15.25% (44.58 6.28%) 20.67% (46.68 7.15%) improvements use efficiency (NUE) relative conventional practice. path analysis revealed synergistic interactions between crop incorporation management mediated through optimization. Specifically, leaf area index (4.56 0.69 m² m ²) elevated pre-silking content (132.61 26.33 g plant collectively drove post-silking biomass accumulation (134.88 26.85 remobilization efficiency. Conclusion integrated crop-nitrogen system both yield NUE benchmarks, demonstrating dual benefits conservation agricultural productivity enhancement. Implication This study establishes a theoretical framework provides empirical evidence sustainable intensification production systems.

Waxy corn is a special type of maize primarily consumed as fresh vegetable by humans. Nitrogen (N) plays an essential role in regulating the growth progression, maturation, yield, and quality waxy maize. A reasonable N application rate vital for boosting accumulation both carbon (C) grains, thereby synergistically enhancing grain quality. However, impact varying levels on dynamic changes metabolism, carbohydrate formation, anthocyanin synthesis purple kernels, well regulatory relationships among these processes, remains unclear. To explore effects rates kernels during filling, two-year field experiment was carried out using variety Jinnuo20 (JN20). This study examined different levels, specifically 0 (N0), 120 (N1), 240 (N2), 360 (N3) kg ha
