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 Nitrogen Application Enhances Sugar Beet (Beta vulgaris L.) Productivity by Modulating Carbon and Nitrogen Metabolism

Agronomy, Journal Year: 2025, Volume and Issue: 15(5), P. 1142 - 1142

Published: May 7, 2025

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.

Nitrogen Level Impacts the Dynamic Changes in Nitrogen Metabolism, and Carbohydrate and Anthocyanin Biosynthesis Improves the Kernel Nutritional Quality of Purple Waxy Maize

Plants, Journal Year: 2024, Volume and Issue: 13(20), P. 2882 - 2882

Published: Oct. 15, 2024

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

Synergy Between Microbial Inoculants and Mineral Fertilization to Enhance the Yield and Nutritional Quality of Maize on the Peruvian Coast

Applied Microbiology, Journal Year: 2024, Volume and Issue: 4(4), P. 1757 - 1775

Published: Dec. 21, 2024

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.
