Background: Supplement of balanced nutrition is required for the growth and development of crops and humans, particularly essential amino acids, vitamins and minerals. The application of mineral micronutrient fertilizers to soil or plant leaves to increase micronutrient content in edible parts of crop. Therefore, this study is focused to evaluate the effect of agronomic biofortification with different nutrient levels on maize. Methods: A field experiment was conducted on sandy clayey loam soil during the Rabi season of 2020-21 Perambalur, Tamil Nadu to study the effect of agronomic biofortification through integrated nutrient management for improving maize (Zea mays L.) yield and quality under Cauvery delta condition. Two hybrids in main-plots both, QPM and non-QPM were sown by direct method on ridges at a spacing of 60 x 20 cm under split plot design (SPD) with 6 treatments of nutrient management in sub-plot combination under three replications. Result: The results revealed that the nutrient level treatments containing 50% RDF through NPK + 50% RDF through FYM with Fe and Zn as foliar application @0.5% conc led to highest growth and yield attributes, grain yield (8.52 tha-1) and stover yield (10.35 tha-1) and also resulted in maximum crude protein content (14.93%), starch content (63.85 mg g-1), Fe (36.25 mg kg-1) and Zn (29.35 mg kg-1) in maize grain. It was observed that Agronomic biofortification through integrated nutrient management enhanced the vegetative growth and yield components of non-QPM hybrid, whereas it improved the grain quality content of the QPM hybrid.

“…Despite a steady reduction in global dietary Zn deficiency in the last 20 years, more than 25% of the population in sub‐Saharan Africa (SSA) is still at risk of inadequate dietary Zn intake (Kumssa et al., 2015). While numerous experimental agronomic biofortification studies using Zn‐containing fertilizers have been conducted (e.g., Abdoli, Esfandiari, Mousavi, & Sadeghzadeh, 2014; Cakmak, 2008; Cakmak, Pfeiffer, & McClafferty, 2010a; Manzeke, Mtambanengwe, Nezomba, & Mapfumo, 2014; Manzeke et al., 2017; Zou et al., 2012), fewer studies have been conducted on maize ( Zea mays L.; e.g., Manzeke et al., 2014; Naveed et al., 2018; Zhang et al., 2013), the staple grain in most Southern African countries. Reducing Zn deficiencies in SSA is confounded by low fertilizer application (Jama & Pizarro, 2008; Kaizzi, Mohammed, & Nouri, 2017) and a scarcity of appropriate fertilizers (Mapfumo & Giller, 2001; Mtambanengwe & Mapfumo, 2005; Nezomba, Mtambanengwe, Rurinda, & Mapfumo, 2018).…”

Agronomic biofortification of crops with zinc (Zn) can be enhanced under increased nitrogen (N) supply. Here, the effects of N fertilizer on grain Zn concentration of maize (Zea mays L.) and cowpea (Vigna unguiculata L.) were determined at two contrasting sites in Zimbabwe over two seasons. All treatments received soil and foliar zinc-sulphate fertilizer. Seven N treatments, with three N rates (0, 45, and 90 kg ha −1 for maize; 0, 15, and 30 kg ha −1 for cowpea), two N forms (mineral and organic), and combinations thereof were used for each crop in a randomized complete block design (n = 4). Maize grain Zn concentrations increased from 27.2 to 39.3 mg kg −1 across sites. At 45 kg N ha −1 , mineral N fertilizer increased maize grain Zn concentration more than organic N from cattle manure or a combination of mineral and organic N fertilizers. At 90 kg N ha −1 , the three N fertilizer application strategies had similar effects on maize grain Zn concentration. Co-application of N and Zn fertilizer was more effective at increasing Zn concentration in maize grain than Zn fertilizer alone. Increases in cowpea grain Zn concentration were less consistent, although grain Zn concentration increased from 39.8 to 52.7 mg kg −1 under optimal co-applications of N and Zn. Future cost/benefit analyses of agronomic biofortification need to include information on benefits of agro-fortified grain, complex farmer management decisions (including cost and access to both N and Zn fertilizers), as well as understanding of the spatial and site-specific variation in fertilizer responses.Abbreviations: CRM, certified reference material; NR, natural regions; SSA, sub-Saharan Africa.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

Achat et al 61 demonstrated that organic matter, specifically carbon, as well as the N ratio in regard to carbon and the P ratio in regard to K-Ca-Mg, is one of the factors influencing remobilization in plants.…”

BACKGROUND Magnesium (Mg) has important effects on maize growth, and the application of Mg fertilizer with straw return inevitably has an impact on Mg absorption in maize. RESULTS A two‐year field trial was conducted to investigate the effects of Mg fertilizers with straw return on Mg accumulations, partitioning and remobilization in maize (Zea mays L.) in northeast China. The treatments included: (i) JM3 (straw + Mg fertilizer), (ii) JM0 (straw + no Mg fertilizer), (iii) WM3 (no straw + Mg fertilizer), and (iv) WM0 (no Mg fertilizer + no straw). The results showed that the highest Mg accumulation stage in maize was prominent between the tasseling stage (VT) and blister stage (R2), and JM3 treatment accumulated 13.3% and 26.6% more Mg on average than those of the WM3 and WM0, respectively. Magnesium remobilization in distinct organs was highest in JM3 and there were significant differences between treatments. The total contribution to the grain for the JM3 treatment was higher by 6.0% and 17.9% on average than those for the WM3 and WM0, respectively. The grain yield of JM3 treatment was 0.5% and 5.3% higher than that of WM3 and WM0, respectively. CONCLUSION Generally, these outcomes indicated that there was an interaction between Mg fertilizer and maize straw. The application of Mg fertilizer significantly promoted the accumulation, distribution to the maize organs, and the remobilization of Mg. The combination of straw return and Mg application further increased the accumulation of Mg in the grain. And all these lead to an increase in yield. © 2020 Society of Chemical Industry
