“…in the second half of the grain-filling period (Borges et al, 2009) which corresponds well with our results with the Mn and Cu contents at the 2nd sampling (Tables II and III). The Zn uptake however was reduced in both years and in the first year Fe uptake was also reduced as compared with the first sampling, probably on the basis of the so-called dilution effect (Mengel & Kirkby, 2001).…”

“…These results confirmed the high demands of maize for zinc and iron with uptakes in the following order Fe Zn Mn Cu. Borges et al (2009) reported that the total amount of nutrients required to produce one ton of corn is: 0.019 to 0.02 kg Cu; 0.042 to 0.046 kg Mn; 0.100 to 0.194 kg Zn. In agreement with our findings, but not taking Fe into account, maize plants were found to accumulate nutrients in the aboveground parts as follows: ZnMn Cu.…”

Due to continuous single nitrogen fertilization, we hypothesized a built-up deficiency of micronutrients in crops that would limit plant growth and crop quality. In 2-year field experiments using urea-N fertilized grain maize (Zea mays L.), hybrid KWS 2376 at 0, 120 and 240 kg N ha (1 crop uptake of Zn, Mn, Cu and Fe was studied at DC 32, DC 61 and in the grain harvested. Micronutrient contents at DC 32 stage Á 1st node (aboveground phytomass) and DC 61 Á flowering (ear leaf) were all at levels indicative of adequate micronutrient supply to the crop. At both sampling occasions the Fe:Zn and Fe:Mn ratios were adequate implying that Fe did not inhibit the uptake of Zn and Mn. The application of nitrogen increased the Fe content at the 1st sampling in both years; in the second year the same was also the case for the Zn content. Nitrogen nutrition increased the contents of Mn and Fe at the 2nd sampling only in year 2; in the other treatments no changes were observed in the micronutrient contents. Micronutrient correlations in the grain were discovered between Zn and Mn contents and between Fe and Mn contents. In the second year the highest N-rate significantly increased the Fe and Zn content of the grain compared with the lower rates of nitrogen fertilization. Grain yields were not affected by the rate of nitrogen and ranged between 13.65 and 14.34 t ha (1 (1st year) and between 13.68 and 14.18 t ha (1 (2nd year). Nitrogen fertilization did not reduce the content of micronutrients in the plant or grain of maize. It is evident that the continuous single use of N fertilization so far has not resulted in a micronutrient deficiency of the plants limiting the nutrient density of the grain or reducing its quality.

“…These results are in agreement with Bender (2013), which reported that in the period before flowering only half of the total Cu accumulation has occurred. Maximum Cu extraction point determined by Andrade et al (1975b) was between 101 and 108 days after emergence, and Borges et al (2009) at 102 days after emergence. Confirmation of Cu extraction pattern extending to the end of the cycle indicates that, regardless of the hybrid used and the growing environment, ensuring conditions for satisfactory supply of this micronutrient, also during the grain filling stage of the crop, are important.…”

Introducing cultivars of high productive potential with adequate agronomic management has contributed to the increase of maize yield in Brazil. This study aimed to characterize the extraction and exportation of micronutrients by modern maize hybrids grown in no-tillage system in the Cerrado region (Brazilian Savannah) with two fertilization levels. We established two crop environments with differentiated levels of soil fertilization, use of products for seed treatment and leaf fertilization, in which four transgenic hybrids were grown. For each environment, we used an experimental design of randomized blocks with four replicates. There were eleven plant samplings during the crop cycle to quantify dry mass production and Cu, Fe, Mn and Zn extraction. Micronutrient uptake is increased when a hybrid with higher potential for biomass production grows in an environment with greater supply of nutrients. Uptake persists throughout the maize cycle, including during the final stages of the reproductive phase, showing late demand for the crop. On average, after tasseling, about 39, 50, 42, and 49% of the total Cu, Fe, Mn and Zn absorption still occurs, respectively. Total uptake of Cu, Fe, Mn and Zn are, respectively, around 8, 199, 58 and 40 g to produce a tonne of grain, from which 23, 5, 8, and 42% are exported by the harvest. Micronutrient uptake and exportation rates for the studied transgenic hybrids are lower than the ones previously reported in Brazil and in works abroad.

“…On a calcareous soil, B interacted with zinc (Zn) and antagonistically affected nutrient concentration and synergistically affected growth [15]. Minimum amounts of B accumulated in corn during initial growth stages and maximum accumulation was observed after 100 days of seedling emergence in two corn hybrids in Brazil while the total amount of B required to produce one ton of corn was 0.9 g [16]. However, B decreased P uptake and dry weight of corn genotypes [17], while a Ca application antagonized shoot B concentrations of four corn hybrids [18].…”

Boron (B) is an essential micronutrient needed for normal plant growth and development. To evaluate the response of corn to foliar B applications at V4-V6 (4-6 leaves with visible collars) and VT (tasseling) growth stages on fine textured soils, a field experiment was conducted at four sites from 2008 to 2010 in Northeast Missouri. The treatments included a non-treated control; V4-V6 applied B at 0.56, 1.12 and 2.24 kg·ha −1 ; and VT applied B at 0.28, 0.56 and 1.12 kg·ha −1 . Foliar B, applied at V4-V6 at 2.24 kg·ha −1 , resulted in higher yields than VT applications. No significant differences in yield were found for B applications at different timings for concentrations of 0.56 and 1.12 kg·ha −1. Boron applied at V4-V6 and 2.24 kg·ha −1 increased yield 0.29 Mg·ha −1 compared to the non-treated control. The B applications at VT increased ear leaf tissue B concentration compared to V4-V6 applications and non-treated control, but it had no significant effect on corn yields. No significant difference between B treatments was observed for grain oil, protein, starch or extractable starch concentration; severity of anthracnose stalk rot or common rust; and ear tip fill. The B application of 2.24 kg·ha −1 at V4-V6 decreased the severity of gray leaf spot, but increased the severity of northern leaf blight compared to the non-treated control. Boron applied at V4-V6 at 2.24 kg·ha −1 was the most beneficial timing and concentration evaluated in these fine textured soils. OPEN ACCESSAgronomy 2015, 5 2
