How to Prepare Figures and Tables for an Agriculture and Nutrition Journal

How to Prepare Figures and Tables for an Agriculture and Nutrition Journal

Figures go into the manuscript as JPG or JPEG at 75 mm or 155 mm width and 300 dpi. Tables are placed after the references, use horizontal lines only, and are numbered in the order they are cited. Those are the requirements of this agriculture and nutrition journal, and almost every figure sent back for correction fails on resolution rather than on content.

Table or Figure? Decide Once

No agriculture and nutrition journal will print the same data twice, so never present it as both. Choose by what the reader needs to take away.

Use a table whenUse a figure when
Exact values matterThe shape of a relationship matters
Units or treatments differ across rowsA trend or a curve is the point
The reader may want to recalculateThe comparison is visual
There are many variables, few levelsThere are few variables, many levels

Composition of six varieties across four nutrients is a table. Yield response across five nitrogen levels is a figure. A yield response across five levels presented as a table of five numbers is a wasted table, and the same five numbers plotted and tabulated is a comment from the reviewer.

Why 300 dpi Matters, in Practice

Screen images are usually 72 to 96 dpi. Print needs 300. A chart copied from a spreadsheet and pasted into Word carries its screen resolution with it, which is why it looks acceptable on your monitor and blurred in the printed issue.

The fix is to export rather than copy. In a spreadsheet, save the chart as an image at the required size and resolution, then insert the file. In statistical software, export to a raster format at 300 dpi with the width set to 75 mm for a single-column figure or 155 mm for a full-width one.

Set the width before you export, not afterwards in Word. Dragging a small image larger inside the document does not add pixels; it enlarges the ones it has, which is precisely what produces the soft, fuzzy figures that come back for correction.

Designing a Figure Somebody Can Read

  • Axis labels with units — “Grain yield (t ha⁻¹)”, not “Yield”
  • Error bars, defined — say in the caption whether they are standard deviation, standard error or confidence interval, and give n
  • Legible at final size — print it at 75 mm and read it; if the axis numbers disappear, the font is too small
  • No decoration — no 3-D bars, no gradient fills, no shadows. They add ink and remove clarity
  • Distinguishable without colour — the print edition may be greyscale, so use pattern or marker shape as well as colour
  • Caption below the figure, table heading above the table

The greyscale point catches people out. Three lines in red, green and blue are three identical grey lines once printed. Use solid, dashed and dotted.

Building a Table That Passes Review

Every nutrition journal table needs four things: a self-descriptive heading, the number of replicates, a measure of dispersion, and units in the column headers rather than repeated in every cell.

Weak heading: “Table 2: Results”.

Usable heading: “Table 2: Grain yield, protein content and iron content of three pearl millet varieties under two irrigation regimes, kharif 2025 (means of four replications ± standard deviation)”.

The second heading lets the table stand alone. A reader who meets it out of context — in a database record, in someone's slide deck — knows what they are looking at, which is the test a caption has to pass.

On formatting: horizontal lines only, as this agriculture and nutrition journal requires. That means a line above the header, one below it, and one at the foot. No vertical rules, no grid, no shading.

Significance Letters and Footnotes

Where means are compared, mark them with superscript letters and explain the convention in a footnote: means in a column followed by the same letter are not significantly different at p = 0.05 by the named test.

Two habits worth keeping. Name the test in the footnote, not only in the methods, because the table gets read on its own. And apply letters within a column or within a row, never both at once — a table where the reader cannot tell which comparison the letters refer to is worse than a table with no letters.

Numbering and Citing Them in the Text

Number them in the order they are first cited, the same rule an agriculture and nutrition journal applies to references. Figure 1 is the first figure mentioned, wherever it eventually sits. The same applies to tables, and to references, which is one rule fewer to remember.

Cite every table and figure at least once in the text. An uncited figure is either unnecessary or evidence that a sentence went missing during editing, and reviewers ask about both.

In the text, point out what matters rather than narrating the whole table. “Iron content differed between varieties (Table 2), with the highest value in variety C” is enough. Walking through twelve numbers that are already printed below wastes the words the discussion needs.

Photographs and Plates

A nutrition journal accepts photographs, but field and laboratory images need a scale where size matters, and a caption saying what is shown, where and when. If a figure is a plate made of several images, subdivide it with upper-case letters and refer to them as Figure 1A, 1B and so on.

Do not adjust a photograph in ways that change what it shows. Cropping and overall brightness are acceptable and should be mentioned if substantial; selectively lightening one part of a gel or a plate is data manipulation, and a nutrition journal that screens submissions will treat it as such.

The Three Figures That Should Not Exist

Some figures are wrong before any question of resolution arises.

The pie chart of five percentages

Human eyes compare angles badly. Five slices at 24, 21, 20, 19 and 16 per cent are indistinguishable in a pie and obvious in a bar chart or, better, in one line of text. Pie charts survive in presentations and rarely earn their space in a nutrition journal paper.

The bar chart with two bars

Two means with error bars occupy a quarter of a page to convey what a sentence conveys in one line: control 3.42 ± 0.18, treatment 4.18 ± 0.21 t ha⁻¹, p < 0.01. Save the space for a figure that shows something a sentence cannot.

The figure whose caption tells you nothing

“Figure 3: Effect of treatments” forces the reader back into the methods to decode the axis. A caption should name what is plotted, the units, the site and season, and what the error bars are. Captions are read far more often than the paragraph that cites them.

A Check Before You Submit

  1. Is any data set present as both a table and a figure?
  2. Is every figure 300 dpi at 75 mm or 155 mm width?
  3. Does every axis have a label and a unit?
  4. Do error bars have a definition and an n?
  5. Would the figure survive greyscale printing?
  6. Does every table have a self-descriptive heading, n and dispersion?
  7. Horizontal lines only?
  8. Is every table and figure cited in the text, in numerical order?

Frequently Asked Questions

What figure resolution does this agriculture and nutrition journal require?

300 dpi, at 75 mm width for a single-column figure or 155 mm for a full-width one, supplied as JPG or JPEG within the Word file. Set the size before exporting rather than resizing afterwards.

Where do tables go in the manuscript?

After the references, each with a self-descriptive heading, using horizontal lines only. They are numbered in the order they are first cited in the text.

Can I use colour figures?

Yes, but design them so they still work in greyscale, since the print edition may not carry colour. Use different line styles or marker shapes as well as different colours.

Should error bars show standard deviation or standard error?

Either, provided you say which in the caption and give the number of replicates. What causes confusion is an unlabelled error bar, because standard error bars are smaller and look more favourable than standard deviation bars from the same data.

How many tables and figures should a paper have?

As many as carry information the text cannot, within the 15-page limit. Papers that arrive with nine tables usually have three that matter and six that belong in supplementary material or nowhere.

My figure looks fine on screen but the editor says it is low resolution. Why?

Almost always because it was copied and pasted rather than exported. A pasted chart keeps its screen resolution of around 96 dpi. Export it from the original application at 300 dpi and insert the file instead.
