Variety Trial Comparison Sheet

A free printable variety trial sheet — one crop, several varieties side by side, with the number sown, how many came up, yield, taste and keeping notes and a grow-again column.

First page of the Variety Trial Comparison Sheet — Turn a vague sense that one variety did better into something you can read back in January when the seed order is due.

What this sheet is for

Turn a vague sense that one variety did better into something you can read back in January when the seed order is due.

Who it is for

Growers trying more than one variety of the same crop — allotment holders, seed savers, market gardeners and anyone curious enough to compare properly.

How to use it

  1. Use one sheet per crop, and note at the top what you kept the same between varieties.
  2. Write in the number sown and count what came up yourself rather than copying the packet.
  3. Record yield in whatever unit you already use for that crop.
  4. Fill in taste and keeping after eating and storing, not at picking.
  5. Tick the grow-again column while the comparison is still fresh.

What is on the sheet

One page, top to bottom:

Printed under the title: One crop, several varieties, side by side — sown the same way and judged on what you actually counted, weighed and ate, so next year's order is a decision rather than a guess.

Same treatment, different varieties. A trial only tells you something if the varieties get the same treatment. Note at the top what you held the same — bed, sowing date, watering — and keep the germination and yield columns to figures you counted or weighed yourself.

Write-on lines: Crop · Season or year · Bed / plot · Held the same

Varieties — germination is the count you made, not the packet's claim

Table, 8 rows: Variety · Supplier · Sown · Sown (no.) · Came up · First picked · Yield · Taste · Keeps · Again

Ruled lines: Notes — how the trial was run, anything that spoiled the comparison

Questions

Why not print the germination rate from the packet?

Because the packet figure was measured under laboratory conditions on a different batch, and it is not what your bed did. Counting what actually came up is the whole point of a trial.

How many varieties make a fair comparison?

As many as you can give the same treatment. Two well-matched rows tell you more than six varieties scattered about the plot in different soil and shade.
