Size codes, explained

Before a single fruit is packed, its diameter decides which market it can go to. Here is how the international size scale for citrus actually works.

Wind scar and oil spotting: two blemishes you can plan around

Leggi Water and climate

Water, heat and fruit size: timing is everything

Deficit irrigation can save a fifth of the water without hurting yield, or cost a sixth of the crop. The difference is when it happens.

Leggi Sampling

How many fruit do you need to measure?

A size estimate is only as good as the sample behind it. Statistics gives a clear answer, and it is more than most scouts measure.

Leggi Yield

Estimating yield before harvest

Counting fruit on the tree is harder than it looks, because a third of the crop is hidden. Here is what research says about doing it well.
