Features

Length and width. That's the input.

Enter your bed size and the area appears as you type. Beds are straight, so numbers come first.

Pick the crop, see the plant count

21 vegetables, all from published agricultural guidance. Spacing fills in automatically and the plant count appears at once.

Official rates, converted for your garden

Every fertilizer rate in Japan is written in kg per 10 ares — that's 1,000 m². Your bed is a few square metres. RowYield does the hundredfold conversion and shows the working.

Crop-specific warnings where too much nitrogen does harm

Sweet potatoes run to vine if over-fed. Broccoli develops hollow stem. Legumes fix their own nitrogen. RowYield names the risk and the source.

Harvest dates and yields, where the data exists

For one-off crops like cabbage, a weight range. For long-harvest crops like tomatoes, only the window and the weekly pace — the total swings too much to state as a number. Where no figure exists, the app says so.

Learn from your garden

Record what you actually harvest. After two seasons, your own numbers take over — with the published figures kept alongside.
