How it's calculated
Grain lb/ac = heads per acre × seeds per head ÷ seeds per pound. Heads per acre = heads per foot × (43,560 ÷ row spacing in feet). Divide pounds by 56 (the weight of a bushel of sorghum) for bu/ac.
Seeds per head is the most variable input — count several heads and average; drought-stressed heads may hold 800–1,200 seeds while a full head runs 2,000+.
Row Wise tracks grain sorghum vigor and yield potential from satellite all season, and flags moisture stress before it costs you bushels.

How many pounds are in a bushel of grain sorghum?
A bushel of grain sorghum weighs 56 pounds at market moisture (about 14%).
How do I count seeds per head?
Thresh a few representative heads by hand and count, or estimate from head size. Averaging 5–10 heads across the field gives a far better number than a single head.
What is a typical grain sorghum yield?
Dryland milo often runs 40–100 bu/ac depending on rainfall; irrigated or high-rainfall fields can top 130 bu/ac. This tool lets you plug in your own counts rather than guess.
