   Yield Estimates Harvest potatoes from several 10-ft sections of row, calculate the average wt. in lbs., then multiply by the following numbers to estimate approximate yield/acre in cwt.

Approximate Cwt/Acre = lbs/10 ft. x Multiplication Factor

 Row Width (in) Multiplication Factor 33 16.4 34 15.4 36 14.5

Seed Requirements

Approximate Cwt. of Seed Required to Plant an Acre Using 34-inch Rows
For 36-inch rows, multiply by 0.93

Potato Weights & Volumes

 1 lb./acre = 1.12 kilogram/hectare 1 kilogram/hectare = 0.892 lb./acre 1 cwt/acre = 0.112 metric tons/hectare 1 metric ton/hectare = 8.93 cwt/acre 1 bushel of potatoes = 53 lbs. 1 bushel = 1.244 cu ft = 35.2 liter 1 cu ft of potatoes = about 42 lbs. 1 cwt. of potatoes = 2.38 cu ft 42 lbs./cu ft = 672.5 kg/cubic meter 1 barrel = 11 pas = 165 lb. = 3.93 cu ft = 0.11 cu meter 1 short ton = 2000 lb. 1 metric ton = 2204.6 lb.
