Plant Spacing
Calculating Plant PopulationCalculating Plant Population Space per plantSpace per plant
(Row width x In Row)/144(Row width x In Row)/144 Ex. (40 x 22)/144 = 880/144 = 6.111111 Ex. (40 x 22)/144 = 880/144 = 6.111111
Sq ft per acre = 43560Sq ft per acre = 43560 43560/space per plant43560/space per plant
43560/6.111111 = 7128 plants per acre43560/6.111111 = 7128 plants per acre
