Cotton ( Gossypium sp.) growers in recent years have been changing from planting cotton by drill‐planting and thinning to planting to a stand. Much planting to a stand is done by hill‐dropping seed. This study was initiated to compare lint yield of ‘Pima S‐4’ cotton ( G. borbadense L.) when drill‐planted and thinned and when hill‐dropped at 23‐cm spacing. There were three population levels, 1, 2 and 3 plants/hill, for hill‐dropped and comparable plant populations for drill‐planting and thinning. There were no significant differences in lint yield between hill‐dropping and drill‐planting in 3 years.
