Abstract

Experiments were conducted at Lincoln, North Platte, and Alliance, Nebraska, during 1961 and 1962 to determine the effect of tillage, atrazine, hand-weeding, and row spacings on RS 501 sorghum and weed yields. Combinations of tillage, narrow row spacings, and preemergence 2-chloro-4-ethylamino-6-isoproplyamino-s-triazine (atrazine) treatments gave more dependable weed control than any one alone. Sorghum yields increased and weed yields decreased with tillage and atrazine treatments. Preemergence atrazine applications as low as 1 lb/A gave higher sorghum yields and lower weed yields than postemergence atrazine applications of 2 to 4 lb/A. Preemergence atrazine applications should be reduced on lighter soils because atrazine gives more effective weed control and increased sorghum injury on such soils. There was a 1 bu/A decrease in sorghum yield for each 50 lb/A of weeds present.
