Abstract
Abstract Experiments were conducted at Lincoln, North Platte, and Alliance, Nebraska, during 1965 and 1966 to determine the effect of herbicides, herbicide incorporation, and rotary hoeing on ‘Nebraska 505’ sorghum [ Sorghum bicolor (L.) Moench.] grown in 50.8‐cm rows. Preplant soil incorporation and preemergence herbicide applications were superior to preemergence + shallow incorporation with a rotary hoe in weed control and grain yields. Postemergence rotary hoeing improved weed control and sorghum yields on herbicide treatments. The best treatments were atrazine (2‐chloro‐4‐ethylamlno‐6‐isopropylamino‐s‐triazine) at 2.24 kg/ha and atrazine norea [3‐(hexahydro‐4,7‐methanoindan‐5‐)y‐ll, l‐dimethylarea] at 0.84 + 1.68 kg/ha (1.12 + 2.24 kg/ha in 1965) + two rotary hoeings at Lincoln, atrazine at 2.24 kg/ha at North Platte, and rotary hoeings but no herbicide at Alliance. Only at Lincoln did sorghum yields on herbicide‐treated plots approach that on handweeded checks. On the low organic matter soils at North Platte and Alliance, atrazine injury limited sorghum yields.
