Many pastures in eastern Nebraska and surrounding areas have gradually decreased in productivity. Over a long period of heavy grazing, native warm-season grasses have been largely replaced with Kentucky bluegrass, other less desirable grasses, and broadleaf weeds. A program was started in 1949 to study the effectiveness of protection from grazing in changing the botanical composition and yield of a pasture where the predominant forage was Kentucky bluegrass. Several weed control treatments were included in this experiment to determine if mowing or spraying would hasten the return of more desirable forage. After weed control and differential grazing treatments had been …

A Mode Of Action Of Herbicides: Inhibition Of The Normal Process Of Nitrite Reduction, Lowell Klepper
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Herbicides were shown to interfere in the normal process of enzymatic nitrite reduction by the plant in photosynthetic and nonphotosynthetic plant tissues with little effect on nitrate reduction. This preferential inhibition caused nitrite to accumulate. The occurrence of free nitrite within the plant can help to explain the toxicity symptoms, nastic growth reactions, abnormal metabolism and rapid death due to herbicide action. This blockage of nitrite reduction was shown with all photosynthetic inhibitor herbicides tested and with numerous other herbicides. The effect was demonstrated using an in vivo assay, intact green plants and germinating seedlings. A basic in vivo method …
