Perennial ryegrass staggers is poisoning by peramine, lolitrem B, and other toxins that are contained in perennial ryegrass (Lolium perenne), and produced by the endophyte fungus Epichloë festucae which can be present in all parts of the grass plant, but tends to be concentrated in the lower part of the leaf sheaths, the flower stalks and seeds.
The Ohio River at Cairo is 281,500 cu ft/s (7,960 m 3 /s); [1] and the Mississippi River at Thebes, Illinois, which is upstream of the confluence, is 208,200 cu ft/s (5,897 m 3 /s). [66] The Ohio River flow is greater than that of the Mississippi River, so hydrologically the Ohio River is the main stream of the river system.
The results show that planting more pounds per acre of rye increased the cover crop's production as well as decreased the amount of weeds. The same was true when scientists tested seeding rates on legumes and oats; a higher density of seeds planted per acre decreased the amount of weeds and increased the yield of legume and oat production.
The Robert C. Byrd Lock and Dam, formerly the Gallipolis Lock and Dam, is the 10th lock and dam on the Ohio River, located 280 miles downstream from Pittsburgh.There are 4 locks: one for commercial barge traffic, 1,200 feet long by 110 feet wide; the auxiliary lock is 600 feet long by 110 feet wide; and there are 2 smaller parallel locks.
A seed rate of about 100 kg of seed per hectare (2 bushels per acre) is typical, though rates vary considerably depending on crop species, soil conditions, and farmer's preference. Excessive rates can cause the crop to lodge, while too thin a rate will result in poor utilisation of the land, competition with weeds and a reduction in the yield .
Downtown Huntington, West Virginia, during the Great Flood of 1937. The Ohio River flood of 1937 took place in late January and February 1937. With damage stretching from Pittsburgh, Pennsylvania, to Cairo, Illinois, 385 people died, one million people were left homeless and property losses reached $500 million ($10.2 billion when adjusted for inflation as of September 2022).
