Effect Of Topping Time On Dark Tobacco Yield, Bill Maksymowicz
Effect Of Topping Time On Dark Tobacco Yield, Bill Maksymowicz
Agronomy Notes
When the terminal bud is removed from tobacco by topping, a number of changes are triggered in the plant: increased root growth, nicotine synthesis, improved drought tolerance, and leaf expansion and increased thickness. These changes are affected by topping time; generally there will be less crop response to topping as topping is delayed. The most important changes, from a producer's perspective, are continued leaf expansion and thickening, with a commensurate improvement in quality and increase in yield. Topping at the proper time of plant development is often difficult on a field scale since uneven crop growth, particularly when tobacco is …
Sucker Control Performance In Dark Tobacco, Bill Maksymowicz
Sucker Control Performance In Dark Tobacco, Bill Maksymowicz
Agronomy Notes
Poor sucker control adversely affects tobacco yield and quality. Suckers serve as a "sink" for nutrients and dry matter that otherwise would go to the expanding leaves intended for harvest, resulting in lower yields. Hand removal of large suckers can cause leaf damage, and failure to remove suckers may result in spoilage during the curing process, resulting in lowered quality. Use of chemical sucker control measures used in burley production can produce lower yields or W1desirable cured leaf color of dark tobacco. These studies were conducted to compare the effects of recommended sucker control practices for dark tobacco with systems …

A Survey Of The Content Of Some Heavy Metals In Soil And Corn Grain In The Pond And Lower Green River Bottoms, Kenneth L. Wells, Greg Henson, George Kelley
Agronomy Notes
Corn is intensively grown along the Green and Pond Rivers in McLean, Hopkins, and Webster Counties, Kentucky, representing a major source of income to producers in those areas. However, producers in McLean County have experienced poorer corn production than expected for many years. This has been observed more on the Pond River bottoms and the Green River bottoms below the confluence of the Pond than upstream on the Green above the Pond. Some producers have speculated that their poor production may be associated with chemical pollution from the Pond River and/or nearby industrial sources. On this basis, an assumption was …
Reduced Scepter Rates For Broadleaf Weed Control In Soybean, D. S. Jones, H. Lin, M. V. Kane, Larry J. Grabau
Reduced Scepter Rates For Broadleaf Weed Control In Soybean, D. S. Jones, H. Lin, M. V. Kane, Larry J. Grabau
Agronomy Notes
Public agencies are placing greater scrutiny on herbicide applications by farmers. For example, the corn herbicide atrazine is now classified as a restricted use pesticide, with limits placed on allowable rates. While soybean growers may share some of this concern for the environment, rate reduction is more likely to be attractive for economic reasons. Some growers are already cutting back on herbicide rates. For example, Missouri data shows that the average application rates for soybean herbicides were only 75% of the labelled rate. While reduced rates might save growers money, and may be kinder to the environment, there is a …
Hybrid Variation For Yield, Crude Protein, Feed Value And Percent Lysine Of Corn Grown In The 1991 Kentucky Hybrid Corn Performance Test, C. G. Poneleit, K. O. Evans, Michael Collins, D. O. Liptrap
Hybrid Variation For Yield, Crude Protein, Feed Value And Percent Lysine Of Corn Grown In The 1991 Kentucky Hybrid Corn Performance Test, C. G. Poneleit, K. O. Evans, Michael Collins, D. O. Liptrap
Agronomy Notes
These data are the results from the second year of protein analyses of corn hybrids grown at three locations in the Kentucky Hybrid Corn Performance Test. These analyses were supported. by a grant from the Kentucky Corn Growers Association.
