Herbicide Evaluation In Arkansas Rice, 1997, Ron Talbert, Ford Baldwin, David Gealy, Eric Webster, Tomilea Dillon, Lance Schmidt, Jeff Rutledge, Celeste Wheller, Leopoldo Estorninos Jr.

Arkansas Agricultural Experiment Station Research Series

Weed control is economically important for production of rice, a major crop in Arkansas. These findings summarize efforts of the team of Arkansas scientists working on weed control strategies for rice during 1997. Various technologies were evaluated in field studies at five locations involving the major weed problems and rice production systems used in the state. Results from these studies will add to the arsenal of weed control options for producers. Highlights include synergists and safeners for herbicides to aid in control of propanil-resistant barnyardgrass; herbicides and flooding techniques for control of red rice and other weeds; and the use …

Arkansas Soil Fertility Studies 1998, Wayne Sabbe

Arkansas Agricultural Experiment Station Research Series

Rapid technological changes in crop management and production require that the research efforts also be presented in an expeditious manner. The contributions of soil fertility and fertilizers are major production factors in all Arkansas crops. The studies contained within will allow producers to compare their practices with the university’s research efforts. Additionally, soil test data and fertilizer sales are presented to allow comparisons among years, crops, and other areas within Arkansas.

Farm Operator Satisfaction With Retail Pesticide Suppliers In The Arkansas Delta, Bruce L. Dixon, Damon Mckelvey, Travis Rogers, Frank L. Farmer, Daniel M. Settlage

AAES Research Reports and Research Bulletins

Two hundred ninety farm operators in the three easternmost crop reporting districts in Arkansas responded to a mail survey in November 1996 about their preferences and satisfaction with retail pesticide suppliers.Results show most farmers are quite satisfied with their main retail pesticide supplier, although 55.5% of the farm operators used more than one retail pesticide supplier in 1996. Users of multiple suppliers were less satisfied with their suppliers than those using only one supplier. Availability of certain pesticides was the most frequently mentioned reason for using multiple suppliers. Several attributes were important in selecting the main supplier with reputation being …

Field Evaluation Of Herbicides On Small Fruit, Vegetable, And Ornamental Crops, 1997, Ron Talbert, Lance A. Schmidt, Jennifer A. Wells, Jeff S. Rutledge, Dolores A. Parker

Arkansas Agricultural Experiment Station Research Series

Growers generally use herbicides to efficiently produce high-quality fruit and vegetables for processing or fresh market sales. Due to the smaller acreage of these crops compared to major field crops, fewer herbicides are registered for use in fruit and vegetable crops than for field crops. Each year, new herbicides are evaluated under Arkansas growing conditions with the objective of improving the herbicide technology for the grower, processor, and ultimately the consumer. This report includes studies on the control of many of the more serious weed problems in important crops of this region, including snapbeans, spinach, southern pea, watermelon, cantaloupe, tomato, …

Intsormil 1999 Annual Report, John M. Yohe, Thomas Crawford Jr., Joan Frederick, Dorothy Stoner

INTSORMIL Impacts and Bulletins

Presently, worldwide, more than 800 million people do not get enough to eat or have access to a balanced diet to be healthy. At the World Food Summit in 1996, the United States of America (USA) and 185 other countries pledged to reduce the number of malnourished people by one half by 2015. It is shocking that about 33% of preschool children in developing countries will be stunted due to malnutrition by the year 2000. The number of stunted children in Africa alone has increased significantly from 35 million in 1980 to 45 million in 1995 and is predicted to …

Aphanomyces-Resistant Alfalfa: A Solution To A Common Problem In Spring Seedings, Paul C. Vincelli, Jimmy C. Henning, Tim Hendrick, Gerald D. Brown, L. J. Osborne, Beth Prewitt, Val Shields, Don Sorrell, Kim Strohmeier, Ray Tackett, Joe Wyles

Agronomy Notes

For several decades, farmers have experienced a common stand-establishment disease syndrome when spring-seeded alfalfa was followed by extended periods of wet weather. Seedlings affected by this syndrome exhibit severe stunting as well as yellowing and reddening of seed leaves (cotyledons), but they do not wilt or collapse, as they might from a damping-off disease. Commonly, the problem affects most or all of the field.

Based on research that began in the 1980's, we suspected that a fungus called Aphanomyces euteiches (hereafter simply called Aphanomyces) was responsible. This root-rot fungus can be found in the majority of alfalfa fields we …

Nitrogen Utilization Efficiency Of Creeping Bentgrass Genotypes, Y. Kuo, David J. Wehner, T. W. Fermanian, John M. Swiader

Office of the Dean (CAFES) Scholarship

A greenhouse study was conducted in a hydroponic system to determine the nitrogen (N) utilization efficiency (NUE) of 14 creeping bentgrass cultivars. There were significant differences among cultivars in plant tissue dry weight, tissue N content, root absorption efficiency (RAE), and NUE. Considering all plant tissue (whole plant), 'Penncross' accumulated the highest N accompanied with the highest whole plant dry weight (WPDW), while 'Allure' accumulated the lowest total Nand WPDW than all the other cultivars. The proportion of WPDW and total N partitioned to shoots was higher than partitioned to roots in each cultivar. On a whole plant basis, 'Regent' …

Nitrogen Utilization In Creeping Bentgrass, Y. Kuo, T. W. Fermanian, David J. Wehner

Office of the Dean (CAFES) Scholarship

N utilization, including plant dry weight (DW) production, total N and nitrate N (NO₃-N) content accumulation, N utilization efficiency (NUE), root absorption efficiency (RAE), reduced N accumulation, and nitrate assimilation capacity (NAC) were determined for creeping bentgrass cultivars grown in hydroponic culture. Possible mechanisms affecting N utilization including nitrate reductase activity (NRA) and root morphology were also examined. Four cultivars, selected from an initial screening of creeping bentgrasses were grown under both low and high levels of N in a flowing solution culture system. The relationship between NUE and plant growth for two different creeping bentgrass cultivars was …

Field Evaluation Of Super Urea® For Production Of No-Till Corn, Kenneth L. Wells, James E. Dollarhide, H. E. Burkwhat

Agronomy Notes

Nitrification inhibitors and urease inhibitors have been commercially available to farmers for several years. Nitrification inhibitors are intended to minimize losses of nitrate nitrogen (NO₃-N) from soil due to leaching and denitrification, by slowing the activity of soil bacteria which convert ammonium nitrogen (NH₄-N) to the more easily lost NO₃-N. This has the potential to make NH₄-N or urea fertilizer sources of N more effective, particularly during late spring and early summer when soil and climatic conditions are usually more favorable for leaching or denitrification of NO₃-N. Urease inhibitors slow …

Do Cover Crop Residue And No-Till Increase Poultry Litter Runoff?, M. A. Cooprider, Mark S. Coyne

Agronomy Notes

Manure and litter produced during broiler production are an environmental issue in Kentucky. The most common and practical disposal method is to apply the poultry wastes to pasture and crop land. If the wastes are incorporated by tillage immediately after application to crop land, nitrogen that might otherwise be lost by ammonia volatilization is conserved. However, incorporating wastes is not possible in no-till, which is a best management practice (BMP) used by 51% of Kentucky's farmers to control soil erosion. One question is whether surface application of poultry wastes onto no-till fields could increase fecal bacteria contamination of surrounding waterways …
