Root-knot nematode-resistant alfalfa suppresses subsequent crop damage from the nutsedge-nematode pest complex
Southern root-knot nematode [RKN, Meloidogyne incognita (Kofoid & White) Chitwood], yellow nutsedge (YNS, Cyperus esculentus L.), and purple nutsedge (PNS, C. rotundus L.) occur together as a mutually beneficial pest complex in sandy soils. All crops grown in infested soils are affected due to the wide host range of the nematode, the perennial life cycle of the nutsedges, their interactions, ...

Corn grain yield response to crop rotation and nitrogen over 35 years
Crop rotation and N are management methods that can increase corn (Zea mays L.) grain yields. Our objective was to determine the corn grain yield response to six crop rotation sequences and four N rates in a long-term (35-yr) study. The rotations were continuous corn (CC), corn–alfalfa (Medicago sativa L.) (CA), corn–soybean [Glycine max (L.) Merr.] (CS), corn-corn-corn-alfalfa-alfalfa (CCCAA), ...

Yield, yield components, and forage nutritive value of alfalfa as affected by seeding rate under irrigated conditions
Persistence is a critical component of alfalfa (Medicago sativa L.) crop yield. Our objective was to determine the effect of seeding rate on alfalfa persistence, yield, and yield components and how they evolved over time in irrigated areas with long growing seasons. Two alfalfa cultivars were seeded at four seeding rates (10, 20, 30, and 40 kg ha–1), in three consecutive experiments, and ...

Living mulch forage yield and botanical composition in a corn-soybean-forage rotation
Managing forages as living mulches during row crop production requires suppressing the forages to produce economical crop yields. The objective of this research was to identify forage plants with varied growth habit, persistence, and yield potential to provide desirable ecosystem functions in a multifunctional cropping system. Alfalfa (Medicago sativa L.), kura clover (Trifolium ambiguum Bieb.), ...

Improving alfalfa irrigation in The west
Alfalfa grown for forage is a major crop in many areas of the western United States. In the arid and semi–arid west, irrigation is required to obtain economic alfalfa yields. Because alfalfa is a perennial crop with a potentially long growing season, it can use a substantial amount of water. Alfalfa production in Imperial County, CA, has been valued at more than $170 million dollars for ...

USGS Study Points To Biofuel Crop Related Land-Use Change Reducing Honey Bee Habitat
On August 29, 2016, the U.S. Geological Survey (USGS) published a study on the result of land-use changes on North and South Dakota commercial honey bee colonies in the journal Proceedings of the National Academy of Sciences. USGS scientists found that grasslands and other landscape features favored by beekeepers were decreasing, with crops that are avoided by beekeepers, such as corn and ...

Reuse of Dairy Lagoon Wastewater Through SDI in Forage Crops
Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of Subsurface Drip ...

Utilizing Optical Satellite Imagery to Monitor Temporal and Spatial Changes of Crop Water Stress - Alfalfa- Case Study
The study was accepted for publication in the academic journal “Water”. It suggests a new way of mapping the crop water stress on the pixel level – Optical Stress Index ...

Can drip irrigation keep the Prairie Profitable?
The use of flood and center pivot irrigation of crops via the waters of the Ogallala Aquifer is as hot a discussion topic as the current drought. To many who mine the aquifer to make a living, trying to keep a profitable way of life sustainable in a time when the broader public is seeking more conservation of resources yet wanting inexpensive, plentiful and safe food is problematic. Perhaps it's ...

Can genetic engineering help quench crops’ thirst?
Researchers around the world are exploring how GMO technology might boost food production under hot, dry conditions. Roger Deal is trying to figure out how plants remember drought. An assistant professor of biochemistry and genetics at Emory University, Deal says most plants have a kind of memory for stress. When experiencing water shortage, for example, plants close the holes in their leaves, ...

Hit the Spring Planting Target with Hydraulic Down Force
Will Hutchinson enjoys a good challenge, especially when it comes to improving production on his row crop, wheat and alfalfa farm near Murfreesboro, Tennessee. So when he saw the opportunity to leverage Ag Leader’s Hydraulic Down Force system to prevent a common problem and improve his planting operations on acres where he plants cover crops, he jumped at the chance. Two years later, ...

Rake In Greater Capacity And Higher Hay Quality
It’s been said that the steel-toothed dump rake was first introduced in the 1860s. Of course, the process back then was to rake hay into piles, which were then pitched onto a wagon for transport to a haystack or the barn loft. To make windrows for the balers that came later, the operator simply spaced the “dumps” equally so they lined up in the field. The irony is that until ...
