W077 Planting Corn For Grain In Tennessee, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Although seed genetics can dictate yield, a poorly planted seed never reaches its yield potential. Favorable weather plays an important role in stand quality, but producers can save money on replant costs by managing factors that can be controlled, such as field selection and planting time, seedbed preparation, seeding rate, planter settings and insect management.

Diagnosing Crop And Pasture Problems With Detective Doug, Doug Sawkins

Bulletins 4000 -

There are numerous publications for diagnosing crop and pasture growth problems. Although they are excellent for experienced people, they can be time consuming and possibly misleading for the less experienced.

Many guidebooks assume that the user has already decided that their problem falls into the category covered by their particular guidebook, for example, a disease, pest or herbicide problem.

Guidebooks are often based on plant symptoms. However, in the field, symptoms vary and different problems can have similar symptoms.

This bulletin presents a problem diagnosis method that uses plant symptoms and paddock clues. It can be used to draw up …

Tree Windbreaks In The Wheatbelt, Robert Sudmeyer, David Bicknell, Neil Coles

Bulletins 4000 -

Windbreaks comprising trees, or tree and shrub combinations, can offer many benefits on wheatbelt farms, particularly for protection of soil, stock, crops and pastures from damaging winds and erosion. Additional benefits include reduced evaporation from farm dams, reduced groundwater recharge, their use as nature conservation corridors and habitats, increased biodiversity including predators of crop and pasture pests, fire control, tree products and improved lifestyle and aesthetics.

In other areas and farming systems such as intensive horticulture, man-made windbreaks may be used, but their higher cost makes them unsuited for broadscale agriculture. Man-made windbreaks can be effective in reducing evaporative losses …

W164 Replanting Corn - In A Failed Roundup™ Ready Corn Stand, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

In spring 2007, a widespread freeze occurred that led to the replanting of about 200,000 acres of corn in Tennessee. In most years, replant decisions have to be made on a limited number of acres when corn fields have insufficient stands for optimum yields. Producers are then forced to make a number of decisions quickly, because planting delays, particularly into mid-May, can greatly affect yield potential of the replanted crop.

W127 Common Beneficial Arthropods Found In Field Crops, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

There are hundreds of species of insects and spiders that attack arthropod pests found in cotton, corn, soybean and other field crops. A few common and representative examples are presented herein. With few exceptions, these beneficial arthropods are native and common in the southern United States. The cumulative value of insect predators and parasitoids should not be underestimated, and this publication does not address important diseases that also attack insect and mite pests. Without biological control, many pest populations would routinely reach epidemic levels in field crops. Insecticide applications typically reduce populations of beneficial insects, often resulting in secondary pest …

W129 Bt Cotton, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Bt cotton has been genetically modified by the insertion of one or more genes from a common soil bacterium, Bacillus thuringiensis. These genes encode for the production of insecticidal proteins, and thus, genetically transformed plants produce one or more toxins as they grow. The genes that have been inserted into cotton produce toxins that are limited in activity almost exclusively to caterpillar pests (Lepidoptera). However, other strains of Bacillus thuringiensis have genes that encode for toxins with insecticidal activity on some beetles (Coleoptera) and flies (Diptera). Some of these genes are being used to control pests in other crops, …

Current Property Size Distribution Of Landholders In The Northam Advisory District, Jeff Russell

Bulletins 4000 -

The reason for conducting this short study was to gain a better understanding of the property size distribution of landholdings that exists within the Northam Advisory District (NAD). There has been some deal of conjecture as to the extent of property size within the district upon which some basic assumptions are being made for the viability of farming / agricultural industries in the district.

This outline may help to give a greater accuracy of the nature of the clientele of the district in decision making processes for district extension management and on ground activities.

Sp645-When Are Micronutrients Needed For Farm Fields, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

This factsheet provides a listing of secondary and micronutrient soil tests available through the University of Tennessee Soil Testing Laboratory in Nashville. It also summarizes all of the university’s secondary and micronutrient recommendations and guidelines based on current research. Some recommendations are based upon soil test values (Table 1) interpreted as either satisfactory (levels adequate for excellent crop production) or unsatisfactory (levels indicating a need for fertilization). For other micronutrients, such as boron or molybdenum, a general recommendation is made for those crops observed to respond consistently to such fertilization. For copper, the soil test is currently only used to …

Pb1096 Liming Acid Soils In Tennessee, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Soil test results indicate that approximately 50 percent of the cropland in Tennessee is too acid for optimum crop production. Because of this, determining the need for lime should be the first step in developing a sound crop fertilization program. Lime neutralizes excess soil acids and increases pH. If not limed as needed, soils continue to become more acid, reducing the soil’s potential to produce healthy plants and profitable yields.

Measurement Of Water Stress: Comparison Of Reflectance At 970 And 1450 Nm, Daniel Dallon

Water Stress

Nitrogen stress in crops has been measured for many years using inexpensive spectrometers with ranges up to 1000 nm. Detectors for spectral measurements above 1000 nm are expensive, but they can be used to analyze water stress in plants by measuring reflectance of the major water bands at 1450 nm and 1900 nm. Although there is a water band at 970 nm, it is generally considered to be too small and inconsistent to use as an indicator of water stress. This experiment aims to determine the correlation between reflectance at 970 nm and 1450 nm. This was done by taking …

Sp597 Flooding Harvested Crop Fields In Winter: Effects On Crop Production And Opportunities For Waterfowl Management, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Flooding crop fields in winter to attract waterfowl and other wildlife is a management tool that has been used for several years. Ducks and geese are attracted to waste grain and weed seeds, while shorebirds, wading birds and mammals visit flooded fields in search of fish and/or invertebrates. Landowners are interested in this management practice because flooding fields in winter provides a place to hunt (or lease) and is visually pleasing with a variety of wildlife species using the property. In addition, there is evidence that flooding crop fields is actually cost-effective for the producer by providing increased weed control …

Fertigation Of Vegetables In Western Australia, J Burt

Bulletins 4000 -

Fertigation is the technique of using soluble fertilisers to supply essential nutrients to vegetables through sprinkler or trickle irrigation systems, or by means of a boom spray. It is ideally suited to most horticultural areas in Western Australia, especially the sandy soils of the Swan Coastal Plain that have a poor capacity to retain nutrients.

Before and after planting, nutrients are often applied to vegetables on soils of the Swan Coastal Plain by applications of poultry manure* or solid fertilisers. After planting, fertigation is a safe and effective method of applying top-dressings of nutrients to crops, especially after the rows …
