Full-Season and Double-Crop Soybean Response to Potassium Fertilizer
… for potassium (K) increases with increasing soybean yield. Little research has been conducted on soybean response to K on coastal plain and piedmont soils of Virginia, especially in double-crop systems. Nineteen full-season and 14 double-crop soybean experiments were conducted in 2013 and …

Double-Crop Soybean Vegetative Growth, Seed Yield, and Yield Component Response to Agronomic Inputs in the Mid-Atlantic, USA
… and profitability are the primary reasons for double-cropping soybean with small grain in the Mid-Atlantic, USA. Reduced double-crop yield can be attributed to: delayed planting that results in a shortened growing season and less vegetative growth; later-maturing cultivars that terminate main …

Determination and Manipulation of Leaf Area Index to Facilitate Site-Specific Management of Double-Crop Soybean in the Mid-Atlantic, U.S.A.
Double cropping soybean after small grain harvest does not always allow sufficient canopy growth to maximize photosynthesis and seed yield. This is due to a shorter growing season and moisture deficits common to the Mid-Atlantic USA. Leaf area index (LAI) is the ratio of unit leaf area of a crop to …

Assessment of Soybean Leaf Area for Redefining Management Strategies for Leaf-Feeding Insects
… must be validated for the meters. Full-season soybean require LAI values of at least 3.5 to 4.0 by early to mid-reproductive developmental stages to achieve maximum yield potential, but the relationship between double-crop soybean LAI and yield is unknown. This research (1) evaluated minimum …

Influence of Several Herbicides on Visual Injury, Leaf Area Index, and Yield of Glyphosate-Tolerant Soybean <I>(Glycine max)</I>
… other than glyphosate on glyphosate-tolerant soybean. Field studies were conducted in 1999 and 2000 to investigate potential crop injury from several herbicides on glyphosate-tolerant soybean, and to determine the relationship between soybean maturity, planting date, and herbicide treatment on …

Soybean Growth and Yield Response to Seeding Rate in Virginia
Soybean [Glycine max (L.) Merr.] seed cost has increased dramatically with the introduction and adoption of herbicide-resistant cultivars, generating interest from growers to reduce seeding rates to the lowest possible level that does not affect yield. Research indicates that greater seeding rates …

Double-Cropped Soybean Response to Various Wheat Stubble Managements
… aestivum L.) stubble management preceding double-crop soybean [Glycine max (L.) Merr.] have been reported; however, little work has been done in the Mid-Atlantic region of the United States. The objectives of this study were to observe the effects of wheat stubble management (WSM) on …

Relay- and double-crop production systems for wheat
Cover crops are important to provide organic matter to soils, diversify cropping systems, and provide economic benefits if the correct cropping systems are utilized. Relay-intercrop production involves overlapping growth cycles of two or more crops. This production system is common with legumes …

Exploring the potential of chaff lining in Virginia wheat and soybean production
… a narrow line. Since chaff amount increases with crop yield, studies aimed to determine how varying crop yield and the associated chaff amount will affect chaff lining control of select weed species, while also examining subsequent crop performance. Objective 1 of this work focused on wheat chaff …

Behavior of and Crop Injury Induced by Native and Exotic Stink Bugs in Mid-Atlantic Soybean
… if the current thresholds for stink bugs in soybean (one bug per 0.3 row m) need to be adjusted based on current soybean production practices and species present. Several soybean development stages were infested by two native stink bug species for three weeks using small cages in a field of …

Assessing the impact of cover crops on soil health in a long-term no-till rotation: a case study from Northeast Kansas
… and soil acidification over time. Cover crops have emerged as a promising tool for enhancing soil health, however, long-term effects of cover crops on soil proprieties under no-till management and various intensification schemes remain to be fully understood. This study aimed to assess …
