|2020-2021 Mid-Atlantic Commercial Vegetable Production Recommendations||
This guide lists vegetable varieties that are available and are adapted to the mid-Atlantic region, gives an overview of cultural practices, and list chemicals recommended to manage pests, diseases and weeds in vegetable crops. New varieties of vegetables are constantly being developed throughout the world. While all efforts are made to have comprehensive lists, not all varieties that are adapted will be listed.

|Virginia Cotton Production Guide 2016||
Proper soil fertility management ensures sufficient nutrients for maximum cotton production. Obtaining and maintaining appropriate soil nutrient concentrations is imperative, as fertilizer inputs are the largest component of production budgets for Virginia cotton farmers. At the same time, excessive nutrient application wastes money, wastes natural resources, and can negatively impact yields and environmental quality.

|Southeastern U.S. 2020 Vegetable Crop Handbook||
New varieties and strains of particular varieties of vegetables are constantly being developed throughout the world. Since it is impossible to list and describe all of them, only some of the better performing commercial types are listed in the specific crop section, either alphabetically or in order of relative maturity from early to late. These varieties are believed to be suitable for commercial production under most conditions.

|Nitrogen and Sulfur Leaching Potential in Virginia||
Early summer often means locally heavy and sporadic rainfall as thunderstorms deliver intense rains, and 2015 appears to be no different with many areas in eastern Virginia receiving 3+ inches of rain in a few days (Figure 1). These storms also often coincide with the timing of sidedress nitrogen (N) and sulfur (S) applications on corn. While some rainfall after sidedress is very beneficial to facilitate N movement into soil, heavy rain (2+ inches) often leaves us wondering how much, if any, of that recently-applied N remains and if additional N is needed.

|The Nutrient Value of Straw||
The mature and dried stem, leaves, and chaff remaining after barley and wheat are harvested is known as straw. Many farmers around Virginia harvest straw by baling in small bales, large round bales, or large square bales that range in weight from 40 to 1,000 lbs. plus per bale.

|Yellow Corn in Virginia – Spring 2016||
Many of the corn fields on the Eastern Shore and in Eastern Virginia are “yellow” and stunted due to the weather this Spring (Figs. 1 and 2) and is similar to conditions that Virginia farmers experienced in Spring 2010. There are many reasons for the corn to be yellow that range from nutrient deficiencies to abiotic factors.

|Yellow Corn in Virginia – Spring 2017||
According to Meteorologist Scott Minnick with the NOAA-National Weather Service in Wakefield, VA, May 2017 is “yet another wet and cloudy May for the record books. With the rain on [May 31, 2017], Norfolk moved up to the 3rd wettest May on record.” The 2017 growing year is almost identical to last year (the wettest May on record for Norfolk, VA), with a dry March and April leading into a record breaking cool and wet May as corn tries to establish roots. Young corn largely depends on residual and starter fertilizer prior to sidedress applications and these fractions can be impacted greatly with excessive rain.

|Sensor-Based, Variable-Rate Nitrogen Applications in Virginia||
Variable-rate applications (VRA) of nitrogen (N) fertilizers are a new option to assist producers with real-time fertilizer rate decisions. Two commercially available systems that allow variable-rate nitrogen applications are GreenSeeker (Trimble Navigation Limited; www. ntechindustries.com/greenseeker-home.html) and the OptRx Crop Sensor (Ag Leader Technology; www. agleader.com/products/directcommand/optrx/). A discussion of the science behind these systems, potential economic benefits, and other methodologies to make VRA is discussed in Virginia Cooperative Extension publication 442-505, “Precision Farming Tools: Variable- Rate Application” (Grisso et al. 2011).
