2024/2025 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.

Aerial multispectral imagery for high-throughput mapping of spatial corn yield potentials.
Drone-based spectral imaging is a nondestructive approach for estimating corn grain yield efficiently prior to harvest. Such spatial estimations if done early in the season could help growers to identify lower performing areas of the field. This will guide them to adopt prompt, precise and cost-effective crop management operations (e.g., irrigation, fertilizer or fungicide applications) in the same season or before/during next cropping season. Pre-harvest yield estimates would help in better planning and allocation of harvest, storage, and sales resources for higher profitability and crop value. This article summarizes a recent exploration on drone-based multispectral imagery to estimate grain yield potential of corn.

2023 Virginia On-Farm Soybean Research
These demonstration and research results are a collaborative effort of Virginia Cooperative Extension (VCE) Agents and Specialists, Virginia producers, and agribusiness. The purpose of this publication is to provide research-based information to aid in the decision-making process for soybean producers in Virginia. It provides an unbiased evaluation of varieties, management practices, and new technologies through on-farm replicated research using producer equipment and time. These experiments enable producers to make better management decisions based on research and provide greater opportunities to improve yields and profits, which improves quality of life for them and their families.
