Jennifer and Terry discussed the Lake Erie Regional Grape Program meeting's focus on crop estimation and fruit thinning in Concord vineyards, including the importance of yield-to-pruning weight ratios and accurate sampling methods. They explored various techniques for estimating crop yields and emphasized the significance of achieving balanced vineyard conditions through proper thinning practices. The conversation ended with plans for an upcoming demonstration day on July 16th at the Cornell Lake Erie Research and Extension Laboratory, where attendees will learn about crop estimation and fruit thinning techniques for sustainable grape production.

Fertilizer Calculators for Concord Vineyards (Beta)

by Dr. Terry Bates.

Dr. Terry Bates emphasizes that the new Nitrogen and Potassium Fertilizer Calculator for Concord Vineyards (Beta) represents a significant step forward in managing vineyard nutrition. By integrating scientific research with practical applications, Dr. Terry Bates and the team are equipping growers with the tools needed to optimize their vineyard practices. For those interested in leveraging this calculator, visit the Efficient Vineyard website and navigate to the viticulture blog. We encourage you to explore this tool and reach out with any questions or feedback.

Dr. Terry Bates emphasizes that accurate crop estimation provides valuable information, allowing growers to decide whether thinning is necessary. Thinning is often debated among growers, but knowing the crop load can significantly influence management decisions. To simplify the estimation process, a crop estimation calculator has been developed. This tool allows growers to input row spacing, vine spacing, days after bloom, how many vines or length of row sampled, weight of fruit in sample, and estimated vine size for the sample. With the information that you input, it calculates the harvest yield prediction. It also factors in pruning weight to calculate the revised index, helping growers understand whether their crop load is balanced or overcropped, and then gives a Thinning Consideration in tons/acre (See Figure 1 below). The calculator aids in making informed decisions about thinning and ultimately helps maintain vine health and productivity.

Between the Vines hosts Dr. Katie Gold from Cornell University to learn more about her work with fundamental and applied science of plant disease, work with NASA, and Mancozeb updates.

Dr. Kaitlin (Katie) Gold is an Assistant Professor of Grape Pathology in the Plant Pathology and Plant-Microbe Biology Section of the School of Integrative Plant Science at Cornell University where she holds primary research and extension responsibilities for grape disease management in New York State.

Dr. Gold’s Grape Sensing, Pathology, and Extension Lab at Cornell (GrapeSPEC) studies the fundamental and applied science of plant disease and plant-microbe interaction sensing to improve integrated grape disease management. The Gold Lab specializes in the use of in situ and imaging spectroscopy (also known as hyperspectral imaging) deployed at a range of spatial scales, from proximal, autonomous rovers to spacecraft, to characterize asymptomatic disease physiology and the impacts of management intervention on early grape disease detection.
