Estimating First Crop Alfalfa Harvest using PEAQ
Alfalfa growth and development is affected by many factors, including temperature, soil moisture, stand age and even cultivar. Alfalfa growth has been slow this spring due to cooler than normal weather. This is a reminder that using the calendar date to determine when to harvest the first crop of alfalfa may not be the best method. In order to accurately predict the optimal time for the first cutting, the University of Wisconsin developed the Predictive Equations for Alfalfa Quality (PEAQ) method.

The Current Cucurbit
The main focus of our three-state (Iowa, Kentucky, and New York), three-year (2020-2022) project is on finding better ways to manage diseases, insect pests, and weeds in organic systems, and getting that information to growers. Our funding comes from USDA’s Organic Research and Extension Initiative (OREI).

Welcome to SmarterAppleSpraying!
The Intelligent Sprayer is the creation of a team of USDA-ARS engineers at Wooster, Ohio, led by Dr. Heping Zhu. It has been tested on nursery trees, peaches, grapes, and other large-canopy crops, and is now available commercially for retrofitting standard airblast sprayers. Our study is the first to evaluate the Intelligent Sprayer for control of the full range of pests and diseases on apples during the whole growing season.
