Summary: The objectives of this project were: 1. Develop a portable (OSU) meter for determining chlorophyll and nitrogen in fresh leaves of apples and other fruit trees. 2. Test and compare the accuracy of the OSU prototype with the commercial meters. 3. Develop a second OSU prototype with better accuracy by eliminating factors that interfered with the wavelengths used to measure chlorophyll and nitrogen. 4. Develop a software for converting the meter readings from all the meters tested into chlorophyll and nitrogen content. 5. Develop the database for most important species and cultivars including apple, pear and cherry
