SUGAR BEET MELD AND SUGAR CONTENT On October 3, several days prior to the commercial harvest of the beets, two rows, 3m long from each of the three replicate treatment, were topped, then dug by hand, weighed and sent to the Michigan Sugar Company for sugar laboratory analysis, (Fig. 11 a, b).

EVAPOTRANSPIRATION VALUES A comparison of calculated and measured reference evapotranspiration was made. A calculated reference evapotranspiration (ETo) was determined at each of the two research test sites, Location A and B using the standard meteorological weather information from the three closest MAWN (Michigan Automated Weather Network) sites at Fairgrove, Munger and Saginaw, (Fig. 1). The formulae used to calculate ETo was from the Priestly- Taylor model. These daily calculated ETo values were compared to the measured values using an Atmometer sensor located at the test sites. An Atmometer is an instrument with a porous membrane connected to a reservoir of water by a wicking mechanism that allows water to difhse to the atmosphere. By monitoring the volume of water lost, the user can obtain a measure of the evapotranspiration. Fig. 12 Atmometer to measure reference evapotranspiration @To). Photograph from Manufacture's web.
