Field experiments designed to reveal the effects of certain management practices and fertilizer applications on the nutritional status of highbush blueberries (Vaccinium corymbosum) were conducted during the summer of 1967. The concentration of N and Ca in the leaf tissue of plants receiving general grower care are similar to Ballinger's estimated deficiency levels while that of Mn was very high. Mn levels were higher in plants growing on the highly decomposed peats. The application of N or NPK increased the concentration of these individual elements. Increases in N appeared to depress the uptake of Mg and encourage the utilization of P. Certain management practices improved nutrient utilization especially under the high fertilizer treatment regime. A negative correlation existed between N and growth ratings in 2 of the 3 experiments. There was no indication that herbicides reduced the uptake of nutrient elements. The leaf levels of the cations Mg, Ca and Mn all declined as the yield increased. Soil temperature and moisture levels were consistently greater in hoed and herbicide treated plots than in mowed plots. / Land and Food Systems, Faculty of / Graduate

The kinetics of moisture loss and solids gain during osmotic dehydration of blueberries under different conditions of temperature (37--60°C), concentration of the sucrose solution (47--70°Brix) and contact time between fruit and sucrose solution (0.5--5.5 h) were studied, and modeled based on Fick's law of unsteady state diffusion. The rates of moisture loss and solids gain were also related to temperature and sucrose concentration. / The second stage convective drying behavior of osmo-dehydrated blueberries was evaluated in a forced air cabinet dryer (temperature: 50°C, relative humidity: 14%, air velocity: 0.6 m/s) with a cross-flow tray arrangement. Osmotic dehydration pre-treatments included different combinations of temperature, sucrose concentration and contact time. Fick's second law of unsteady state diffusion was used to model the air drying kinetics. / The quality of two-stage osmo-convective dried blueberries with respect to color, texture and rehydration ratio was evaluated. The parameters analyzed for color were the total color difference (DeltaE) and, the (a/b) ratio as the indicator for the red-blue color. The texture analysis included evaluation of the hardness, chewiness and stickiness of the osmo-convective dried blueberries. (Abstract shortened by UMI.)
