SUMMARY Sensing of maturity in blueberries (Vaccinium darrowi L.) using optical density measurements has long been known and used by researchers. This past year a large sample of berries (540) were visually selected with six levels of maturity; Green

Many types of produce require thorough cooling immediately after harvest to minimize quality losses. In many instances, this is accomplished by forced-air cooling in a refrigerated room. This study was conducted to determine the applicability of resi

Ahigh-pressure high-volume sprayer with provision for recapturing and recycling undeposited spray was mounted on a high-clearance tractor and used to apply wetting sprays to blueberry bushes for blueberry bud mite (Acalitus vaccinii, Keifer) control.

IMPACT and compression rheological models, derived from continuum mechanics, were developed to predict the force response of an impacting and a slowly compressed blueberry, respectively. A relaxation modulus was used in the models. An equation to cal

CONSIDERABLE interest is being shown by both horticulturists and growers in the mechanical har-vesting of dwarf and semi-dwarf trees, especially apple trees grown in hedgrow and high-density orchards. However, the harvesters and other orchard equipme

A nonlinear differential equation was used to model the contact force of the rebounding blueberry. Model parameters were determined by a least squares curve fitting algorithm resulting in correlations of 0.98 for model mass with berry mass and 0.62 f
