101 POSTER SESSION 3C (Abstr. 165–172) Extension Education
A microcomputer program has been developed to keep records on energy, labor costs, product pricing, and revenue predictions for greenhouse and nursery production. The program manages plant production data, potentially enabling the grower to improve production and profits. The grower can use the program to determine how much it costs to produce individual plants, to ascertain labor costs and where to reallocate employees. Advertising and other indirect costs can be included to determine cost of production on a per-plant or per-square-foot basis.
Abstract
A 2-factor split-block experiment was initiated to test the effect of terbacil and nitrogen on yield of 6 commercial lowbush blueberry (Vaccinium angustifolium Ait.) fields in Maine. Locations served as blocks in the design. Large differences in yield were obtained among locations. An increase in yield was obtained by increasing the rate of terbacil. No significant trends due to N or the terbacil by N interactions were detected. The split-block was highly effective for grower education concurrent to obtaining replicated inform ation for generalized state-w ide recom m endations. Chemical name used: 5-chloro-3-(1,1-dimethylethyl)-6-methyl-2,4(1H,3H)-pyrimidinedione (terbacil).

Abstract
The pH of a plant growing medium is a major determinant of nutrient availability and plant growth (1), so monitoring the pH of growing media is an important management practice. The pH of growing media can be measured colorimetrically with test papers or indicator solutions (2, 4) or potentiometrically with a glass electrode pH meter (1, 2, 6). Colorblind people, estimated to be 10% of the male population, cannot use colorimetric methods (3).
