The purpose of this investigation was (1) to investigate the relationship of four potato varieties, the sucrose content at harvest, storage temperatures, and the length of storage time to the color of chips from potatoes grown in central Maine and (2) to develop an equation that will help forecast the potential chipping qualit y of potatoes grown in central Maine
Tb102: A Markov Analysis Of Structural Change And Output Prediction In The New England Egg Industry, Steven P. Skinner
Tb102: A Markov Analysis Of Structural Change And Output Prediction In The New England Egg Industry, Steven P. Skinner
Technical Bulletins
The purpose of this study is to examine changes in the size distribution of egg farms as a Markov process in the three-state region consisting of Connecticut, Massachusetts, and New Hampshire. In 1978 these three states together received cash receipts of 83 million dollars from egg sales. In addition to examining the size distribution of farms, the occurrence of a marked structural change in the egg industry during the period 1967 to 1978 is statistically tested. Also, the future size distribution of egg farms, total number of layers, and egg output are projected.

Effect Of Dusts On Tomato Production, Walter Jacob Cox, L T. Jones, Dennis R. Phillips
Technical Bulletins
The phytotoxicity of bauxite, cement flue, mud lake, alumina and kaolin dusts were examined on tomatoes. Mud lake white dust caused severe leaf scorch, affected plant growth and resulted in no harvestable yield. Flue dust applied daily depressed market yield of fruit from 64 t ha to 42 t ha. Flue dust applied at 3.1 t ha had no effect. There was no phytotoxic effect from bauxite, alumina or kaolin.

The onset of visual damage varied with the season. The symptoms consisted of marginal and tip necrosis in the early stages with the necrotic areas gradually expanding between the veins. In severe cases the leaves shed. Old leaves were affected first although foliage of any age was affected in cases of severe fluoride pollution. Plant analysis indicated that damage was associated with concentrations in excess of 20 ppm fluoride.
