Excerpt from Influence of Field-Applied Chemical Additive on Dust Levels in CottonTwelve lots of seed cotton were harvested at random from locations in the field. Two lots were harvested without oil. For the remaining 10 lots, the intent was to vary the oil content as uniformly as possible from to percent. The design was chosen to allow regression analysis for two important reasons. First, the main objective of the test was to determine the effect of additive level on the quality measure. Although 3 or 4 points (as would be available from a randomized block design of the same total number of lots) can define a regression coefficient (bl the confidence is improved with 12 points. Second, preliminary trials indicated that the amount of oil in a lot would vary more than arbitrary treatment boundaries. This can be partially explained by the relatively small difference in ratios desired and unavoidable errors in estimating harvest rate and oil trans fer rate within the air delivery system.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
