RESEARCH PLOT LENGTHS FOR SPINDLE HARVESTED COTTON Academic Article

abstract

• Agricultural scientists who conduct field experimentation are confronted with variability in soil type, soil compaction, and nonuniform insect and disease distribution. One way to reduce variability is to use the appropriate size plots. Plots of cotton, Gossypium hirsutum L., having four rows spaced 1.02 m and harvested plot lengths of 3.04 to 32.22 m with four replications were established at Marianna, Calloway silt loam (fine-silty mixed thermic Alfisols) and Clarkdale, Dubbs silt loam (fine-silty mixed thermic Alfisols), Arkansas in 1978 and 1979 to determine the effects of row length and end borders on experimental variability. Results suggest that cotton research plots harvested with a spindle picker should not be less than 12.16 m in length. End border effects were additive but different for different plot lengths, locations, and growing season. 1994, Taylor & Francis Group, LLC. All rights reserved.
