Tarp impacts on crop growth

These data demonstrate the impacts of tarps on crop (lettuce, Lactuca sativa) growth. We planted lettuce 1 week after tarp removal and surveyed lettuce growth 2, 3, and 4 weeks after tarp removal. We surveyed lettuce by randomly selecting 10 lettuce individuals in each plot (1 m x 2 m) and for each lettuce individual counting the number of leaves it contained and measuring the length and width of its largest leaf.

Farm: the farm site (“A,” “B” or “C”) where the plot was located. All farms were located in Chittenden County, Vermont, USA 2. Sampling: the sampling period, indicating the number of weeks after tarps were removed 3. Date: date of sampling 4. Treatment: indicates the treatment type (silage tarps, clear plastic tarps, or control) 5. Plot_Replicate: the treatment replicate number on each farm (1-6 for each treatment on each farm) 6. Plot_ID: the unique identifier for each spatial plot 7. Lettuce_Replicate: the replicate number (1-10) of lettuce individuals that were measured in each plot 8. Number_Leaves: the number of leaves on the lettuce individual 9. Length_LargestLeaf: length in mm of the largest leaf on the measured lettuce individual 10. Width_LargestLeaf: width in mm of the largest leaf on the measured lettuce individual
