Tarp impacts on crop yields

These data demonstrate the impact of tarps on crop yields (for lettuce, <em>Lactuca sativa</em>). We planted lettuce 1 week after tarp removal and harvested lettuce after 4 weeks of growth. At the time of harvest, we counted the number of lettuce individuals that grew within each plot (1 m x 2 m). We then harvested the lettuce and (after washing and drying it) measured the total weight (crop yield) of all lettuce individuals in each plot.

Farm: the farm site (“A,” “B” or “C”) where the plot was located. All farms were located in Chittenden County, Vermont, USA 2. Treatment: indicates the treatment type (silage tarps, clear plastic tarps, or control) 3. Plot_Replicate: the treatment replicate number on each farm (1-6 for each treatment on each farm) 4. Plot_ID: the unique identifier for each spatial plot 5. Number_lettuce: number of lettuce individuals in each plot 6. Total_Crop_Weight: weight in grams of all lettuce plants (cleaned and dried) within the plot boundaries. This weight is used to indicate crop yields.
