Figures & data
Figure 1. Volumetric water content of a representative 8-day period of pot watered with 100% of open pan evaporation as measured by a theta-probe in the top 5.7 cm of the root zone under daily, 2-, 4-, and 7-day irrigation frequencies. Arrows represent watering events in each respective treatment. Each point represents a single measurement with one measurement per pot per day.
Figure 2. Counts of moss leaflets in a 7.5-cm diameter pot of creeping bentgrass under daily, 2-, 4-, and 7-day irrigation frequencies in the first of two experiments. Each bar represents an average of four replicates at two different irrigation rates 100% and 75% of open pan evaporation for a total of n=8. Bars with different letter are significantly different at alpha=0.05.
Figure 3. Fresh weight of moss leaflets in a 7.5-cm diameter pot of creeping bentgrass under daily, 2-, 4-, and 7-day irrigation frequencies in the second of two experiments. Each bar represents an average of four replicates at two different irrigation rates 100% and 75% of open pan evaporation for a total of n=8. Bars with different letter are significantly different at alpha=0.05.
Figure 4. Dry root mass below 12 cm of depth in a 7.5-cm diameter pot of creeping bentgrass under daily, 2-, 4-, and 7-day irrigation frequencies in the first of two experiments. Each bar represents an average of four replicates at two different irrigation rates 100% and 75% of open pan evaporation for a total of n=8. Bars with different letter are significantly different at alpha=0.05.
Figure 5. Total dry root mass in a 7.5-cm diameter pot of creeping bentgrass under daily, 2-, 4-, and 7-day irrigation frequencies in the second of two experiments. Each bar represents an average of four replicates at two different irrigation rates 100% and 75% of open pan evaporation for a total of n=8. Bars with different letter are significantly different at alpha=0.05.
