3. Statistical analysis
The three compost site experiments were conducted in a complete randomized design with five replications = 5 tea bags for each date of removal and burial depth. For the Sde Eliyahu compost site the standard error of the mean of seed germination for each date of removal at each burial depth was calculated.
The P. aegyptiaca incubator experiments were repeated two times for the 55 °C conditions, three times for the 50 °C conditions and once for the 48 °C conditions with five replications for each treatment. Data presented was averaged for the five replications in each experiment and the standard error of the means was calculated.
The warm water bath experiment was conducted twice with five replications per treatment in each experiment. A T-test showed no significant differences between the means of the experiments, thus the presented data was averaged for the two experiments and the standard error of the means was calculated.
