**Table 3:** Results of two sample T-tests, where the cucumbers height mean values of aquaponics were compared to those of soil system and the differences were statistically evaluated for p < 0.05, after the two sample test for variance was performed by using OriginPro 2016 (OriginLab, Northhampton, MA).

Time | Traditional system mean | Traditional system standard deviation | Aquaponic system mean | Aquaponic system standard deviation | Prob > |t| |
Two sample test for variance | Prob > F |
---|---|---|---|---|---|---|---|

Day 0 | 7.5 | 1.58 | 3.6 | 0.97 | 3.03E-06 | Equal variances | 0.16 |

Day 4 | 8.5 | 1.65 | 5.3 | 1.25 | 1.19E-04 | Equal variances | 0.42 |

Day 11 | 15.7 | 1.83 | 10 | 1.76 | 1.30E-06 | Equal variances | 0.92 |

Day 18 | 24.5 | 5.28 | 21.4 | 3.81 | 0.15 | Equal variances | 0.34 |

Day 25 | 41.8 | 9.73 | 38.2 | 5.25 | 0.32 | Equal variances | 0.08 |

Day 32 | 60 | 14.79 | 48.6 | 6.48 | 0.04 | Different variances | 0.02 |

Day 39 | 79 | 19.63 | 51.1 | 5.72 | 1.36E-03 | Different variances | 1.11E-03 |

Prob > *|t|* and Prob > F indicate if the p-value was less than 0.05 in the two sample t-tests and two sample tests for variance, respectively.
