In order to verify the farmers perception towards resilience of tuber crop especially cassava whether statistically Chi-Square test has been applied. The results are presented in the Table 5
Ho: The research is unbiased, the climate change related catastrophes affects tuber crops especially cassava production (null hypothesis)
H1: The research is biased, the climate change related catastrophes not affects tuber crops especially cassava production (Alternative hypothesis)
