According to Chika, the priestess of Agbala, why does Unoka always have a miserable harvest?

According to Chika, he always had a miserable harvest because he expected the gods to provide everything, while he himself was weak and lazy..... thus, her answer was that he needed to go out and work like a man.

"You have offended neither the gods nor your fathers. And when a man is at peace with his gods and his ancestors, his harvest will be good or bad according to the strength of his arm. You, Unoka, are known in all the clan for the weakness of your machete and your hoe. When your neighbours go out with their axe to cut down virgin forests, you sow your yams on exhausted farms that take no labour to clear. They cross seven rivers to make their farms,- you stay at home and offer sacrifices to a reluctant soil. Go home and work like a man."
