He is not. He grows yams in Mbanta instead.
Okonkwo previously had yams stored in Umuofia, which were transferred to Obierika's barn. These were then sold by Obierika, with the proceeds given to Okonkwo.
Okonkwo originally lives his life in Umuofia, but he is exiled for seven years. During this time, he lives in his motherland, Mbanta. He eventually returns to Umuofia.
Later on, after Okonkwo is exiled, Okonkwo plans to have Ezinma and Obiageli marry men in Umuofia, so that they will still be in the village, and Okonkwo and his family will have additional influence in the village. Thus Ezinma and Obiageli refuse every offer of marriage from men in Mbanta.

Mbanta is less war like. Umuofia is a proud tribe with many strong fighters. Mbanta is much more moderate, and especially respectful of the earth mother.Umuofia and Mbanta represent the fatherland and the motherland respectively to Okonkwo. Umuofia is a place where he places his ambitions and dreams, and Mbanta is where he runs to when things go disasterously wrong.
Okonkwo does not ask Ezinma to not marry, but rather to not marry anyone in his motherland of Mbanta, as then she would become part of that village. Okonkwo would rather have her marry a titled man in Umuofia, to increase their family's influence and togetherness in Umuofia.

Okonkwo is discouraged by the fact that he has to come to Mbanta in the first place. He is discouraged that he is unable to take part in his village's high society, and that he has lost so much. His great passion was to be one of the lords of his clan, but that avenue was now blocked to him.

Okonkwo is at first depressed. His plans have gone astray. His hard work seems to have been for naught. His farms and property have been destroyed, and he must wait seven years before he can ascend the ranks in his village again.
