What is the irony regarding Okonkwo planting his yam seeds early versus the lazy men who planted their yam seeds late the first season?

The irony in Okonkwo planting his yam seeds early lies in his belief that hard work and diligence will ensure success, contrasting sharply with the lazy men who procrastinated and planted late. Despite Okonkwo's efforts, the late planters ultimately harvested more yams that season due to favorable weather conditions, highlighting how his adherence to traditional values did not guarantee success. This situation underscores the unpredictability of farming and the futility of overemphasizing personal effort when external factors play a significant role. In a way, it reflects the broader theme of how rigid adherence to cultural norms can lead to unforeseen consequences.
