The researchers analyzed how planting maize at different times affected its yield over six years in a specific region. They found that when maize was planted early (April 10), it grew more evenly as the soil was still moist, leading to higher yields. In contrast, planting at the optimal date (April 24) or late (May 10) resulted in seeds being sown into drier soil, affecting their early growth and reducing overall yield. Planting at the best time (April 24) usually produced reliable yields, but in one year (2012), planting earlier (April 10) was better because the soil was still wet, helping maize shoot up more evenly. So, when planting maize, the timing can significantly impact its yield, with earlier planting sometimes giving better results.
