Researchers studied how planting time and plant density affect maize growth and yield. The study took place in different years with contrasting weather conditions – a dry year in 2003 and a rainy year in 2004. In 2003, maize planted later had higher yields for early-maturing hybrids, while those planted earlier were better for long-maturing hybrids. Seed moisture content was influenced by planting time. In 2004, all hybrids grew best when planted at specific times. Planting density experiments showed that different maize hybrids reacted to varying plant densities over two years (45,000 to 90,000 stocks per hectare). Weather conditions, especially precipitation levels, played a significant role in determining yield. In summary, planting time and plant density can impact maize growth and production, with weather conditions being crucial for a successful harvest.
