Over an 80-year period, marketable ear mass in sweet corn hybrids grown at high densities increased by 2.85 tons per acre, while fresh kernel mass and recovery showed minimal changes. Modern hybrids were found to be more suitable for growth at high densities due to their compact plant architecture.
University of Illinois researchers discovered waterhemp's unique mechanism to detoxify the herbicide SA3, adding complexity to controlling this weed. This finding raises concerns about the potential for waterhemp to resist new herbicides before they are even commercialized.
Researchers found that no-till production farmers can reduce herbicide use by implementing integrated weed-management practices, such as high-residue cultivation and seeding companion crops. Despite increased weed pressure, crop yields and profits were not significantly affected.
Research suggests climate change will increase disease pressure in some regions and reduce it in others. Model projections indicate that rising temperatures will boost yields in temperate areas while having little effect on tropical regions.
A team of researchers has identified key characteristics related to popcorn expansion, enabling more efficient selection and breeding of high-quality popcorn. The study found that kernel outer layer thickness is a critical trait for increased popping expansion.
A new approach to teaching agriculture in the classroom uses case studies to motivate students and inspire changes in attitude. The study found that engaging students with real-world examples improved their understanding and presentation skills, but some felt that more time was needed for discussions and activities.
Researchers transformed an agricultural science course for Kú teachers to incorporate culturally relevant learning, improving teacher confidence and student satisfaction. The course built a community of practice among teachers, incorporating project-based learning and Hawaiian culture.
A renowned science educator, Marvin Druger, reflects on his mission to inspire students to enjoy the adventure of learning. His new book, Practical Perspectives on Science Education, offers practical tips, personal reflections, and a passion for making science education meaningful and motivational.
The traditional method of discovering herbicides involves random searching of chemicals, resulting in most commercial products. New biotech information allows companies to create targeted weed killers. The American Society of Agronomy developed an interactive web lesson to teach students about the history and development of herbicides.
A study found that profitability in transgenic cotton was most closely associated with yields, rather than the technologies themselves. The research compared production systems using different transgenic technologies and non-transgenic cultivars, concluding that higher returns were achieved from non-transgenic options.
