Effect of ethephon and planting density on lodged plant percentage and crop yield in maize (Zea mays L.)

February 2014

Increasing maize production is vital in many developing countries. One way of increasing production is through adoption of high planting densities. However, high planting densities are associated with intra-specific competition between plants for resources like nutrients, water and sunlight, as a result weak stalks develops which are susceptible to lodging. The challenge of lodging in high planting densities can be...
