Abstract
A large portion of irrigated soybean in Mississippi are planted on raised beds spaced 96.52 cm apart. There is recent interest in growing soybean in narrower rows. Previous research indicates that narrower row spacing can provide advantages over wider arrangements, including increased light interception, improved weed management and greater seed yield. Soybean was planted in 96.52 cm single rows, 96.52 cm twin rows and 50 cm rows on wide beds (200 cm) at three seeding rates. Canopy closure was monitored throughout the growing season. Soybean planted in narrow rows had consistently faster canopy closure than single rows at all site years. Similarly, there was a 10% to 13% seed yield advantage for the narrow row spacing over the single row spacing at each site year. With the introduction of novel technology, such as the twin row planter, comes equipment malfunction and/or misuse that could reduce seed yield. Producer decisions in the event of a planting/planter error can be challenging. The economic loss due to a planter error may vary by soil type due to differences in plant development. The purpose of this research is to determine the agronomic effects associated with multiple potential twin row planter errors on two distinct soil types across multiple maturity groups commonly found in Mississippi. Canopy closure of each planting error was monitored throughout the growing season. Seed yield was reduced by 9 to 18% when a whole twin row was missing compared to the untreated check at all site years.
