Determining an Economical Approach to Mid-South Soybean Production.

Data was conducted in 2017 and 2018 at Stoneville, MS to determine if single-row or twin-row configuration on 102 cm rows would increase soybean (Glycine max L.) grain yield while reducing seeding population; while also determining beneficial management techniques. Our primary objective was to determine if seeding rates could be reduced from the current Mississippi State University recommendation; and determine if row configuration could increase grain yield on wide rows. All trials were conducted under irrigated condition with weed and disease monitored to Mississippi State University standard. After one year of data results showed no differences among row orientation. Planting population ranged between 104,000 and 156,000 seeds per acre. Plant height was significantly taller using greater planting populations. Seed weight was significantly decreased when using the twin-row planting configuration. Neither planting population nor row configuration had a significant interaction on change in initial stand count. Canopy closure was recorded throughout the reproductive growth stages, using Canopeo phone application. Row orientation showed no differences in yield neither did planting population; reducing the seeding rate had economically benefits. All management strategies increased grain yield however the increased cost associated with these practices did not always increase net income. The use of a fungicide at R4 timing was the only management strategy that paid for the cost of product and application cost during the 2017 and 2018 growing season. The importance of this data proves that seeding rates can be reduced and still maintain grain yields although a row orientation did not provide a yield boost both have beneficial characteristics. Management decision are crucial throughout the growing season; however additional fertilization and the use of a desiccant returned no economic benefit.
