02-2022 Bryant Fertility and Agronomic Resource Management for Soybean Annual Report
Near record high fertilizer prices has placed increased strain on already small profit margins. For this reason, up to date non-biased research data is necessary to ensure that all soil fertility management decisions are creating not only maximum yield but profitability as well. An example of this would be ensuring the any yield increases associated with micronutrient applications are similarly increasing net returns. Many growers in Mississippi also face K deficiency on a regular basis. As K is mobile in plant tissue and early detection is critical, we must ensure that tissue samples are being collected from the correct location in the plant canopy. Due to relatively flat landscape of the Delta region of Mississippi, flooding is a problem that many soybean growers must deal with on a fairly regular basis. After flooding events growers are looking for ways to accelerate soybean recovery. With this, many growers will make a foliar application of N with the belief that it supplements what has been lost from root inactivity and hastens recovery time. It is also crucial that research personnel continually collect production field level data to stay abreast of ever-changing soil conditions and be able to proactively prepare for possible issues. Specific objectives are 1) Data collection; 2) Establishing optimum tissue sampling location within a plant canopy for early deficiency detection of plant-mobile nutrient potassium; 3) Establishing optimum boron fertilizer application rates and timings for soybean grown on soils ranging from clay to sandy loam; 4) Determine the effect of foliar N applications on soybeans subjected to flooding during the late vegetative to early reproductive growth stages; and 5) Provide first-hand learning opportunities for existing and new soil fertility programs.
Morpho Physiological, Yield, and Transgenerational Seed Germination Response of Soybeans to Temperature
Temperature is the primary factor affecting the morpho-physiological, developmental, and yield attributes of soybean. Despite several temperature and soybean studies, functional relationships between temperature and soybean physiology and yield components are limited. An experiment was conducted to determine the optimum temperature for soybean gas exchange and yield components using indeterminate (Asgrow AG5332, AG) and determinate (Progeny P5333 RY, PR) growth habit cultivars. Plants grown outdoors were exposed to 5 day/night temperature treatments, 21/13, 25/17, 29/21, 33/25, and 37C/29C, from flowering to maturity using the sunlit plant growth chambers.
01-2022 Cook Management of Insect Pest in Mississippi
Experiments were conducted to evaluate the performance of selected insecticides against a range of soybean insect pests including, seedling/soil insects (corn rootworm, wireworm, pea leaf weevil), bean leaf beetle, soybean looper, and stink bugs (including redbanded stink bug).

36-2022 Irby SMART Program Annual Report
This SMART Program annual report was conducted by Dr. Trent Irby and funded through the Mississippi Soybean Promotion Board. This MSPB supported research, on-farm soybean variety demonstrations is conducted throughout Mississippi.
23-2022 MAFES 2022 Soybean Variety Trials Seed Quality Ratings, Annual Report
Three of Mississippi Agricultural and Forestry Experiment Station (MAFES) Variety Testing Program locations (Crystal Springs and Verona non-irrigated and Stoneville loam soil irrigated) were rated for quality by Midsouth Grain Inspection Services, an official USDA-designated grain inspection agency. Ratings represent damage from each location and labeled “Damaged Kernels Total” and expressed in percentage of that sample size with damage kernels. Plots were harvested as quickly as possible so these ratings in the tables do not express any extended weathering pattern.
