Wheat Grain Yield Response to Seed Cleaning and Seed Treatment as Affected by Seeding Rate During the 2019–2020 Growing Season in Kansas

The objective of this project was to evaluate winter wheat stand count and grain yield responses seeding rate its interaction with seed cleaning treatment in Kansas during the 2019–2020 growing season. Experiments evaluating response variety ‘SY Monument’ three rates (600,000, 900,000, 1,200,000 seeds per acre), intensities (none, air screen, gravity table), two treatments insecticide + fungicide) were established a split-split plot design conducted complete factorial experiment ten locations. In-season measurements included yield. Despite few location-specific results, general trends uniform enough be generalized across average plant population ranged from ~285,000 620,000 plants acre, low populations occurring either sites where severe freeze damage caused winterkill or sowing followed by extremely dry periods. Grain 25 75 bushels acre. Across locations, both increased increases rate, improvements cleaning, presence fungicide plus This research is an initial step value certification process does not compare certified versus bin-run seed. used study derived commercial production fields (i.e., high quality seed) fields, which are usually case for
