Timing, Source, And Placement Of Nitrogen Fertilizer Increases Wheat Yield And Protein Content In High Yielding Environments, L. M. Simão, D. A. Ruiz Diaz, R. P. Lollato
Timing, Source, And Placement Of Nitrogen Fertilizer Increases Wheat Yield And Protein Content In High Yielding Environments, L. M. Simão, D. A. Ruiz Diaz, R. P. Lollato
Kansas Agricultural Experiment Station Research Reports
The efficiency of nitrogen (N) fertilizer management depends on rate, timing, placement, and source, but the benefits of an integrated program have not been clearly quantified, to our knowledge. This study aimed to investigate the effects of integrated N management on winter wheat grain yield, grain protein content, grain test weight, and biomass in Kansas. The study consisted of two N management treatments: Normal (single N application as UAN using broadcast nozzles with the absence of urea inhibitors); and Progressive (split N application into two timings using streamer bars with urease inhibitors). Both treatments had similar results in all variables …

Early spring visual sulfur (S) deficiency symptoms are increasingly a concern for Kansas wheat growers, but the extent of yield limitation due to S deficiencies and its interaction with nitrogen (N) supply is not well quantified in this environment. Our objective was to evaluate the responses of three wheat varieties to the interaction of N and S rates. The experiment was conducted in four Kansas locations during the 2019–2020 winter wheat growing season: Ashland Bottoms, Argonia, Belleville, and Hutchinson. These locations were selected to provide a range in soil textures and organic matter content, as these variables might impact the …

Soybeans [Glycine max(L.) Merr.] rely on large nutrient uptake, especially nitrogen (N), to produce seeds with high nutritional value. Biological N fixation (BNF) supplies most of the plant N demand and enhancement of this process might improve cropping systems’ sustainability. Although seed inoculation withBradyrhizobiumspp. for soybean crop is a well-known management practice, co-inoculation with the freeliving N-fixerAzospirillum brasilensehas not been deeply investigated in the US, to our knowledge. Thus, this research explores the effect of co-inoculation withA. brasilenseon soybean yield and seed nutritional quality (protein, oil, essential and sulfur (S) amino acids …
