Wheat Variety Yield Response To Nitrogen And Sulfur Rates During The 2019–2020 Growing Season, B. R. Jaenisch, T. Wilson, N. Nelson, M. Guttieri, R. P. Lollato
Kansas Agricultural Experiment Station Research Reports
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 …
Corn Yield Response To Sulfur Applied With Nitrogen Fertilizer, T. E. Husa, D. A. Ruiz Diaz
Corn Yield Response To Sulfur Applied With Nitrogen Fertilizer, T. E. Husa, D. A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
The objective of this study was to evaluate the effect of nitrogen (N) with added sulfur (S) fertilizer on corn yield. The treatments included 1) a control with no sulfur and no nitrogen; 2) urea ammonium nitrate (UAN) (180 lb N/a; 0 lb S/a); and 3) UAN plus ammonium thiosulfate (ATS) (180 lb N/a; 15 lb S/a). Both the UAN and UAN+ATS were balanced to 180 lb N/a. These three treatments were evaluated at two locations in 2019 and three locations in 2020. Preliminary results show that yield trended upward with the application of nitrogen plus sulfur fertilization over N …

Co-Inoculation And Sulfur Fertilization In Soybeans, L. H. Moro Rosso, A. F. De Borja Reis, S. L. Naeve, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
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 …

Fertilizer Source And Rate Affect Sulfur Uptake And Yield Response In Corn, T. E. Husa, D. A. Ruiz Diaz
Fertilizer Source And Rate Affect Sulfur Uptake And Yield Response In Corn, T. E. Husa, D. A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
With sulfur deficiencies being found throughout Kansas, the evaluation of sulfur fertilization and plant uptake are vital to optimize corn production. The objective of this study was to evaluate the effect of application rates of sulfur on yield and uptake in corn. Nutrient concentrations in corn biomass and grain were evaluated at the Kansas River Valley Experiment Field at Rossville, KS, in 2019. Five treatments were evaluated, including a control with no sulfur and no nitrogen (N), and four fertilizer treatments with 180 lb of nitrogen and four rates of sulfur fertilizer (0, 30, 50, and 200 lb S/a). The …

Wheat Grain Yield And Protein Concentration Response To Nitrogen And Sulfur Rates, Brent R. Jaenisch, Tara Wilson, Nathan O. Nelson, Mary Guttieri, Romulo P. Lollato
Kansas Agricultural Experiment Station Research Reports
Winter wheat is often double-cropped after soybeans in no-tillage systems. The soybean crop removes large quantities of sulfur (S), which might cause S deficiency for the following wheat crop. Our objective was to evaluate the responses of three wheat varieties to three nitrogen (N) and four S fertilizer rates representing a range of N:S ratios. The experiment was conducted near Ashland Bottoms and Hutchinson, KS. Treatments were arranged as a complete factorial structure with a split-split-plot design. Variety was the whole-plot, N was the sub-plot, and S was the sub-sub plot. Nitrogen rates were 50, 100, and 150% of the …

Wheat Grain Yield And Protein Response To Nitrogen And Sulfur Rates, B. R. Jaenisch, R. P. Lollato
Kansas Agricultural Experiment Station Research Reports
Winter wheat is often double-cropped after soybeans in no-tillage systems. The soybean crop removes large quantities of sulfur (S), which might unbalance ratios of nitrogen (N) to S for the following wheat crop. Our objective was to evaluate the responses of two wheat varieties to three N and four S rates representing a range of N:S ratios. The experiment was arranged as a complete factorial with a split-split-plot design. Variety was the whole-plot, N the sub-plot, and S the sub-sub plot. Nitrogen rates were 50, 100, and 150% of the recommended rate for 60 bu/a, which corresponded to ~45, 87, …
Nitrogen And Sulfur Fertilization Effects On Camelina Sativa In West Central Kansas, E. Obeng, A. Obour
Nitrogen And Sulfur Fertilization Effects On Camelina Sativa In West Central Kansas, E. Obeng, A. Obour
Kansas Agricultural Experiment Station Research Reports
Camelina sativais early maturing and possesses characteristics that make it a good fit as a rotation crop in dryland wheat cropping systems. Nitrogen (N) and sulfur (S) play very important roles in oilseed production, including camelina. This study was undertaken in 2013 and 2014 to determine N and S rates necessary for optimum camelina production in West Central Kansas. The experiment was set up as randomized complete blocks with four replications in a split-plot arrangement. Treatments were two S rates (0 and 18 lb/a) as the main plots, and N rates (0, 20, 40, and 80 lb/a) were the …
