Seeding Date Effects On Camelina Seed Yield And Quality Traits, E. Obeng, A. Obour
Seeding Date Effects On Camelina Seed Yield And Quality Traits, E. Obeng, A. Obour
Kansas Agricultural Experiment Station Research Reports
Identifying crops that are adapted to dryland environments of the central and northern Great Plains (GP) has been a major challenge. An alternative crop with potential for dryland crop production in the GP is camelina (Camelina sativaL. Crantz). Time of planting is an important management consideration that can affect camelina production. Early planting allows camelina to mature before the onset of hot summer temperatures in the central GP that can affect seed yield. A study was carried out in the spring of 2013 and 2014 to evaluate planting date effects on spring camelina varieties grown under dryland conditions …

Influence Of Different Seeding Dates On Fenugreek (Trigonella Foenum-Graecum L.) Forage Yield And Nutritive Value, A. Obour, E. Obeng, J. D. Holman
Kansas Agricultural Experiment Station Research Reports
Fenugreek (Trigonella foenum-graecum L.) is used as medicinal plant in many Asian countries and has been reported to have forage quality similar to alfalfa. Fenugreek is an annual crop and may have the potential to diversify forage production systems in the central High Plains. This study evaluated forage dry matter (DM) production and the nutritive value of three fenugreek cultivars as influenced by planting date at Hays and Garden City, KS, in 2014. Results at Hays showed forage DM yield of fenugreek cultivars was not affected by planting date, but fenugreek cultivars differed significantly (P<0.05) in forage DM yield. Averaged across planting date, forage DM production was 760 lb/a for ‘Amber,’ 910 lb/a for ‘F96,’ and 672 lb/a for ‘Tristar.’ Forage crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrient (TDN) concentrations, and relative feed value (RFV) did not differ (P>0.05) …

Corn Yield Response To Plant Populations, D. E. Shoup, E. A. Adee, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
Corn hybrid development with a focus on drought tolerance has emerged in recent years, and producers have questions about their yield performance across a range of plant populations. A two-year study was conducted to determine the yield of corn hybrids across several plant populations. Corn hybrids responded differently in 2013 and 2014. In 2013, a lower yield environment occurred. The hybrid with drought tolerance had the greatest yield of 95 bu/a at a plant population of 21,500 plants/a, whereas the non-drought-tolerant hybrid’s greatest yield was 90 bu/a at a plant population of 13,500 plants/a. In 2014, the yield environment was …

Yield gaps can be understood as the difference between maximum and attainable on-farm yields. The approach taken in this project is system wide, rather than focusing on one factor and its interaction. The factors that were tested include narrow row spacing; plant population; balanced nutrition practices, including various timings of nitrogen, phosphorus, and potassium (NPK) and micronutrient applications; crop protection with fungicide and insecticide applications; plant growth regulator effects; …
Cover Crop Impacts On Soil Water Status, M. Kuykendall, K. Roozeboom, G. J. Kluitenberg, P. V. Vara Prasad
Cover Crop Impacts On Soil Water Status, M. Kuykendall, K. Roozeboom, G. J. Kluitenberg, P. V. Vara Prasad
Kansas Agricultural Experiment Station Research Reports
Water is a primary concern for producers in the Great Plains; as such, research is warranted to quantify how much cover crops affect the amount of soil water available to subsequent cash crops. Cover crop mixes have been marketed as a means to conserve water in no-till cropping systems following winter wheat (Triticum aestivumL.) harvest. The objectives of this study are to quantify changes in soil profile water content in the presence of different cover crops and mixtures of increasing species complexity, to quantify their biomass productivity and quality, and to quantify the impact of cover crops on …

More recently, menthol and other essential oils have been identified as potential alternatives to feed antibiotics and growth promotants. Menthol has been observed to directly affect κ-opioid receptors. Kappa opioid receptors are located in the central nervous system, with a high density …
Nitrogen, Phosphorus, And Potassium Fertilization For Newly Established Tall Fescue, D. W. Sweeney, J. L. Moyer
Nitrogen, Phosphorus, And Potassium Fertilization For Newly Established Tall Fescue, D. W. Sweeney, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
First-year spring yields of tall fescue in 2013 responded to phosphorus (P) fertilization, but lodging at the R5 growth stage in the spring with higher P fertilization rates may have influenced subsequent fall harvest yields, which declined with increasing P rates. As N rates increased, R5 yields declined but fall harvest yields increased.
Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Corn, A. Schlegel, H. D. Bond
Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Corn, A. Schlegel, H. D. Bond
Kansas Agricultural Experiment Station Research Reports
Long-term research shows that phosphorus (P) and nitrogen (N) fertilizer must be applied to optimize production of irrigated corn in western Kansas. In 2014, N applied alone increased yields 58 bu/a, whereas P applied alone increased yields only 12 bu/a. Nitrogen and P applied together increased yields up to 152 bu/a. This is slightly above the 10-year average, where N and P fertilization increased corn yields up to 146 bu/a. Application of 120 lb/a N (with P) produced about 91% of maximum yield in 2014, which was similar to the 10-year average. Application of 80 instead of 40 lb P2O5/a …

Identification Of Yield-Limiting Factors In Southeast Kansas Cropping Systems, G. F. Sassenrath, X. Lin, D. E. Shoup
Kansas Agricultural Experiment Station Research Reports
Crop performance and yield within production fields varies as a function of growing environment and soil properties within the field. Components contributing to yield in corn, wheat, and soybean production were examined through on-farm measurements of soil properties in southeast Kansas. Additional tests in research plots explored components contributing to yield in greater detail. Environmental variability between the 2013 and 2014 growing seasons contributed to differences in yield. Additional variability in soil parameters influenced crop performance, particularly for soils high in clay content.
Effects Of Seed Treatment On Sudden Death Syndrome Symptoms And Soybean Yield, E. A. Adee
Effects Of Seed Treatment On Sudden Death Syndrome Symptoms And Soybean Yield, E. A. Adee
Kansas Agricultural Experiment Station Research Reports
Sudden death syndrome (SDS) is a soybean disease that perennially limits yields in the Kansas River Valley. The presence of soybean cyst nematode (SCN) and saturated soils have been implicated in contributing to the severity of the disease. Selecting varieties with some degree of tolerance to SDS is the only cultural practice that can potentially reduce the severity of SDS and improve yields. Variety selection alone, however, cannot improve the production of soybeans to make them profitable. The challenge of trying to manage irrigation scheduling to avoid saturated soils further complicates efforts to increase productivity with irrigation while still avoiding …

Late-Season Nitrogen Fertilizer Application In Soybean, G. R. Balboa, D. R. Hodgins, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
Field experiments were conducted at the North Central Kansas Experiment Field near Scandia, KS, in the summer of 2014 to evaluate effect of late-season nitrogen (N) fertilizer application on modern soybean genotypes under dryland and irrigated environments. The main objective was to determine if the N application late in the season has an agronomical benefit to soybean producers. A unique fertilizer N source (urea) was applied at five N rates (0, 40, 80, 120, and 160 lb N/a) to soybean at the R3 growth stage. Overall soybean yields under dryland conditions ranged from 73 to 89 bu/a, whereas yield variation …

Kansas Agricultural Experiment Station Research Reports
Drought-tolerant technologies have become popular in hybrids for low-yielding corn environments across central and western Kansas and are marketed for their ability to produce higher grain yields with less water. The objective of this study was to compare water use, yield, and water use efficiency (WUE) of two types of drought-tolerant (DT) corn hybrids and a high-yielding non-DT hybrid. Water use and yield of two DT and one non-DT, high-yielding hybrid were compared in both dryland and irrigated situations. The average yield for the irrigated corn was 217 bu/a, and the average was 127 bu/a in dryland, representing a yield …
