Breaking Corn Yield Barriers: A Cropping Systems Approach, G. R. Balboa, I. A. Ciampitti Jan 2015

Breaking Corn Yield Barriers: A Cropping Systems Approach, G. R. Balboa, I. A. Ciampitti

Kansas Agricultural Experiment Station Research Reports

A corn research trial was conducted at Scandia, KS, during the 2014 growing season. The objective was to study the contribution of different farming systems in developing efficient and high-yielding corn production systems. The experiment had five treatments: farmer practices, comprehensive fertilization, production intensity, ecological intensification, and advanced plus. Farmer practice was the lowest-yielding treatment, and ecological intensification and advanced plus treatment presented similar yields.


Corn Yield Response To Water Availability, T. Newell, K. Roozeboom, G. J. Kluitenberg, I. A. Ciampitti Jan 2015

Corn Yield Response To Water Availability, T. Newell, K. Roozeboom, G. J. Kluitenberg, I. A. Ciampitti

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 …


Cover Crop Impacts On Soil Water Status, M. Kuykendall, K. Roozeboom, G. J. Kluitenberg, P. V. Vara Prasad Jan 2015

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 …


Soybean Planting Date × Maturity Group: Eastern Kansas Summary, I. A. Ciampitti, D. E. Shoup, G. Sassenrath, J. Kimball, E. A. Adee Jan 2015

Soybean Planting Date × Maturity Group: Eastern Kansas Summary, I. A. Ciampitti, D. E. Shoup, G. Sassenrath, J. Kimball, E. A. Adee

Kansas Agricultural Experiment Station Research Reports

Optimum planting time for soybean depends on the interaction between genotype and environment (G × E). Four field studies were conducted during the 2014 growing season across eastern Kansas (Manhattan, Topeka, Ottawa, and Parsons). This study explores the impact of planting date (early, mid, and late planting times) on yield for modern soybean cultivars from a range of maturity groups (early, medium, and late groups).


Nitrogen, Phosphorus, And Potassium Fertilization For Newly Established Tall Fescue, D. W. Sweeney, J. L. Moyer Jan 2015

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.


Response Of Wheat To Residual Fertilizer Nitrogen Applied To Previously Failed Corn, D. W. Sweeney, D. Ruiz Diaz Jan 2015

Response Of Wheat To Residual Fertilizer Nitrogen Applied To Previously Failed Corn, D. W. Sweeney, D. Ruiz Diaz

Kansas Agricultural Experiment Station Research Reports

When drought conditions result in poor corn growth and yield, the potential exists for carryover of fertilizer nitrogen (N) to wheat. Soil sampling at the wheat jointing stage showed that NO3-N levels increased slightly as previous N rate increased up to 240 lb/a N, but did not appear sufficient for the wheat yield increase to previous N rate. The relationship between wheat normalized difference vegetative index (NDVI) measurements at jointing and wheat yield was linear. The use of crop active sensors such as the GreenSeeker (Trimble Navigation Ltd., Sunnyvale, CA) may provide plant response data to supplement soil …


Surface Runoff Characteristics From Claypan Soil In Southeastern Kansas Receiving Different Plant Nutrient Sources And Tillage, D. W. Sweeney, Philip Barnes, Gary Pierzynski Jan 2015

Surface Runoff Characteristics From Claypan Soil In Southeastern Kansas Receiving Different Plant Nutrient Sources And Tillage, D. W. Sweeney, Philip Barnes, Gary Pierzynski

Kansas Agricultural Experiment Station Research Reports

Preliminary results show that two-year average total nitrogen (N) runoff losses and ortho-phosphorus (P) and total P runoff losses in the second year were greater with N-based turkey litter/no-till applications than P-based turkey litter or fertilizer-only applications. Incorporation of turkey litter applied based on N requirements resulted in N and P losses that did not differ from losses from P-based or fertilizer-only treatments. Chemical and statistical analyses of third-year samples will allow for final results and interpretation.


Tillage And Nitrogen Placement Effects On Yields In A Short-Season Corn/Wheat/Double-Crop Soybean Rotation, D. W. Sweeney Jan 2015

Tillage And Nitrogen Placement Effects On Yields In A Short-Season Corn/Wheat/Double-Crop Soybean Rotation, D. W. Sweeney

Kansas Agricultural Experiment Station Research Reports

In 2013, late planting resulted in corn yields that were less than 100 bu/a. Nitrogen (N) placement did not affect yields in the higher-yielding conventional tillage system, but knifing tended to result in greater yield in reduced and no-till systems.


Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Corn, A. Schlegel, H. D. Bond Jan 2015

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 …


Nitrogen And Sulfur Fertilization Effects On Camelina Sativa In West Central Kansas, E. Obeng, A. Obour Jan 2015

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 …


Corn Response To Foliar-Applied Zinc Fertilizers, A. Lamb, N. O. Nelson Jan 2015

Corn Response To Foliar-Applied Zinc Fertilizers, A. Lamb, N. O. Nelson

Kansas Agricultural Experiment Station Research Reports

This study was conducted to determine corn response to three foliar-applied zinc sources. The study was conducted on dryland corn in Manhattan, KS, during the 2014 growing season. Yields were low as a result of very low precipitation during pollination and grain fill. There was no yield response to foliar-applied Zn; however, grain analysis show significant increases in grain Zn concentration from foliar-applied Zn. Foliar-applied Zn products are effective for increasing Zn uptake in corn. Additional studies need to be conducted to determine the yield response.


Effects Of Various Forage Systems On Grazing And Subsequent Finishing Performance, L. W. Lomas, J. L. Moyer Jan 2015

Effects Of Various Forage Systems On Grazing And Subsequent Finishing Performance, L. W. Lomas, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

A total of 200 mixed black yearling steers were used to compare grazing and subsequent finishing performance from pastures with ‘MaxQ’ tall fescue, a wheat-bermudagrass double-crop system, or a wheat-crabgrass double-crop system in 2010, 2011, 2012, 2013, and 2014. Daily gains of steers that grazed ‘MaxQ’ tall fescue, wheat-bermudagrass, or wheat-crabgrass were similar (P>0.05) in 2010, daily gains of steers that grazed wheat-bermudagrass or wheat-crabgrass were greater (P>0.05) than those that grazed ‘MaxQ’ tall fescue in 2011 and 2012, daily gains of steers that grazed wheat-crabgrass were greater (P>0.05) than those that grazed wheat-bermudagrass …


Seeded Bermudagrass Cultivar Evaluation, J. L. Moyer Jan 2015

Seeded Bermudagrass Cultivar Evaluation, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

A year after seeding, the stand of ‘F.K.#1’ appeared better than stands of 10 of the other 13 seeded entries. By fall, 2014, stands of ‘KF-13A,’ ‘KF-13B,’ and ‘SWI-800’ along with ‘F.K.#1’ were better than stands of four of the other seeded entries. Late-summer production was higher for KF-13A and ‘Midland 99,’ the sprigged check, than for five of the other entries.


Nitrogen Management For Teff Hay Production, D. H. Min, J. L. Moyer Jan 2015

Nitrogen Management For Teff Hay Production, D. H. Min, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

Fertilization of teff with nitrogen (N) resulted in increased forage production, but amounts above 25 lb/a did not often increase yields in this study. Urea as the N source produced at least as much yield response as the alternate, an extended source of nitrogen (ESN).
