Identification Of Yield-Limiting Factors In Southeast Kansas Cropping Systems, G. F. Sassenrath, X. Lin, D. E. Shoup
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.

Determining Profitable Annual Forage Rotations, J. D. Holman, T. Roberts, S. Maxwell
Kansas Agricultural Experiment Station Research Reports
Producers are interested in growing forages, yet the southwest region of Kansas lacks proven recommended crop rotations such as those for grain crops. Forage production is important to the region’s livestock and dairy industries and is becoming increasingly important as irrigation well capacity declines. Forages require less water than grain crops and may allow for increased cropping intensity and opportunistic cropping. A study was initiated in 2013 comparing several 1-, 3-, and 4-year forage rotations with no-till and minimum-till (min-till). Data presented are from 2013 through 2014. Winter triticale yields were not affected by tillage in 2013 but were increased …
Wheat And Grain Sorghum In Four-Year Rotations, A. Schlegel, J. D. Holman, C. Thompson
Wheat And Grain Sorghum In Four-Year Rotations, A. Schlegel, J. D. Holman, C. Thompson
Kansas Agricultural Experiment Station Research Reports
Research on 4-year crop rotations with wheat and grain sorghum was initiated in 1996 at the Southwest Research-Extension Center near Tribune, Kansas. Rotations were wheat-wheat-sorghum-fallow (WWSF), wheat-sorghum-sorghum-fallow (WSSF), and continuous wheat (WW). Soil water at wheat planting averaged about 9 inches following sorghum, which is about 3 inches more than the average for the second wheat crop in a WWSF rotation. Soil water at sorghum planting was only about 1 inch less for the second sorghum crop compared with sorghum following wheat. Grain yield of recrop wheat averaged about 80% of the yield of wheat following sorghum. Grain yield of …
Breaking Soybean Yield Barriers: A Cropping Systems Approach, G. R. Balboa, I. A. Ciampitti
Breaking Soybean Yield Barriers: A Cropping Systems Approach, G. R. Balboa, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
Two soybean research trials were conducted at Scandia, KS, in dryland and irrigated environments. The objective of this trial was to study the contribution of different farming systems to developing efficient and high-yielding soybean production systems. Each experiment had five treatments: farmer practices (FP), comprehensive fertilization (CF), production intensity (PI), ecological intensification (CF + PI), and advanced plus (AD). Under dryland, FP and CF treatments yielded 34 bu/a, differing in 27 bu/a compared with PI, EI, and AD scenarios. Under irrigation, FP and CF presented comparable yield levels, differing by close to 36 bu/a compared with crop intensification treatments (CF …
Large-Scale Dryland Cropping Systems, A. Schlegel
Large-Scale Dryland Cropping Systems, A. Schlegel
Kansas Agricultural Experiment Station Research Reports
A large-scale dryland cropping systems research and demonstration project at the Southwest Research-Extension Center near Tribune, Kansas, evaluated two summer crops (corn and grain sorghum) along with winter wheat in crop rotations varying in length from 1 to 4 years. The rotations were continuous grain sorghum, wheat-fallow, wheat-corn-fallow, wheat-sorghum-fallow, wheat-corn-sorghum-fallow, and wheatsorghum- corn-fallow. The objective of the study is to identify cropping systems that enhance and stabilize production in rain-fed locations to optimize economic crop production. Averaged across the past 7 years, wheat yields ranged from 22 to 25 bu/a and were not affected by length of rotation. Corn and …
Long-Term No-Till In A Wheat-Sorghum-Fallow Rotation, A. Schlegel, L. Stone
Long-Term No-Till In A Wheat-Sorghum-Fallow Rotation, A. Schlegel, L. Stone
Kansas Agricultural Experiment Station Research Reports
Grain yields of wheat and grain sorghum increased with decreased tillage intensity in a wheat-sorghum-fallow (WSF) rotation. In 2014, available soil water at wheat planting was 2 inches greater for no-till (NT) than for reduced-tillage (RT) or conventional tillage (CT). For grain sorghum in 2014, available soil water at planting was greatest with RT and least with CT. Averaged across the 14-year study, available soil water at wheat and sorghum planting was similar for RT and NT and about 1 inch greater than CT. Averaged across the past 14 years, NT wheat yields were 5 bu/a greater than RT and …
