Wheat And Grain Sorghum In Four-Year Rotations, A. Schlegel, J. D. Holman, C. Thompson

Kansas Agricultural Experiment Station Research Reports

In 1996, an effort began to quantify soil water storage, crop water use, and crop productivity on dryland systems in western Kansas. Research on 4-year crop rotations with wheat and grain sorghum was initiated at the Southwest Research-Extension Center near Tribune, KS. Rotations were wheat-wheat-sorghum-fallow (WWSF), wheatsorghum- sorghum-fallow (WSSF), and continuous wheat (WW). Soil water at wheat planting averaged about 9 in. following sorghum, which is about 3 in. more than the average for the second wheat crop in a WWSF rotation. Soil water at sorghum planting was only about 1 in. less for the second sorghum crop compared with …

Alternative Cropping Systems With Limited Irrigation, A. Schlegel Jan 2017

Alternative Cropping Systems With Limited Irrigation, A. Schlegel

Kansas Agricultural Experiment Station Research Reports

A limited irrigation study involving four cropping systems and evaluating four crop rotations was initiated at the Southwest Research-Extension Center near Tribune, KS, in 2012. The cropping systems were two annual systems (continuous corn [C-C] and continuous grain sorghum [GS-GS]) and two 2-year systems (corn-grain sorghum [CGS]) and corn-winter wheat [C-W]). In 2016, corn yields were similar in all rotations, as were grain sorghum yields. This tended to agree with the 4-yr average yields, except for average grain sorghum yields being higher following corn than grain sorghum.

Exploring The Value Of Plant Analysis To Enhance Water Use Efficiency In Southwest Kansas, A. J. Foster, I. Kisekka, B. Golden Jan 2017

Exploring The Value Of Plant Analysis To Enhance Water Use Efficiency In Southwest Kansas, A. J. Foster, I. Kisekka, B. Golden

Kansas Agricultural Experiment Station Research Reports

Nutrient deficiency is identified by use of visual symptoms. However, the application of the proposed deficient nutrient often does not result in the correction of the observed visual symptoms. This is because essential nutrients do not operate independently of each other or independently of the overall plant health and growing conditions. A study was initiated in 2016 at the Kansas State University Southwest Research-Extension Center Finnup Farm near Garden City, KS, to use both soil and plant analyses to identify toxicities or hidden deficiencies that could be limiting corn yield at various irrigation capacities. Soil samples prior to planting and …

Winter And Early Spring Herbicides For Kochia Control In Fallow, R. Currie, P. Geier Jan 2017

Winter And Early Spring Herbicides For Kochia Control In Fallow, R. Currie, P. Geier

Kansas Agricultural Experiment Station Research Reports

A study was initiated near Garden City, KS, in fall of 2015 and spring of 2016 comparing the weed control of several herbicide treatments and their time of application for kochia control in fallow. All herbicide treatments applied in December 2015 provided 99 or 100% kochia control in early spring. However, control declined to less than 60% with these treatments by June 8, 2016. Spring-applied herbicides were generally more efficacious than winter-applied herbicides on June 8, with the best control from treatments of Clarity (dicamba) plus atrazine with or without Zidua (pyroxasulfone) (88 to 89%).

Postemergence Weed Control With Diflexx, Diflexx Duo, Capreno, And Atrazine In Corn Resistant To Glufosinate And Glyphosate, R. Currie, P. Geier Jan 2017

Postemergence Weed Control With Diflexx, Diflexx Duo, Capreno, And Atrazine In Corn Resistant To Glufosinate And Glyphosate, R. Currie, P. Geier

Kansas Agricultural Experiment Station Research Reports

A study was initiated near Garden City, KS, in 2016, comparing the weed control of several postemergence herbicide treatments in irrigated corn. Control of kochia, Palmer amaranth, and crabgrass was 96% or more effective with all herbicides at 7 days after treatment (DAT). By 62 DAT, control of these three weed species was generally best when glyphosate, atrazine, Diflexx (dicamba) or Clarity (dicamba) were included in the herbicide mixture. Although all herbicide tank mixes increased yield compared to the untreated plots, no tank mix resulted in a superior yield.

Palmer Amaranth (Amaranthus Palmeri) Suppression With Half Rates Of Dicamba And Atrazine With Increasing Sorghum (Sorghum Bicolor) Density And Nitrogen Rate, I. B. Cuvaca, R. Currie, A. J. Foster

Kansas Agricultural Experiment Station Research Reports

Palmer amaranth (PA) competition can result in severe yield loss in grain sorghum. Increasing sorghum density and nutrient supply could promote early/rapid canopy closure and therefore reduce the amount of light that could otherwise penetrate the canopy and promote PA growth in sorghum. A study was conducted at the Southwest Research-Extension Center near Garden City, KS, to determine if PA could be suppressed with dicamba and atrazine applied as PRE at half rates combined with increasing sorghum density (60,000, 90,000, and 120,000 seeds/a), and nitrogen rate (0, 100, 200 lb/a). Preliminary results indicate that increasing plant density and nitrogen rate …

Effects Of Interseeding Ladino Clover Into Tall Fescue Pastures Of Varying Endophyte Status On Grazing Performance Of Stocker Steers, L. W. Lomas, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

Sixty-four yearling steers grazing tall fescue pastures were used to evaluate the effects of fescue cultivar and interseeding ladino clover on grazing gains and available forage. Fescue cultivars evaluated were high-endophyte ‘Kentucky 31,’ low-endophyte ‘Kentucky 31,’ ‘HM4,’ and ‘MaxQ.’ Steers that grazed pastures of low-endophyte ‘Kentucky 31,’ ‘HM4,’ or ‘MaxQ’ gained significantly more (P<0.05) and produced more (P<0.05) gain/a than those that grazed high-endophyte ‘Kentucky 31’ pastures. Gains of cattle that grazed low-endophyte ‘Kentucky 31,’ ‘HM4,’ or ‘MaxQ’ were similar (P>0.05). High-endophyte ‘Kentucky 31’ pastures had more (P<0.05) available forage than lowendophyte ‘Kentucky 31,’ ‘HM4,’ or ‘MaxQ’ pastures.
