Summary Implementing strategic tillage (ST) in otherwise long-term no-till (NT) systems could control herbicide resistant weeds and increase profitability of crop production in semi-arid dryland cropping systems. For the purpose of this study, ST is defined as a single tillage event (once every 6-10 years) in an otherwise NT system to reduce density of herbicide tolerant grass weeds. However, there is little information on the long-term (>5 years) effects of ST on soil health parameters and crop yields. This study used long-term tillage and crop rotation plots established in 1976 at the Kansas State University Agriculture Research Center in Hays, KS. Treatments include three rotations: continuous wheat (WW), wheat-sorghum-fallow (WSF), and wheat-fallow (WF); and two tillage regimes: no-till (NT) and reduced tillage (RT). In 2016, a new tillage treatment, ST, was added to control herbicide resistant (HR) grass weeds and to mix soil to reduce nutrient and pH stratification. Soil samples were collected following wheat harvest in 2022 to investigate soil properties after 5 years of ST. Results of the 2022 sampling showed rotation and tillage had no significant effect ( P > 0.05) on bulk density. However, bulk density was least in the 0-to-2-inch soil depth compared to the 2-to 6-inch and 6-to 12-inch depths, with values of 1.16, 1.44, and 1.39 g/cm 3 , respectively. Soil organic carbon (SOC) was greatest in the 0-to 2-inch soil depth. The SOC concentration in soils under NT was not different compared to ST, whereas soils under RT had 8% less SOC than NT. Wind-erodible fraction (WEF) was not different among tillage

Almond hulls contain soluble sugars and could potentially be used as a feed ingredient in beef cattle diets. Three-hundred sixty-four steers [initial body weight (BW) 567 ± 45.7 lb] were blocked by source (4) and assigned to one of four treatments to determine the effects of almond hull inclusion on growth performance of limit-fed beef cattle. The control diet (CON) contained [dry matter (DM) basis] 39.5% dry-rolled corn, 7.5% supplement, 40% wet-corn gluten feed, and 13% prairie day. Non-pro-cessed almond hulls replaced prairie hay and were fed at 13% of dietary DM (13AH) or replaced prairie hay and a proportion of dry-rolled corn and were fed at 26% of dietary DM (26AH). In addition, a subset of almond hulls was processed using a grinder mixer with no screen. Processed almond hulls replaced prairie hay and were fed at 13% of dietary DM (13PAH). Steers were limit-fed at 2.2% of BW daily (DM basis) for a 56-day growing period. Individual BW were measured on days 0, 14, and 56. Body weights following the 56-day feeding period were greater ( P < 0.01) in 13AH and 13PAH compared with 26AH. In addition, BW on day 56 tended ( P = 0.10) to be greater in 13PAH compared with CON. Average daily gains and DM intakes from days 0 to 56 were greater ( P ≤ 0.05)

The objective of this study was to explore the effects of different time and temperature accelerated aging (AA) treatments on beef tenderness, yield, microbial quantity, and enzyme activity on lower quality beef cuts. The shoulder clod and top round muscles were collected from 10 U.S. Department of Agriculture choice beef carcasses, fabricated into steaks, and assigned to one of six treatments: 3 days postmortem (control), cooler aged for 21 days, AA 120°F for 2 h, AA 120°F for 3 h, AA 130°F for 2 h, and AA 130°F for 3 h. Yield calculation, aerobic plate counts, instrumental tenderness, cathepsin enzyme activity, and collagen analysis were performed. All AA treatments effectively decreased microbial loads on the steak surface and in purge ( P < 0.05). The AA steaks exhibited lower yield compared to the cooler aged steaks or control ( P < 0.01). All AA treatments improved tenderness of the samples compared to the control ( P < 0.01) with most exhibiting similar tenderness as the 21-day cooler aged treatment. The amount of collagen present in the purge was greater in AA samples compared to the cooler aged samples ( P < 0.01). Finally, it was interesting to point out that AA 120°F at 3 h seem to stimulate the most cathepsin enzyme activity among the treatments in beef ( P < 0.01).

Weed control after planting warm-season grasses in the spring can be critical for acceptable establishment of the stand. However, many herbicide labels can be unclear on sprigging restrictions before or after the application of a product. Research was conducted on the growth effects of pre-and postemergence herbicides applied at or near the day of ‘Innovation’ zoysiagrass sprigging. Preliminary data from this study showed granular (Ronstar G) and liquid (Ronstar Flo) formulations of oxadiazon caused the least amount of injury to zoysiagrass.
