Co2 Flux And C Balance Due To The Replacement Of Bare Soil With Agro-Ecological Service Crops In Mediterranean Environment, Emanuele Radicetti, O. Adewale Osipitan, Ali Reza Safahani Langeroodi, Sara Marinari, Roberto Mancinelli
Co2 Flux And C Balance Due To The Replacement Of Bare Soil With Agro-Ecological Service Crops In Mediterranean Environment, Emanuele Radicetti, O. Adewale Osipitan, Ali Reza Safahani Langeroodi, Sara Marinari, Roberto Mancinelli
Haskell Agricultural Laboratory (Northeast Research and Extension Center)
Intensive agriculture practices often results in decomposition of organic matter, thus causing soil CO2 emissions. Agro-ecological service crop could be profitably cultivated to improve soil characteristics and reduce CO2 emissions under Mediterranean environment. Two-year field trials were conducted in central Italy. The treatments were three agro-ecological service crops (hairy vetch, oat, and oilseed rape) and a no-service cover. Plant development, soil characteristics, and CO2 emissions were measured. Oat and oilseed rape showed a rapid growth, while hairy vetch started to grow rapidly only after the cold period. Soil CO2 emissions trend was similar among the agro-ecological …

Nitrogen And Weed Management In Transplanted Tomato In The Nigerian Forest-Savanna Transition Zone, J. A. Adigun, O. S. Daramola, O. R. Adeyemi, P. M. Olorunmaiye, O. A. Osipitan
Haskell Agricultural Laboratory (Northeast Research and Extension Center)
Weed infestation and inherent low soil fertility are among primary reasons for low yields of tomato in Nigeria. Field trials were carried out during the wet season of 2015 and 2016 to evaluate yield response of tomato to nitrogen (N) application and weed control methods in the forest-savanna transition zone of Abeokuta, Nigeria. Positive relationship exists between growth of weed species and increase in N application. Across the years of study, increase in N up to 90 kg/ha increased weed density by 11–25%, however, the increased N gave the transplanted tomato competitive advantage and thus enhanced weed smothering. Pre-transplant application …
Case Study: Feed Intake And Performance Of Heifers Sired By High- Or Low-Residual Feed Intake Angus Bulls, J. Minick Bormann, D. W. Moser, T. T. Marston
Case Study: Feed Intake And Performance Of Heifers Sired By High- Or Low-Residual Feed Intake Angus Bulls, J. Minick Bormann, D. W. Moser, T. T. Marston
Haskell Agricultural Laboratory (Northeast Research and Extension Center)
The objective of this project was to investigate the effects of selecting sires for residual feed intake (RFI) on the performance of their daughters. Bulls with low or high estimated breeding values (EBV) for RFI were selected from the Angus Society of Australia sire summary and mated to Angus cross commercial cows at the Kansas State University Cow-Calf Unit in 2005 and 2006. The average EBV of low- and high-RFI bulls were −0.55 and 0.27 kg DM, respectively. Heifers born in 2006 were tested for feed intake in 2 groups (n = 24, n = 26), and heifers born in …

The Northeast Station ... 25 Years Of Research, Extension And Service
Haskell Agricultural Laboratory (Northeast Research and Extension Center)
For the past 25 years, the Northeast Station at Concord has served as the cornerstone of University of Nebraska agricultural research and Extension activity in northeast Nebraska. This year marks the twenty fifth anniversary of the founding of the station and commemorates the dedication of the citizens of this area in their commitment to its success.
While the land the station occupies may not look different from its surroundings, its purpose is. The Northeast Station operates as a part of a statewide agricultural experiment station and Cooperative Extension Service network. The mission of the station is to research agricultural topics …

Effects Of Removal And Remixing Of Heavyweight Pigs On Performance To Slaughter Weights, M. C. Brumm, L. J. Johnston, D W. Rozeboom
Effects Of Removal And Remixing Of Heavyweight Pigs On Performance To Slaughter Weights, M. C. Brumm, L. J. Johnston, D W. Rozeboom
Haskell Agricultural Laboratory (Northeast Research and Extension Center)
An experiment was conducted to determine the effects of heavyweight pig removal and remixing on performance. The experiment used a total of 450 pigs (31 kg initial BW) that were sorted and remixed at a mean replicate BW of 73 kg. Treatments were 15 pigs/pen from initial BW to slaughter (15S), 20 pigs/pen from initial BW to time of sort and remix, then reduced to 15 pigs/pen (20/ 15), and 15 pigs/pen from time of sort and remix to slaughter, comprised of the 5 heaviest pigs from each of three 20/15 pens per replicate (15M …

Case Study: Tympanic Temperature And Behavior Associated With Moving Feedlot Cattle, T. L. Mader, M. S. Davis, W. M. Kreikemeier
Haskell Agricultural Laboratory (Northeast Research and Extension Center)
Body temperature is often used as an indicator of animal health status. In a series of handling experiments, tympanic temperatures (TT) were obtained in unrestrained feedlot cattle. In a January experiment (BW = 531 ± 54 kg), TT were increased (P
Oviposition By European Corn Borer (Lepidoptera: Crambidae) In Response To Various Transgenic Corn Events, Richard L. Hellmich, L. S. Higgins, John F. Witkowski, J. E. Campbell, L. C. Lewis
Oviposition By European Corn Borer (Lepidoptera: Crambidae) In Response To Various Transgenic Corn Events, Richard L. Hellmich, L. S. Higgins, John F. Witkowski, J. E. Campbell, L. C. Lewis
Haskell Agricultural Laboratory (Northeast Research and Extension Center)
Oviposition preference by European corn borers, Ostrinia nubilalis (Hübner), for or against transgenic corn would influence amounts of refuge required for resistance management. The objective of this research was to determine if various Bacillus thuringiensis (Bt) corn transgenic events influence O. nubilalis oviposition. All commercially available events (currently 5) were evaluated, plus 1 experimental event. Results from 3 independent studies are reported, including 3 field-cage experiments with vegetative corn, 2 field-cage experiments with reproductive corn, and 2 field experiments with natural O. nubilalis on reproductive corn. In each case, Bt corn hybrids are compared with their near isogenic hybrids by …

Feedlot Diet Roughage Level For Hereford Cattle Exposed To Excessive Heat Load1, T. L. Mader, J. B. Gaughan, B A. Young
Haskell Agricultural Laboratory (Northeast Research and Extension Center)
In Exp. 1, six individually fed Hereford steers were exposed to hot (HOT) or thermoneutral (TNL) environmental conditions (ENV) while being adapted (stepped-up) to a finishing diet by decreasing roughage level from 55 to 10% of the diet DM over 17 d. Only at 10% roughage did heat exposure result in reduced (P

Manure Distribution Field Day
Haskell Agricultural Laboratory (Northeast Research and Extension Center)
As the livestock industry in the midwest undergoes rapid change, issues associated with the storage and land application of the manure have increasingly become a focus of public concern. Both USDA and Land Grant Universities have increased their efforts in addressing the concerns raised in recent years.
The Manure Distribution Field Day on August 28, will highlight many of the research efforts currently underway at the University of Nebraska, Iowa State University, and South Dakota State University. Manure storage systems, land application equipment, and odor control associated with livestock systems will be highlighted. You will be able to view displays …

New Unit's First Job: Spacing For 300-Pound Market Weight
Haskell Agricultural Laboratory (Northeast Research and Extension Center)
You’re looking at the interior of what’s called a “double-wide” swine finishing unit unveiled at the University of Nebraska Northeast Research and Extension Center open house, at Concord, in late June.
Northeast Center swine specialist Mike Brumm says the first study in the new research unit will look at space requirements for feeding pigs to a market weight of 300 pounds under all-in-all out operation. Various pen size and number combinations will be the focus of future research in the unit which can be divided into the following arrangements: Eight pens, each 14 by 16 feet; 16 pens, each 8 …
