Laveta Lockridge Recognized For Excellence in Extension

EFNEP Program Assistant Laveta Lockridge

Introducing Ms. Laveta Lockridge

EFNEP Program Assistant Laveta Lockridge will represent Lincoln University of Missouri in national competition for Excellence in Extension.

When asked about her “Excellence in Extension” nomination, Ms. Lockridge stated, “It has always been a dream and passion of mine to serve as a mentor for my community.” That dream became a reality over a decade ago when she began volunteering with Lincoln University Cooperative Extension (LUCE). At that time, Ms. Lockridge’s main reason in becoming a volunteer was because her children were participating in LUCE programs. But when her volunteer work evolved into a professional full-time position, Ms. Lockridge’s journey exemplified the true model of Cooperative Extension.

Ms. Lockridge has found multiple ways to advocate resources that would further enhance life skills or educational advancement. Providing guidance and strengthening life skills for those in Pemiscot County has always been the goal of Lockridge in her 11+ years with LUCE. Advocating for the underserved and disseminating information are the bases for her extensive influence as an Extension professional.

To be an effective educator, it is important to be able to communicate well with others. Ms. Lockridge takes initiative by participating in and facilitating events and opportunities when they are presented to her. These events helped to strengthen her public speaking skills, resulting in her own form of personal professional development.

Ms. Lockridge is a team player and very often assists her colleagues in the LUCE Caruthersville Outreach Center in facilitating programs. Working for LUCE is a wonderful way to discover our “yet to be discovered” abilities and talents by addressing the needs of others.

The entire Lincoln University Extension Team congratulates Ms. Laveta Lockridge!

Lincoln University Students Awarded at ARD Research Symposium

Article written by LU Writer/Editor Jenney Schaben

Lincoln University is a proud member of the Association of Research Directors (ARD), which is composed of 19 autonomous 1890 land grant universities. The ARD mission is to “provide visionary and enlightened leadership to member institutions as they continually address issues impacting their ability to provide innovative solutions to the food and agricultural research challenges facing the state, region, nation and world-at-large.”

ARD also coordinates opportunities for students and professionals to interact, share knowledge, and collaborate on research initiatives. This spring marked the 20th year for the ARD Research Symposium, an educational and inclusive conference where 1890 land grant students can come together to connect on research topics relevant to their studies.

From Left to Right: Dr. John Yang (LU Associate Director of Research), Mr. Nasruddeen Al-Awwal (LU Staff Member ) , and Dr. Qingbo Yang (LU Assistant Professor – Analytical Chemistry)

In anticipation of this year’s ARD Research Symposium, Lincoln students worked with advisors on research projects, creating abstracts and posters to coincide with their presentations at the conference. Hundreds of students from these 1890 universities participated this year in the event, which was hosted at the Atlanta Marriott Marquis in Atlanta, Georgia over the course of 4 days (April 2-5). This year's conference theme was " The 1890 Research and Innovation Agenda: Pathways to Build Back Better." Students were able to present their research and listen to fellow scholars’ findings. Each student was placed in a competing category—and three Lincoln University students were recognized for their presentations. Jude Addo-Chidie, Hannah Grogan, and Logan Prenger were all awarded at this prestigious conference.

Jude Addo-Childie (left) stands with his poster presentation and his advisor, Dr. Tunissa Hurriso.

Jude Addo-Chidie is a graduate student at Lincoln University majoring in sustainable agriculture. He is originally from Ghana, and he received his bachelor’s degree from Kwame Nkrumah University of Science and Technology—specializing in crop and soil science.

Jude has been interested in agriculture since high school, stating it is a vital livelihood back in his home country. He worked as a research assistant at the University of Ghana until given the opportunity to study at Lincoln for his master’s degree. While at Lincoln, he has claimed to have “gained lots of experience from his master’s program.” In fact, his ARD presentation is a chapter from his thesis he is working on, which focuses on soil health and management practices such as using cover crops.

“Winter Crops Impacts on Soil Health and Weed Suppression” was the title of his ARD poster presentation, and he placed second in his competing category: "Renewable Energy, Natural Resources, and Environment and Climate Change."

In his presentation, he explained which cover crops benefit Missouri. He also spoke on his analysis on a survey completed by Mid-Missouri farmers, which revealed that many farmers are not adopting the use of cover crops because of its unknown benefits. Cover crops slow erosion, improve soil health, and enhance water availability. They also help control weeds, pests and diseases, while attracting pollinators.

Cover crops have been proven to increase crop yields and add organic matter to soil. However, Jude expressed in his presentation that “many farmers are not adopting this practice because they do not have enough information on the benefits of cover crops, especially since they tend to vary site to site.” This is one of the reasons as to why Jude focused on this project for his presentation and his thesis.

While at Lincoln University, he was able to perform enough research to conclude which cover crops work best in the Mid-Missouri area. Results showed winter rye, hairy vetch, radish, and white and red clover worked best in that area. With the help of Lincoln University and his advisor, Dr. Tunsisa Hurisso, Jude was able to help local farmers with this information.

Student Hannah Grogan receives first place award for her category of "Family, Youth, Community, and Economical Development" poster presentation.

Hannah Grogan is another Lincoln University student who was recognized at the ARD Research Symposium. She is a graduating senior, majoring in agricultural science with an emphasis in animal science and a minor in chemistry. She is from Jonesboro, Arkansas and chose Lincoln University after attending the institution’s Ag Discovery, a two-week long event where prospective students stay in the dorms, tour campus, meet faculty, and travel around Missouri to see how Lincoln connects with farmers.

During this time on campus, Hannah was able to receive information on scholarships, leading her to become one of the USDA’s 1890 scholars, which helped fund her way through college at Lincoln University. When asked why she is so passionate about agriculture, she claims its versatile nature, quoting the motivational speaker, Brenda Schoepp, who said: “My grandfather used to say that once in your life you need a doctor, a lawyer, a policeman and a preacher, but every day—three times a day—you need a farmer.”

Hannah placed first in her category of Family, Youth, Community, and Economical Development with her poster presentation, “Survey by Agriculture Advisor of an FFA Virtual CDE Judging Contest and In-Person Contest.” CDE stands for Career Development Event, which is implemented into Missouri high schools, as well as the curriculum surrounding it based on different areas: farm business management, dairy cattle, livestock, poultry, entomology, agronomy, floriculture, nursery and landscaping.

Usually CDE contests are held in person; however, since COVID, virtual contests have been put into place, as well. Hannah analyzed the feedback on surveys that her advisor, Amy Bax (LU Extension Associate), created to see what others thought on the different experiences of in-person versus virtual contests.

The surveys were distributed during an FFA CDE contest, which happened to be Lincoln University’s 40th year of hosting that event. Normal attendance is around 850 people, with about 1200 online participants. However, Hannah explained some of the negatives to virtual CDE contests—for instance, horse judging is difficult, along with taste tests for dairy products such as milk and butter.

Competitions within floriculture are also problematic because one cannot see or touch actual plants when in a virtual setting. Even with 62% of participants stating that there was no difference between in-person and virtual contests, Hannah explained how that may not honestly be the case.

LU Student Logan Prenger

Logan Prenger was also awarded at the conference, as a first-year undergraduate majoring in plant and soil science. He holds an associate’s degree in wind energy technology, working as a wind turbine technician before enrolling into Lincoln University as an 1890 scholar.

Logan initially just wanted to major in something in the STEM field that he thought would be helpful. However, after working in the College of Agriculture and with local farmers, he has become excited about his research on how to help with cost and day-by-day overhead reduction for local communities. He stated that it is not too profitable to be a small farmer, so being able to do this research to help with that, makes him feel good about the work he is doing.

“Feed Formulations for Batch Cultures of the Water Flea, Dalphnia Magna,” was the title of his poster presentation that he placed first in for the category Animal Health and Animal Products. Logan took on this initiative because his advisor, Dr. James Wetzel, wanted to help a local hatchery/aquaculture facility —Osage Catfisheries.

Logan said, “We gave them the technology and resources, along with a lot of the daphnia magna. Then, we were given broodstock for raising new populations of a certain fish.” He further stated that his presentation went well due to Dr. Wetzel’s hands-off approach, allowing him to do a lot of the work on his own, which came in handy when he was being questioned on his research by the judges. He was able to present information on feed formulations and his experiences more easily due to his heavy involvement on the project.

The feed formulation for this trial was a 3:1 mixture of alfalfa and yeast. Many fellow scholars were also presenting on feed preferences for chickens and aquaculture, so he was able to learn about what other researchers were doing, making the ARD Research Symposium an invaluable experience as a first-year freshman.

Several Lincoln students claimed that it was a fun experience to meet people with the same interests, as well, making it a true learning and networking experience. Many also expressed how much they enjoyed Atlanta, Georgia and being able to travel there with their peers. Lincoln University funded the trip for students to gain this opportunity that they will remember for a lifetime.

All three students mentioned how amazing the symposium experience was, giving thanks to Lincoln University and ARD for providing such a rewarding opportunity. Students were able to share their research, while learning about what other schools are working on, as well. Hannah Grogan reflected that “it was exciting because I got to see other students’ research. We were able to sit in and listen to research from Florida, Oklahoma, West Virginia, and more, getting to see agriculture in all these different places. It was insightful because it was different from what we were used to in Missouri—different soil, air, environment overall.”

LU faculty and staff pose with students to celebrate their great success!

Quinoa Greens Take Center Stage at LU Carver Farm

One of the key events in LU Cooperative Extension and its training staff is “field day for farmers.” One recent event occurred on May 13, with the production of Spring Small Ruminant Field Day at the Lincoln University George Washington Carver Farm.

The all-day event was filled with lots of talks and discussions on various related topics. The event also included demonstrations with live farm animals. Twenty-two farmers participated, of which 47% were women and 53% were men. The ages ranged from 76% (18 to 64), 18% (65+) and 6% (under 18). Twelve were from different counties and states.

Dr. Homero Salinas (LU Extension State Specialist) and Ms. Amy Bax (LU Extension Associate) organized the Small Ruminant Field Day at Carver Farm. Ms. Yvonne Matthews (LUCE Associate Administrator) opened the event by welcoming and with a remembrance of the starting of Carver Farm. She also encouraged the farmers to take advantage of each speaker's experience.

The program’s agenda covered the following topics:

Fencing and Water Distribution by Mr. John Turner

Pasture Management for Multispecies by Dr. Bruce Shanks

Decreasing Input Cost/ Increasing Pasture Management by Mr. Wes Tucker, MU Extension

Managing Warm Season Annuals by Mr. Chris Boeckmann

Prevention and Management by Ms. Linda Coffey, NCAT ATTRA

The following field demonstrations were performed with the assistance of LU Teams Coordinator Mr. E. Grosse:

Grazing Demo by Mr. John Turner

FAMACHA training by Dr. Homero Salinas and Mr. Troy Wieberg

Fecal Egg Count Demo by Ms. Susan Jaster and Ms. Amy Bax

Quinoa Leafy Greens Research and Production at LU Campus Greenhouse

Maturing quinoa leafy greens at LU campus greenhouse.

LU President John B. Moseley and LU Dean of Agriculture, Environmental and Human Sciences Dr. Majed El-Dweik visited the quinoa leafy greens production in the high tunnel at LU Carver Farm on May 12th and were delighted to see the growth of the greens.

A high tunnel, sometimes referred to as a hoop house, is an unheated, partially enclosed greenhouse-like structure covered with various types of thermoplastics that allows for sufficient sunlight and protection against UV rays, wind, excessive rainfall, and cold weather. Using this method allows for an extended growing season, with more flexibility to meet local market needs.

LU President John B. Moseley and LU Dean of Agriculture receive update on quinoa progress from Dr. Safiullah Pathan, the project's PI.

Dr. Safiullah Pathan, Associate Professor of Crop Science, provided an overview and recent updates on production and LU’s promotion of quinoa leafy greens as a nutrient-rich value-added specialty vegetable in USA. Quinoa leafy greens, like quinoa grains, are rich in nutrients and health promoting properties. These properties include antimicrobial, anticancer, antidiabetic, antiobesity, antioxidant and overall reduction of certain health diseases.

On May 17, the quinoa research team at LU organized a high tunnel event attended by 25 community attendees who registered for a “field day” at Carver Farm. Participants planted three quinoa varieties on three different dates at an interval of 10 days. Each were provided with a bundle of leafy greens to taste test the following day.

Dr. Pathan is currently the Principal Investigator (PI) on two USDA-NIFA funded projects on production and promotion of both quinoa grains and greens. To the best of the university’s knowledge, Lincoln is the only institution conducting research on quinoa greens and leads the Midwest in research on production and promotion of quinoa grains.

Lincoln University Awarded NASA MUREP PSI Grant

Lincoln University was recently awarded a NASA MUREP PSI (Minority University Research and Education Project – Pre-College Summer Institute) grant to promote excitement about STEM education among minority, underserved, and underprivileged students. Lincoln University, a historically black American university, proposed to provide opportunities for underrepresented minority students to explore the water cycle, nutrient cycle, abiotic stress, emerging pests, water quality, digital agriculture technology, predictive modeling, and machine learning.

Through experiential learning, students will gain an understanding of the impacts of climate change on the agricultural production system and the ecosystem in general. STEM professionals and scientists from different fields will engage students to appreciate critical environmental challenges that will need STEM professionals.

Dr. Sougata Bardhan

The proposal is led by Dr. Sougata Bardhan, Assistant Professor of Natural Resource Management in the College of Agriculture, Environment, and Human Sciences. Dr. Bardhan’s research emphasizes developing an agroforestry program including forest farming, alley cropping, and silvopasture practices at Lincoln University. Additionally, Dr. Bardhan also conducts research on microbial ecology and nutrient management in various land-use systems to evaluate the impact of human interference on the ecosystem and environment.

Extension Outreach Centers Create New Learning Experiences for Youth and Adults

Exploring Water Safety!

The “WaterBuds” class ended successfully in Pemiscot County during the spring season. Young children became familiar with the water and learned basic skills like floating, kicking, and blowing bubbles. WaterBuds took place at the Diane Sayre Recreation Center and was a partnership between LU Cooperative Extension Area Educator Mariann Wright and the Caruthersville Parents As Teachers Association.

The goal of the class was for all participants to improve their swimming skills, gain more confidence, and observe safety rules while in and around water.

Classes designed for both parents and their young children are a wonderful way to introduce good water safety habits. It also helps to ensure the start of building swim readiness skills.

WaterBuds required each child to have an adult with them in the water. In addition to providing a joint learning experience, this also allowed parents to see the impact of the class.

LUCE Area Educator Mariann Wright introduces a participant to the water.
One WaterBuds participant demonstrates water skills as she glides toward her mother.
Blowing bubbles is a fun part of dispelling fear of the water.
Changing positions in the water and learning to use legs to kick are skills learned in WaterBuds.

At the close of WaterBuds, each of the participants received an “I Can” award and photo book documenting their progress over the five-session class.

All adults in the program gave an A+ to the class and the WaterBuds experience!

Celebrating Pollinators!

4-H Area Educator and Assistant to the Southeast Regional Coordinator Mariann Wright was pleased to be a part of “Community Pollinator Habitat Planting” which took place in Kennett, Missouri on Saturday, April 30.

Participating youth eager to start the project!

The event was organized by the Missouri Department of Conservation and hosted by St. John AME Church and the Kennett Community Garden.

Youth learn the value of volunteerism by working with parents and LU staff.

During this community event, youth rotated through four learning stations. They included the following activities:

  • Pollinator virtual sundae which taught youth the connection between pollination and the foods we eat.
  • Bee presentation that focused on the habitat and behavior of bees.
  • Seed bomb station where participants made their own seed bomb.
  • Lesson on butterflies that highlighted the monarch and its migration patterns.

The event concluded with the planting of an acre of wildflowers in the community garden. The wildflowers will serve as a pollinator habitat for the garden’s upcoming growing season.

Ecology Exposure Within Youth Summer Programs

Learning Relationships Between Living Things

Fourth graders at South Elementary School in Kennett, Missouri, learned all about the relationship between living things and their environments during the annual Ecology Day in May. 4-H Area Educator Mariann Wright led one of the seven stations and taught students about the relationship bees have to their hive, plant life, and humans.

At her station, Ms. Wright led a hands-on activity, and Program Assistant Dawn Jordan demonstrated how bees contribute to plant pollination. Following the activity, students then had the opportunity to sample different types of honey in a honey taste test.

Mariann Wrights explains the visual difference between honey samples.

The taste test was executed in a bracket format where two types of honey were pitted against another two. The winners from Round One then entered into the Championship Round where one would come out on top. The youth sampled clover honey, berry honey, wildflower honey, and orange blossom honey. Each child was given honey-money tokens to use during the taste test voting process.

Youth discover distinct taste of various types of honey.

The youth shared that they enjoyed the hands-on participation. Each class stated that the “bee station” was their favorite of the day!

Production, intake, and feeding behavior of dairy goats fed alfalfa via grazing and cassava

ABSTRACT - This study examined the replacement of maize and soybean meal with cassava chips and alfalfa grazing, respectively. Twelve lactating Anglo-Nubian goats were kept on a Panicum maximum cv. Tobiatã pasture. The experiment was laid out in a Latin square design in which the following diets were tested: ground maize + soybean meal, cassava chips + soybean meal, ground maize + alfalfa grazing, and cassava chips + alfalfa grazing. The evaluated variables were feed intake, daily weight gain, milk yield and composition, and feeding behavior of the goats as well as production costs. Cassava chips and grazed alfalfa influenced the intakes of dry matter, crude protein, neutral detergent fiber, and total digestible nutrients. However, milk yield, body weight, and body score did not change. There was no diet effect on the proportions of protein, solids-not-fat, somatic cell count, or urea nitrogen in the milk. Treatments influenced the levels of fat, lactose, and total solids in milk, with the highest fat levels achieved with diets containing alfalfa. Grazing, rumination, and idle times and time spent interacting with other goats were not influenced by diets. The evaluated feedstuffs improved feed efficiency and reduced production costs. Therefore, cassava chips and alfalfa can replace certain ingredients without impairing the production performance of goats, but rather improving the profit of the producer.

Muscle fiber area, collagen, and fatty acid profile of goat meat

ABSTRACT - The present study was conducted to evaluate the effect of breed group, slaughter weight, and sex on the muscle fiber area, collagen percentage, and fatty acid profile of goat kid meat. A total of 74 animals (Alpine; ½ Boer + ½ Alpine; ½ Nubian + ½ Alpine; ¾ Boer + ¼ Alpine; and three-cross [¼ Boer + ¼ Alpine + ¼ Nubian]) were used. One animal was selected per slaughter weight, sex, and breed group to evaluate the fatty acid profile. One-third of the animals was slaughtered upon reaching 25, 30, and 35 kg. The experimental design was completely randomized and Tukey’s test was used to compare the means. There was no difference for muscle fiber area or collagen percentage between the tested parameters, indicating similar texture of the meat from the evaluated animals. Sex influenced the C14:0, C16:0, C16:1, C20:3n3, C20:5n3, and omega-3 fatty acids, whereas breed group influenced the levels of C18:2n6c, C20:0, C24:1, and CLA cis. Slaughter weight did not affect the fatty acid profile, but the sex × slaughter weight interaction influenced the levels of C18:0, unsaturated fatty acids, and the polyunsaturated/saturated fatty acid ratio. Male and heavier animals produce the best meat in terms of nutrition.

Status quo of genetic improvement in local goats: a review

ABSTRACT - This review aims to summarize and synthesize the fragmented information available on the genetic improvement of local goats (criollo, indigenous, native) on the American and other continents, where populations with these goats have an important role in food security and the economy of rural communities, as well as in conservation of biodiversity and productivity improvement. Topics such as the current state of goat production globally, conservation programs, resistance to parasites and diseases, use of phenotypical characteristics and genomic information, and molecular markers for genetic improvement are addressed. The main challenges, opportunities, and limitations described in recent literature concerning local goats in the immediate future are discussed.
