Hosted by Kim Todd, the Backyard Farmer show is dedicated to helping find solutions to lawn and garden questions. Every year from spring to fall, a panel of experts, featuring faculty members from the Department of Agronomy and Horticulture, deals with topics from insect pests and disease, turf, and fruits and vegetables, as well as landscape design and general horticulture topics.

The Nebraska Master Gardener program extends the outreach of the University of Nebraska-Lincoln by providing volunteers with research-based horticulture education, which prepares them to share their knowledge with the citizens of the state. Master Gardener volunteers are trained by Nebraska Extension faculty and staff. Terri James is the Nebraska Extension Master Gardener Coordinator.

The PAT lab’s research focuses on advancing precision pesticide application technologies to improve decision-making, optimize pesticide use, and enhance crop yields while minimizing environmental impacts. This includes investigating various integrated pest management strategies to address challenges related to weeds, insects, and diseases in row and specialty crops. The evaluation of pesticide application technologies developed worldwide, and their integration into existing cropping systems is critical to this work. Research emphasizes a comprehensive approach to understanding how to deploy these technologies effectively and sustainably.

The lab's extension efforts aim to enhance agricultural practices through education on emerging pest management technologies. These initiatives emphasize adopting advanced methods to improve the resilience and sustainability of cropping systems. Educational outreach includes organizing workshops, seminars, and hands-on training sessions for producers and developing accessible content on pesticides' safe and effective use. Active engagement with diverse stakeholders, including farmers, government agencies, and the pesticide industry, ensures the alignment of these programs with their needs and facilitates meaningful impact assessment.

Research, teaching and Extension programs in range, pasture and forage sciences at the University of Nebraska are committed to addressing the conservation and utilization of rangeland and forage resources. Nebraska’s rangelands provide numerous ecosystem services, including wildlife habitat, soil protection from wind and water erosion, rainwater filtration, underground aquifer recharge, recreational opportunities, and aesthetically pleasing landscapes. They also serve as a valuable forage resource for livestock producers, contributing approximately $12 billion annually to Nebraska's economy through the cattle industry.

The University of Nebraska Testing Ag Performance Solutions (UNL-TAPS) program was developed by the University of Nebraska-Lincoln's research and extension specialists and educators. It advances agricultural management skills and knowledge through competition. UNL-TAPS serves as both a growing-season-long farming contest and a research framework, designed to uncover how producers’ management decisions drive profitability and input-use efficiency.

This interactive program is centered around real-world farm management competitions where innovation takes the spotlight. Participants, including UNL scientists, extension professionals, producers, industry leaders, agriculture students, and government officials, compete to showcase their skills. The competition awards those who achieve the "most profitable," "most input-use efficient," and "highest grain yield" outcomes.

In a low-risk environment, competitors can experiment with a wide array of cutting-edge technology to enhance their decision-making and management skills. This includes satellite and drone imagery, soil moisture and plant sensors, as well as data from local weather stations. These tools provide valuable insights, allowing participants to make informed choices and improve their agricultural practices. At the end of the season, participants gain access to a comprehensive dataset, offering valuable insights to refine their practices.
