Genomic Selection with Dr. Jianming Yu
Field, Lab, Earth
“Genomic Selection: Essence, Applications, and Prospects” with Dr. Jianming Yu Genomic Selection is a plant breeding innovation that aims to speed plant breeding by using predictions from a training model enabled by genomics and statistics to guide the breeding decisions. With around thirty years of history around this innovation, it was about time to develop a review on it. Enter Dr. Jianming Yu and his team of coauthors. This episode, we skate the surface of a topic that could go down for miles, covering key areas of genomic selection, what it is, how to use it, and where we can aim to...

The Nitrogen Value of Cover Crops with Dr. Guillermo Marcillo
Field, Lab, Earth
“The Nitrogen Value of Cover Crops” with Dr. Guillermo Marcillo. Cover crops are known for their ability to provide economic and ecosystem services to farmers, including, for example, impacting soil nitrogen. But how much nitrogen, exactly, can cover crops add or remove and how do we find out? In this episode, Guillermo joins me to discuss his work collating research data to get to the bottom of cover crop nitrogen replacement values. Tune in to learn: · What a nitrogen replacement value is ...

Compost Organic Matter in a Snap with Dr. David C. Weindorf
Field, Lab, Earth
“Toward sustainable compost use: Prediction of organic matter via smartphone image analysis” with Dr. David C. Weindorf Compost needs to be regularly tested to ensure labels regarding organic matter, nutrients, and more remain accurate. However, getting compost tested is time- and cost-intensive. This episode, Dr. Weindorf joins me to discuss how developing a model to predict organic matter from cell phone pictures might make this process a whole lot easier. Tune in to learn: · Which factors best correlated with organic matter ...

Cover Crops and the Transition to Organic with Nick Boogades
Field, Lab, Earth
“Early impacts of cover crop selection on soil biological parameters during a transition to organic agriculture” with Nick Boodages. Incorporating cover crops is an important step in the transition from conventional to organic growing practices, but in Texas, limited resources can bring complications. In this episode, Nick joins me to discuss his work researching how to help farmers make the leap. Tune in to learn: · What challenges Texan farmers face when hoping to transition to organic agriculture · ...

Soybean Seed Protein Decline with Dr. Anuj Chiluwal
Field, Lab, Earth
“United States soybean seed protein concentrations – current status, challenges and some potential crop management solutions” with Dr. Anuj Chiluwal. Soybeans are a crucial crop in the United States for a variety of uses, including for its use as a protein source in animal feed. However, in recent years, high yield varieties have seen a steady decline in seed protein concentration. In this episode, Anuj joins me to discuss the sources of this decline and some potential strategies to combat it. Tune in to learn: · Why soybean seed protein...

Precision Turfgrass Management with Dr. Briana Wyatt and Dallas Williams
Field, Lab, Earth
“Using electromagnetic induction to inform precision turfgrass management strategies in sand-capped golf course fairways” with Dr. Briana Wyatt and Dallas Williams Golf courses are well known for their beautiful greens, but overusing fertilizer and water to keep them looking pristine can lead to inefficient, expensive, and environmentally damaging waste. Precision turfgrass management can help, but only if we can find the right methods to put it into use. In this episode, Briana and Dallas join me to discuss their research on how electrical conductivity can be used to help determine golf...

The Soil Health Cycle with Dr. Bijesh Maharjan
Field, Lab, Earth
“Soil Health Cycle” with Dr. Bijesh Maharjan Researchers, advisers, and farmers alike know that soil health is important, but taking steps forward in the knowledge of which practices to use and their impacts can be difficult. Enter the soil health cycle, an iterative approach to help track how practices and their implementation take soil health forward. In this episode, Bijesh joins me to discuss his work on the soil health cycle. Tune in to learn: · How the soil health cycle is similar to human health care cycles ...

Speed Breeding to Combat Wheat Disease with Drs. Nidhi Rawat and Vijay Tiwari
Field, Lab, Earth
“Evaluation of speed breeding conditions for accelerating Fusarium head blight and deoxynivalenol screening in wheat” with Nidhi Rawat and Vivek Tiwari. Fusarium head blight (FHB), also known as head scab, is one of the most significant diseases affecting wheat, causing substantial economic losses for farmers in the U.S. and worldwide. While FHB resistant wheat lines have been identified, breeding these traits into desirable cultivars is a time-consuming process that can take decades, with uncertain success. In the U.S., particularly for spring wheat, crossing of wheat lines can...
info_outline“Focusing the GWAS Lens on days to flower using latent variable phenotypes derived from global multienvironment trials” with Sandesh Neupane and Derek Wright.
Lentil, a pivotal pulse crop, is recognized as an important part of food and nutrition security in the world. It has rich sources of important nutrients, is easy to cook, and thrives well on the farm. Due to its rich dietary benefits, lentil has been introduced to North America, especially in Canada. Originating as a warmer climate crop, domesticated in the Middle East and North Africa, and widely adopted in Southeast Asia, lentil can face adaptation issues in the cooler Canadian climate. This struggle directly impacts flowering, pod-bearing, and overall yield. What precisely are the adaptation constraints hindering lentil introduction in North America? How do varying photoperiods and temperatures exert influence on lentil production? Delving deeper, what genes govern the crop's sensitivity to photoperiods and temperatures? In this episode, Sandesh Neupane and Derek Wright share insights into their research on lentil adaptation and how they dissect the genetic mechanisms orchestrating the photoperiod and temperature sensitivity in lentils with multi-location trials and advanced image-based phenotyping. This groundbreaking work promises to contribute significantly to the breeding of well-suited lentil varieties tailored to thrive in North American conditions.

· Lentil and its nutritional value
· Lentil’s history
· The challenges of lentil adaptation in Canada
· How the environment affects lentil growth
