Raspberry harvest in high tunnel

We harvest the in-ground and  in grow bags on Monday, Wednesdays and Fridays. We harvest both good and cull fruit and make sure we remove the cull fruit from the planting in order to manage for Spotted Wing Drosophila. You would be surprised how many SWD flies emerge from one missed berry! After we harvest, the fruit is sorted for ripeness, bagged, weighed and taken to the winery and put in the freezer for use in the distillation program.

Raspberries are harvested and put in buckets tied around the waist with a bungee cord. Callie keeps the ripe and overripe/cull berries in two separate buckets.

Elderberry harvest begins

John Avery, Fruit Grower Adviser, coordinates the elderberry project in collaboration with researchers at MU. Experimental field plots are harvested, put in lugs and labeled. Then they are transported to the stemmer where the berries are removed from the stems, collected and weighed for data.

Berry clusters from the treatments are cut, labeled and collected in lugs.

The base of the plate has holes in it, so when the workers move the clusters around, the berries are vibrated off and fall into a lug underneath the perforated plate.

A conversation on plant breeding and genetics

Logan Duncan, an MSU summer intern who is working on a squash/pumpkin breeding project and Dr. Anson Elliott, Director of the Darr School of Agriculture as well as the State Fruit Experiment Station, talk about plant breeding and genetics out in the field. Logan is a student from Truman State University. Missouri State is collaborating with Truman on plant breeding and genetics student education.

Logan Duncan (left) and Dr. Anson Elliott talk about the squash breeding project. Dr. Elliott was trained in classical genetics and worked in a program on the improvement of rice.

MSU Student intern presentations wrap up the summer program

Our student interns presented information on their work experiences and summer projects this afternoon. Dr. Hwang organized the presentations and Dr. Elliott praised the work of all of the students. “Students working on research that solves key problems is one of the activities at the top of my list. Faculty and staff are using our knowledge and experience  to develop an enlightened generation of scientists, industry professionals, and educators.”

The students stepped out for a group photo with Dr. Elliott, Dr. Hwang, Li Ling Hwan and Susanne Howard.

George Washington Carver Camp visits the experiment station.

Today, Susanne Howard coordinated a tour for the George Washington Carver Camp high school group with faculty and staff from the Springfield campus. Randy Stout took the group on a hay ride, Dr. Martin Kaps presented information on fruit crops and Randy Kreusuer, Kallie Calus and I helped the group harvest raspberries in the high tunnel. Susanne continued on a campus tour with the group. They had a beautiful day for a visit.

The Camp kids enjoyed a hayride.
