The Results Are In

Several crops were included in variety trials again this year. Watermelons and muskmelons were grown at the Graves plots and sweet corn, tomatoes, peppers and watermelons were grown at the St. Joseph plots.

Watermelon Varieties

At Graves 19 seeded varieties were direct seeded and 19 seedless varieties were transplanted on May 17. The field was tilled and treated with Diazinon to control cucumber and squash bugs. Treflan was used for weed control and the field was hoed and tilled three times.

Of the seeded varieties, ‘Carnival’ produced the most melons and the most total weight. ‘SF 800’ had the highest Brix reading (an indication of sugar content) while ‘SF 810’ had the heaviest melon. In the seedless varieties, ‘Chiffon’ had the most melons while ‘Freedom’ produced the most total weight and heaviest melon. Five varieties had the highest Brix readings. Seedless melons had higher average Brix readings than seeded ones, indicating higher sugar content.

Melons

Muskmelon Varieties

Muskmelons were also direct seeded on May 17. They were hoed and tilled to control weeds and sprayed twice with Diazinon to control cucumber beetles.

‘Athena’ produced the most melons and had the highest total weight. The heaviest melons were “RML 8726’. A honey dew melon, ‘Sweet Dream’, had the highest Brix reading but did not rate well in an unofficial taste test. High sugar content does not always produce good taste.

Sweet Corn Varieties

Sweet cornForty-four sweet corn varieties were direct seeded on May 10. All were of the sugar enhanced (s.e.) type. Two rows of each variety were planted. The field was treated with Bicep II for weed control. The field was treated with 100 pounds of urea fertilizer when plants were about a foot tall. Diazinon was applied to the corn silks to decrease corn earworm damage. The number of ears, weight of ears, and ear length were determined for each variety. Very little smut was observed this year and earworm damage was minimal. Heavy rain and wind damaged the crop on July 12 but most of the plants recovered.

‘BC 4806’ produced the most ears while ‘Luscious’ and ‘Sweet Select’ had the heaviest ears. In general, later varieties had taller stalks and longer ears.

Data has been tabulated and is available from the Buchanan County Extension Office, 4125 Mitchell Avenue, St Joseph, MO 64507, 816/279-1691. More information on variety trial results is available on the Agriculture Electronic Bulletin Board (AgEBB) website at http://agebb.missouri.edu/.

Tomato Varieties

TomatoTomato varieties planted were a duplicate of a trial at Kansas State University. Fifteen varieties were transplanted into a randomized block design on May 10. Twelve plants of each variety were used in 3 plots. The plants were placed in wire cages when they began to bloom. Treflan was applied pre-plant for weed control. About 2 ounces of urea were added to each plant on June 12. There was a large infestation of bindweed and morning glory plants that hindered the plant yield.

The spring was wet and cool and the plants developed a stem or root rot. Many of them did not survive. As the fruit developed, frequent rains caused fruit cracking and enhanced the invasion of early blight. Treatment with fungicides did not seem to help and the yield was greatly reduced. Few number one tomatoes were harvested.

‘Mt Spring’ and ‘Sunpride’ were the top yielding varieties for total weight. Fruit size for all varieties was medium to small due to adverse weather conditions. ‘Mt Belle’, a cherry tomato, and ‘Sweet Olive’, a grape tomato, were very prolific in terms of fruit numbers. The cherry tomato was much larger than the grape tomato and was higher in total yield. They both had some fruit cracking. They also ripened unevenly and picking the fruit required much labor.

Pepper VarietiesPeppers

Thirteen varieties of pepper were transplanted into the field on June 13. Diazinon and Benlate were used to suppress insect and disease problems. The cool wet weather enhanced root and stem rot and some plants were lost. A very hot July did not allow fruit to set on most of the plants. Only the jalapeno peppers set fruit. ‘Xena’ and ‘Hot Drying Ristar’ were the two varieties that had the most fruit.
