Performance of Cucumber Cultivars, Plateau Experiment Station, 2001

Charles A. Mullins and A. Brent Smith

 

Interpretative Summary

Yield for all cultivar was lower that expected. >Speedway=, >Greensleeves' and >Indy= were among cultivars that produced the highest marketable yield. All the varieties rated well for color, curvature, and smoothness.

Introduction

Cucumbers are grown on a rather limited acreage in Tennessee. Cucumbers have been identified as a crop that has potential for increased production. The market prefers dark green, straight, and long cucumber fruit. The more popular types of cucumbers grown for fresh market are standard slicing type. Burpless cucumbers have become more popular in recent years, and are milder than the standard slicing cultivars. Pickling type cucumbers are also grown for fresh market. Pickling type cultivars usually are shorter, lighter in color and have smaller seeds and seed cavities than slicing type cultivars. Many of the newer cucumber cultivars have resistance to many diseases. An experiment was conducted at the Plateau Experiment Station at Crossville, TN in 2001 to evaluate performance of 13 cucumber cultivars for fresh market usage.

Materials and Methods

The site was prepared for planting by conventional tillage in late April. Fertilizer was broadcast at 300 lb/A of 15-15-15 before final disking on May28. Four foot wide black plastic mulch was laid on six ft centers on May 9. Plots were direct seeded on May 9. Plot size was one row, 12 ft long and contained 8 plants. Experimental plot design was a randomized complete block with four replications. Row middles were cultivated on June 26. Carbaryl (Sevin XLR) at 1 lb ai/A was applied for insect control on May 17. Esfenvalerate (Asana) was applied for insect control on June 9, June 12, June 23, and July 13. Mancozeb (Dithane DF) at 1.6 lb ai/A and chlorothalonil (Bravo) at 1.5 lb ai/A were applied on June 12, June 23, July 3, and July 11. The cucumber plants were staked with a 54 inch stake driven between each two plants and a string trellis was extended between stakes and was used for support of the cucumber vines.

Nine harvests were made between July 19 and August 10. Yields were recorded by number and weight of marketable, oversize, and cull fruit. Fruit were measured for length and rated for characteristics after each harvest. Three to five fruit were used for these determinations. Ratings were made on a 1 to 10 scale with 1 being the smoothest, straightest, or darkest in appearance.

Results and Discussion

Yield for all cultivar was lower that expected. >Indy= and >Greensleeves= were among those varieties that produced a higher yield in marketable tons per acre (Table 1). >Speedway= and >Greensleeves' and >Indy= were among cultivars that produced the highest number of marketable fruit per acre. >SRQ 2387= led several cultivars in the level of oversize fruit in tons and number per acre. >Speedway= was among cultivars that produced the largest number and greatest weight of cull fruit per acre.

Fruit length was longer for >Sweet Slice= than for all cultivars except >Daytona=, >Lightening= and >Speedway=(Table 2). All the cultivars tested rated well for smoothness, curvature, and color. >Sweet Slice=, a burpless type cultivar, and >Indy= led several cultivars in smoothness. >Indy= and >Dasher II= led several cultivars for curvature. >HMX 8416= and >Indy= were among cultivars rated darkest for fruit color.
