TOMATO PERFORMANCE TRIAL, 2000

Richard Greenland, Leonard Besemann and Heidi Eslinger


Results summary

Table 34. Cumulative yields of tomatoes


Tomatoes grow well in southern North Dakota. Yield and quality may be reduced in cool or short growing seasons.

MATERIALS AND METHODS

Soil: Maddock sandy loam; pH=7.4; 1.9% organic matter; soil-P, soil-K, and soil-S were very high.
Previous crop: 1999 - cabbage; 1998 - field corn; 1997 - onion.
Seedbed preparation: Disked on 29 October 1999. Multiweeded (field cultivated) once on April 5. Deep tillage on May 23. Multiweeded three times on May 25; once deep and twice shallow to incorporate herbicides.
Planting: Tomatoes were seeded in the greenhouse on April 3. Plants were hand transplanted to the field on May 26. Rows were spaced 4 feet apart. In-row spacing was 1.5 ft. As it was planted, each plant received one pint of fertilizer solution (1 gal 10-34-0 in 100 gal of water).
Plots: Plots were 17 ft long by 4 ft (one row) wide. Tomatoes were staked on half of each plot.
Fertilizer: On April 4, broadcast 18 lbs N/acre and 20 lbs S/acre as 21-0-0-24. Fertigated 35 lbs of N/acre as 28-0-0 on June 27 and July 14.
Irrigation: Overhead sprinkler irrigation as needed.
Pest control: Weeds were controlled by Tillam (3 qt/acre on May 25) and Treflan (1 pt/acre on May 25) (both applied preplant incorporated), and by hand weeding. We applied Quadris (6 oz/acre on Aug 3) and Kocide (3 lbs/acre on Aug 18 and Aug 31) for blight control.
Harvest: Harvested 8 times from August 6 to September 20.

RESULTS

Sunshine, Sun start, and Tuscany were the earliest tomatoes. No variety clearly yielded more or less than other varieties.
