harvest was covered with weeds, and tomato plants were very<br />

small. Harvesting in this area was very t1me consuming, compared<br />

with either of the treated ~eas. '<br />

Total seasonal yields, both iq ~bersand pounds of<br />

tomatoes for each variety, are s\UIlnIarized1n Table 4. All varieties<br />

except Roma produced a grea~er totalwe1ght of fruit in the<br />

treated than in the untreated. Only in the case of Roma and<br />

Homestead.61 were there slightly more fruit in the untreated than<br />

the treated. This implies that Solan did not.have an inhibiting<br />

effect on the set of fruit!<br />

The varieties Hom~stead 24, H J.370,Manalucie, val~~t<br />

and Rutgers California produeed somewhat fewer pounds of tomatoes<br />

at the 8 pound rate than at the 4 pound rate. . The fact that the<br />

other varieties produced eq4al or greater .weights of tomatoes at<br />

the 4 pound rate suggests that one is working with a good ~gin<br />

of safety when suggesting the lower rate asa commercialpract1ce.<br />

~ Seeded Tomatoes, Exper1mentNo. 1, 12§Q<br />

Seeds of the varieties Fireball and Red Jacket were<br />

planted and Solan at the rate of 2, 4 and 6 pounds per acre was<br />

applied to the seeded areas on the day of, and 2, 5 and 7 day~<br />

after planting. Each treatment comprised a single row 10 feet<br />

long and was replicated three times.<br />

Uhder conditions of the tel;lt, ~'stage of gr-owth" of the<br />

tomato plants varied from "not,germinated<br />

ll<br />

·to Ilbreaking the·<br />

ground ll • <strong>Weed</strong>s at the various test intervals varied from "not<br />

germinated ll to one inch high: Results of stand counts and percent<br />

of weed control, as taken some two weeks after the last<br />

t'eatment, are ,given in Table 5.<br />

Treatments applied on the day of seeding had no eft~t<br />

on germination of either variety. Control or weeds, while partial,<br />

was far from satisfactory" Delaying the tneatment even 2 days<br />

did not reduce crop stands, a~d resulted in appreciable controa.<br />

It was noted that some weeds had germinated at the time of treatment.<br />

When applications were made 5 days after seeding, crop<br />

plants had germinated, but had, not broken the soil. <strong>Weed</strong>s had~<br />

germinated considerably ,but were less than one inch in height.,<br />

Under these conditions the stand of Fireball was reduced when<br />

Solan was applied at 4 and 6 Pounds per acre, and the variety<br />

Red Jacket was reduced only when treated at the 6 pound level.'<br />

Control of broadleaved weed species was good, but grass control<br />

was marginal.<br />

The remaining plots were treated one week after planting,<br />

at Which time weeds were one inch tal]:., and tomatoes were<br />

breaking the ground. There was a significant reduction in crop<br />
