HORTICULTURAL TRIALS WITH BUSH SNAP BEANS, SPRING 1961
V. L. Guzman _
These trials were carried out in cooperation with Dr. J. C. Hoffman,
Chairman of the Southern Cooperative Vegetable Trials. Thirteen varieties
were planted for the observational and nine for the replicated trials.
Location and soil type.
The experiments were carried out at W. G. Hull Farm, Pahokee, on a soil
classified as Okeechobee muck, but this particular piece of land contains a
large amount of sand and at planting time was very dry. Therefore germination
in some places(which may have been slightly higher ground) was delayed several
days, resulting in uneven maturity. This condition brought about three pick-
ings of the crop instead of two.
Field plot technique.
Randomized blocks with four replications were used. Plots were single
rows 25 feet long and 2.66 feet apart, with 20 feet actual harvest row. For
the observational trials single unreplicated rows were employed.
The experimental field had been cropped to beans and sweet corn for the
past several years. The soil analysis showed a pH of 5.2, 6 pounds per acre
of phosphorus and 10 of potassium. A 0-14-5 fertilizer with 0.50 of MnO was
applied in bands at seeding time in the amount of 300 pounds/A.
Planting and harvesting.
Two hundred seeds per variety were distributed in 25 foot rows and planted
1 inch deep in the bottom of a shallow furrow. Both observational and re-
plicated trials were seeded March 4, 1961. Harvest began April 26 and the
last picking May 6.
Weeds, diseases and insect control.
Weeds were controlled by the application of 3 pounds of Vegadex per acre
as pre-emergence treatment, two machine cultivations and one handweeding. Cut-
worms were controlled with poison bait. No other measures of control Vere
necessary, since no disease or serious insect damage was noticeable ~~ it
incidence of rust was low. Rust reading a few days after the 1 ~ivest
failed to show clean cut cases of rust pustulas. Very little r fell during,
the growing of this crop, and although in no case wilting of t ants was
observed, the surface few inches of soil were dust ry.Root kU 4
incidence was noticeable in all varieties. Under these condit p, Harveste'r
in particular and other varieties performed quite well except ~rlenderwhite,
which never attained normal vigorous growth.

Table 1 and 2 give the tabulated data obtained.
Table 1 gives the comparative value of the varieties in the replicated
trials. Varieties were ranked according to their yielding ability. The
analysis of the yield data indicate that varieties 16-Harvester and 29-
Valentine type 950 are superior in yield to 15-Wade (check). Entry 22-
B3370 was also a good-yielding line. Extender produced significantly lower
yields than the check. The most attractive bean for the fresh market was
Harvester; however, this variety seems to become over mature rapidly and should
be picked before it reaches market maturity. Line 20-Valentine type 950 is a
good high yielding bean, but its appearance is not as good as that of Res.
Asgrow. Black Valentine. Best percentage of first and second pickings were
obtained with the two flat varieties Valentine type 950, Res. Asgrow Black
Valentine (20-14) and with Extender (17).
Table 2 gives the performance of the varieties or breeding observational
lines. The highest yielding varieties were: 9-B3489, 7-2910-3, 8-B3482 and

Source of Seed: All entries were sent from the Southeastern Vegetable Breeding
Laboratory. Dr. J. C. Hoffman.
Days to Maturity: Number of days from planting to the first picking.
Rust Rating: Rust (Uromyces phaseoli typical Arth.) 0 = no observed lesions to
5 = very severe infestation.
Plant Height: Mean height of 10 plants per plot (inches).
Pod Length: Mean of 25 randomly selected pods (inches).
Pod Color: L = light green, M = medium green as Tendergreen, D = dark green
and W = yellow wax.
Shape of Pods: F = flat, 0 = oval, R = round, H = heart shaped pods.
Pod Roughness: VS = very smooth, S = smooth, SR = slightly rough, VR = very
Pod Uniformity: VU = very uniform, S = satisfactory uniformity, SM = severely
Pod Straightness; S = straight pods, SC = slightly curved pods, VC very
curved pods, C2D = Pods curved in two directions.
Estimated Yields: Pounds per plot extrapolated into estimated bushels per acre
yield (30 lbs.).
Percentage total yield in each of the harvests.
