 EFFECT OF RATES OF ALAR ON GROWTH AND YIELDS OF CARROTS

 V.L. Guzman


April, 1970


Exp. 582

Objective:


The objective of experiment 582 was to reduce top'growth, thus


 facilitating harvest.

Location: Duda Farm, Belle Glade, Florida.

Soil type: Peaty muck six years under cultivation.

Soil test after fertilization: pH = 7.00; P = 40;,.K= 400 lbs/A.

Design: Randomized blocks with eight replications.


Herbicide: Lorox and mineral spirits.

Seeding date: October 25, 1968.

Alar treatment date: December 20, 1968 SEP 1 1972

Spray rate: Drip point.

Stage at Alar application: 6-9 leaf stade;, g A6S f d,


Weather: 70 degree F; no rainfall; soil"moisture good.

Treatments Alar ppm: 1 = 0; 2 = 1000; 3 = 2000; 4 = 4000.

Harvest date: March 7, 1969.

Harvest plot: 10' x 45" double rows, total area 10' x 45" = 37.5 sq. ft. plot.

Results: There was a reduction in top growth noticeable to the eye two
weeks after application. This reduction appeared to be in proportion to the
concentration of Alar used. However, reduction of top growth had
disappeared at harvest. Yield and quality of the roots are given in Table I.
It was an added bonus to find that yields were increased with Alar.
Single degree of freedom analysis indicated that Alar (rates) significantly
increased yield over the check. There were no significant differences
between the Alar rates, but all the Alar treatments combined resulted
in yield increase over the check. No difference in root quality was
found among the treatments.
