 RESULTS OF THE KENTUCKY SORGO ·
PERFORMANCE TEST - 1960
By J. F. Shane
During the 1960 season 11 sorgo varieties, were grown at the Robinson Agricultural
Experiment Substation at Quicksand. Ky. The test was laid out in a randomized—block
design of five replications. Three—row plots, approximately 1/200 acre in size, were  
used. In general, the season was quite favorable for plant growth.
Stalk samples of each of the 11 varieties were sent to the U. S. Department of Agri-
culture, Sugar Crops Field Station, Meridian, Miss. , for milling, juice analysis and
sirup processing.
The amount of juice that can be extracted from the stalks and the sugar content of J
the juice are two important characteristics of sirup varieties. The percentage of soluble
solids in the juice is determined by using a Brix spindle or hydrometer. Most of the
soluble solids are sugars of some kind.
Sirup of high quality should reach a finishing temperature of at least 1O8OC(or 2260F).
A standard finishing temperature of 110OC(or 230OF) was used for sorgo sirup in the tests.
Difficulty in producing an acceptable sirup might be encountered if this temperature cannot
be reached. The sirup is taken off when the foam begins to roll and temperature is more
or less static Raising the temperature from this point would tend to scorch the sirup and
give a darker color Only two of the varieties in the 1960 test boiled down to the finishing
temperature desired; therefore, temperatures which were reached are given for each of
the varieties. Calculated yields are indicated by footnotes.
Data for the 1960 test are presented in Table 1 and for the five—year period 1956-60
in Table 2.
Results obtained from a large number of experiments or for a number of years are
a bottcr estimate of performance than are the results from any one test or year; therefore,
most attention should be given to the information contained in Table 2.
