Florida 20 averaged higher in No. 1 string than any of the check varieties over the
 two-year period, exceeding Florida 15 by 5 percent, No. 63 by 8 percent and Dixie Shade by
 11 percent. It also averaged 2 percent fewer broken leaves (XL-1), reflecting the slightly
 smaller and flatter leaf which allows easier handling. These percentages for broken leaves
 are higher than would be expected in a commercial crop because of the amount of handling
 required in experimental work. Averages in the off-color grades (LC-1 and LC-2), medium
 and filler grades for Florida 20 are about the same as for the other three varieties. Grade
 index, which takes into account all commercial grades into which the tobacco was separated,
 was highest for Florida 20. Crop index was exceeded only by the value of Florida 15, which
 is caused by the higher yield of the latter variety.

 Results of two commercial trials are given in Table 3. Florida 20 produced a high
 percentage of the No. 1 string grade, with only small amounts in the less desirable grades.
 The percentage of broken leaves (XL-1) was very low in both locations.

 PRODUCTION SUGGESTIONS

 General production practices for Florida 20 are similar to those for other cigar-wrapper
 tobacco varieties now being grown. Attention to the following suggestions should aid in the
 production of a more successful crop, however.

 FERTILIZATION.-Do not use excessive amounts of fertilizer, since this can be a cause of
poor quality regardless of the variety grown. Follow fertilizer recommendations made on
the basis of a soil analysis.

 BLUE MOLD.-Recommended fungicides should be applied both in plant bed and shade to
control blue mold. Fungicides are also effective in preventing damage from leaf spotting
organisms.

 IRRIGATION.-Florida 20 should be irrigated as needed with moderate amounts of water.
Even though the variety had almost no fleck in 1966, care should be taken not to irrigate
excessively when there is a forecast for the ozone concentration to increase.

 PRIMING.-The interval between transplanting and the first priming should be about 50
days. Sufficient time should be allowed between subsequent primings for the leaves to
mature properly. No more than four leaves per week should be primed.

 CURING.-Florida 20 was developed using a slow curing technique; therefore, best results
should be obtained when such a procedure is followed. Curing temperatures should not be
allowed to go above 1000F, unless the occurrence of barn rot makes an increase necessary to
stop this condition.

 LEAF WILT.-Even when soil moisture is adequate, occasional plants may be seen with a
single leaf near the bud in a wilted condition. This should be a problem only when the
relative humidity is low and rapid drying conditions are present. These leaves may recover
completely or may partially recover leaving small areas of dead tissue between the veins.
In any event, loss from this condition is negligible.

 SEED DISTRIBUTION

 Seed are available from the Florida Foundation Seed Producers, Inc. It is recommended
that the grower limit his acreage of Florida 20 until experience is gained in producing this
new variety. This will provide the opportunity to observe it further under different
growing conditions and establish its acceptance by the trade.
