Fertilizers for flue-cured tobacco
Experiments made by the Florida station on fertilizing flue-cured
tobacco on Norfolk fine sand indicate that the best practice is to
make a side placement 7 to 10 days after transplanting of a 3-8-8
fertilizer containing 2 percent magnesium (1/2 water soluble) and
not over 2 percent chlorine, when high rates are used; reserve part
of the fertilizer for later application in case of leaching of the soil
by rains early in the season; and refrain from growing tobacco immediately
after a legume crop. A nitrogen ratio of one third each
from sodium nitrate, ammonium sulfate, and urea produced highest
yields with good quality. Cottonseed meal, soybean meal, and dried
blood were preferable to many other organic nitrogen carriers. Fertilizer
rate will range from 1,000 to 1,600 pounds per acre, depending
on soil type and organic-matter content, and the number of plants
from 5,000 to 7,000 per acre depending on fertilizer, soil type, and
About 1,400 pounds of 3-10-10 fertilizer per acre was the maximum
rate at which good quality smoking tobacco could be produced with
flue-cured varieties in experiments by the Georgia Coastal Plain Station
(coop. USDA) on Norfolk and Tifton sandy loams. Increasing
the fertilizer from 1,000 pounds to 1,400 pounds resulted in a gain
of $115 in acre value; and increasing it from 1,400 to 1,800 pounds
gave a further increase of only $28. Application of additional fertilizer
gave greatest increase in returns when moisture was not a
limiting factor. As compared with low rate of application, ripening
was delayed about one week when the high rate fertilizer was applied.
Fertilizer placement for cigar tobacco
Placing half of the fertilizer for Havana Seed tobacco on the
plow sole and harrowing the remainder into the upper soil gave higher
yields in Connecticut Agricultural Experiment Station studies than
the usual method of broadcasting all the fertilizer after plowing and
then harrowing it into the upper few inches. The better distribution
under the first method made the plant food available at both deep
root and upper levels. Both methods were superior to broadcasting
before plowing, drilling in bands close to the row, or placing all
the fertilizer on the plow sole.
Quality in Vegetable Crops
Quality and quality control are subjects foremost in the minds of
vegetable crop research workers. Better grading standards, elaborate
refrigerated display cases in large supermarkets, the introduction
of transparent plastic wraps and window bags, even
improvements in color illustrations for canned goods, all have stimulated
greater demands for higher quality vegetables.
The Indiana, New York State, and Ohio stations (coop. USDA),
recognizing the marked importance of canned tomato products, have
been engaged in research that may have considerable effect on the
