Ethylene chlorhydrin for sprouting sweetpotatoes
Because they give poor sprouting, several new sweetpotato varieties
with excellent flavor have been neglected by farmers. Under a technique
developed cooperatively by the California and Texas stations,
ethylene chlorhydrin stimulated sprouting better than any other
method (including chemicals and heat treatment) on nearly all varieties
Harvesting burley tobacco for best returns
The optimum time for harvesting burley tobacco, based on crop
value, the Tennessee station (coop. USDA) finds, is 25 days after
topping. In their experiments tobacco was harvested beginning about
August 15-7, 13, 19, 25, 31, 37, and 43 days after topping. Improvement
in grade quality and yield resulted in an increase in crop value
of about $300 per acre from the first to fourth harvest, and a decline
of $300 from the fourth to the seventh harvest. Appreciable losses
have resulted from either cutting the crop while tobacco is too green
or delaying harvest unduly. Growers would receive maximum returns
per acre if they began early enough, as with one or more primings,
to permit harvest of much of the crop at the optimum stage,
instead of beginning at the optimum stage and completing the harvest
when tobacco is overmature. Results show that, irrespective of harvest
date, the lower leaves on the plants have physical properties and
chemical composition presently desired for use in cigarette manufacture.
Certain desirable chemical changes were found to occur as
leaves at different positions on the stalk reached the optimum stage
Plant bed fertilizers
Fertilizers should be applied to tobacco plant beds at rates consistent
with the nutritional needs of the plants; excesses detrimental to seed
germination or that will produce weak, overly succulent plants should
be avoided. Plant bed studies with burley on Cumberland, Dunmore,
and Nolichucky silt loams by the Tennessee station (coop.
USDA) indicated that 2 to 1 pound per square yard of 3-9-6
fertilizer, or its equivalent, with the nitrogen not entirely in the
nitrate form, is adequate for production of tobacco plants in the area
concerned (Greenville). When applied at time of seeding, ammonium
nitrate, ammonium sulfate, and a mixture of nitrogen sources
were about equally effective in producing early plants.
Fertilization and the control of weeds in tobacco plant beds can
be carried out in one operation as the result of research by the
North Carolina station. The one-treatment mixture developed contains
the essential plant nutrients for seedlings, plus herbicides for
control of common weeds infesting tobacco beds. Offered as a special
plant bed (16-6-2) fertilizer by dealers, the mixture is applied at
the rate of 3 pounds per square yard in the fall, 60 to 90 days before
seeding the beds.
