AGRICULTURAL FIBLD NOTES

WAYCROBS, GA. Mr. Fred Voig,: local seedsman, has on his farm near
here a most striking example of the necessity of thorough inoou3ation to ob-
tain a good growth of blue lupine, a winter cover crop that is becoming in-
creasingly popular each year in this locality. In a small field about 4 1/2
acres he sowed the lupine broadcast at the rate cf 75 pounds of seed per eore,
and harrowed the seed in with a tractor-drawn disc harrow, The seeding was
made just prior to the middle of October at which time there was a fair season
in the ground. The soil is of a light sandy type, and as an aid in obtaining
a stand he ran a drag over the field to give a firm seed bedy and he obtained
a very good stand. On about 1 1/2 acres on which blue lupine had been success-
fully grown the previous year he did not inoculate the seed, while on the re-
maining 3 acres he used seed that had boon treated with twice the amount of
innooulaft generally recommended. The lupine that was inoculated has made a
luxuriant growth, is of a uniform height of around four feet, is dark green In
color, and has produced a tromamdous tonnage of green matter to enrich the
soil. Although on the uninoculatod portion of the field the lupine has made
fair growth, the foliage is light green or yellow in color and the plants laok
vigor* The denarkation between the inoculated and uninoculated is most strib.
ing* It is also most interesting to observe numerous snail spots throughout
the uninooulated aroa whore groups of plants shcr the same luxuriant growth
and green color which charactorise the inoculated area. Mr. Voigt explains
this rather unusual sight by the fact that the inoculating baotoria on the
previous years lupine crop were able to survive the sunmrr in those partiu-
lar spots. After four years' otporienoe with blue lupine he is most enthusi-
aatio over the showing it has made on his farm, and believes it is far su-
perior to Austrian Winter Peas and Votch as a winter cover crop* He believes
that some growers have fnilod to obtain satisfactory stands largely because
of improper sooding. He says he has found that the sood should be covered
about 3 inches doep, and with heavy seeding of 60-75 pounds of seed per acre
good stands should bo obtained*
TAMPA, FLA. Raindrops which carry away thousands of tons of die -
solved plant food every year, particularly on southern sandy soil, ab they
trickle down through the ground don't leach nearly as much plant food, when
the soil pH approaches 6*00, it has been found in a test at the Florida aX-
perriont Station. Fertilizers consisting of ammonium nitrate and potassium
Sulfate were applied in solution at high rates to soils in lysimeters (tanks)
where leaohings could be measured. After 18 hours thq wwo leached wath
five- 1/4anoh drenohihgs of distilled water during anei M hourP s 6. Me
Volk, station chemist, says that Norfolk light sand with i IT .ot 3.98 lost
43.5 per cent of the ammonia and 333 per cent of the pPtash applied similar
soil with a pH of 5.46 lost 20.9 and 19.7 per cent of AmonUa and paamshe At
pH 6,30 the losses were 12.8 and 13*7 per qenti at pH 6.85 losses wes 6-9 u I
9*6 per cent Losses following applications of these two plant foods 'were
reduced through liming in other light sandy soila also, ohamist Volk rosoas
meads a pH reading 5.5 and 6.00 for such soils CITUS M&GA3L published bY

JACKSONVI j, fLA. With increasing shortage of expetienoed harvest
labor and the necessiiy of using almost any kind of labor to be had, problems
of tomato growers aje multiplied. In normal times when better trained laber
was available, it was estimated by some well informed shippers and receivers
that 25-30 per cent of the green wrapped tomatoes shipped failed to reach tho
table of the consumer because cf failure to color and ripen properly, which
in turn was attributed largely to picking the fruit too green IExperimenters
with the USDA have found that tomatoes allowed to develop to the green-mature
stage before picking, which iS just *efori color begins to slow, ripen into
satisfactory quality in contrast with poor quality of those picked when im-
mature; they lost less than half as much weight in ripening; fewer of th#m
decayed; the yield per acre was greater; and they had a higher vitamin 0
contents The Department says a green-~ turs tomato is one that is still green
but has reached a stage at which, i hazrvested then, it vll ripen to satis-
factory quality. Furthermadb that there is no single indication of the exact
time to pick, and that gro*erb in Various.locclities with their own types and

indications that are visible just before the first touch of red appears at

ATHENS, GA. After collabo eating with workers at the'Georgia Coastal
Plain Experiment Station, E. C. Westbrook, pr.tbhaion Agronomist, is making reo-
omnendations $p bright leaf tobacco growers in the southern part of the state
who set tobaqte prior to several heavy rains which oaoWurrd in this area. In
his reoonmetidiions Mr. Wostbrook says: 'oSome of the fertililPrs havf been.
leached out by'heavy rains, and if additional fertilizer is not added the yield
of tobacco nay be affected in proportion to the fertilizer loss. However, good
judgmen shouO4 be used in deciding how much additional fertilizer to use*
IMot of the IQ9 has been in the leaching of nitrogeno Additional nitrogen may
be added by se dressing with a complete tobacco fertilizer or by side dress-
iig with nitratr of soda. Where tobacco was set out previous to considerable
heavy rains it~tould be desirable to apply a side dressing at the first culti-
vation of 200 t" 400 pounds per acre of a 3 9 6 fertilizer made especially
for, tobacco, 32 000 pounds or more fertilizer ras used before the tobacco '
was set 200 to )0 pounds side dressing should be sufficient. If less than
1000 pounds were used before setting the tobacco larger nrounts of side dress-
ing can be used profitrnbly. A side dressing of 3 9 6 should give slightly
bitter results than the use of nitrate of soda alone* If farmers are unable
to obtain the regular tobacco fertilizer for side drossinG,the tobacco can be
side dressed with appgroxiiately 50 pounds of nitrate of soda per acre. The
proper dope for each hill of tobacco is a coca-cola bottle top full. More than.
50 pounds of nitrate of soda per acre is likely to eat farmers into serious
trouble. The sane thing applies to the use of too much complete fertilizer as-
a 'side dressing. It is extremely important that, if frrairs use a side dress-
ing of fertilizer on their tobaoeo, they not wa#i longer than the first culti-
vation to apply it. If a side dressing of Asotilser is applied later, there
is danger that the tobacco will be spt a growing a tr a ttime'hen it
should mature and ripen. This may be S good year to produce large yields per
acre of tobacco, but farmers should n*a lose sight of the importance of doing
Aeo things necessary to produce good tobacco. porience and conon sense will
bthho farmers best guides in deciding what are the best things to do."
