Experiments with nitrate of soda on strawberries, E. B. VoonHE
ES (New Jersey Stas. Report for 1891, pp. 141, 142).
Synopsis.-Nitrate of soda was compared with manure on Sharpless strawberries on
2 eighth-acre plats of sandy loam liberally manured two years before with
kainit and phosphate. Nitrate of soda increased the vigor of the plants and the
yield of fruit mainly by enlarging the individual berries. The net increase in
profit was at the rate of about $40 per acre.
Sharpless strawberries were set in 1889 on 2 eighth-acre plats of
sandy loam land, both plats being manured at that time with 1,500
pounds per acre of a mixture of kainit and precipitated phosphate.
In the spring of 1891 nitrate of soda, 200 pounds per acre, was broadcasted
on 1 plat, the other remaining untreated. "' A very decided
difference was noticed in the appearance of the plants on the 2 plats,
those on the untreated plat showing a deeper color, larger leaves, and
a much stronger bloom." The yields of berries were, without nitrate
1.62 quarts per plat, with nitrate 213 quarts per plat.
The gain in yield from the use of nitrate was 51 quarts or 31 per cent, and was
due mainly to the increased size of the fruit; the number of berries was apparently
little increased.
The berries were sold in the New Brunswick markets; the selling price averaged
10J cents per quart. There was therefore a gain of $5.54 per plat or $44.32 per
acre. The nitrate cost $45 per ton, which made the cost of the amount used $4.50
per acre, in reality a return of 10 cents for every cent invested in the nitrate. There
is no doubt but that this large increase in yield from nitrate of soda alone this year
was made possible by the presence in the soil of considerable amounts of mineral
elements supplied by the dressing of phosphate and potash in 1889, though it forcibly
illustrates the profits that may be derived from special manuring.
Report of horticulturist of Maryland Station, T. L. BRUNK
(Maryland Sta. Report for 1891, pp. 379-424, figs. 8).
Synopsis.-The subjects treated are (1) the station orchards; (2) spraying experiments;
(3) spraying apparatus; (4) test of varieties of tomatoes; (5) potted vs.
transplanted tomato plants; (6) fertilizer test with tomatoes; (7) test of varieties
of strawberries, blackberries, and lettuce; (8) root rot of peas; and (9) winter
budding.
The station orchards (pp. 379-391).-Notes and tabulated data on experiments
with Paris green combined with ammoniacal copper carbonate,
copper carbonate and carbonate of ammonia, or kerosene emulsion
and copper carbonate, on apple trees of the Winesap and Limbertwig
varieties. Ravages by insect pests were diminished by the treatment,
but as regards fungous diseases the results were inconclusive. Paris
green in combination with the copper compounds was quite injurious to
the foliage. The mixture containing kerosene emulsion was prepared
as follows:
Three bars (about 27 ounces) of Lenox soap [were first dissolved] in 3 gallons of hot
water. This was poured into a barrel or half barrel. and to it was first added 1
pound of carbonate of copper and 21 ounces of Paris green. The whole was then thoroughly
mixed with a large Lewis combination syringe by repeatedly spraying it back
into the barrel. The soap is a good suspender of both the carbonate of copper and
Paris green. Six quarts of kerosene oil were finally added and thoroughly churned
