sts and the annual cover-crop follows
cultivation. Many varieties, if vigorous, will set some fruit in this
second summer, but the crop should not be allowed to mature, the
sooner removed the better, as fruiting at this stage of growth
seriously weakens the young vines.

CATCH-CROPS AND COVER-CROPS

A catch-crop is one grown between the rows of another crop for profit
from the produce. A cover-crop is a temporary crop grown, as the term
was first used, to protect the soil, but the word is now used to
include green-manuring crops as well. Catch-crops seldom have a place
in most vineyards, but cover-crops are often grown.

_Catch-crops._

Catch-crops are not, as a rule, profitable in commercial vineyards;
they may bring temporary profit but in the long run they are usually
detrimental to the vines. It may pay and the grape may not be injured
in some localities, if such truck crops as potatoes, beans, tomatoes
and cabbage are grown between the rows or even in the rows for the
first year and possibly the second. Land, to do duty by the two crops,
however, must be excellent and the care of both crops must be of the
best. Growing gooseberries, currants, any of the brambles, or even
strawberries, is a poor procedure unless the vineyard is small, the
land very valuable or other conditions prevail which make intensive
culture possible or necessary. The objections to catch-crops in the
vineyard are two: they rob the vines of food and moisture and endanger
them to injury from tools in caring for the catch-crop.

Sometimes the grape itself is planted as a catch-crop in the vineyard.
That is, twice the number of vines required in a row for the permanent
vineyard are set with the expectation of cutting out alternate vines
when two or three crops have been harvested and the vines begin to
crowd. This practice is preferable to inter-planting with bush-fruits,
yet there is not much to commend it if the experience of those who
have tried it is taken as a guide. Too often the filler vines are left
a year too long with the result that the permanent vines are checked
in growth for several years following. The profits from the fillers
are never large, scarcely pay for the extra work, and if the permanent
vines are stunted, the filler must be put down as a liability rather
than as an asset.

_Cover-crops._

In an experiment being conducted by the New York Agricultural
Experiment Station, grapes do not give a very appreciable respon
