26 REPORT ON EXPERIMENT STATIONS, 1952
More than 75 percent of the shade tobacco grown in the Connecticut
Valley in 1952 has been planted to two new strains, Connecticut 15
and 49, developed in the Connecticut Agricultural Experiment Station's
improvement program. Connecticut 15 accounts for half of all
the shade tobacco acreage grown in Connecticut and Massachusetts.
It outyields the strains it has replaced, its leaf color is lighter and
more uniform, it produces more high-grade leaves per plant, and its
leaf shape is superior. It is also resistant to black root rot and flea
beetles, which previously caused shade growers much concern. Connecticut
49, developed later and grown on 25 percent of the 1952 shade
tobacco acreage has most of the excellent qualities of Connecticut 15,
produces a more elastic leaf-important in cigar manufacture-and
its taste is rated as better by some experts.
FORAGE CROPS, PASTURES, AND RANGES
Recent advances in mechanization have made grassland agriculture
more practical and economical. New and redesigned machines make
it possible to seed and manage pastures and hay crops with less labor
and a smaller expenditure of time. Better harvesting equipment has
resulted in higher quality forage and reduced costs, and the increase
in production of grass and legume seed has created a demand for more
efficient seed harvesting and processing equipment. Such machinery
is being developed by the close cooperation of the State experiment
stations, the Department, and machinery manufacturers.
Increased attention is being given to the production and utilization
of forages and pasture crops and a great amount of research is being
devoted to rangeland improvement. One of the high lights of the past
year was the Sixth International Grassland Congress held at The
Pennsylvania State College. This was the first time the Congress had
been held in the United States and it afforded an excellent opportunity
for research workers and others interested in grassland agriculture to
exchange information and to study new methods and techniques used
in many parts of the world. Grassland agriculture is comparatively
new in the United States and the findings of research in other parts
of the world are of great value to our own research workers.
Much attention is being given to the many phases of forage crops
research at all of the State experiment stations and the following
paragraphs present only a few examples of such research in a few of
Pasture and Meadow Irrigation
In areas of low rainfall irrigation of pastures and hayland has long
been a standard practice; in other sections of the country, however,
supplemental irrigation of pastures is a new development and much
important research work in this field is now under way.
The Georgia station found that supplemental irrigation on a
Bermuda grass-Ladino clover pasture increased the dry forage 27
percent and the protein 67 percent. However, this heavier yield
called for increased fertilization, especially with nitrogen.
At Dixon Springs the Illinois station (coop. USDA) found that a
pasture irrigated seven times with 2-inch applications during the 1951
