Abstract
Experiments were conducted from 1976 to 1978 at the
Arlington Experimental Farm, Arlington, Wisconsin, to study
the effect of planting dates, row widths and herbicide
treatments on 'Hodgson1 and 'Wells' soybeans. Additional
studies were conducted at Janesville, Wisconsin, in 1976
and 1978 "but one date of planting was used. Yield decreased
with delayed planting. 'Hodgson' consistently outyielded
'Wells'. Soybeans planted in 10-inch rows yielded more than
those in either the 7- or 30-inch rows. Except at Arlington
in 1976, a postemergence application of bentazon did not increase
yield significantly.
In 1978 a John Deere planter was compared with a Tye
soybean drill and an IHC grain drill to study their effect
on soybeans planted in 7-» 10-, 20- and 30-inch rows. For
most soybean characteristics studied, the Tye soybean drill
was not different from the John Deere planter but was superior
to the IHC grain drill.
The effect of fungicides on seed quality was studied
in 1978. 'Evans', 'Hodgson', 'Wells' and 'Beeson' soybeans
were used in Experiment 1.where different rates of benomyl
were compared and only 'Wells' was used in Experiments 2, 3
and 4 in which benomyl and thiabendazole were compared.
Also the effect of cultural practices mentioned above were
studied. 'Evans' yielded highest but was the most susceptible
to Maporthe and Alternaria. Susceptibility decreased
with lateness in maturity. The best disease control was
obtained when 1/2+1/2 Ib/a of benomyl was applied at RJ and
R6 or 1+1 Ib/a applied at the same times. Little response
to fungicide treatments was found at Arlington. Seed infection
decreased with delayed planting. Row width and
herbicide treatments did not affect seed quality.
