The 1956 sweet corn performance tests were conducted at Lafayette and North Liberty, Indiana, The Lafayette trials were located on the Agronomy Farm of the Purdue University Agricultural Experiment Station and consisted mainly of experi-mental hybrids. The trials at North Liberty were planted on the Purdue Muck Farm/3 & comprised 56 commercial hybrids and one experimental hybrid from the Purdue station.

Table 1 lists the commercial hybrids planted at Lafayette and North Liberty, due hybrid 48175 X 4619 was planted at both locations to evaluate it as a possible hybrid for release in the near future.

1. Trials at Lafayette. This planting was made May 16 and consisted of 4 groups of experimental hybrids developed in the sweet com project and one group of experimental and commercial hybrids from seedsmen.
Growing conditions throughout the season were ideal for sweet corn, with adequate moisture and moderate temperatures. The season was ideal for the development of
 and the tables indicate the percentage of ear infection in the various lots.

Each sample was replicated 4 times in single rows 10 hills long, checked 40x40 inches. Five kernels were planted per hill and later the stand was reduced to 3 plants per hill. Data on these trails include: rank based on yield in tons of
shucked green corn per acre, variety of pedigree of the sample, days from planting harvest, yield of green corn expressed in tons and dozens per acre, average weight per ear and percentage of ears infected with smut.

Table 2 summarizes the results from 8 early yellow hybrids developed in the corn project.

Table 3 gives the performance ratings of 43 experimental midseason yellow hybrids. Three commercial hybrids, 2057, Golden Harvest and Victory Golden were included for comparison.

Table 4 includes the results from trials of 8 experimental hybrids of Country Aleman type with Illinois Cogent 13 as a check.

Table 5 presents the results from trials of 6 experimental Evergreen hybrids compared with Keystone Evergreen, a commercial hybrid.

Table 6 summarizes the results of trials of 7 commercial and experimental midseason hybrids.

Conducted in cooperation with the Field Crops Research Branch, Agricultural Research Service, United States Department of Agriculture.
