1999 Pa. Commercial Hybrid Test Reports Short-season hybrids (Maturity Zone 1) 1999 results How to use this report This report provides independent and unbiased information (or the evaluation of commercial com hybrids available in Pennsylvania. It should be used to supplement other sources of information, such as seed industry performance tests, other Tests of commercially available corn hybrids are conducted independent testing data, and on-farm performance records annually at several locations in each of the four maturity zones in when making hybrid selection decisions. Pennsylvania to provide farmers, seed producers, cooperative The first factor to consider when using this report is extension agents, and other interested persons with information hybrid maturity. The hybrids listed in Tables 1,3, and 4 are about hybrid performance. This report includes both the grain ranked in ascending order by grain moisture with the earliest and silage results from the 1999 season, hybrids (lowest grain moisture) at the top. In Table 2, hybrids Table 1 contains the combined results for all locations are listed alphabetically. Grain or silage moisture is a good harvested in this zone. Table 2 contains the yield data generated indicator of hybrid maturity; those with lower moisture are at eac |, location. We believe that the statewide performance generally adapted to shorter season environments. Identify averages found in Table 1 are most important to consider when hybrids in the list that you know are adapted to your area, making a final decision about variety capabilities, since they and then evaluate new hybrids that have similar moisture contents. Selecting hybrids based on yield alone may result in a hybrid that is too late for your farm. Note that there is considerable range among maturity in hybrids entered in each zone. Once you have identified the appropriate hybrid maturity range, compare the yields of the hybrids that have been evaluated Yield performance is variable across locations and is best predicted by using data averaged over multiple locations, so the mean yield overall sites is the best guide to hybrid performance. Individual location hybrid means (Table 2) can help to assess how consistent, or stable, the hybrid was across locations. For example, some hybrids may do well at high yielding sites but may not do well at low-yielding sites. We DO NOT recommend using data from a single site, even if it is close to your farm, to make hybrid selection choices. Once you have identified some prospective hybrids, consider their standability from the erect plants column as well as any disease rating data that may have been collected. It also is important to check with a seed company representa tive about other characteristics of the hybrid that may be important for your operation. Once you have gone through this process, you should be Have you been looking for great yields from your corn? Then look no more, because we've found just what you need.

This is an important part of profitable com production, since, as these reports demonstrate, there is a wide range in the performance of com hybrids. Further, we recommend that you evaluate selected hybrids on your farm under your growing conditions and practices. This is the best way to make a final determination of the proper hybrids for your operation. Corn Talk, Lancaster Farming, Saturday, January 29, 2000—Page represent a wide variety of growing, soil, and management conditions. A two-year summary of results for hybrids tested i both 1998 and 1999 growing seasons is given in Table 3. The results for hybrids entered in the silage performance test are reported in Table 4. Procedures This testing program was available to any producer of hybrid seed corn For the grain tests, hybrids were planted in paired-n plots equal to 1/500 of an acre. Each row was over-planted (30 kernels per row) and thinned when the corn was 12 to 18 inche tall. The final population was 26,000 plants per acre Silage pic were 1/1,000 acre in size, consisting of one row over-planted h 32 kernels and thinned to a final population of 28,000 plants pc acre. All gram entries were replicated three times in each test while silage entries were replicated four times. Cooperators am planting and harvesting dates are shown in Table 5.
