t PI Pennsylvania Commercial Hybrid Corn Tests Report I ests ol commercially available corn hybrids are conducted annually at seseral locations in each of the four maturity /ones in Pennsyhania to provide farmers, seed producers, county exten sion agents, and other interested persons with information about h>bnd performance. This report includes both the grain and silage results from the 1993 season. Tables 1 and 2 contain the combined results for all locations m this /one. except as noted. Those in Table 1 arc for the ad\ anccd hybrids tested previously for at least one year, and those m Table 2 are for new hybrid entries. New entries are tested lor at least one year before being included in the adumced tests. A two-year summary of results for hybrids tested in both 1992 and 1993 growing seasons is given in Table 3. The results for hybrids entered in the silage performance test are given 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-row plots of 1/500 of an acre. Each row was overplanted—34 kernels Corn Tests Report (Continued from Page 8) FUNK SG 4172 96 9 100 3 101 2 23 5 132 8 FUNK S G-2093X 96 5 104 0 100 7 23 5 137 7 ANDERSONS HSX44OII 96 0 85 0 102 2 23 8 112 5 PIONEER 3861 97 8 99 6 100 2 23 8 132 2 NORTHRUP KING N 4242 97 8 106 2 102 2 23 8 140 6 PIONEER 3751 100 5 101 7 101 1 24 4 134 7 FUNK SG 4106 100 8 94 7 98 4 24 5 125 4 AGWAYAG3IO 100 8 103 5 100 3 24 5 1371 DEKALB DK524 102 5 117 9 100 1 24 9 158 1 AGWAY AG 394 102 8 103 2 102 3 25 0 136 7 FUNK S G-4273 103 4 104 9 101 1 25 1 138 8 AGWAY AG EXP 322 103 4 109 0 100 5 25 1 144 4 HYTEST HT3IB 1035 1104 99 5 25 1 1462 HYTEST HTX723O 103 9 102 6 101 0 25 3 135 9 New Fact Sheets Available UNIVERSITY PARK (Centre Co.) Four new fact sheets on nutrient manage ment have recently been added to the Agronomy Facts series. A three fact sheet series entitled “A Nutrient Management Approach for Pen nsylvania” has been prepared by Les Lanyon and Doug Beegle. The first of these. Agronomy Facts #3B-A, is an introduction to the concepts of nutrient management and the nutrient management decision making process. The second fact sheet, Agronomy Facts #3B-B. discusses nutrient flows on farms and beyond. This fact sheet also presents a sug gested nutrient management classifica tion scheme for farms that can be used to help determine appropriate management considerations based on the individual characteristics of different farms. The third fact sheet. Agronomy Facts #3B-C, focuses on nutrient management decision making. It discusses the decision making process at various levels of management from making long-range strategic deci sions to making daily management deci sions. An overview of the steps involved in on-farm nutrient management is provided. A separate fact sheet, entitled “Nutri ent Management Legislation in Pennsyl vania,” Agronomy Facts #4O, provides an overview of the recently passed nutrient management legislation in Pennsylvania. All of these fact sheets will be available at local Penn State Cooperative Extension offices. 96 9 72 0 96 4 65 3 97 8 81 7 95 9 83 0 97 8 80 0 96 7 80 0 94 2 74 7 95 9 84 3 95 8 86 0 97 9 84 0 96 7 75 3 96 2 82 0 95 2 93 0 96 6 79 7 FOR LOW-COST VELVETUAF AND FOXTAIL CONTROL IN CORN, USC A PROW! TANK MIX PROM College of Agricultural Sciences Cooperative Extension Early medium-season hybrids (Maturity Zone 2) 1993 results per row, and thinned to a standard count of 48 plants per plot when the corn was 12-18 inches tall. The final population was 24,000 plants per acre. Silage plots were 1/1,000 acre in size, consisting of one row overplanled to 38 kernels and thinned to a final population of 28,000 plants per acre. All entries were replicated three times in each test. Test plots were planted with modified mechanical planters. Grain-test plots were harvested with a self-propelled combine equipped with electronic instrumentation for determining weight and moisture. Silage plots were harvested with a forage harvester. Grain yields are reported as bushels per acre while grain moisture and erect plants are reported as percentages. Shelled grain yields were standardized at 15.5 percent grain moisture. Percentage of checks lor each hybrid was basedsn the mean of five check hybrids and calculated for moisture, yield, and erect plants. Data such as plant height, ear height, and leaf disease ratings were taken in the field. Disease ratings were based on a scale of 0.5 to 5.0. progressing from little or no disease to premature death.
