PtNNSTATt Pennsylvania Commercial Hybrid Corn Tests Report Tests of commercially available corn hybrids arc conducted annualh at several locations in each of the four maturity zones in Penns\l\ania to provide farmers, seed producers, county exten sion agents, and other interested persons with information about Inbnd 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 are for the adumced hybrids tested previously for at least one year, and those in Table 2 are for new hybrid entries. New entries are tested tor at least one year before being included in the advanced tests. A two-year summary of results for hybrids tested in both 1992 and 1993 growing seasons is given in Table 3. The results tor hybrids entered in the silage performance test are given in Table 4. Procedures This testing program was available to any producer of hybrid Corn Tests Report Cooperators and locations Early medium-season hybrids were evaluated with the coopera tion of the following persons: Craig Richards, Columbia County; Curt Rakestraw. Lycoming County; Harold Foertsch, Butler County; Bill Hoagland, Mercer County; and Penn State farms. Centre County.

For the grain tests, hybrids were planted in paired-row plots of 1/500 of an acre. Each row was overplanted—34 kernels 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 overplanted 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 for each hybrid was based on the mean of five check (Maturity Zone 2) 1993 results EASTLAND ES9IA NORTHRUP KING N 5220 AGWAY AG 578 PIONEER 3527 OOEBLER S 65XA AGRI GENE AGS66O CARGILL 6677 CFS W 5559 AGRI GENE AG6363 DEKALB DKSBO JACQUES EXP3OIO AGWAY AG EXP 622 CFS W 5767 ICI 8501 OOEBLER S66XP FUNK S G-4472 NC+ 4521 GREENLAND GL223 ASGROW RX7O7 GREENLAND GL2II AGWAY AG EXP 631 DOEBLER’S 64XP AGWAY AG 626 PRAIRIE STREAM SX4I2 ANOERSONS PSX4OS NC+ 5037 MEANS ISO ( 05) LOCATION MEANS Centre Lycoming Mercer Centre TWO-YEAR AVERAGE PERFORMANCE Trtbir 3 Early medium season hybrids moan performance 1992 1993 (Maturity Zone 2) BRAND-HYBRID HY PERFORMER H 59330 89 3 DOEBLER’S 58XP 90 9 HALSEY H 296 92 6 DEKALB DKS24 93 3 PIONEER 3733 93 7 DOEBELR S 57XP 96 3 HARDY H 86500 97 4 PIONEER 3527 97 8 NORTHROP KING N 4545 97 8 DOEBELR S6SX 1011 JACQUES 6970 101 9 DOEBLER S 62XP 102 6 HALSEY HI 10SA 102 6 NC+ 4275 103 3 EASTLAND E 599 103 3 HYTEST HTSI2 103 7 CARGILL 6269 103 7 DOEBLER S64XP 104 1 FUNK'S 0*4472 105 8 GRIES QSFSIO6 105 6 OOEBLER'S 66XP 106 3 1C16513 106 3 NC+ 4616 107 0 AGWAY AQ-658 107 4 HYTEST HT536 108 1 GRIES QSF 6110 108 9 SCHLESSMAN SXB6I 1111 GRIES GSF 6112 113 0 MEANS LSD ( 01) 101 9 39 Ki suits ol the tests lor short season c.irly medium season, lute medium sc isoii and late season hybrids are available as separate reports from county ollu.es ol Penn Stale Cooper idee 1 xtension Members ol ihe county haseil extension stall assisted in conducting these tests Their el torts were essential to the succcsslut completion ol (he dials, and were greatly appreciated I his report represents the combined el torts of extension roseate h and siixicc personnel in (he Departments ol Agronomy and Plant Pathology (MW Johnson KI Williams and J L Ayers) tin inhh \ in ilm it pm I inn\ !u n /noihii t il <>nl\ in tin n i mm i\ (Turn to Pago 14) 102 7 83 101 4 37 100 7 101 2 101 0 963 121 5 102 4 97 6 89 3 94 1 101 2 108 4 101 9 PERCENT-OF CHECKS K z o YIELD ERECT %H*o BUM % GRAIN GRAIN ERECT 124 9 99 122 9 100 145 4 122 6 1166 107 0 23 8 25 6 27 4 25 6 98 1 96 6 98 4 93 8 SILAGE ENTRIES Table 4 SHaqe performance ol r uly medium season hybrids (Maturity Zone <?| BRAND-HYBRID OOEBLER S 69XP AQWAY AG 626 DEKALB DKS6B HY PERFORMER HY9334 26 0 AGWAY AG 723 26 4 CARGILL 5X269 26 4 GOBBLER'S 75XMOD2 26 8 GREENLAND GL262 26 8 PIONEER 3527 26 2 HYTEST HT525 28 5 WETSEL Sl2O 26 6 PIONEER 3394 29 8 MEANS LSD ( 05) Winn if wh nmiHv jp|H if no nvlmsriiKßl hy Cum Si ik < <i Issllul 111 fllllhuKlKl 1( H |Kt HIM I Hill M i\ « mil Jiiim 'll l'M4 in uhijx i limn * Avimiliiih imhht I’rnnsylvamt I iyisl m ( iNifKfHiiM I vinsiim ni< Centisili mi r Ihr IVnnsil* him Si iu I imursiu is loimitiiiiil in ilk jhilk i ih ii ill pusiins >H ill him u|inl wu» I |hoj.iiiii' (minus iiliiiissi hi nul ini|tloMiH hi mihmit npjfil 11 ixiMHt il ih ii i iuimk' umnl ii»il i ihilm p» riiinii nut m i|h.ililk jihhis is ik iitmim I hi I nisirMU |» lu \ h l»\ Si Hi K lotlrr il aulhiKilHs Ihi ISniisili mi iSi Hi I mvi rsiu <1 h s imi ills riiinii ih ip tins) in\ pi i son hn ms 1 1 >u iiK»s|rv mini ills ihilm i II liullt l|l 11 II II ill ll IHlpm Ikl nil).
