1 Pumpkin Germplasm Evalua1on Bob Precheur Dept. of Hor5culture and Crop Science Jim Jasinski OSU Extension, IPM Program Objec5ves To select those varie5es that have high yields over several years of produc5on. To select those varie5es that produce high quality, uniform fruit with very good handles. To determine those varie5es that have good disease resistance or tolerance. Trial Design 23 cul5vars Commercial & Experimental (mini, small, medium and large size) Randomized complete block design with 4 reps Evaluated at the Western Ag Research Sta5on in S. Charleston, OH. Fer5lity - Prior to plan5ng Broadcast 50 lbs/a of actual N lb/a P 2 O5 and K 2 O Sidedress with an addi5onal 50 lb of N/A before vine 5p. Trial Design Most hybrids direct seeded 30 May, some transplanted through 13 June Plots were 30 long, 15 row spacing, 5 between plots, 2-3 between plants Strategy and Dual Magnum were applied for weed control pre- emerge + lots of hoeing! Ca. weekly fungicide applica5ons star5ng at the end of July (alt. Quintec & Procure) Some hybrids exhibited low marketable yield due to heavy bacterial leaf spot pressure Crunchkin lb Avg.
