Pumpkins are Ohio's third-largest fresh-market vegetable crop. Many non-traditional growers are planting pumpkins to increase gross income. Experienced growers have noticed that new producers are successful with low input. Are intensive production practices needed for a good crop? High and low input production schemes were studied, over 3 years on pumpkin yield and quality. High input consisted of Furadan at planting, reflective mulch, trickle irrigation, and a routine fungicide and insecticide spray program. Low input consisted of no mulch, no supplemental irrigation, and a reduced fungicide and insecticide program. The number of insecticide plus fungicide sprays for high vs. low input were: 10 vs. 5 in year 1; 5 vs. 3 in year 2; and 12 vs. 8 in year 3. Number and weight of marketable orange fruit in high-input plots were significantly higher than low input plots in year 1 and 3. Plastic mulch conserved soil moisture and resulted in 91% plant stand in high input vs. 57% in low input in year 1. The only year without a significant yield difference was when the difference in pesticide sprays was two. High input is suited for retail markets where the expectation is good yields of high quality pumpkins. Wholesale producers can probably get by with reduced inputs in certain areas.
