'Yow-to" Hintsjor May Gardeners Grow Your Dum "Great Pumpkin" Gardeners who have an interest in pumpkins specifically-and competi­ tion in general-should this month begin sowing the seeds that could lead them to produce the world's largest pumpkin. "Great pumpkin" growers may enter their gigantic squash in this year's World Pumpkin Weigh-Off, and win not only fame and glory, but also substantially large cash prizes. The Weigh-Off is spon­ sored by the World Pumpkin Confed­ eration, headquartered in Collins, New York, and will take place in Oc­ tober of this year in nine locations around the world. Last year, Bob Gancarz, grower of the gargantuan winning entry, which weighed in at a whopping 671 pounds, received a to­ tal of $4,000 in prizes. Now that you have all the inspira­ tion and incentive you need, here are a few practical tips from Wayne Bob Gancarz and his brother Ed, shown here with Bob's record-setting 671-pound Hackney, Eastern States Champion pumpkin, dominated the World Pumpkin Weigh-Off in Collins, New York.
