At the 2022 Southwest Indiana Melon and Vegetable Growers Annual Meeting, 17 watermelon farmers and 2 agricultural professionals shared their irrigation and fertilization management practices used for watermelon production in Indiana. These individuals grow or provide services for watermelon acres from less than 50 acres up to 2,000 acres over the past five years. We asked the percentages of watermelon acres using the different irrigation and nitrogen fertilization methods over the past five years. The figures below are the combined results from the respondents.
