Last week when the heavy frost hit us, air temperature at Southwest Purdue Ag Center (SWPAC) in Vincennes, IN dropped to 24°F. We did not take action for frost protection on the strawberries growing with the annual plasticulture system, considering only two early cultivars start to bloom at that time. However, this appears to be…Read more about Strawberry Frost Protection[Read More]


Bolting of crops overwintered in high tunnels is common in the spring. ‘Bolting’ refers to lengthening and blooming of the flowering stalk. Bolting is often a problem because the quality of the marketable part of the plant declines. Also, plants subject to bolting are programmed to die once they complete flowering and seed production so…Read more about Bolting and Blooming in High Tunnels[Read More]


At the Pinney Purdue Ag Center in northern Indiana we had plots in 2020 with no-till sweet corn, pumpkins and winter squash following a rye cover crop. As is common when adapting new planting and tillage systems, we had both challenges and successes. Check out the video presentations to see photos of the plots, and…Read more about No-till Sweet Corn, Pumpkin and Winter Squash after Winter Rye – Reports from 2020[Read More]


Melon is a crop with diverse fruit characteristics. They have different color, shape, rind pattern, texture, and flavor. In major food stores, cantaloupe and honeydew melons may be the only melon types sold, while the fantastic experience of melon consumption is far more than that. This created an opportunity for selling unique melon fruit at local farmers’ market and with a potentially higher price. It…Read more about Specialty Melon Evaluation in Southern Indiana[Read More]


Carl Cantaluppi is a retired Area Horticulture Agent, North Carolina Cooperative Extension Service.

This article addresses considerations of using grafted watermelon plants in Indiana. Choosing rootstocks Interspecific hybrid squash is the most widely used watermelon rootstock. Many cultivars of the hybrid squash rootstocks that have been developed by different companies, share similar genetic background and thus similar characteristics. All of them have outstanding resistance to Fusarium wilt, but,…Read more about Using Grafted Watermelon Plants in Indiana[Read More]


Cover crops have been shown to improve water and soil quality, reduce erosion and capture nutrients. Choosing the right cover crop, however, can be difficult. The Midwest Cover Crops Council (MCCC) —made up of representatives from 12 Midwest states and universities, including Purdue, the province of Ontario and other agricultural stakeholders — is rolling out an improved cover…Read more about Improved Tool can Help Midwest Farmers with Cover Crop Decisions[Read More]



Strawberries are primarily grown in matted row system in Indiana, in which bare-root strawberry plants are set in the spring. Runners are established. Fruit is first harvested in the second year and plantings are renovated each year for 2-3 seasons. Growers in the southern part of the state expressed interest in growing strawberries in plasticulture…Read more about Using Low Tunnel is Promising to Increase Yield of Annual Plasticulture Strawberry Production[Read More]


Question: What happened to these fruit? Answer: Hail damage. A storm that happened in middle July brought hail to parts of Indiana. Hail hit small fruit, and damage became pronounced as fruit grow. More information about the damage to vegetable crops can be found in the article Hail Damage published in Vegetable Crops Hotline Issue…Read more about Answer to Question from Last Issue (8-13-2020)[Read More]
