An average-yielding watermelon crop in an acre accumulates approximately 150 pounds of both nitrogen and potassium in the vegetative tissue and fruit. These nutrients are supplied by the soil’s existing nutrient pool and through supplemental fertilizer applications. Soil testing is a valuable tool for assessing what nutrients are present in soils and the amount of…Read more about Lessons Learned: Nitrogen Fertilizer Management in Indiana Watermelon Production[Read More]
Crop Status Plug plants set on black plastic mulch in late summer and early fall are approaching full bloom. Some early blooms may have been damaged by recent low temperatures. Moving forward, growers should remain vigilant in protecting these crops from potential frost injury (Figure 3). Bare-root plants that were planted on white plastic during…Read more about Plasticulture Strawberry Update from Southern Indiana[Read More]

Some growers settle on a few favorite cultivars and focus on fine-tuning their production practices to suit them. Others prefer to explore new cultivars every year, selecting those that best fit their evolving production systems. Regardless…Read more about Considerations for Choosing Tomato Cultivars[Read More]
Passive solar greenhouses are widely used in northern China to grow crops year-round without supplemental heating. My former mentor introduced me to a project by the University of Missouri Extension, where they built a passive solar greenhouse. This past winter, I had the chance to meet Tim Reinbott at a conference and learned that his…Read more about Passive Solar Greenhouses[Read More]
