Successful stand establishment of a corn crop relies on many factors, including the successful emergence of the seedlings in the first place. Seedling emergence occurs as a result of elongation of the mesocotyl that elevates the coleoptile or “spike” toward the soil surface.

Wheat has greened-up and is actively growing across Indiana. Our southern field plots in Vincennes were at Feekes 8 (flag leaf emerged) earlier this week, while in West Lafayette plots are at Feekes 5 (leaf sheath strongly erect).





Wild garlic (Allium vineale) has shown up in many Indiana no-till corn and soybean fields this spring especially, in southern Indiana.  Wild garlic is most troublesome in wheat, where aerial bulblets contaminate harvested grain and impart the garlic flavor into processed products such as wheat flower.  Infestations in corn and soybean fields have less adverse effects on the crop, but can spread quickly across fields and are difficult to control with typical burndown treatments of glyphosate and 2,4-D. Management of wild garlic must occur early in the spring as this perennial will quickly become reproductive in mid to late spring.  Wild garlic produces aerial bulblets and begins to senesce in late spring to early summer.  As with all weeds, wild garlic management needs to occur prior to seed or in this case bulblet production to reduce future infestations.  Ideally herbicide applications should take place in early April when the wild[Read More…]

Conventional wisdom says that the prime planting “window” to maximize corn yields in much of Indiana opens about April 20 and closes about May 10. This “window” typically opens about one week later across the northern tier of Indiana counties (later warmup) and about one week earlier across the southern tier of Indiana counties (earlier warmup).
