The biggest topic seems to be how wet it is and how much more rain Indiana can expect. So far, May has experienced near-normal precipitation throughout the central part of the state with 0.5”-2” in southern and northern regions (Figure 1).

Adoption of Xtend soybeans is expected to reach 70-80% of the soybean acres in the U.S. in 2019. The approval of Enlist E3 soybean imports by China and the Philippines earlier this year has allowed for full commercialization in the U.S. and provided farmers with another auxin herbicide (2,4-D choline) in their soybean weed management programs.
Delayed planting seasons create a lot of frustrations for everyone involved with planting crops. One of the agronomic questions that comes up when planting is seriously delayed is whether farmers should consider switching from their normal full-season maturity hybrids to shorter-maturity hybrids. The question is based, of course, on the perceived risk of the crop not reaching physiological maturity before a killing fall freeze and the yield losses that could result. A related, and economic, concern with delayed planting of normal full-maturity hybrids is the risk of high grain moisture contents at harvest and the resulting costs incurred by artificial drying of the grain or price discounts by buyers. Bottom Line Delayed planting certainly reduces the growing season for corn, both in terms of calendar days but more importantly in terms of available GDDs for the plants to safely mature before a fall frost or killing freeze. The good news[Read More…]
Rain, rain, go away! I hesitate to scream that too loud, though, for fear of a drought. That seems to be the weather and climate, these days – one extreme or another.
Every spring we receive several calls and e-mails about a certain 3-foot tall weed with yellow flowers. This year, cressleaf groundsel is slower to develop, presumably because of the extended cold and wet weather which has not allowed much field work (spring tillage or burndowns for no-till) to proceed.
Even though rainy conditions continue to slow planting across the state, we need to keep an eye on winter wheat. These wet conditions will favor many fungal diseases.
The prospect of delayed planting of corn leads corn growers to consider whether changes in seeding rate should be made in response to late planting. The short answer is that optimum plant populations probably remain the same regardless of planting date.
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.
No reason exists to expect drought anytime soon in Indiana, with much of the state remaining rather wet after last weekend’s showers. One good new development exists.
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).
