Iron (Fe) Deficiency in Texas Crops Made Worse by Wet Weather

Dr. Calvin Trostle, Extension Agronomy, TAMU Dept. of Soil & Crop Sciences, Lubbock, (806) 746-6101,; June 9, 2021       Much of Texas has experienced heavy rains, cloudy conditions, and water-logged soils since early May.  Many crops will show signs of nutrient deficiency under such conditions.  These include iron (Fe) and nitrogen.   Symptoms for N and Fe nutrient deficiency may be confused with each other.  Nitrogen is mobile within the plant.  N deficiency leaf symptoms are expressed in older leaves.  This is usually a broad… Read More →

2021 Alternative Crop Options after Failed Cotton & Late-Season Crop Planting for the Texas South Plains

Dr. Calvin Trostle, Extension Agronomy, TAMU Dept. of Soil & Crop Sciences, Lubbock, (806) 746-6101,; Dr. Murilo Maeda, Extension Cotton Specialist, TAMU Dept. of Soil & Crop Sciences, Lubbock, (806) 746-6101,; This annual guide will be posted at by Monday, June 14.  Last year’s guide is essentially the same (see below) except crop prices for most crops are much higher, even 50% in cases.  The information remains applicable to the week of July 5th for a few late planting decisions like sunflower, grain sorghum, and… Read More →

Impact of Ponded Water/Flooding on Corn and Sorghum

Ronnie Schnell, Ph.D. Associate Professor and Cropping Systems Specialist Texas A&M AgriLife Extension, College Station   Tony Provin, Ph.D. Professor and Extension Specialist – Soil Chemistry Texas A&M AgriLife Extension, College Station   Numerous rain events have resulted in flooding or significant ponding of water in many corn and sorghum fields across Texas. While low-lying areas may be flooded, other areas of fields may be saturated for extended periods of time. How long can corn or sorghum survive under saturated or flooded conditions? What impact will these conditions… Read More →

2016 Alternative Crop Options after Failed Cotton and Late-Season Crop Planting for the Texas South Plains

by Dr. Calvin Trostle, Extension Agronomy, Lubbock, 806-746-6101, Hailstorms, wind damage, poor stands—and yes, occasionally too much rain(!)—place Texas farmers in a possible replant decision on a failed crop, usually cotton, or pushes planting back so much that cotton or other full-season crops are no longer viable. What to do? What are my options? New for 14th annual guide for the Texas South Plains are contributions from Dr. Seth Byrd, cotton extension agronomist, Lubbock, The guide is oriented to the South Plains, but producers in the… Read More →

Southern Plains of Texas: Scout for Thrips

by Suhas Vyavhare, Assistant Professor and Extension Entomologist, Lubbock, TX; and Blayne Reed It has been a very stop-n-go spring planting season for cotton in the Southern High Plains of Texas. Here we are again, waiting for rain to end so we can resume cotton planting. From Plainview north, an area consisting of our usually more calendar date conscientious producers, about 70% of the cotton has been planted while only about 50% South of Plainview. Rainfall this week has added much needed topsoil moisture helping dryland fields… Read More →

Sesame for Texas—High Plains & Rolling Plains

by Dr. Calvin Trostle, Extension Agronomy, Lubbock, 806-746-6101, Sesame is a heat-tolerant, drought-tolerant crop that has a good fit in much of Texas. Due to its small seed size it may present a planting challenge for some farmers (the right planter plates/discs and proper settings alleviate this), and due to just a few registered herbicides (Sonalan, some grass herbicides for mid-season control, Dual products) sesame is not for your weedy ground. But sesame has crop rotation advantages, wild hogs largely seem to leave it alone, and there… Read More →

Texas Wheat Producers Once Again Concerned with Pre-Harvest Sprouting

by Dr. Clark B. Neely, Extension Small Grains Specialist, So far, spring 2016 has been eerily similar to the spring of 2015 with wet conditions complicating wheat harvest for many producers in the state. In 2015, much of the pre-harvest sprouting (Figure 1) that occurred affected wheat in South Texas and the Blacklands. Low prices and the wet fall prevented many of the acres from being planted in this region for the 2016 crop. Though sprouting and crop failure in these region were or still are possible,… Read More →

Managing for Hessian fly in Texas Wheat

by Dr. Clark Neely, Statewide Small Grains Extension Specialist, Texas A&M AgriLife Extension Dr. Allen Knutson, Extension Entomologist, Texas A&M AgriLife Extension Hessian fly is a persistent threat to many wheat producersin portions of the Blacklands, the southern Rolling Plains (Concho Valley) and South Texas. Over 70 counties in Texas have reported Hessian fly infestations which can severely impact wheat yields through stunted tillers, lodging and even plant death in severe cases. In 2016, Hessian fly was detected at research plots near McGregor, Brady, and Thrall, TX (Fig… Read More →

Wet Conditions Leading to Yellow Cotton in South Texas: What Should Be Done?

by Dr. Gaylon Morgan, Professor and Extension State Specialist, 979-845-2425; It has been another wet spring and early summer for the Coastal Bend, Upper Gulf Coast, and Blacklands of Texas. The heavy clay soils in these regions are the lifeblood of crop production in the regions because of high water and nutrient holding capacity. However, these soils also drain slower and excessive rain can lead to prolonged saturated and anaerobic soil conditions. Under the saturated conditions, very little oxygen remains in the soil. Without oxygen in the… Read More →

Corn and Cotton Disease Update

by Thomas Isakeit, Professor and Extension Plant Pathologist; ,979-862-1340 Southern rust of corn (Puccinia polysora) (Figure 1) is present in fields in several Upper Coast counties. This disease has the potential to cause yield loss in susceptible hybrids and growers should be scouting for it. I have a bulletin that gives guidance for scouting, action thresholds for spraying, and a list of fungicides, at this address: I have frequently encountered common rust (Puccinia sorghi) this season. This is not a disease of concern in Texas. Northern… Read More →
