When Should I Start Irrigating My Corn?
The recent stretch of dry weather has prompted much conversation about the proper time to initiate irrigation for corn. This scenario usually generates a lot more anxiety than necessary because early season wilting is certainly not something we are very accustomed to.
Use a Sound Corn Nitrogen Strategy to Combat Rainy Weather
Abundant spring rainfall can create havoc with corn nitrogen management by delaying fertilizer application and also promote massive nitrogen loss. These strategies should help enhance crop response during challenging conditions.
Wheat Disease Update: April 24, 2015
For the most part the Mississippi wheat crop is clean with regards to foliar diseases. However, some important issues are occurring that need to be addressed with regards to Fusarium head blight, stem maggot feeding, and general herbicide injury as these three issues can easily be confused with one another at the field level.
Grain Sorghum Planting and Seeding Recommendations
Strong markets are driving Mississippi growers to plant a lot more grain sorghum than what could have been, considering the recent development of Sugarcane aphids as a threat to sorghum production. This article gives guidelines for getting your sorghum crop off to a good start.
Are We Going to Get this Corn Crop Planted?
Much like the last 2-years, as rains delay corn planting progress, more concerns arise regarding whether you will have ample opportunity to plant your corn crop in a suitable time window. This article states new guidelines for late corn plantings based upon recent MSU research.
2015 MSU Grain Sorghum Hybrid Suggestions
This effort lists those grain sorghum hybrids which have demonstrated superior productivity in the MSU MAFES Grain Sorghum Hybrid Trials and neighboring University trials. This information should help you pick well-suited sorghum hybrids for Mississippi.
2015 Spring Nitrogen Fertilizer Recommendations for Wheat
Environmental factors play a substantial role in nitrogen fertilization for wheat producers in the Mid-south. This article gives guidelines for getting optimal wheat response to your nitrogen fertilizer.
2015 Delta Ag Expo, Cleveland, MS – January 21 and 22, 2015
Find attached the agenda for the 42nd Annual Delta Ag Expo to be held in Cleveland, MS on Wednesday, January 21 and Thursday, January 22, 2015. We hope to see you in attendance at the Bolivar County Ag Expo Center.
2014 Wheat Variety Evaluations for Tolerance to Metribuzin Herbicide
Metribuzin is an important herbicide for controlling numerous weed species in wheat. However, wheat varieties may differ in tolerance to metribuzin. These are the results from our evaluation of wheat varieties included in the MSU Wheat Variety Trials. This should help you better assess potential for wheat crop injury.
2014 Corn Hybrid Demonstration Program Results
The MSU Corn Hybrid Demonstration Program evaluates superior corn hybrids from numerous seed companies who market corn in Mississippi. Our objective is to provide you more opportunity to evaluate premier corn hybrids and substantially supplement the independent and unbiased information gathered in the University Hybrid Trials.
2015 MSU Short List of Suggested Corn Hybrids
This effort lists those corn hybrids which have demonstrated superior productivity in the MSU Corn for Grain Hybrid Trials. Approximately 80 corn hybrids representing the vast majority of seed companies in the Mid-South participate in the MSU hybrid trials. This information should help you better assess corn hybrid productivity and improve your success in future seasons for either irrigated or dryland culture.
Keys for Seeding High Yielding Wheat
Wheat can be successfully established and grown using many planting methods, but several management practices can certainly enhance your potential for growing a productive crop this season. Those practices include timely planting, appropriate seeding rates and methods, suitable seedbed preparation and fall weed control.
2014 MSU Short List of Suggested Wheat Varieties
This publication lists those wheat varieties which have demonstrated superior productivity in the MSU Wheat and Oat Variety Trials and summarizes their characteristics. This impartial information should help you better assess wheat varieties which are best suited for your farm.
When is it safe to Apply a Grain Sorghum Harvest Aid and what to Expect?
Many growers in the Mid-South apply a herbicide shortly prior to sorghum harvest to facilitate combine efficiency and suitable grain moisture. This season, this issue is even more critically important because of severe harvest problems potentially created by White Sugarcane aphid infestation. This article will discuss appropriate timing and potential outcome of such harvest aid applications.
Preliminary Wheat Variety Yield Data
Preliminary yield data from the 2014 MSU Wheat Variety Trials are now available. This article provides suggestions for analyzing and making variety selection decisions using this data.
What Should You do about Late Southern Corn Rust?
Southern corn rust continues to be observed throughout MS. We continue to receive calls regarding late fungicide applications (> R4/R5) to reduce yield losses attributed to southern rust. Numerous myths regarding the disease have been widely spread throughout the MS corn production area including death of a corn plant in as fast as 7 days following southern rust infection and lodging as a result of heavy southern rust infection.
White Sugarcane Aphid Update – 8/1/2014
White sugarcane aphid infestations are increasing across the state and more applications are going out to manage this pest. Over the last week to 10 days we have heard about numerous fields that have received a second application. Remember, that the Section 18 label for Transform states that no more than 2 applications can be made in a field.
“It ain’t over till it’s over!” / Turnrow Talks
“It ain’t over till it’s over!” Amazing as it seems, several producers have not laid poly pipe. After the five plus inches of rainfall we received last week, some producers are questioning the need to lay pipe this late in
Vulnerability of Corn to Late-Season Issues?
Corn is not immune to yield loss until physiological maturity occurs. However, it is not nearly as vulnerable during late reproductive stages. This article includes a chart which should substantially help assess the risk of potential corn yield reduction during late reproductive stages.
Will We Need to Irrigate Our Corn Again?
Considering the abundant rainfall during June and the corn crop progressing closer toward maturity, many are wondering whether additional irrigation may even be needed. This article discusses how to make that and other late-season irrigation decisions.
Corn Disease Update: June 28, 2014
Foliar corn diseases continue to be observed throughout the MS corn crop. Common rust, gray leaf spot, northern corn leaf blight, and southern corn leaf blight are all present at low levels throughout the Delta. As of Wednesday (June 25, 2014), southern corn rust had only been observed in southeastern MS (Forrest, George, Greene, Jackson, Perry, and Stone counties).
Programing a Surge Valve
We are having lots of questions concerning the proper set up of surge valves. First, please consider some of the basic terminology associated with furrow irrigation. We encourage you to visit http://www.youtube.com/watch?v=46sSLFBUrh8 and view the video before continuing. Phases
Is My Soil Moisture Sensor Broke?
The importance of soil moisture sensors is becoming more evident as we continue forward this growing season. Today (Monday, June 16th), we received a call regarding sensor readings that were assessed early this morning. The following are the data discussed in this scenario.
How to Use Watermark Sensors to Assess Soil Moisture and Schedule Irrigation
Row crop irrigation needs are ramping up and one of the tools we can use to better assess soil moisture is Watermark sensors. This article describes how to analyze the data generated by sensors to help you better schedule irrigation.
