About Me

My photo
As an Agriculture Extension Agent for Texas AgriLife Extension Service I have had an opportunity to be involved in just about every aspect of agriculture. From the 5,000 cow dairy to the types of trees to use in a home landscape I have had a chance to learn how the different parts of an agriculture systems work together. Seedless watermelons, drip irrigation, pecan orchard management, fruit crop development, dairy nutrient management, environmental issues confronting agriculture, producer tours, field days, research projects and more have been a part of my life for over 30 years as I lived and breathed agriculture. Since 2004 I have been actively involved in consulting internationally working in Honduras, Guatemala, Egypt, Jordan, Iraq, India, and China. I have worked with missionaries and other groups dedicated to alleviating poverty among third world farmers. I lived in the Middle East in 2007-2008 working on a project for the Borlaug Institute of International Agriculture at Texas A&M University. In this project I was the Chief of Party and Team Leader for a $5.7 Million dollar effort to train Iraqi Extension agents and specialists in all aspects of agriculture.

Tomato Variety Trial

Stiles Farm Foundation, 2010
Bob Whitney and Archie Abrameit
Williamson County

Summary: The population of Texas continues to grow but the majority of that growth is centered along the I35 corridor. Latest population estimates show Travis County with 921,000 people, Williamson County with 354,000 people and Bell County with a population of 258,000. This puts Williamson County with its rich soil and moderate climate in the middle of one and half million people, all who eat and want lots of good food every day. Recent trends in the US point to more and more consumption of locally grown food products and at the top of the list is a desire to buy locally grown vegetables, fruits and nuts. Farmer's Market interest is at an all time high and more and more cities want a Farmers Market for their citizens. The local community supports the growth of small farm agriculture that supplies nutritious and healthy, locally grown farm products.

Because of this interest there are more growers and these growers want information to make informed decisions on varieties, fertility, irrigation, harvest and more. This test evaluated 19 popular and new tomato varieties.

Objective: To evaluate 19 tomato varieties for vigor and fruit set.

Materials and Methods: The Stiles Farm Foundation is a typical blackland soil and the test was planted in a Sunev series. PH of the site is 8.0; Nitrate was 15 ppm, 63 ppm P and 336 ppm K. Site was prepared in March. Beds were fertilized with 100 pounds of 21-0-0-24 in March and incorporated. Transplants were put in the beds on April 8. Varieties were planted 4 plants to a rep with 2 total reps per variety for a total of 8 plants. Spacing was 2.5 feet in the row and rows were 8 feet apart. Planting pattern is outlined in Table 1. Plants were drip irrigated on timed irrigations.

How Much to Water?

I am asked over and over how much do I need to water my lawn. Extension has developed recommendations that in general say you should water 1 inch per week. These are general because of differences in soil, plant, rooting depth and even shade. We have a weather station here at our Extension office that is programmed to help landscapers and homeowners know how much water they need. The information is available on texaset.tamu.edu and is fantastic. I have signed up for a weekly notification on the website so that it sends me an email and tells me how much to water for every week. I get the email on Friday and can water through the weekend to replace what was lost during the week to evapotranspiration. Evapotranspiration is the water lost from the soil surface and the plant together. I have told the program that I have bermudagrass for sod and I want normal growth. Here are the recommendations.
Date     Evapotranspiration
07/09    0.15
07/10    0.18
07/11    0.26
07/12    0.24
07/13    0.26
07/14    0.29
07/15    0.28

7 day watering recommendation for Bob Whitney:  0.60 inches  (assuming no rainfall)*
Plant Coefficient: Warm Season Turfgrass
Adjustment Factor: Normal

Pecan Field Day Set for August 11

Texas AgriLife Extension, Williamson County, has planned a Pecan Field Day for Wednesday, August 11 at Berry Springs Park and Preserve at 1801 CR 152 near Georgetown. Registration for the field day will begin at 9:30 a.m. with the program beginning at 10:00 a.m. and lasting through a sponsored noon meal. Cost of the Pecan Field Day is $5 per person. The Pecan Field Day will include two hours of Continuing Education Credits for private, commercial and non-commercial applicators.

Individuals with disabilities who require an auxiliary aid, service or accommodation in order to participate in this tour are encouraged to contact the Extension office at 512/943-3300 by August 6, 2010 to determine how reasonable accommodations can be made.
Discussing pecan weevil, pecan yellow and black aphids and other insect problems growers face will be Mr. Bill Ree, Extension Pecan Entomologist. Bill is based in College Station with state-wide responsibilities for educational programs in pecan insect management and is a great resource for pecan growers. This date for the Pecan Field Day should correspond with previous years dates for making the first pecan weevil sprays. The field day will be a great opportunity to catch up on the latest management of pecan insects and sightings of pecan weevil.
Next on the program will be Monte Nesbitt, Extension Horticulturalist and State Pecan Specialists for Texas AgriLife Extension Service. Monte was on our program in May and everyone enjoyed his discussion very much. Monte will discuss more about variety selection for production and less problems, some information on planting trees this fall and winter, care of trees in August and September and orchard preparation for harvest.
Sponsors for the Pecan Field Day include Dow AgroSciences.

Bacterial Leaf Spot of Tomato

Greasy Spot Fungus on Meyers Lemon

Greasy spot fungus can wreak havoc on citrus trees if not controlled. The fungus is shown on both sides of the leaf. Prevention is easy. Remove all fallen leaves which are the source of more fungus and do not get water on the leaves if possible. Treatment if necessary is with a copper based fungicide.
