Grain Sorghum Planting Guidelines

Sandra Wick, Crop Production Agent

Producers are busy in the field planting corn and soybeans, however, it won’t be long and it will be time to plant grain sorghum. Well let’s hope that Mother Nature helps us out and keeps rain in our forecast! Our wheat continues to need moisture and our spring row crops need it to germinate and continue to develop.

Some of the main planting practices affecting yields in sorghum are: row spacing, seeding depth, seeding rate/plant population, planting date, and hybrid maturity.

Sorghum plants can compensate and adjust to different environmental conditions through adjustments in the number of tillers, head size, and the final seed weight. For sorghum, the final number of seeds per head is the plant component that varies the most; and thus has more room for adjustment than the other plant components (seed weight and number of tillers).

Let’s start with the Sorghum population or the seeding rate. Recommendations can vary significantly depending on your annual rainfall. So for north central Kansas the recommended seeding rate is approximately 35,000 to 64,000 seeds per acre with final stands of 25,000 to 45,000 plants per acre. Because of sorghum’s ability to respond to the environment, final stands can vary at least 25%, depending on the expected growing conditions, without significantly affecting the yields. Lower seeding rates help minimize the risk of crop failure in dry environments. Sorghum can compensate for good growing conditions by adding tillers and adjusting the head size, but yields can be reduced in a dry year if populations are too high. Sorghum will tiller more readily in cooler temperatures and less readily under warm conditions. Higher seeding rates also should be used when planting late and should be increased by about 15-20% if planting in late-June or even later. About 65-70 percent field germination is a good general rule to use. Row spacing goes hand in hand with the seeding rate. Using narrow row spacing, such as 15-inch compared to the traditional 30-inch row spacing, is significantly dependent on the environmental conditions especially moisture. 

A summary of research data performed at KSRE in the last several years has confirmed that the optimum planting date for maximizing yields will be around early June. Still, the decision related to the optimum planting date should be timed so plants have the best possible chance of avoiding the hot, dry weather at the flowering stage, but can still have sufficient time to mature before the first frost.

Seed placement or planting depth is also a critical factor in sorghum production. Optimum seed placement for sorghum is about 1-2 inches deep. Shallower or deeper planting depths can certainly affect the time between planting and emergence thus affecting early-season plant uniformity.

Lastly, but certainly not the least is hybrid selection. The selection of sorghum hybrids should be based not only on maturity, but also on other traits such as resistance to pests, stalk strength, head exertion, seeding vigor, and overall performance.

Gluten and Your Gut’s Good Health

Ashley Svaty, Nutrition, Food Safety and Health Agent

Many people have heard about gluten free diets but they may be misinformed about who should really follow a gluten free diet. May is Celiac Awareness Month, a perfect time to discuss what celiac disease is along with some myths that go along with gluten intolerance. Here are some quick facts about gluten, for more information please watch the video found here:

What is gluten?
Gluten is the protein in wheat, rye, barley, and some related grains that provides the elastic, chewy properties in breads and other baked products. The word gluten comes from Latin gluten, meaning “glue”. It is the glue-like characteristic that allows bread dough to stretch, but not break as it rises. Bakers select flours for the amount of gluten they contain. For example, high protein durum flour works well for pasta while low protein flour is used for cakes and pastries. Though gluten’s elastic properties are essential in baking and cooking, some people must avoid gluten to prevent gastrointestinal tract symptoms and even intestinal damage.

Who should follow a gluten-free diet?
Gluten has long been considered part of a sound diet for healthy people. However, for some people, good health depends on the elimination of gluten and wheat foods from the diet. People with celiac disease and others who are intolerant of gluten must adopt a gluten-free diet to control symptoms.

Celiac disease affects about 1 percent of the North American population. Celiac disease is an autoimmune disorder-the only where the trigger (in this case, gluten) is known. Celiac damages the villi of the small intestine where nutrients are absorbed. This may result in decreased absorption of nutrients from food, which can lead to dietary deficiencies. The symptoms vary greatly from one personal to another, increasing the difficulty of an accurate diagnosis.

Dermatitis herpetiformis is a type of celiac disease that not only results outwardly in a painful skin rash when gluten is eaten, but also damages the small intestine of most people with this condition. Diagnosis is made through a skin biopsy and blood tests.

Non-celiac gluten sensitivity (NCGS) differs from celiac disease because it is NOT an allergy or autoimmune disease. People with NCGS may have GI symptoms similar to people with celiac disease but there are no tests at this time to determine NCGS, but a diagnosis is made by the physician once celiac disease and other conditions are rules out.

How can I know if I would benefit from a gluten-free diet?
Overall, people diagnosed with the above gluten-related disorders should follow a gluten-free diet. The recent popularity of gluten-free diets is due in part to the increased diagnosis of the above conditions and also because of the dramatic health benefits noted by some who eliminate gluten from their diet in a personal effort to relieve symptoms. It is important to note that there are no published scientific reports supporting the idea of weight loss as a result of a gluten-free diet in people without celiac disease or gluten sensitivity. It’s not considered dangerous to eat gluten-free, but it can be overly restrictive and unnecessarily costly. Dieters may needlessly limit important nutrients such as iron, folic acid, and other B vitamins by excluding wheat foods and others that contain gluten if they choose to follow a gluten-free diet for other reasons than symptom relief.

If your health-care provider advises you or a family member to follow a gluten-free diet, there are many reputable resources available to help you. Here are just some that are available:

• Academy of Nutrition and Dietetics:
• Celiac Now:
• Celiac Disease Foundation:
• Celiac Disease, 2nd Edition: A Guide to living with gluten intolerance (2014) by Sylvia Llewelyn

Growing Tomatoes 101

Cassie Homan, Horticulture Agent

Tomatoes are one of the most common veggies grown in the garden and for good reason, nothing beats the taste of a juicy tomato on a hot summer day. Store-bought tomatoes just can’t compare with a fresh, ripe tomato picked straight from the garden. They are easy to grow and you don’t need to plant many to have a bountiful harvest. Here are some tips to have a successful tomato crop this year.

When to Plant
Plant tomatoes after all danger of frost is past. For North Central Kansas early May is a good time to starting thinking about getting your plants in the ground, although this year may be a little later than normal. Wait until soil is about 60F degrees before planting.

Most garden tomatoes should be spaced at least 18 inches apart to 2 feet apart in rows 3-5 feet apart. Newer varieties called dwarf tomatoes can be spaced closer, or planted in containers.

Tomatoes are usually grown from transplants. Choose a strong healthy transplant that has a dark green color and balance between the size of the plant and the container. Set the plant slightly deeper than the container and firm soil well around the root system. Water with a starter solution immediately after planting. Tomatoes respond to mulching because they require stable soil moisture. Black plastic mulch encourages early growth, while organic mulches are excellent for summer when applied 2-3 weeks after planting. Weeds compete with tomatoes for nutrients, water, and light. Use shallow cultivation near the plants to scrape away small weeds. A side-dressing of fertilizer when the first fruits on the plant are about the size of a walnut usually will improve yields and lengthen the harvest period. Cold nights early in the growth period or hot, dry, windy weather may cause blossom damage or blossom drop.

Tomatoes will ripen on or off the plant when the fruit are full sized and starting to show a slight tinge of color. Harvest early to reduce the chances of cracking, fruit rots, and other damage. Early harvest encourages additional production. Store ripening fruit at 55F degrees for maximum storage life or place them in a warmer location for quicker ripening. Red pigments do not form in temperatures of 95F degrees or above; therefore, deeper red color will result from ripening off the vine in summer heat.

If you’ve never planted tomatoes before, this is your year to get some started! They are easy to grow and you will be rewarded with juicy fruit throughout the season.
