| Average frost date is October 21-30
28 degree freeze is usually between November 1-10
Thinking about doing it in the next day or two. Currently good moisture to get it going.

SE PA | Here in SE PA i've gotten an 8 bu corn yield bump planting Tillage RAdish Oct 9th the previous fall. A farmer in northern IN planted some the first week of Oct and also got an 8 bu corn yield bump 3 years ago. Yes, it's late but as far south as you are I'd go for it this week yet. It is borderline. Tillage Radish planted late will be harder to winter kill which is in your favor as well- probably 3-4 nights in the mid teens. |

Central Missouri | Steve, How thick do you plant them that late and are they rowed or drilled? Do you plant them with another cover crop? |
|

SE PA | You are in the last week of opportunity in Central Missouri. If you can precision plant you need sugar beet or small milo plates set to plant 4" in-row spacing. 15" rows is ideal and would give you a 4 lb per acre seeding rate. I'd suggest 8lbs drilled this late. A companion crop is great but i'd need to know what you are trying to accomplish, etc to make suggestions. Triticale, cereal rye, vetch are possibilities. I'd reduce the radish rate if planting a companion... |

SE IL and SW IN | So, how many fields planted that late got little or no response to get that occasional anecdotal yield increase. I am not against radishes as I have >800 acres planted to them, but I quit three weeks ago because it is TOO LATE to reliably expect a return on on my seed investment. Give it up, Steve and quit encouraging producers to make poor choices in an effort to build your business. |

Martinsville, Ohio | The point is Terry it doesn't take much of a radish to get a return on my farm. That is a personal decision I can't recommend to someone else unless they corner me. There is benefit in the gas exudates when they sprout or I wouldn't see the 12 bushels of wheat I get planting SRWW and radish in October.
It surely is too late to see those big radishes I have today I sowed in August. My excavator guy was so impressed he took some home. I told him there was taproot 50 inches deep, he said BS so we took the hoe and dug. The roots were right at 50 inches.
That is impressive but I don't need that much radish to get a yield increase on my farm. That is a personal decision one must learn himself.

| Ed, what do you think radishes are doing for the wheat to get the yield increase............ plant health? How many pounds of radish are you mixing with wheat? Thanks.

SE IL and SW IN | Ed,
I will repeat that I think that radishes are an incredible plant, but we are not talking about radishes planted in August or September here. It is October 12 with the soil temps in the 50s. My three week old radishes have their first true leaf this week. I will not deny that there might be a strategy where radishes planted today might give some benefits, but the odds of a producer getting a return on his seed and labor is greatly reduced, especially for the cover crop novice. You and I are adults and know the risk and rewards for pushing the too late date, and I have done it on thousands of acres and am still not sure where it is, but I will repeat that it is irresponsible to recommend this or any high risk strategy to the novice user. |

chestertown, md | 3-4 lbs/ac=about $10ac.
i've "wasted" that many times.......
still a dice roll on temps. |

Martinsville, Ohio | Never once did I think that was a waste but Terry could be right. I understand his message, that of sales beyond self and making recommendations for others.
We are discussing ideas and people want input. I would waste my money on the attempt, I would not recommend others to do what I do.
Rich, 1-2 lbs per ac seems to get the effect. When the wheat comes out of dormancy, mine has a different color, a darker blue green purplish tint to it and I don't know what all happens biologically and chemically to make that happen. I have seen it time and time again.
Normally my radishes don't die until Christmas but each year is different. If they stay alive for 30 days they have a good chance of improving my soil biology and perhaps fertility a little.

SE PA | I have not seen a non paying response yet in research but then again we have not reached the "wall" yet. this year i plan to plant them as late as Oct 20 to see. Have you planted them late on your farm in replicated research? Since we get a wheat response about 75% of the time planted in Oct, why might that not possibly translate to other crops? We need more tests to validate the late planting of any cover crop. It does seem that mixes make the planting window longer. I try to make farmers aware of the risk involved in any suggestions that are made. We still have a lot to learn. |

| Ed,
I found one in my corn field 2 wks ago that was planted after the wheat, LAST year. Evidently it didn't winter kill. Of course our winter was very mild last year. Unfortunately I didn't have my camera with me that day.

South East South Dakota/winters Tucson, AZ | I am finishing planting radishes tomorrow. I am think i am further north than most of you. Have not had any rain and had been waiting. We are forecast to have 1/2 inch satuday. And warm days for the next 10 so they might sprout. I am planting them with my kinze split planter.

swohio | This is what I want to see, poeple doing things outside the box. Ezrydr is doing something I would not think would work, yet what if it does? I saw the same thing when I started notilling long ago, IT WON"T WORK. Glad I kept working at it. To me cover crops are alot like notill was. It may not be for everybody, but I do know that it works. I'am glad that farmers want to try differant approches, it is the only way to learn. |

Have you planted them late on your farm in replicated research?
Yes I have and when we did it last year, we did not even try to collect data on the radishes planted on October 8, because there was almost nothing to measure. The PIC below taken Dec 1 is of our oat/radish mixes , the best we measured planted October 1. These radishes captured less that 5# N/acre, and are at the minimum growth for a return in the following corn crop in my opinion. I have no experience with radish in wheat.
Over the last four years I have added radishes to hundreds of acres of proven cover crop strategies and for my money will consider October 1 my latest planting date here in SE IL. I will not say that benefits cannot be achieved, just that the risk vs reward increases quickly at some point.

SE PA | Terry,
do you mean there was no corn yield to measure? I assume so with the drought. But you never know though without measuring. I've done hundreds of plots and have come to the conclusion that just you can't make assumptions without weighing-you can't see an 8 bu difference. I understand risk vs reward but until we get more on-farm data of the effects of subsequent cash crop yields after any cover crop, we still don't know when the general end planting date should be. I think there may be a biological stimulation effect that triggers on germination of a cover crop but that is just a theory at this time. This is a great discussion and has caused me to expand my late planting of Tillage Radish test to other cover crop mixes as well which i plan to seed early next week. I'll have a control with no covers to compare- 1,500 ft X 3 reps of each treatment. |

SE IL and SW IN | There were NO RADISHES TO MEASURE. The largest had one true leaf.
I think YOU as the beneficiary of proceeds derived from the sale of Tillage Radishes should plant radishes and other cover crops past the too late and other out of the box situations. You should even invest in some third party research on the topic. Where we part ways is where you still encourage producers to continue risky behavior (recommend 8# of radishes below in a risky situation) and even though there will be countless failures (and I have had hundreds of acres of radishes fail because of late planting, but still use and recommend them when used correctly) you will only tell us about John Smith three states away who had an 8 bushel yield increase. |

Northwest Ohio | Call me crazy but I am seeding an annual rygrass and tillage radish mix today, I want to see what happens. If it fails, it fails, I'll take the loss. I am in Northwest Ohio, near Lake Erie, where the Lake keeps us a little warmer a little longer. |

Martinsville, Ohio | I am getting so I like to see those chosen volunteers I planted! Nothing like a big stand of corn in soybeans, though, which I do not want!

Martinsville, Ohio | I agree, think outside the box. The more I seed the better I see my soils perform. I hope your cover does a good job for you, even "this late."

|
SE PA | I attempted to outline the risks and mention straight forward observations as i know them so the original poster, corn on corn, could make his own decision. There is so much i don't know yet about cover crops that i can't make blanket claims. |

Clark SD | Bob, if you care to can you post once and a while how the radishes are doing or not doing?
Mike |
|
| |
|
Clark SD | At what is the minimum temperature that the radish will germinate at?
Also have you or someone else tried dormant seeding of radishes? |
|
| |
|
Martinsville, Ohio | More temperature than wheat Mike. The wheat I planted is up but the radish is not. Wheat 39 degrees? Radish maybe 50 or 40's?
Ed |
|
| |
|
SE PA | I don't know but i'm planning on putting some in yet today or Monday in a plot with cereal rye and triticale. Will observe emergence. I should get some soil temperature monitors like you have!
I've planted Tillage Radish in Nov, Dec and Jan. They emerged early March. It is not uncommon for radish seed planted in dry conditions in the fall to not germinate and emerge in the spring- the buggers are tough. I'm looking at dormant seeding as a possible opportunity in years when you can get in the ground. All my research is geared to subsequent crop yields so we'll try and get some numbers to see if this practice pays. I assume it may some years and other years may not. |

South East South Dakota/winters Tucson, AZ | Radish/turnip planting update. Got done planting friday night. Butthe rain did not materialize and the forecast for the next 10 days is warm and no rain. So i may have wasted seed and time. Not the first time but sure seems i do it more as i try new ideas and ways to farm. Since the research ag schools are not doing any kind of outside the box research it is up to us. Now hoping they come up next spring. |

S.E. Iowa | I agree with the out of the box statement. We need more people like Joel Gruver. The more I learn the less I know. I used to grow soybeans for seed and the president of the company said some of the best plant breeders did not go to college. He went on to say, they did things teachers said couldnt be done. When rounds up beans came out I was at the farm progress show and asked a rep there "if you really want to help come out with 24D and atriazine resistant beans" he said it couldnt be done. |

How late can I plant a Tillage Radish cover crop?
