New Mzuri rehab subcast

Clive · Aug 1, 2015

Cut the 750a drilled crop in this patch but have stopped now as the Rehab established crop is still quite green and maybe a week of harvest still

750a crop has done well but I wonder if this extended growing season will see the Rehab do better still ??

Can't what for the weigh in!!

That is somewhat strange isn't it? I would have thought the wider rows and less plants per meter would let the crop dry out more easily and be fit sooner? It is what I usually see with cereals that are drilled in 12,5 cm rows rather than say a Claydon.

Or maybe it's rooted better so has held on to moisture longer ?

Certainly interesting difference given that all other dates / inputs are identical other than the establishment method

Yes that is a very fair point especially during this dry spring? Roots went down deeper and pulled up more moisture. Question is now, did they put that growth into more greenery or into yield. Did the crop look any taller?

Look back through the pics in the thread - to begin the rehab always looked the stronger and more vigorous crop to my eye but then the 750a caught up and there was little (if anything) to choose by late spring

It would be interesting if we did see a significant yield difference here wouldn't it

TelesnaAg · Aug 3, 2015

Clive could you post oil content comparison and if the seed is noticeably larger..given its hanging on a bit ...if it's not to much trouble...

If the yield is the same which is the greater profit?...or is there bugger all in it?...for me the rehab look like it would be great for stubbles that didntbgomas planned and also I would like to do beans on rows to see if it's a better option..also the option of inter rowing from year to year for disease etc...

Very interesting..

just moved to cut this tonight, should be done by midnight and will have some results tomorrow to post - from what the combine driver tells me it could be interesting

place your bets ??

Mzuri by a short head....higher oil...

this so exciting!

So the two crops, the Mzuri ahead with green in the Autumn - is it setting roots at this time and is the 750a festering. I think that the bigger green was probably from shallow rooting through easier earth. The 750a was struggling putting roots down through all equally hard stuff.
Come any dry the Mzuri hadn't got the tap roots down because it hadn't had to and the 750a had so took off.
The important question is where and when is the crop made - is it pollination or filling the seed, I expect that the pollen could have been in the cold period and to be honest I haven't read what is normal, but I suspect bad and the earlier crop [Mzuri] would suffer. I expect that you could pollinate a lot of seeds and then they are dropped because the plant couldn't support all of them going into drought.

My prediction is that the dry period the Mzuri struggled and was probably not pollinated and even if it was probably dropped the seed. But this was light land and a slightly weird year.

So Mzuri lower yield higher oil. 750a higher yield lower oil. Both neither particularly profitable apart from being a good break for wheat.

so here are the yield maps (weighbridge corrected so very accurate) the area inside the red box was the Rehab area the rest was 750a drilled.

Ultimately very little difference, the rehab area was starting to lodge and there is evidence of some seed on the floor, maybe the wider rows not holding the crop up so well ? or maybe the crop was a bit heavier so didnt weather so well ?

Although little difference and the 750a has achieved higher yields in the best places the rehab area does seem more consistent

overall yield on this block was 1..7t/ac - nothing spectacular but given the low inputs spend it returns a positive nett margin even at today's prices

will get oil results from wieghbridge later

so in short I don't think we proved much really !!!

Clive · Aug 10, 2015

nett margin map of that area, profitable OSR is possible even if its no 2t/ac plus crop

- as I don't have a costing for the rehab establishment I have used same cost as the 750 - in reality I guess the rehab would cost more to operate than a disc drill ?

Doesnt it show that it doesnt make much difference how you established it and therefore cheapest / quickest is best

maybe ! draw whatever you want from it, all I have done is present the facts

TelesnaAg · Aug 10, 2015

Thanks so much Clive...efforts appreciated..

For me it shows that if the wider rows are needed in the event stubbles not going well or maybe a paddock suffering compaction issues where the rehab is a viable option with no yield penalty of any significance...all though one year is not much to hang hat on but good to see none the less.

In Australia where we don't have the OSR in the ground anywhere near as long as you guys I wonder if you can use longer season varieties with the rehab as it gets going quicker...the same trial over here would be interesting...

Cheers...

Niels · Aug 11, 2015

Thank you for the information Clive. It seems the middle of the field delivers some good yields. It's mainly the headlands and a few other bits that pull the field average down. Is this due to pigeon damage or compaction, tree shading, soil type etc?

Teejay · Aug 13, 2015

It would be interesting to see if the rehab area could be picked out in the following crop.

RBM · Aug 16, 2015

Just caught up on this, nice work Clive, great to share your experiences that are more relevant as they are farm scale trials and bust some myths at the same time!

trees, pigeons , rabbits in a few areas - this also only 2 year zero-till land as it was the last field potatoes were grown on here and was a right mess and is only just starting to get half decent structure now, especially headlands

You best get a mzuri imported Ant to get the trial underway.
