Growing economical and environmentally sustainable yields of top quality maize remain a key requirement of growers be that for grain, silage or biogas production.   MGA Agronomy resources continue to provide technical advice aimed at growing great crops at a cost that ensures members maximise returns. MGA agronomy advice includes information on variety choice, seedbed preparation, weed control and harvest etc.  MGA agronomist advice is available free to members.

Harvesting maize in a difficult season

Monday, October 22, 2012

Maize in the drier and warmer eastern half of the country is generally average /good and harvest is now underway.  In the west a different story has developed, with many crops having struggled for a multitude of reasons from drilling.

With such a contrast in conditions and crop growth stage, working out the right date for harvest will be very difficult.  This task will be particularly difficult for growers with stunted crops, which may or may not have a viable cob. 

The good news is that the warmer weather of September has advanced crop maturity in all areas and even many of those with stunted crops now have cobs, which given time will lay down starch.  Ironically if the starch is laid down in these stunted crops, then overall maize quality could be good.  Yields will of course be down considerably.

The advice here is to 'wait as long as you dare' to ensure that the cobs have as much starch in as possible. That said, it cannot be forgotten that delaying harvest is not generally a good idea, as poor harvest conditions and frost can cause as much of a yield loss as is trying to be gained by delaying the harvest for maximum starch yield.

How much maize have I got?

Saturday, July 7, 2012

The cold and wet weather during the spring and summer has put many maize crops under pressure with concerns now being raised as to the yield and quality of the forage that will be harvested.  With options of home grown or even purchased wholecrop still available now is the time to work out where you stand.

 How much maize will I get?

This year’s maize yields are under threat due to the cold and wet conditions.  Early drilled maize, where it got away before the rain, has to a large extent stalled.  That drilled early into soils that have subsequently capped has struggled to breakthrough with plant populations severely hit in some cases.  Later drilled maize has avoided the early pitfalls but it is also struggling to grow in far from ideal conditions.  All the above will at best delay maize harvest but in many cases will also impact on crop yield. 

Maize not germinating - time to panic?
