Reflowering mungbeans

Take some time to decide what to do with a mungbean crop that has started to flower again after the recent rain.

Managing crops that have started to flower again

by Paul McIntosh

 

After a big warm, wet and humid week in North Queensland, I return back to a very wet  South Queensland and NSW with major and minor flooding and some very damp paddocks. Paddocks with a lot of summer crop and weeds in them. Valuable summer crops like mungbeans. The mungbean crop in the photo is typical of blocks that have a reasonable number of physiologically mature or black pods in them. However, with last week’s rain, the mungbean plants have decided to grow on and re-flower.

Now if those black pods were not already present, you would believe that to be a great idea, however given that the crop will grow on, this farm will have two distinct sets of bean pods. If it remains very dry, with no heavy dews, for the next four weeks, it may not matter too much. But, if there are any more rain events, the original black pods could well deteriorate in quality and grain can be lost through splitting, spouting or even mould.

So, what can be done?

The first decision for you and your agronomist is : which is your best crop? Is it this first crop of black pods with mature seeds in it, or is it the future crop that could result from the new flush of flowers on the very green mungbean bushes. Or, will you try to get both lots of grain in the bin?

Perhaps the week of wet weather has already spoilt your first crop of beans to the point of discard and you are forced into waiting for the next crop. This has certainly happened before, in other mungbean growing regions and in other years.

Mungbeans really getting a second lease on life after later season rain – reflowering and producing new pods as you can see in the photo.

This is not the worst thing in the world to occur, however decisions need to be made. Whilst it is still very wet on the ground take some time to discuss with your agronomist and decide what is best to do.

Compared to two or three weeks ago, we all now wish for no more rain on our cultivation paddocks at least.
