EC North Dakota | Yes, but black layer is more of a brown layer. There may be some debate as to when that layer is actually done/defined.
Some of the irrigated guys believe you can can gain yield beyond brown layer. Not if the corn is actually physiologically mature, which is most guys definition of black layered. We have seen yield gain to watering after brown layer, so I think that's where the argument comes from. Usually the yield gain isn't worth the risk of making the field too wet for harvest.
Test weight changes, if that matters to you and harvest losses change but the corn plant does not continue to fill the kernel after BL. | |
