Death comes to us all. Life's but a walking shadow | For corn, yield is a function of the number of kernals per acre. Plants per acre x ears per plant x kernel rows x row length. Number of kernel rows is determined between V5 & V7. Maximum number of kernels per row (ear length) is determined at V9-V(tassel). Actual number of kernels (pollinated & survive blister stage) is set during V(tassel) to R3. Kernel filling & weight during R5. With this in mind, you should be able to begin to evaluate yield potential by determining the number of kernel rows at tasseling because the number of kernel rows is fixed by then. It would be interesting for some of those producers who experienced early season dry to find out how many 14, 16 or 18 kernel row ears they have. Some of my corn is just reached the tassel stage and if I get chance I'll check. We've had severe moisture stress almost since planting. |
