Pod Maturity Images From Lewiston-Woodville
Below are images from pod blasting yesterday (September 5) at Lewiston-Woodville.
Sampling all planting dates again would be advised (May 4 and 16 late next week). Keep in mind that a week on the early side of maturity can decrease yields and grades significantly.
Data in the table below show yields 540 pounds/acre lower when dug early compared with the second digging date. Waiting a week past the second date helps. But the increase is only a 100 pounds/acre. However, ELK goes up about 4 more points with each delay (dig 1 to dig 2 to dig 3) and TSMK goes up 3 points with each delay.
Not considering grades, at $0.27/pound ($540/ton), 540 pounds are worth $145/acre. This is the economic value of at least 2 of the 3 pest management bills a farmer has (weeds, disease, insects). But I know patience can be hard to come by and folks with lots of acres have to get started so they can get finished. This is why adequate digging and harvesting equipment is essential.
