Field Corn Field
Firing on lower leaves is still present – lack of nitrogen – and moving to higher leaves.
Tassels are breaking – no insects so it may be a weakness in the variety.
We looked at one ear. It is full, all kernels are formed and it has good size. Next week we will learn to calculate the expected yield from the number of kernels and rows.
Popcorn Field
Areas where there was standing water are now crusting. This would be a problem for germinating seeds, but not for growing plants. Buggy whipping is still present on a significant percentage of plants. There will be stunting of plant growth. It is also very visible the difference in plant height between those plants that were water stressed and those that were not. We will now need to watch for moths coming over from other fields.
We looked at signs of erosion – rilling and gullying. We talked about ways that farmers use to combat erosion. Unless there are continued heavy rains and runoff, this will not be a problem in this field.
Wheat Field now a Soybean Field
Soybeans are up and at the unileaf stage also called mid group 3 stage. It will be a race to see if we get full maturity and what kind of yield by October.
Hay Field
Not yet harvested for 2nd cutting.
Sweet Corn Field
Some varieties have begun to show tassels, but not showing ears. Because all the varieties were planted at the same time in close proximity there will be some cross-pollination. Because of all the moisture at the beginning, the roots of this crop have not grown deep. During these last days of hot, dry weather they are now showing the leaf curling signs of drought stress. They may need to be irrigated. Rule of Thumb for sweet corn; tassels and silks = 21 days.
Soybean Field
Soybeans are flowering and setting on bean pods. There are leaf hoppers present, possibly thrips (though we did not find any). We also found a green ‘clover’ worm or ‘inch’ type worm.
In the demonstration plots:
- Peanuts are beginning to peg.
- Hops can be harvested.
Community gardens
Green bean yellowing possibly from potassium deficiency.
