Sparse rainfall occurred over the state last week. Amounts reported were from none to 1.5 inches. Drought stress was evident in corn and soybean. Some pastures in southern Iowa are dry and brown. Corn growth stages range from VT-R1.
Brown silks are present on many corn plants.
As much as 40-50 percent of the crop is tasseling in west central and north central counties. Soybean growth stages range from R1-R3. Potassium and nitrogen deficiencies were reported in corn, the latter causing whitening of leaf edges or dark green foliage. Cupped leaves were common in soybean throughout Iowa. Some beans are yellow.
