DB—Lancaster Farming, Saturday, June 13,1981 NEWARK, Dela. - Corn in many fields is showing varying amounts of purple leaf color. “Where comparisons can be made, it’s clear that this purple coloring is associated with reduced growth,” says University of Delaware Extension agronomist William Mitchell. The key factor appears to be phosphorus deficiency, he says. The problem is occurring in some fields where the soil phosphorus level seems adequate, but where the soil pH is 6.2 to 6.4. “Cold weather is the reason most frequently given for purple com,” says the agronomist. “But tins spring we’ve expenenced an unusually warm April and normal temperatures for May. “Still, it’s likely that low soil temperatures are an important factor in the abnormal growth of com, since cold soil seriously limits root absorption of phosphorus. This being the case, we should expect these conditions to occur fairly regularly.” The problem can be solved by the use of a well-placed phosphorus fertilizer at planting. Some growers hesitate to return to this practice because it slows down the planting operation. Others argue systems from the concrete leader Feed quality is at its peak on the day you harvest.

A growing number of people, though, are saying that yield in creases will come and phosphorus in the planter is the way to go with this relatively expensive nutrient. Broadcast rates can be cut in half with banding, which increases recovery by at least 50 percent. Work under way at the University of Delaware Substation at Georgetown shows placement of starter fertilizer is extremely important, says Mitchell. Placement of fertilizer one-half inch or less from the seed has been effective in terms of plant growth. But in many cases with fertilizers such as DAP (diammonium phosphate), this caused about a 20- percent stand reduction. Moving the fertilizer band two inches from the seed produced the same growth response and eliminated all evidence of phosphorus deficiency without any stand reduction. When the fertilizer band was moved five inches from the seed, there was no visible growth response. Several nitrogen sources are being compared in Extension demonstrations at Georgetown. “Whereas DAP at 150 pounds per acre has given excellent results, Madison “System of Choice.” The logical concrete structure for every feed you grow.
