Pros And Cons Of Early Planting

Bill Pettigrew, USDA-ARS agronomist in Stoneville, Miss., has spent more than a decade studying cotton's optimum planting date.
"A consistent yield advantage could be gained from planting in the first half of April instead of in the traditional planting time of late April to early May," Pettigrew says. "The idea of this approach is to shift bloom closer to the first day of summer, the day with the longest period of sunlight, which synchronizes peak bloom with the availability of more sunlight to achieve maximum photosynthesis."
However, all of these studies were conducted with the use of irrigation. Interested in what effect the absence of irrigation would have, Pettigrew conducted a four-year study on the yield performance of irrigated versus dryland cotton planted early compared to normal planting time.
