Early Season Cotton Variety Response to Planting Dates

N. Buehring and G. Jones


 
ABSTRACT

Response to delayed planting for two early season maturing cotton varieties, DES 119 and Deltapine DP 50, were evaluated on a Catalpa silty clay loam and a Leeper sandy loam soil, 1991-93, at the North Mississippi Research and Extension Center. The environmental conditions differed all three years of the study.

Clay soil produced lower yield than sandy loam soil 2 of 3 years. Varieties showed similar responses on both soil types and planting dates except that DP 50 planted 6/15/91 on the silt loam soil and planted 4/27/92 on the clay soil produced higher yield than DES 119. Although the planting dates and growing environments varied widely from year to year, the data indicated that early maturing varieties in northeast Mississippi can be planted as late as about June 1 without adverse yield losses. These results indicate that for northeast Mississippi the early maturing varieties can be planted about 2 weeks later than were recommended for full-season varieties grown during the 1970's.
