Comparisons of Petiole Nitrogen Content for PIX Treatments

Joe Townsend and John McKee


 
ABSTRACT

A test was conducted during the 1999 growing season on Westside farms of Friars Point, Mississippi, by Precision Cotton Testing. The test was an attempt to measure the relative efficacy of Pix Plus and BAS 130-01 in relation to plant growth and yield of cotton as compared to a Pix standard treatment. There were 12 replicates of 12 row plots approximately 700 feet long. Pix, Pix Plus, and BAS 130-01 were applied three times to the cotton beginning at the 11th main stem node. Equal amounts of each product were applied to reach a combined total of 36.4 ounces per acre. The cotton was measured for plant height three times. The height at the third measurement was Pix 36.94 inches, Pix Plus 36.14 inches, and the BAS 130-01 at 38.72 inches. The results of plant sap nitrate analysis showed an average across 6 sampling dates of 5,753.5 PPM nitrate in the Pix standard, 7,800 PPM in the Pix Plus, and 6,878 PPM in the BAS 130-01 treatment. Pix Plus and BAS 130-01 both showing more stored nitrate than the Pix standard. Yield was taken with a cotton yield monitor, and yield maps made. Although somewhat inconclusive the BAS 130-01, and the Pix Plus both out yielded the Pix standard.
