Cotton planted on 15 inch row spacing is a new innovative idea that has come about in the past few years. This new idea has brought many questions to the cotton industry because growers have had to change some of there cotton production strategies in order to grow cotton on 15 inch rows. There is very little known in the cotton industry of what management practices best fit the close row spacing of the cotton. One of the questions raised is: What nitrogen rate will give controllable growth and is the most economical efficient in production of 15 inch cotton? A field experiment was conducted in 2005 at Upper Coastal Plains Research Station, Rocky Mount, NC to determine these nitrogen rates. Stoneville 5599 BG/ RR was planted on 15 inch row spacing using a six row John Deere MaxEmerge XP planter. Treatments consisted of nitrogen applications of 0, 29.94, 59.88, 89.80, 119.74, 149.68, and 179.63 kg/ha. Treatments were arranged in a randomized complete block design replicated four times. Data taken from this experiment consisted of leaf and petiole samples to determine nitrogen uptake in the plants, percent defoliation, percent desiccation, and regrowth ratings 14 days after defoliation, and final heights, nodes, and internode lengths at harvest. Ten uniform plants will be cut from each treatment to be box mapped prior to harvest. The purpose of box mapping will be to group bolls into node zones 3-5, 6-10, 11-15, and 16-20 by position with all boll weights recorded as grams of seed cotton to look for differences in boll weights by position. The four middle rows of the six row plots will be spindle picked using a four row John Deere 9910 cotton picker equipped with PRO-12 VRS Row Units and seed cotton samples will be taken to be ginned for lint turnout and fiber quality will be determined by high volume instrument analysis. Data will be analyzed with the general linear model in SAS and means will be separated according to Fisher's Protected LSD at Ą=0.05. All 2005 data is still pending.
