Abstract
Experiments were conducted at the Tennessee Valley Substation (TVS), Belle Mina, AL and Wiregrass Substation (WGS), Headland, AL in 1998 to compare weed control and Pix® requirements for UNR and conventional cotton. Both tests were planted in notill systems using Paymaster 1220 BG, RR. The ultra-narrow row cotton was planted on 7.5-in. rows with a grain drill while the row cotton was planted on 40 in. (TVS) and 36-in. (WGS) rows using a conventional planter. Treatments were arranged as a 3x2x2 factorial in a Randomized Complete Block experimental design. The three factors studied consisted of row spacing, weed control, and Pix® level. The two levels of weed control were a preemergence + postemergence system compared to a postemergence only herbicide system. The two levels of Pix® applications were 4 oz. and 8 oz. on UNR cotton and 0 oz. and 4 oz. on conventional cotton, respectively. Pix® was applied on an as needed basis. Data gathered on the two experiments consisted of visual weed ratings, crop injury ratings, plant stand counts, plant height and node counts, boll counts, and seed cotton yield. The gin turnouts were 36% and 39% for the conventional cotton at TVS and WGS while the UNR cotton had turnouts of 31% at both sites.
