“…With respect to insect management, Scott et al (1994) noted an increase in bollworm [Helicoverpa zea (Boddie)] and tobacco budworm [Heliothis virescens (F.)] damage in narrow 76-cm rows compared to conventional 102-cm rows. Krob et al (2022) reported reduced adult thrips (Frankliniella spp.) density per plant as plant population increased.…”

Success stories of wide row cotton production have generated producer interest across the cotton belt. The objective of this study was to quantify the effect of row spacing on (1) cotton growth and development and (2) lint yield and fiber quality in Georgia. The cotton cultivar Deltapine DP 1646 (Bollgard 2 XtendFlex) (Bayer Crop Science, St. Luis, MO) was planted in 2021 and 2022 in Tifton, GA at row spacings of 91 cm, 122 cm, 152 cm, and 183 cm row spacings. Although canopy closure was delayed in wider row spacings compared to the 91 cm spacing, all other crop growth and development trends did not differ among row spacings. Similarly, row spacing had no effect on incidence of boll rot/ hard lock. The 91 cm row spacing yielded 1,734 kg lint ha−1. The 183 cm row spacing reduced yield 15% compared with the grower standard row spacing of 91 cm. Fiber quality parameters did not differ among row spacing treatments. Seed costs can be reduced in all wide row systems evaluated for cotton, and the 122 and 152 cm row spacings had similar yields to the 91 cm row spacing. However, Georgia growers produce peanuts (Arachis hypogea L.) and corn (Zea mays L.), the most common rotational crops for cotton producers, using a 91 cm row spacing. Consequently, the simplest transition to wide‐row production would be the 183 cm spacing, which incurred yield penalties in the current study. Thus, a 91 cm row spacing is still the most feasible option for Georgia cotton producers.This article is protected by copyright. All rights reserved
