Abstract: Resumo -O objetivo deste trabalho foi determinar a época apropriada para a realização da poda apical em algodoeiro. O trabalho foi realizado durante as safras de 2008 e 2009 (maio a novembro) em delineamento de blocos ao acaso, em dois ambientes, com as variedades: BRS 201, de fibra branca, e BRS Rubi, BRS Safira e BRS Verde, de fibra colorida, em Paudalho, PE; e BRS 201 e BRS Rubi, em Surubim, PE. A poda apical consistiu na retirada dos ápices das plantas com estruturas vegetativas e reprodutivas, em duas ida… Show more

“…Although clipping developing fruiting bodies might be expected to reduce harvestable lint, their removal after physiological cutout (Guinn, 1986;Cothren, 1999) does not affect yield (Ritchie et al, 2007;Neves et al, 2010). Four cotton varieties, each with 50% of bolls clipped at the hard stage or at the beginning of opening, produced similar yields as control plants that were not clipped (Neves et al, 2010).…”

Four cotton varieties, each with 50% of bolls clipped at the hard stage or at the beginning of opening, produced similar yields as control plants that were not clipped (Neves et al, 2010). By clipping fruiting bodies on terminals, any energy being distributed by the plant to them may be diverted toward maturation of the older, harvestable bolls (Kim & Oosterhuis, 1998), leading to greater synchrony of boll opening and improved quantity and quality of fiber (Deng et al, 1991;Bednarz & Roberts, 2001;Brown et al, 2001).…”

“…Upon squares, they feed and oviposit [ 2 , 3 , 4 ]. Oviposition in these cotton squares induces abscission before bolls develop, causing direct yield loss [ 5 , 6 ]. Besides natural shedding, fallen attacked squares allow larvae and pupae to fulfill development in their interior, resulting in faster boll weevil population growth [ 7 ].…”

“…Control of this pest is usually done with chemicals that are not always effective. Furthermore, they also kill the natural enemies of the boll weevil (BASTOS et al, 2005;NEVES et al, 2010).…”
