Comparing the Last Effective Boll Populations in Ultra-narrow-row and Conventional Cotton
نویسندگان
چکیده
Identification of the last effective boll population allows informed decisions for termination of insecticide and application of harvest aids. However, the current COTMAN cutout reference, i.e., NAWF=5 (Oosterhuis et al., 1999), may need to be changed for ultra-narrow-row (UNR) cotton. This study is part of a multi-state project which has an overall objective of determining the main-stem node number of the last effective boll population in UNR cotton grown in a range of typical field environments, compared to wide-row cotton in those same environments. This report describes the study conducted in northeast Arkansas in 2001.

Comparing the Last Effective Boll Populations in UNR and Conventional Cotton
Identification of the last effective boll population allows informed decisions for termination of insecticide and application of harvest aids. However, the current COTMAN cutout reference (i.e., NAWF=5) indicates physiological cutout (Oosterhuis et al., 1999) may need to be changed for ultra-narrow-row (UNR) cotton. This study is part of a multi-state project the overall objective of which is t...

To investigation the yield and yield component of cotton (Gossypium hirsutum L.) planted in conventional and ultra narrow row spacings, in competition with velvetleaf (Abutilon theophrasti Medic.) an experiment was conducted in a completely randomized block design with split plot arrangement of treatments, with three replications at Experimental Station of Gorgan University of Agricultural Scie...
متن کاملNitrogen Fertilization of Ultra-Narrow-Row Cotton: Final Report1
Recent developments in cotton (Gossypium hirsutum L.) production technology in the Delta include drill planting cotton in an ultra-narrow-row (UNR) production system. Ultra-narrow-row cotton is a low-input production system designed to maximize economic returns. The premise is that UNR cotton will be lower yielding, but the reduction in input costs will result in a larger profit margin. Researc...

Determining environment – associated alterations in grain yield is important in yield assessment under drought stress. Therefore this study was carried out to determine the correlation coefficients and direct and indirect effects of effective components on yield in four drought - tolerant and susceptible cotton cultivars. Cotton cultivars were considered as sub plots and 3 levels of irrigation ...

Flat and cylindrical adhesive boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), pheromone traps captured significantly more (P < or = 0.05) boll weevils than the Hercon (Hercon Environmental, Emigsville, PA) trap during the late cotton-growing season, and larger adhesive areas were associated with higher captures; a flat plywood board collected the most boll weevils b...
