Nitrogen fertilization of ultra-narrow row cotton.

Ultra-narrow row (UNR) cotton (Gossypium hirsutum L.) represents a unique development in cotton production for Arkansas. It is a drill-planted, stripper-harvested, nonirrigated, low-input production system designed to maximize economic returns. Research that provides information on production parameters is scant. Optimum nitrogen (N) fertilization rates and how UNR cotton utilizes N are unknown. The objective of this pilot study was to gain experience with UNR cotton production and to determine how UNR cotton would respond to N fertilization.
