Evaluation of Ultra Narrow Row Cotton in Mexico

A. S. Godoy, M. E. Castro and C. E. A. Garcia


 
ABSTRACT

This study was designed to determine the effects of number of irrigations and plant population on earliness, lint yield and fiber properties of Fiber Max 819 cotton variety. The field evaluation was carried out in 2000 at “La Laguna” Experiment Station at Matamoros, Coahuila, Mexico. The experimental design was a split-plot with three irrigation treatments as the main plots and four plant population treatments as the sub-plots. Earliness was measured as the percentage of crop harvested at the first picking (PCH-1). Lint yield (kg/ha) was determined by harvesting two center rows of each plot. A 20-boll sample of seedcotton was hand picked prior to harvest and lint percentage, and fiber properties were determined from these samples. The value of PCH-1 of cotton irrigated once was the highest (86%). The highest lint cotton yield, independently of plant population, was obtained by the treatment with three irrigations. On the other hand, the highest lint cotton yield was obtained with a plant population of 120,000 and 200,000 plants per ha. The lowest value of fiber length (27.2 mm) was obtained when Fiber Max 819 cotton variety was irrigated once. The highest value of fiber resistance (92,000 pounds per square inch) was obtained for Fiber Max cotton variety with one post planting irrigation.
