A. S. Godoy, A. C. Godoy, G. A. Palomo, C. E. Garcia


The objective of this study was to determine the effects of different initial irrigation dates and different irrigation frequencies on yield and fiber quality. The experiment was conducted during 1992 at the Experimental Station of La Laguna. The experimental design was a split plot with four replications. Main plot was the initial irrigation dates with two levels: 1) 60 days after planting (DAP), and 2) 70 days after planting. The irrigation frequencies were the sub plots with three levels: 1) each 14 days, 2) each 21 days, and 3) each 28 days.

Results showed that the highest values in lint yield was found when initial irrigation was applied 60 or 70 DAP and then irrigated each 28 days. Fiber quality characteristics were not affected by any one of the treatments evaluated.
