Abstract
The High Plains of Texas produces approximately 50 and 30% respectively, of the state's and nation's total cotton ( Gossypium hirsutum L.) lint production. The region's high elevation (> 3000 ft) frequently results in cool night temperatures during emergence, early growth, and maturation, resulting in inadequate emergence, population establishment, and seed and fiber maturation. This study was conducted to determine the effect of soil applied P and K on cotton emergence and yield and on subsequent cotton seed quality and yield from this seed on a soil testing high in available P and K. The soil used was a Pullman clay loam (fine, mixed, thermic Torrertic Paleustoll). Three rates of P (0, 29, 79 lb/acre) and three rates of K (0, 56, 149, lb/acre) were factorially applied to the same field plots in 1981 and 1982. No significant P × K interaction occurred for any measured parameter. Added P and K had no effect on cotton emergence or survival. Applied P had no influence on lint or seed yields, while K significantly increased lint yield both years, seed yield in 1982, and lint percentage in 1981. The K response possibly was associated with shortened growing seasons both years. Phosphorus and K applied during the seed production years had no effect on P or K concentrations of cotton seed, germination percentage, emergence rate index, or subsequent lint and seed yield and could not be recommended as a method of enhancing cotton seed quality.
