Results: Application of destructed Spirulina increased the plant leaf area, chlorophyll a, b, carotenoids and gibberellin contents, plant height, fruiting branches, open bolls/plant, seed cotton yield and seed index after ginning, fiber length, fineness (Micronair) and strength (Pressely) comparing to the corresponding non-sprayed plants. Urea at 192 kg N/ha along with destructed Spirulina exhibited superiority as enhancers of plant growth, yield and fiber qualities. Conclusion: The dual N/Spirulina combination expressed enhanced cotton growth, yield and qualities of fibers. The tested fertilization strategy is promising for enhanced cotton production economy. Keywords: Cotton; fiber length; fineness and strength
