Abstract:
This article reports the estimated relationships between fiber properties of the Acala 4-42 cultivar and N- and P-fertilizers and irrigation. Increasing water rates in the range of 4200-7200 m3/ha weakened the tensile strength of the fibers and increased their fineness; the regression of maturity, length and uniformity ratio was curvilinear: positive on initial rates and negative on those exceeding 5800 m3/ha. N-fertilizer favorably affected all fiber properties determined: fineness and upper quartile length throughout the rate range tested but strength, mean length and uniformity ratio only up to 250-500 kg ammonium sulfate per ha. The most favorable effect of P-fertilizer was in considerably increasing the length uniformity ratio; it also increased length and fineness but suppressed the maturity index. © 1970 Dr. W. Junk N.
