Abstract
Field experiments in two successive seasons, at the Agricultural Research Center (ARC), Giza, Egypt, were conducted to study the effects of phosphorus fertilization (addition at rates of 44 or 74 kg of P 2 O 5 /ha) and foliar application of zinc (applied at 0.0 or 40 ppm of Zn at two times: 75 and 90 days after planting) and calcium (applied at 0.0, 20, 40, or 60 ppm of Ca at two times: 80 and 95 days after planting) on growth, mineral uptake, yield components, yield, and fiber properties of the Egyptian cotton cultivar Giza 75. Dry matter yield of cotton plants (shoots), 105 days after sowing, phosphorus, calcium, and zinc uptake/plant, number of opened bolls/plant, boll weight, seed index, lint index, seed cotton yield/plant, seed cotton and lint yield/ha, and earliness of harvest increased with increasing phosphorus rate and application of Zn and Ca. Treatments generally had no significant effect on lint percentage and fiber properties, except in season I, when Micronaire reading and flat bundle strength increased by addition of high phosphorus rate and 2.5 and 50.0% span length increased by application of Ca at 40 and 60 ppm compared to control. Keywords: Phosphorus; zinc; calcium; cotton yield; fiber properties
