“…However, we found that the most combinations had a slight earliness to starting the first flower (Table 3). These results agree with Batista et al (2010) that submitted cotton plants to different methods of irrigation and found that in water stress condition an earlier blooming took place in genotypes. As to Gowda and Hedge (1986), this earliness is often associated to reduction of plant cycle, and it is a desirable feature, especially in environments prone to "indian summer" (veranicos) or water rainfall irregularities.…”

“…Reproductive phase are quite dependent on water and fertilization supplements. According to Batista et al (2010), water suppression in cotton plants for 23 days causes reduction in plant height, fiber growth, bud and boll numbers, although root system length is increased as a response to dry condition.…”

“…Fertigation with 100% of reuse water also supplied 26.12 kg ha -1 of P in the first cycle and 29.7 kg ha -1 in the second cycle. These values are below the 52 kg ha -1 found by Batista et al (2010), for the maximum yield of the crop. In turn, the supply of K was equal to 91.42 and 103.8 kg ha -1 in the first and second cycles, respectively, which are slightly below the 121 kg ha -1 recommended by Bernardi et al (2009), for maximum cotton yield.…”

Water reuse is an important practice in water resource management especially in arid and semi-arid areas. The objective was to evaluate the mineral composition and boll weight of upland cotton (cultivar BRS 335) plants under fertigation with domestic sewage effluent and phosphate fertilization. An experiment was carried out using randomized block design in a 3 × 2 factorial scheme with six repetitions. Cotton plants were fertigated with three fertigation solutions containing domestic sewage effluent (RW) and supply water (SW) in the proportions of 100% SW - T1, 50% SW + 50% RW - T2 and 100% RW - T3, and two phosphate fertilizer managements (with and without phosphate fertilization at pre-planting). Macronutrient and micronutrient concentrations in the shoots and boll weight were measured and evaluated. Fertigation utilizing reuse water is able to supply both water and part of the nutritional demand of cotton plants. Calcium, copper, iron and zinc concentrations in cotton leaves were below the optimum range for the crop. Reuse water did not meet the total requirements of Ca, Cu, Fe and Zn of cotton, so complementary mineral supplementation with these nutrients is recommended for the crop to obtain high yield.

“…Baldo et al (2009) evaluated cotton genotypes submitted to 45 days of water suppression and observed severe reduction on plant height, stem diameter, number of leaves, number of leaves and reduction of 25% on boll yield, as well. Batista et al (2010) corroborated these results when evaluated cotton genotypes submitted to 23 days of water suppression. The authors also observed losses on fiber quality, although elongation on root system was verified in tolerant genotypes, as a defense response to desiccation.…”

The aim of this study was to characterize cotton cultivars based on growth data and on antioxidant enzymes activity, in order to identify better-adapted cultivars to water-stress conditions. Nine genotypes were submitted to 7 days of water suppression starting at 45 days after seedling emergence (phase R1). The essay was carried out in greenhouse conditions, where plants were grown in 5 L vases filled with sandy soil previously fertilized as recommended for the crop. A completely randomized experimental design adopted in a 9×2 (genotypes × water treatment) factorial scheme and 4 replications. Cultivar classifications were performed by multivariate analysis, using canonical variable and UPGMA cluster analysis. The following growth traits were recorded: Plant height, leaf stalk diameter, number of leaves and root length and weight. Antioxidative activities (SOD, CAT and APX) were also tested by spectrophotometry. Water stress affected all genotypes with different response level. The genotypes adapted to semiarid environment showed better capacity to grow under water limitation, and also better performance of antioxidative enzymes in order to avoid cellular damages. BRS 286, CNPA 7MH and CNPA 5M were better adapted to drought period and regarded as the best cultivars to use in cotton breeding aiming tolerance to water stress.
