“…These seed cotton yield and fiber yield reductions are similar to those reported (El-Fouly et al, 1971;Marur, 1991;Cook and El-Zik, 1993;Rajamani, 1994;Pettigrew, 2004b;Bölek, 2007;Alishah and Ahmadikhah, 2009). Some researchers revealed that water stress at different growing stage reduced cotton yield, with the greatest effect at the flowering and fruiting stages (Luz et al, 1997).…”

The primary objective of this study was to determine the effect of water stress and non-stress conditions on cotton yield and fiber quality properties. A two-year field study was carried out at the Southeastern Anatolia Agricultural Research Institute (SAARI), in 2009 and 2010, with the aim of evaluating 12 cotton genotypes for yield and fiber quality properties under irrigated and water stress conditions. The experiment was laid out as a randomized split block design (RSBD) with four replications. Significant differences were observed among genotypes and water treatments for seed cotton yield, fiber yield, ginning percentage and all fiber quality properties except fiber uniformity. Yield differences among genotypes under water stress and non-stress conditions were higher during the first season. In both years, SER-18 and Stoneville 468 cotton genotypes produced higher yield under water stress conditions, while Stoneville 468 produced higher yield under well-irrigated conditions. The results during the two years indicated that seed cotton yield decreased (48.04%) and fiber yield decreased (49.41%), due to water stress. Ginning percentage and fiber quality properties were also negatively affected by water stress treatment. Fiber length, fiber strength, fiber fineness and fiber elongation were decreased, while fiber uniformity was not affected by water stress treatment.

“…According to Reddell, Prochaska and Cudrak (1987), the onsetof the flowering period is most sensitive to water deficit in cotton, while for Orgaz, Mateos and Fereres (1992), the most sensitive period occurs during the peak of flowering. On the other hand, numerous studies, such as Cook and El-Zik (1993), showed that the period most sensitive period to water deficitis just after flowering, when the plants were plenty of fruits.…”

Cotton Response to Water Deficits at Different Growth Stages

-Water deficit at certain cotton growth stages can cause severe damage to crop development, affecting physiological processes and reducing reproductive structures, with consequent yield losses. The objective of this study was to evaluate the response of cotton cultivars under water deficit applied at different stages of the crop cycle. We compared the number of bolls per meter, cotton yield, and water use efficiency for eight different cotton cultivars under a water deficit of 15 days. We selected the following growth stages: Emergence (EM), First Square (FS), First Flower (FL), Peak Bloom (PB), and First Open Boll (FOB). The control treatment was irrigated with 100% ETc. The experiment was conducted in Apodi, RN State of Brazil, semiarid region, using a sprinkler irrigation system. The number of bolls per meter, cotton yield, and water use efficiency were influenced by the interaction of cultivars x deficit periods. Lowest values were observed for water suppression in the FL and PB stages. When the water deficit was imposed in the initial stages of growth (EM to FS) or after the FOB stage, the cotton yield reduction was not significant. At the same stage and water deficit, the behavior of the different cultivars was similar. Producers are urged to take this information into account when developing irrigation schemes for cotton crops, thereby avoiding water deficits during the most critical periods of the crop cycle.Key words: Irrigation Management.

RESPOSTA DO ALGODOEIRO AO DÉFICIT HÍDRICO EM DIFERENTES FASES DE CRESCIMENTORESUMO -O déficit hídrico em determinadas fases do ciclo de cultivo do algodoeiro pode causar severos danos, afetando as estruturas reprodutivas, acarretando perda na produtividade. O objetivo deste trabalho foi avaliar a resposta de cultivares de algodoeiro submetidas ao déficit hídrico em diferentes fases do ciclo de cultivo. Comparou-se o número de capulhos por metro, a produtividade e a eficiência no uso da água em oito cultivares de algodoeiro herbáceo, submetidas a déficit hídrico por 15 dias nos estádios: emergência, emissão do primeiro botão floral, emissão da primeira flor, emissão da primeira maçã, abertura do primeiro capulho e a testemunha irrigada com 100% da ETc. O experimento foi instalado no município de Apodi-RN, região Semiárida do Nordeste, em área irrigada por aspersão. O número de capulhos por metro, a produtividade de algodão em caroço e a eficiência de uso da água foram influenciadas pela interação cultivares x déficit hídrico. Os piores resultados foram observados para o déficit hídrico de 15 dias após a emissão da primeira maçã e da primeira flor. Quando o déficit hídrico foi imposto nas fases de crescimento inicial, após a emissão do primeiro botão floral e após a abertura do primeiro capulho, a perda de produtividade não foi significativa. Dentro de um mesmo período de déficit hídrico, as cultivares se comportaram de maneira similar. Os produtores devem levar essa informação em consideração para ouso da irrigação suplementar e para progr...

“…In contrast, the most sensitive phase to water stress is during cotton boll filling stage (peak bloom), in which water deficit was imposed (Cock et al, 1993;Gwathmey et al, 2011;Snowden et al, 2014). So, the sample collection by SS method in this phase resulted in an underestimation of the results, probably because the sampling may occurred in the area of the plant with the most affected bolls by water stress (Figure 3).…”

The quality of cotton fibers in Brazil has been studied. This was done by studying the fiber samples obtained from bolls removed from the middle third of the plants. These fiber samples are referred to as "standard sample". This way to collect fiber data requires lots of labor, and may disguise the results obtained in experimental appraisals, due to human errors in gathering boll. Besides, cotton yield and quality is influenced by water availability, especially during abiotic tests with water deficit, in which, fiber quality samples may be affected by boll position. Thus, the objective of this study was to evaluate the influence of sampling method on the technological characteristics of cotton fibers, in irrigated and water stress tests at different stages of the crop cycle. Two methods were made to collect cotton fiber. The first method was the standard sample and the second way was gathering sample of bolls in randomized position, through all experimental plot (called randomized sample). The results show that the analysis performed by standard sample tend to overestimate the values of the fiber quality parameters, differing from the results obtained with the randomized sample that is representative of all plot. It was observed that the variability of cotton fiber quality affected by water stress treatments were best represented using bolls obtained by randomized method. Consequently, in the case of experiments with water stress, the most representative method to collect cotton fiber, is through a sampling of all the plant, and not only of the middle third.
