“…Pace et al (1999) measured the root and shoot parameters of cotton grown under drought and observed reduction in growth, development, and distribution of stressed cotton plants roots as compared to control treatments. Similarly, reduction in root dry matter due to water deficit in cotton plant has been observed by Ferreira et al (2013). Pace et al (1999).…”

Water scarcity is the most serious abiotic stress restricting plant productivity throughout the world. Losses in crop yield due to drought exceed from losses caused by other environmental factors. In this review article different morphological, physiological and yield attributes of cotton under drought stress, mechanism of drought induced losses and various management strategies to mitigate drought stress have been discussed. Drought stress reduces growth of leaf, stem and root, interferes with leaf water relations, photosynthesis, respiration, reduces water-use efficiency and ultimately yield of cotton. Under water deficit conditions cotton shows various responses to cope with drought stress. The major mechanisms include accumulation of osmoregulators, plant growth regulators and production of heat shock proteins. Different management strategies to alleviate water deficit stress like foliar application of osmolytes, potassium and growth regulators (hormones), various drought responsive genes, proteins at molecular level, screening and breeding programs against drought tolerance and mulching are also discussed in this paper.

“…On average, the reductions were 20.2%, 32.5%, 36.9% and 33.6%, in water regimes of 80%, 60%, 40% e 20% of evapotranspiration replacement, respectively. Other reports also observed that water stress reduced the overall plant stature of cotton (Baldo et al, 2009;Ferreira et al, 2013). According to the first authors, this occurred concomitantly with a 35% reduction in leaf-area index, prompting an 8% reduction in solar radiation interception.…”

The Water Safety Plan (WSP) approach is an iterative method focused on analyzing the risks of water contamination in a drinking water supply system, from catchment to consumer, in order to protect human health. This approach is aimed at identifying and drastically reducing water contamination in the entire drinking water system, through the identification and mitigation or, if possible, elimination of all factors that may cause a chemical, physical, microbiological and radiological risk for water. This study developed a proposal of WSP for the drinking water supply system (DWSS) of Mortara, Italy, in order to understand which are the preliminary evaluation aspects to be considered in the elaboration of a WSP. The DWSS of Mortara (a town of 15,500 inhabitants, located in northern Italy) consists of three drinking water treatment plants (DWTPs), considering the following main contaminants: arsenic, iron, manganese and ammonia. Potential hazardous events and associated hazards were identified in each part of the water supply system. The risk assessment was carried out following the semi-quantitative approach. The WSP proposal for Mortara was very useful not only as a risk mitigation approach, but also as a cost-effective tool for water suppliers. Furthermore, this approach will reduce public health risk, ensure a better compliance of water quality parameters with regulatory requirements, increase confidence of consumers and municipal authorities, and improve resource management due to intervention planning. Further, some new control measures are proposed by the WSP team within this work.Keywords: arsenic, drinking water, risk assessment, risk management, water safety plan. desde a captação ao consumidor, visando à proteçãoda saúde humana. Objetiva-se identificar e reduzir drasticamente a contaminação da água em todo o sistema de água potável pela identificação e mitigação ou, se possível, a eliminação de todos os fatores que podem causar um risco químico, físico, microbiológico e radiológico para a água. Este estudo desenvolveu uma proposta de PSA para o sistema de abastecimento de água potável de Mortara (Itália), a fim de compreender quais são os aspectos de avaliação preliminar a serem considerados na elaboração de um PSA. O sistema de abastecimento de água potável de Mortara (uma cidade de 15.500 habitantes, localizada no norte da Itália) consiste em três estações de tratamento de água, considerando os seguintes contaminantes principais: arsênio, ferro, manganês e amônia. Eventos perigosos potenciais e riscos relacionados foram identificados em cada parte do sistema de abastecimento de água. A avaliação do risco foi realizada seguindo a abordagem semi-quantitativa. A proposta do PSA para o sistema de abastecimento de água potável de Mortara contribuirá para reduzir os riscos à saúde pública, assegurar um melhor cumprimento dos parâmetros de qualidade da água, dos requisitos regulamentares, do aumento da confiança dos consumidores e autoridades municipais, assim como melhorar a gestão de recursos devido ...

“…Plant height decreased under skip irrigation, which might be due to varietal characteristics and less water availability. Ferreira et al (2013) found reduction in root and shoot length of matured cotton crops under water deficit conditions. Shoot length and dry matter contents of stressed cotton plants decreased which might be due to less growth in water scarcity conditions.…”

Drought is one of the most emerging threat that causes a severe reduction in cotton plant growth and development. Being cotton is a major cash crop has great threat to prevailing drought events in Pakistan. A field experiment was conducted in Kharif season 2018 at Research Area of MNS-University of Agriculture, Multan, Pakistan to assess the role of foliar applied kaolin and jasmonic acid on vegetative growth, gas exchange and reproductive traits of cotton under normal irrigated and artificial water deficit conditions. The experiment was laid -out in a factorial randomized complete block design with split – split plot arrangement. Main plots were allocated for irrigation levels, sub-plots for two -cotton genotypes viz. NIAB − 878 and SLH − 19 while sub – sub plots for treatments of kaolin and Jasmonic acid. Water deficit stress was created by skipping irrigation at flowering for 21 days. Foliar sprays of Kaolin (5%, w/v) and Jasmonic acid (100 μM) were applied alone or in combination at 60 days after planntinon both to normal irrigated and water-stresse skip irrigation while irrigation water alone was sprayed in control plots. Both cotton genotypes responded variably to normal irrigated and skip conditions. Skipping irrigation for up to 21 days at flowering caused a significant decrease in leaf relative water content, SPAD values, net photosynthetic rate and seed cotton yield in both the genotypes. Seed cotton yield showed an overall decline of 24.7% in skip over Normal irrigated crop. The genotype NIAB − 878 produced maximum seed cotton yield of 3.304 Mg ha −1 in normal that dropped to 2.579 Mg ha −1 in skip, thus showing an average decline of 21.9 %. Similarly, SLH − 19 produced 2.537 Mg ha −1 seed cotton under normal that dropped to 1.822 Mg ha −1 in skip, showing an average decline of 28.2%. The Application of Kaolin and JA Jasmonic acid, either applied individually or in combination, improved vegetative and reproductive development of both cotton varieties in normal and skip regimes. However, combined kaolin and Jasmonic Acid application proved to be more beneficial in terms of seed cotton production and other parameters studied.
