Crescimento do Algodoeiro sob Salinidade da Água de Irrigação e Adubação Nitrogenada

Performance of colored cotton under irrigation water salinity and organic matter dosages

“…The increase in salinity of irrigation water promoted a reduction in water availability due to the high concentration of salts in the root zone, which may have caused a reduction in the plant metabolism, evidenced by the reduction of height of plants, stem diameter, number of fruits and fresh mass of the aerial part. These results corroborate those observed by Oliveira et al (2008) and Santos et al (2014), who observed that, when evaluating saline water levels in cotton cultivars, the fresh phytomass presented linear declining behavior. The reduction in the expression of biometric characteristics with the increase of irrigation water salinity levels was also observed by Nascimento et al (2017b) in okra cultivation, Araújo et al (2016) in melon cultivation, Nobre et al (2014) in castor bean cultivation and Sá et al (2013) in papaya cultivation.…”

“…The height of plants, stem diameter, fruit number and number of leaves of the cotton was not influenced by the interaction between salinity and organic matter doses, corroborating the results observed by Santos et al (2014) and Nobre et al (2010) when evaluating irrigation water salinity levels and nitrogen fertilization on the growth of colored cotton and sunflower plants, respectively. By analyzing the isolated effects of the sources of variation, it is observed that, in general, the increase of the organic matter doses stimulated the cotton growth ( Figures 1A, B, C, D and E).…”

“…However, the authors point out that, despite this tolerance, the culture can suffer substantial reductions in its growth, production and quality of the product obtained when exposed to the saline stress condition (Oliveira et al, 2008). Thus, one aspect that has been studied is the use of fertilizers in the plants under salinity conditions, demonstrating that the use of biofertilizers in saline environments may reduce the effects of salinity on plant growth (Dias et al, 2016;Lima et al, 2014;Santos et al, 2014).…”

Uses of the reject brine from inland desalination for fish farming, Spirulina cultivation, and irrigation of forage shrub and crops

“…The three species experienced an inhibition of its growth measured in 10% of their mass for each additional mS·cm −1 [92]. The use of nitrogen fertilization did not achieve significant improves in the cotton growth within a similar range of saline water [93]. Finally, fruit trees as papaya (Carica papaya L.) were also tested under saline conditions [94], irrigated with brackish waters only or together with bovine liquid manure as in the case of guava (Psidium guajava L.).…”
