Beet cultivation with saline effluent from fish farming

Abstract

This study aimed to evaluate the distribution of salts along the soil profile, the biometric parameters and the yield of beet cultivars under different leaching fractions using saline effluent from fish farming, under the conditions of the Sub-middle São Francisco Valley. An experiment was conducted at the Caatinga Experimental Field of the Embrapa Semi-Arid, in 2013. The treatments were arranged in split plots composed of four leaching fractions (0, 5, 10 and 15%) in the plots, with saline effluent from fish farming, and three table beet cultivars in the subplots: Scarlet Super, Early Wonder 200 and Fortuna. The analysed parameters were: salt distribution along the soil profile, number of leaves, length and width of leaves and petioles, total and commercial yields. The application of leaching fractions of 10 and 15% promoted better salt distribution along the soil profile. The beet cultivar Fortuna showed the highest commercial yield for a lower leaching fraction.

Leaching of cations in soil cultivated with sugarcane subjected to saline irrigation and leaching fractions

“…From 94 DAP, it was also observed that most treatments under 0.17 leaching fractions had lower values of ECdw ( Figure 2), proving the effect of leaching fraction on the reduction of soil salinity, corroborating the results obtained by Simões et al (2016).…”

Cultivation of forage sorghum varieties irrigated with saline effluent from fish-farming under semiarid conditions

“…The increase in yield due to the application of leaching fractions with saline water was also observed in cowpea (Assis Júnior et al, 2007), peanut and beet (Simões et al, 2016). On the other hand, it is important to note that high leaching fractions may cause reduction in crop yield, for reducing the concentration of both potentially toxic ions and ions indispensable for plant mineral nutrition, as observed in the weight of corn grains grown under irrigation with saline water (3.3 dS m -1 ) and leaching fraction of 20% (Carvalho et al, 2012).…”

“…Higher values of electrical conductivity in the upper soil layers were also observed in the cultivation of beet (Ferreira et al, 2006;Simões et al, 2016) and peanut subjected to leaching fractions with saline water.…”

“…Some studies conducted with forage and vegetable crops cultivated with water from fish-and shrimp-farming tanks, supplied with saline water, have shown promising results (Carvalho Júnior et al, 2010;Gurgel et al, 2012;Simões et al, 2016). Among these crops, sorghum shows great production potential for cultivation under saline water and is considered as moderately tolerant to salinity (Dias & Blanco, 2010).…”

Parâmetros bioquímicos, fisiológicos e produtividade de sorgo granífero irrigado com água salina

“…Fração Sabendo-se que a retenção máxima de água do solo é dada quando o mesmo atinge a umidade na capacidade de campo, todo o volume de água acima desse valor será drenado, provocando assim a lixiviação dos sais no perfil do solo. Confirmando, assim, os dados apresentados na Tabela 4 mostram uma redução da CEes do solo com o aumento da FL, o que foi observado por diversos autores em cultivos de sorgo (Guimarães et al, 2016;Guimarães et al, 2022), beterraba (Simões et al, 2016) e milho (Freitas, 2022).
