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

Abstract: A B S T R A C TThis study aimed to evaluate the cultivation of forage sorghum subjected to different leaching fractions with saline effluent from fish-farming under semiarid conditions. The experiment was set in a randomized block design, with four blocks, in split plots, composed of four leaching fractions (0; 5; 10 and 15%) and three forage sorghum varieties ('Volumax' , 'F305' and 'Sudão'). Irrigation was performed using saline effluent from fish farming with electrical conductivity of 2.5 dS m -1 . The ana… Show more

“…However, in the present study, the increment of the water depths increased the FM and individual DM of sorghum and the intercropped forage cactussorghum system (Figures 2 and 3). Similar trend was reported by Guimarães et al (2016) and Silva et al (2014) for sorghum in single crop system; and by Oseni & Aliyu (2010) and Wang et al (2015) for sorghum Table 2. Individual productivity on fresh basis (FM) and on dry basis (DM), and dry matter content (DMC) of 'Orelha de Elefante Mexicana' forage cactus (Opuntia stricta) and 'SF-15' sorghum (Sorghum bicolor), in single crop system and intercropping system (forage cactus-sorghum), under different irrigation water depths (saline water irrigation at 355, 563, 725, 867, and 1,012 mm per year, plus rainfall), in the Brazilian Semiarid Region (1) .…”

“…Freire (2012) reported the tolerance of 'Orelha de Elefante Mexicana', in comparison to other cultivars, when irrigated with saline water at 3.6 dS m -1 every 14 days. Guimarães et al (2016) also verified the tolerance of irrigated sorghum with saline effluent from fish farming.…”

“…Poucas variáveis de crescimento e de acúmulo de matéria seca do sorgo foram afetadas pelos distintos regimes hídricos (Tabelas I e II). Este resultado pode estar associado à alta tolerância do sorgo à seca e ao excesso de água combinados ao estresse salino (Guimarães et al, 2016;Guimarães et al, 2019). Nestas condições, o sorgo limita as suas atividades metabólicas (Bell et al, 2015).…”

“…Por outro lado, as plantas sujeitas ao excesso hídrico possuem sua condutância estomática afetada e diminui as taxas de fotossíntese e de crescimento, ocasionando em queda da produção da parte aérea e de raízes. Todavia a resposta ao déficit e ao excesso varia conforme o nível de estresse (Guimarães et al, 2016).…”

“…It presents high biomass yields per unit area and has been adapted to the silage process (Neumann et al, 2002), thus, it is an alternative for fodder in these environments. including the cultivation site (Albuquerque et al, 2013) fertilization (Santos et al, 2014b), and water availability (Tardin et al, 2013) and salinity (Guimarães et al, 2016).…”
