“…Nobre et al (2013) also observed that ECw negatively influenced plant height of castor bean BRS Energy to 67 DAS, which found that there were decreases in the order of 6.22% (16.72 cm) in AP per unit increased in ECw. Sá et al (2016) found a decrease of 3.73 cm in plant height per unit increased in ECw.…”

Plants grown under salt stress are adversely affected, however, it has been suggested the use of organic inputs in order to mitigate the deleterious effects of salinity. As a result, it aimed to evaluate the effect of different electrical conductivities of irrigation water due to the application of organic fertilizers in the cultivation of castor bean. The experiment was conducted in greenhouse located at State University of Paraiba, municipality of Catolé do Rocha-PB, Brazil. It adopted a completely randomized design (CRD), in a factorial scheme 5 x 3, with 8 repetitions. The first factor was the electrical conductivity of irrigation water (ECw) 0.5; 1.5; 2.5; 3.5 and 4.5 dS m -1 and the second factor refers to organic fertilizers: control treatment, biofertilizers beef and cow urine. There was interaction between the electrical conductivity x organic fertilizer factors. The unit increased from 0.5 dS m -1 of electrical conductivity of irrigation water reduced the growth, development and dry matter production of castor bean. The application of bovine growth provides greater biofertilizer castor. Furthermore, the organic raw material attenuates the effects of salt stress.

“…Sá et al (2016) found that increase in salinity levels caused linear reductions in salt tolerance index of all the varieties of castor bean, with 63.82% reductions to cultivate LA Guarani, 79.80, 75.51 and 77.91% for BRS Energy cultivars BRS Gabriela and IAC 028, respectively. Graciano et al (2011) observed that peanut cv.…”

“…Several studies have shown the harmful effects of saline irrigation water on the peanut crop (Correia et al, 2009;Graciano et al;2011;Santos et al, 2012;Sousa et al, 2012) and other oilseeds like castor bean (Nobre et al, 2013Santos et al, 2013;Lima et al, 2014;Sá et al, 2016;), jatropha , sunflower (Morais et al, 2011;Maciel et al, 2012), and legumes like beans (Neves et al, 2008;Garcia et al, 2010;Bezerra et al, 2010;Aydin et al, 2012). However, most studies have not shown the effect of biofertilizers as a way to mitigate the effects of salt stress on peanuts, mainly in the reproductive phase.…”

Peanut (Arachis hypogaea) is one of the most cultivated oil plant worldwide since it is widely consumed as food. In this sense, this work aims to evaluate the growth, production and tolerance of peanuts under the effect of different levels of electrical conductivities in irrigation water and bovine biofertilizer. The experiment was conducted in a greenhouse located at the State University of Paraíba -Campus IV, municipality of Catolé do Rocha, Paraíba, Brazil. The experimental design was completely randomized with a factorial arrangement of 4 x 2, with six repetitions. There are two treatments: the first consisted of the combination of the electrical conductivity (ECw) of 0.5; 1.5; 3.0 and 4.5 dS m -1 in irrigation water and the second is the application of bovine biofertilizer (with and without). Absolute growth rates and relative plant height, stem diameter and leaf area, number of pods per plant, 100 seed weight, number of seeds per plant, seed weight, seed mass + grains, root dry mass, shoot and total and tolerance index were assessed. From the results obtained, it can be concluded that the electrical conductivity of the irrigation water from 0.5 dS m -1 significantly reduced the growth and production of A. hypogaea, however the application of bovine biofertilizer increased the results obtained.

“…BRS-Energia) seeds used in this research were provided by EMBRAPA, Campina Grande, Paraíba, Brazil. According to Sá et al (2016), this cultivar is more salt tolerant than other commercial cultivars. The research was divided into three stages: (i) characterization of the effects of salt stress on seed germination and seedling establishment, (ii) selection of beneficial priming techniques for castor bean seeds, and (iii) evaluation of the action of the best castor bean priming techniques against salt stress.…”

Castor bean (Ricinus communis L.) cultivation requires production techniques appropriate for its growth conditions. Thus, the characterization of the deleterious effects of salinity on seed germination and on seedling establishment and the evaluation of the use of priming techniques on seeds could reduce replanting costs and improve emergence uniformity, preparing plant responses to salt stress. The goals of this current research were to characterize the deleterious effects of salinity on seed germination and on seedling establishment and to evaluate the use of the seed priming techniques as a tool to minimize these deleterious effect. In this research, castor bean seeds, cv. BRS-Energia was used to characterize effects of salt stress on germination and seedling establishment. Then, some chemicals such as PEG-6000 and H 2 O 2 were evaluated to find the beneficial priming techniques for castor bean seeds against salt stress. Our results indicate that water imbibition by the seed under salinity conditions decelerated the time of exposure to salinity. Salinity also affected the germination of castor bean seeds under an Ψs of -0.4 MPa and seedling growth was already affected under an Ψs of -0.16 MPa. Priming with CaCl 2 , NaNO 2 , NaNO 3 and PEG-6000 showed promising results under an Ψs of 0.0 MPa, but priming with NaNO 3 and PEG-6000 were ones that contributed most to better germination and establishment of seedlings under saline conditions. However, NaNO 3 is the most recommended priming agent for castor bean because accelerated seed germination, reducing the time to emergence and planting risks.
