“…Yet, according Rodrigues et al (2017) these organic inputs, while providing an increase in the electrical conductivity of the substrate, stimulate the growth and production of vegetal biomass. The results are in agreement with Lima Neto et al (2016), Carneiro et al (2017) and Oliveira et al (2017) when they noticed an increase in the concentration of salts of the soil with irrigation of waters with increasing salinity.…”

The salinity is considered one of the main obstacles to agriculture worldwide, constituting one of the limiting factors to the growth and development of the plants. The objective of this study was to evaluate the effects of salinity of irrigation water in the formation of seedlings two varieties of jackfruits, and with the application of common bovine biofertilizer and chemically enriched bovine biofertilizers. In this sense, an experimente was carried in greenhouse conditions, in the period from October 2015 to February 2016, in Areia County, Paraiba State, Brazil. The substrate used was a material collected of the first 10 cm of depth of a Dystrophic Regolitic Entisol. The experimental design was completely randomized in a factorial scheme 5 × 3 × 2, corresponding to levels of irrigation water saline of 0.5; 1.0; 2.0; 3.0 and 4.0 dS m-1, in soil without and with common bovine biofertilizer and enriched biofertilizer, tested with two varieties of jackfruit (jack-soft and jack-hard), and with six replicates. The biofertilizer after dilution in non-saline water (0.5 dS m-1), in proportion of 1:3, where was applied once to 10% of the substrate volume, two days before sowing. The increment of irrigation water salinity inhibited alls variables studied in the jackfruits plants, but with less intensity in the treatments with bovine common biofertilizer.

The yellow passion fruit is a plant climbing botanically that has a good geographical distribution in Brazil, with more than 150 species in the country. The presence of salts in soil and irrigation water is one of the main obstacles in agriculture in the world, caused by low rainfall and high evapotranspirative rates causing the salts to accumulate in the soil. However, alternatives have been sought to try to mitigate such limitations of seedling production, such as the use of biofertilizers in the soil. In this way, the objective was to evaluate the growth and development of yellow passion fruit seedlings under the effects of irrigation water salinity and the use of bovine biofertilizer on the substrate. An experiment was carried out in a greenhouse in the Center for Agrarian Sciences and Biodiversity, from october/2017 tomarch/2018, in county of Crato-Ceara, Brazil. The substrate used was the first 20 cm material of a yellow Red Argisol. The experimental design was completely randomized design (C.R.D) in a factorial scheme 5x2, referring to the electrical conductivity values of the irrigation water: 0.5; 1.0; 2.0; 3.0 and 4.0 dS m-1, in the soil without and with common biofertilizer, with three replicates. The biofertilizer, after being diluted in non-saline water (0.5 dS m-1) in the ratio of 1:3, was applied only once to 10% of the substrate volume two days before sowing. The increase in the salinity of irrigation water negatively affected the initial behavior of the passion fruit seedlings in terms of growth and development, especially in the treatments that did not receive the organic feed.

“…Potassium (K) is a nutrient demanded in great quantity by the culture of the sweet pepper, being the main source used by the producers is potassium chloride that has high saline index, being one of the main sources of salinization of the soil in cultivation. Potassium sulfate has a salt content equivalent to half of the salt content of potassium chloride, which makes it more suitable for soils with tendency to salinization [5].…”

Aims:The objective of this research was to investigate the effect of calcium silicate on gaseous exchanges and production factors in the sweet pepper, cultivated under conditions of soil salinity induced by potassium fertilization, in protected cultivation. Study Design: The experiment was arranged in a randomized complete block design in a 2 × 5 factorial scheme with five replications. Place and Duration of Study: The experiment was conducted in the sector of Olericultura and Experimentation of the course of Agronomy from October 12, 2018 to February 2019. Methodology: The experiment was arranged in a randomized complete block design in a 2 × 5 factorial scheme (two sources of correction: calcareous and silicon and five increasing rates of KCl equivalent to 150, 300, 450, 600 and 700 kg ha -1 of K 2 O). Ten treatments with five replicates where each experimental unit consisted of a polyethylene pot, with a volume of 19 dm 3 . The electrical conductivity, the determination and quantification of silicon in soil and plant, liquid photosynthesis, stomatal conductance, intercellular CO 2 concentration, transpiration, water use efficiency and instantaneous carboxylation efficiency were analyzed. Dias et al.; JEAI, 40(2): 1-12, 2019; Article no.JEAI.50539 2 Results: With the increase of K 2 O in the soil there was a tendency of reduction in liquid photosynthesis, transpiration, stomatal conductance, intercellular CO 2 concentration, water use efficiency and instantaneous carboxylation efficiency in the presence and absence of calcium silicate. Higher rates of K 2 O (300, 450 and 600 kg ha -1 ) reduced the length and yield of sweet pepper fruits in the presence and absence of calcium silicate. The rate of 150 Kg K 2 O favored the growth of sweet pepper plants in the presence of calcium silicate. Conclusion: It is concluded from the research that the dose of 300 kg ha -1 of K 2 O, in the presence of calcium silicate, provided the best results for the electrical conductivity of 2.76 dS m -1 , silicon content in the soil of 5.70 mg kg -1 , 14% silicon leaf content, improving photosynthetic rates, transpiration, water use efficiency and fruit production. The increase in salinity reduced fruit yield, in the presence and absence of Si. Original Research Article
