ABSTRACT Cowpea is broadly cultivated worldwide, especially in semi-arid or arid regions where soil or irrigation water salt contents can negatively influence the species’ productive capacity. The objective of this study was to evaluate the morphophysiological responses of cowpea genotypes to irrigation water salinity. The experiment was conducted in a greenhouse, under a completely randomized design with nine replications and in a 5x3 factorial scheme. Treatments consisted of five levels of irrigation water electrical conductivity - EC (EC0: 0.55; EC1: 1.60; EC2: 3.20; EC3: 4.80 and EC4: 6.40 dS m-1), applied from the 15th day after sowing (DAS), and three cowpea genotypes (G1: BRS Imponente; G2: MNC04-795F-168 and G3: MNC04-795F-159). EC increases at 35 DAS promoted stem diameter reductions of 8.0% (G1), 11.4% (G2), and 7.7% (G3), indicating different resistance to salinity by each genotype. Leaf area reductions at 25 and 38 DAS were 30.9% and 38.8% for EC0 and EC4, respectively. The BRS Imponente cultivar presented a performance superior to those of G2 and G3 in relation to stem diameter and stem dry matter at 25 DAS, and root-shoot and root-leaf ratios at 38 DAS.

ABSTRACT Indication of salt-tolerant cotton cultivars can make the agricultural exploitation with saline water irrigation feasible in the Brazilian semi-arid region. Thus, this study aimed to evaluate the gas exchanges and growth of cotton cultivars irrigated with saline water. The study was conducted in pots adapted as drainage lysimeters under greenhouse conditions, using a sandy loam Entisols as substrate. Treatments were distributed in completely randomized design, in 5 x 2 factorial arrangement, relative to five levels of irrigation water electrical conductivity - ECw (1.5, 3.0, 4.5, 6.0 and 7.5 dS m-1) and two cotton cultivars (BRS 368 RF and BRS Safira). Increase in irrigation water salinity inhibits the vegetative growth and gas exchanges of the cotton cultivars BRS Safira and BRS 368 RF. Leaf area and instantaneous carboxylation efficiency are the most affected variables. Physiological and growth performance of the cultivar BRS Safira in response to water salinity was higher than that of BRS 368 RF.

ABSTRACT: The use of plant species for the phytoremediation of soils contaminated with herbicides is an alternative that has been emphasized to minimize the effects of the persistence of agrochemicals in the environment. The objective of this study was to evaluate the tolerance potential of winter species in soils contaminated with sulfentrazone and fomesafen. The experiment was in a completely randomized design with four replications. Doses of fomesafen (0.0, 0.125, 0.250, and 0.5 kg ha-1) and sulfentrazone (0.0, 0.3, 0.6 and 1.2 kg ha-1) were applied during the pre-emergence of phytoremediate species (black oat, vetch, birdsfood trefoil, radish and lupin). Forty five days after the emergence of the species, the phytotoxicity (%), leaf area (cm2), stalk and/or stem diameter (mm), height (cm) and dry matter (g) variables of the plants were evaluated. Data were submitted to analysis of variance by F test; when significant, linear or non linear regressions were applied to evaluate the effect of herbicide doses on the studied species. Birdsfood trefoil was the less tolerant species to fomesafen and sulfentrazone. Black oat was less affected by the application of fomesafen doses, but it was highly susceptible to sulfentrazone. Radish presented tolerance only up to the fomesafen dose of 0.25 kg ha-1; as for sulfentrazone, the species showed tolerance. The most tolerant species to fomesafen and sulfentrazone, regardless of the dose, was the lupine, which is a possible alternative for the phytoremediation of soils contaminated with these herbicides.

The experiment was conducted in a greenhouse in the city of Pombal, Paraíba, PB, in the period April-May 2015. We adopted a completely randomized design in a factorial 4 x 3 x 2 design, consisting of four levels of irrigation water salinity (0.3, 1.5, 3.0 and 4.5 dS m-1) and three substrates [S1= ground; S2= soil + organic compound (2:1); and S3= soil + manure (2:1)] , and two varieties of melon (V1 = Gaúcho Casca de Carvalho; V2 = Hales Best Jumbo), with four replications and three plants per repetition. Plants were kept in containers with a capacity of 0.5 dm3 for 32 days after sowing, when they were evaluated for growth and accumulation of dry matter. Growth and dry matter accumulation of both varieties were reduced with increasing irrigation water salinity. The growth and accumulation of dry mass of the Hales Best Jumbo variety in the substrate composed of soil with organic compost was less affected by salt stress. The Gaúcho Casca de Carvalho variety is the most sensitive to salt stress regardless of the substrate used. Keywords: Cucumis melo L., salt stress, organic compound

Mulched Drip Irrigation

Freshwater shortage is becoming one of the major limiting factors for the sustainable development of agriculture in arid and semi-arid areas of north China. A two-year field experiment about mulched drip irrigation on maize was conducted in Hetao Irrigation District with five irrigation water salinity levels (total dissolved solids; 1, 2, 3, 4, and 5 g·L−1). The effects of irrigation water salinity on maize emergence, growth, yield, grain quality, and soil salt were determined. The results indicated that with the soil matric potential of -20 kPa and irrigation quota for each application of 22.5 mm, the irrigation water salinity showed negative influence on maize emergence and maize morphological characteristics (plant height, leaf area index, stem diameter, and dry matter), as irrigation water salt concentrations exceeded 3 g·L−1. The water use efficiency decreased linearly with the irrigation water salinity raised from 1 g·L−1 to 5 g·L−1, while maize grain protein increased and starch content decreased with the increase of irrigation water salt contents. Additionally, both the vertical radius and horizontal radius of salt isoline by mulched drip irrigation reduced with the irrigation water salt concentrations, when the irrigation water salinity was above 3 g·L−1. Summarily, irrigation water salinity of 3 g·L−1 was recommended for maize mulched drip irrigation in this study.

The incorporation of organic substrate into the soil can reduce aluminum toxicity in pigeon pea (Cajanus cajan (L.) Millsp.) plants, making it a viable alternative for use by small farmers in acidic soil regions such as the northeast semi-arid regions of Brazil that contain toxic aluminum in the soil. The aim of this study was to evaluate the effect of increasing aluminum doses and different commercial substrate concentrations on the initial growth of the pigeon pea. The experiment was undertaken in a greenhouse using a completely randomized design with a 5 × 3 factorial scheme. The first factor consisted of five doses of aluminum (0, 13.5, 27, 54, and 108 mg L-1) and the second factor consisted of three percentages of commercial substrate Vivato Slim Pro® (0%, 10%, and 20%), with five replicates per treatment, totaling 60 experimental units. The variables evaluated were plant height; total chlorophyll; shoot, root, and total dry matter; and root volume. The use of the commercial substrate attenuated the aluminum toxicity and favored the initial growth of pigeon pea plants, regardless of the concentration used. Thus, the aluminum was detrimental to the initial plant growth at all tested concentrations and showed more pronounced signs of toxicity on the root volume.

This work evaluated the development of colored cotton submitted to irrigation water of different salinity levels and organic matter doses from tanned manure. The experimental design was completely randomized in a 4 x 4 factorial scheme with 3 replications, totaling 48 experimental plots. The factors studied were 4 doses of organic matter (1, 4, 7 and 10%) and four levels of irrigation water salinity (0.26; 1, 2 and 4 dS m-1). The variables analyzed were plant height, stem diameter, number of leaves, number of fruits and fresh shoot mass. Significant effect of organic matter was observed on all studied variables, with a positive response on the increase of all variables as a function of increasing doses of organic matter. The isolated effect of salinity was significant for all parameters evaluated, except for the number of leaves, with significant reductions of 6.03; 3.27; 5.23; 6.94% in the parameters: plant height, stem diameter, number of fruits and shoot fresh weight respectively, for each unit increase of irrigation water salinity. The interaction between the variation sources studied had a significant effect only for fresh shoot mass, where the highest average for this parameter was observed at 10% organic matter dosage at irrigation water salinity level of 1.0 dS m-1.

ABSTRACT In Pernambuco, state in the northeastern region of Brazil, in the coastal areas, due to the intrusion of seawater, the waters used for sugarcane irrigation can have high salt contents and cause serious problems to soil and plant. The present study aimed to evaluate the effects of irrigation with saline water on the physiology of sugarcane, variety RB867515, irrigated under five salinity levels of 0.5; 2.0; 3.5; 5.0 and 6.5 dS m-1 in a completely randomized design, with four replicates in drainage lysimeters. The study was conducted in the period from December 2014 to June 2015, at the Federal Rural University of Pernambuco (UFRPE). Salinity levels were obtained by dissolving NaCl and CaCl2 in water from the local supply system (ECw = 0.5 dS m-1). Leaves were analyzed for stomatal conductance, transpiration and photosynthesis at 140, 229 and 320 days after planting (DAP) and for water potential at 137, 243 and 318 DAP. Increase in irrigation water salinity inhibited all variables at the respective plant ages and with greater intensity in the first evaluations (140 and 229 DAP) for stomatal conductance and transpiration. Photosynthesis and water potential showed the greatest linear reductions at the last data collection (320 and 318 DAP), respectively. Increase in salinity of irrigation water hampered water potential and gas exchange in the leaves of RB867515 sugarcane.

The objective was to evaluate growth and tolerance of bell pepper cultivars under salt stress in the seedling stage. The experiment was carried out in protected environment (greenhouse) at the Center of Sciences and Agrifood Technology (CCTA) of the Federal University of Campina Grande (UFCG), located in the municipality of Pombal, Paraíba, from August to September 2014. Five bell pepper cultivars (C1 - Dulce All Big; C2 - All Big; C3 - Italiano Amarelo Gigante; C4 - Rubi Gigante; C5 - Casca Dura Ikeda) were evaluated at five levels of irrigation water salinity (0.6 (control); 1.2; 1.8, 2.4 and 3.0 dS m-1), arranged in 5 × 5 factorial scheme, in a completely randomized design, with four replicates. Bell pepper cultivars were grown on trays for 20 days after sowing, period in which they were evaluated for emergence, growth, phytomass accumulation and tolerance index. The increase in irrigation water salinity reduced bell pepper emergence, growth and dry matter accumulation, and the cultivars C2 - All Big and C4 - Rubi Gigante were the most tolerant to salinity in the initial growth stage. Tolerance to salinity occurred in the following order: C2 - All Big > C4 - Rubi Gigante > C1 - Dulce All Big = C5 - Casca Dura Ikeda > C3 - Italiano Amarelo Gigante.
