ABSTRACT Saline irrigation water at high levels causes disturbance in the growth of more sensitive plants. The objective of this research was to evaluate the initial growth of Pityrocarpa moniliformis seedlings under different electrical conductivity in irrigation water through physiological and biochemical analyses. The experiment was conducted in a greenhouse with five water electrical conductivities (0.5, 2.0, 4.0, 6.0 and 8.0 dS m-1) and four repetitions of 20 plants each, arranged in a randomized block design. Application of the treatments with irrigation water containing NaCl began at 30 days after sowing. To determine the behaviour of the species, the following variables were analysed: stem diameter, plant height, number of leaves, leaf area, Dickson quality index, shoot dry mass, root dry mass and total dry mass, as well as the biochemical variables, such as the concentrations of total soluble sugars, free proline and chlorophylls a and b. The increase in irrigation water salinity hampered the growth of P. moniliformis seedlings, with electrical conductivity of 0.5 dS m-1 being the limit for maximum production. The results also indicated that the deleterious effects of salt stress on P. moniliformis seedlings variables increase in concentrations of proline, total soluble sugars and betaine glycine.

The availability and quality of the irrigation water are among the limitations for the development of agriculture in the semiarid. Aiming at gathering information on these limitations, this work aimed to evaluate the association between a water-absorbing polymer and water salinity in irrigation frequencies, as well as container volumes on the allometric and morphophysiological indices of seedlings of the papaya (Carica papaya) cultivar ‘Sunrise Solo’. The treatments were obtained from the combination between the water-absorbing polymer (0.0; 0.2; 0.6; 1.0, and; 1.2 g dm-3), the electrical conductivity of the irrigation water (0.3; 1.1; 2.7; 4.3, and; 5.0 dS m-1), and irrigation frequencies (daily and alternate), plus two additional treatments (0.75 and 1.30 dm3) to study the effects of the container volume, distributed in a randomized block design. At 55 days after sowing, the following characteristics were evaluated: ratio between stem height and diameter; ratio between shoot and root dry matter; root density; leaf blade area; ratio between total leaf area and root dry mass; specific leaf area; leaf area ratio; leaf mass ratio; and Dickson quality index. The allometric and morphophysiological indices were damaged by the increase of water electrical conductivity and favored by the application of the polymer and a higher irrigation frequency. In the production of papaya seedlings, a daily irrigation frequency must be prioritized, using containers of 0.75 or 1.30 dm-3, water with electrical conductivity up to 2.6 and 1.9 dS m-1 when irrigated daily or in alternate days, respectively, and 0.6 g dm-3 of polymer.

Irrigation Water Salinity

The carnauba (Copernicia prunifera [Miller] H. E. Moore) is a palm tree that has multiple uses and is of great economic and social importance for extractive families in Northeast Brazil. The objective of this work is to analyze the effect of saline water on the production of different progenies of carnauba. The experiment is arranged in a 5 x 36 factorial scheme in a randomized complete block design, with five replications and five plants per replication. The treatments consist of five levels of irrigation water salinity (with commercial NaCl levels, free of iodine: 0, 25, 50, 75, and 100 mM) and 36 free-pollination progenies. The following characteristics are evaluated: foliar length (H), collecting diameter (DC), survival rate (TS), number of leaves (NF), dry shoot mass (MSPA), dry mass of the root system (MSSR), and dry mass ratio of the root system to the shoot. The results reveal similar behavior among the progenies for the evaluated characteristics. However, significance is observed for the parameters leaf length, collection diameter, and survival rate when the progenies are subjected to salinity above 9.6 dS m-1. Another significant factor is the accumulation of Na+ in the aerial and radicular parts in salinity levels of 7.1, 9.6, and 12.0 dS m-1, with the root system being the most affected site. Thus, the tested progenies exhibit similar behaviors in tolerance to irrigation water salinity. Since the carnauba can produce seedlings in water with electrical conductivity of up to 9.6 dS m-1, this species is characterized as a bioindicator of saline soils and is recommended for planting in degraded areas.

ABSTRACT Information on the production of seedlings and initial growth of pomegranate irrigated with saline water is scarce in the Brazilian semi-arid region. The objective of this study was to assess the effect of irrigation water salinity levels on the growth and tolerance of pomegranate seedlings. The experiment was conducted in a greenhouse, located at the Federal Rural University of the Semi-Arid Region, Mossoró, RN, Brazil. A randomized block design with five treatments [electrical conductivities of irrigation water (ECw) of 0.6, 3.0, 6.0, 9.0, 12.0 dS m-1] and five replicates, with three plants per plot, was used. At 120 days after sowing, the following characteristics were evaluated: shoot, root and total lengths (cm); stem diameter (mm), dry mass of stem, leaves, root system and total (g); ratio between root and shoot dry mass; Dickson quality index and salinity tolerance. Growth and dry biomass accumulation in pomegranate seedlings were compromised with increased salinity in irrigation water, but with a lower intensity when subjected up to EC of 6.0 dS m-1. Regarding the criterion of evaluation of tolerance to salinity, pomegranate seedlings were moderately tolerant to salinity.

Saline irrigation water is becoming an important water source as fresh water is fast becoming a scarce resource in many areas of the world, including Eswatini, especially in arid and semi-arid regions.  A study to test the response of two varieties of spinach (fordhook giant and mustard) to salinity was conducted in a field pot experiment at the Faculty of Agriculture at the Luyengo Campus of the University of Eswatini.  The treatments were laid in a randomized block design (RCBD).  The experiment consisted of four treatments, each replicated twelve times.  Treatments were salinity levels of 0.0 dS/m, 1.5 dS/m, 2.0 dS/m and 3.5 dS/m.  All the treatments were subjected to similar agronomic practices. Spinach was grown and observed for a period of five weeks.  Plant height was measured and the number of leaves counted weekly throughout the experiment. Significant differences (P < 0.05) between salinity treatments were obtained for plant height beginning in week 2 but were more pronounced in week 3, 4 and week 5.  No significant differences were obtained for the number of leaves.  There were however, clear significant differences between spinach irrigated with none saline irrigation water compared to saline irrigation water.   It was concluded that irrigating spinach with saline water of more than 2.0 dS/m drastically reduce plant growth but not the number of leaves under the conditions of the experiment.

Zucchini culture is slightly sensitive to salinity and is among the ten vegetables of highest economic value, with characteristics of precocity and easy cultivation. These characteristics are some of the reasons for the expansion of its cultivation among small producers. Thus, the objective was to evaluate the effect of different levels of salinity in the irrigation water and biofertilizer types on the initial growth of the zucchini (Cucurbita pepo L.) culture. The experiment was carried out in the full sunlight in a randomized block design, in a 5x2 factorial arrangement. The treatments consisted of a combination of five types of biofertilizers (quail, sheep, mixed, bovine, and crab) and two salinity levels of the irrigation water (0.8 and 2.5 dS m-1), with five replicates. At 30 days after transplanting, the following variables were evaluated: electrical conductivity of the substrate, plant height, number of leaves, roots length, stem diameter, leaf area, chlorophyll content, dry mass of the aerial part, root dry mass, and total dry mass. Salt stress negatively interferes with the accumulation of zucchini plant biomass. Quail, bovine, and sheep biofertilizers are more efficient about plant height, number of leaves, and stem diameter. The sheep biofertilizer attenuates the salt stress for the dry mass of the aerial part, the root, and the total dry mass.

Nesse sentido, o objetivo do trabalho foi avaliar o crescimento de mudas de tamarindo irrigadas com água salina em solo sem e com biofertilizantes. O experimento foi conduzido de outubro de 2012 a janeiro de 2013, em ambiente telado no Centro de Ciências Agrárias, Universidade Federal da Paraíba, Areia, PB, no delineamento em blocos casualizados, com esquema fatorial 5 × 3, referente a irrigação com água de condutividade elétrica 0,5; 1,5; 3,0; 4,5 e 6,0 dS m-1 no solo sem biofertilizante, com biofertilizante comum e com biofertilizante enriquecido quimicamente. Inicialmente foi avaliado o índice de velocidade de emergência e aos 100 dias após a semeadura, a condutividade elétrica do extrato de saturação do solo, altura e diâmetro caulinar, número de folhas, massa de matéria seca de folhas, caule e raízes das plantas. O aumento da concentração de saís na água de irrigação promoveu aumento da salinidade do solo e inibiu a germinação, o crescimento biométrico e a produção de biomassa seca das mudas de tamarindeiro. Ao final do experimento concluiu-se que a salinidade prejudica a germinação e o crescimento inicial das mudas de tamarindeiro, mas com menor severidade nos tratamentos com biofertilizante. Os biofertilizantes inibiram os efeitos negativos da salinidade da água às mudas, com superioridade do biofertilizante comum em relação ao biofertilizante enriquecido quimicamente. Palavras - chave: Tamarindus indica, insumos orgânicos líquidos, estresse salino em mudas  LIMA NETO, A.

The irrigation with saline water reduces crop growth and yield, resulting in the need of new techniques that enable the use of this natural resource in fruit growing. In this sense, the objective of this study was to evaluate the effect of saline irrigation water associated with different nitrogen doses on guava rootstock cv. Paluma morphophysiology. The experiment was carried out in a completely randomized blocks design, testing 5 electrical conductivity of irrigation water - ECw (0.3, 1.1, 1.9, 2.7 and 3.5 dS m-1) and four nitrogen doses for fertilization (541.1; 773.0; 1004.9 and 1236.8 mg dm-3), in a 5x4 factorial, with four repetitions. The increase in the ECw from 0.3 dS m-1 negatively affected the morphophysiology of guava rootstock cv. Paluma, especially during the younger phase of the crop. The N dose of 541 mg dm-3 stimulated the increase of most morphophysiological variables in guava rootstock during the period studied. The nitrogen fertilization did not reduced the salt stress effect on the evaluated variables.

ABSTRACT The semi-arid region of the Brazilian Northeast has adequate edaphoclimatic conditions for the passion fruit production, but the water used for irrigation commonly has high concentrations of salts that are harmful to the plant growth and development. A previous supply of hydrogen peroxide induces the acclimation of plants under saline stress conditions, reducing deleterious effects on their growth and physiology. This study aimed to evaluate the gas exchanges and growth of passion fruit as a function of irrigation with saline water and exogenous application of hydrogen peroxide. The experiment was carried out under greenhouse conditions, using a randomized block design, in a 4 x 4 factorial arrangement, being four levels of irrigation water electrical conductivity (0.7 dS m-1, 1.4 dS m-1, 2.1 dS m-1 and 2.8 dS m-1) and four hydrogen peroxide concentrations (0 µM, 25 µM, 50 µM and 75 µM), with four replicates and two plants per plot. The hydrogen peroxide application attenuated the deleterious effects of the irrigation water salinity on transpiration, CO2 assimilation rate, internal carbon concentration, plant height and leaf area of yellow passion fruit, at 60 days after sowing, with the concentration of 25 µM being the most efficient. Irrigation using water with electrical conductivity above 0.7 dS m-1 negatively affects the gas exchanges and growth of passion fruit, being the stomatal conductance and leaf area the most sensitive variables to the salt stress.

The salinity is one of the stresses that more limits the income of the agricultural cultures, mainly in areas semiarid as the Northeast, though, it is known that the biostimulants are substances capable to alter the metabolism of the plant and to favor development under adverse conditions of stresses. In this context, it was aimed at with this work to evaluate the initial growth of the passion fruit plant irrigated with saline water and the application of biostimulants. The experiment was conducted at the Federal University of Campina Grande, campus Pombal, in factorial outline 5 × 3, corresponding to five salinity levels (S1 = 0.3; S2 = 2.3; S3 = 3.3; S4 = 4.3 and S5 = 5.3 dS m-1) and two biostimulants (B1 = Acadian and B2 = Crop Set) and treatment testifies (without an application of biostimulant). The dose used for each product was 4 ml L-1 of Acadian and 3 ml L-1 of Crop Set. It was used seeds of the passion fruit of the variety BRS-giant, sowed in containers of black polypropylene of 400 ml, containing sand and substrate Carolina Soil, in the proportion 1:1. For the 32 days after the sowing was determined the height, the root length, the fresh and dry mass (aerial, root and total) of plants, the biomass production and the index of tolerance the salinity. The data were submitted to the variance analysis of the test F at the level of 5% of probability, and when significant, the averages were submitted to the test Tukey for both factors, saline levels and biostimulants. The use of vegetable biostimulants increases the initial growth of the yellow passion fruit plant. The salinity in the irrigation water attacks the growth, however, I use of the biostimulant Crop Set lessens the harmful effect in passion fruit seedlings.
