Currently, the international scientif ic community is increasingly promoting the use of alternatives eco-friendly to the environment to solve agricultural problems, such as soil salinization. The use of agricultural homeopathy, as one of these alternatives, has increased because of its safety and proven effectiveness. This study assessed the effect of attenuating salinity stress (NaCl) of the homeopathic medicine Natrum muriaticum (NaM) on photosynthetic rate (TF) and morphometric variables of the common bean plant (Phaseolus vulgaris L.) variety white testa Quivican in initial plant growth stage. A completely randomized experimental design was applied with bifactorial arrangement (2A × 4B) where A = salinity levels (0 and 75 mM) and B = homeopathic dynamizations (NaM-7CH, NaM-13CH, NaM-7+13CH and distilled water [AD] as homeopathic control) with f ive replicates per treatment. The TF measurements were done twice a week, and the morphometric variables were measured at the end of the experimental evaluation period (35 days). In general, the assessed morphometric variables were favored with the application of the homeopathic treatments NaM 7CH and NaM 7+13CH; the increase in root length (LR) and fresh leaf biomass (BFH) were greater even when the plants were in salinity stress conditions (75mM NaCl). The TF reached the highest value when the plants in saline medium were treated with NaM-7CH, and an increase greater than 50% in PR was observed with respect to the (AD) control treatment. These results demonstrated a great potential of agricultural homeopathy as a bio-safe and low-cost alternative to increase P. vulgaris L.  tolerance to NaCl and achieve greater areas of this crop.

Secondary salinization of arable lands, and declining irrigation water resources are major challenges for crop production. We investigated synergistic effects of salinity and irrigation on Phaseolus vulgaris L. in a 4 × 3 factorial experiment with four salinity levels (0, 4, 8 and 12 ppt) coupled with 3 irrigation regimes that reflected a deficit, normal and excess irrigation for the region. Growth and ecophysiological variables were measured, and data submitted to Analyses of variance, Correlation and Factor analyses in the Minitab Version 17 software. Salinity stress decreased height (35.05 to 31.97 cm) as salinity increased from 0 to 8 ppt. Number of leaves, number of branches, number of flowers and fruits as well as fruit mass and harvest index all decreased as salinity stress increased. Plants in the deficit irrigation regime had higher water use efficiency (1.27g/l) and transpiration use efficiency (29.51 g/l) compared to those under higher irrigation regimes. Salinity and water stress effects on yield and plant water relations would significantly impede production of this crop, with significant yield losses of over 400% in higher salinities. Therefore measures to alleviate soil salinity are necessary for enhanced P. vulgaris production in such saline contaminated areas.

O experimento foi conduzido em casa de vegetação no Departamento de Engenharia da Universidade Federal de Lavras, em Lavras - MG, em delineamento inteiramente casualizado , com seis repetições e cinco níveis de salinidade da água: 0,10; 1,0; 2,5; 4,0 e 5,5 dS m-1. Os parâmetros vegetativos e produtivos foram negativamente influenciados pela salinidade da água de irrigação. Verificou-se também que a salinidade do solo aumentou com o aumento dos níveis em salinidade da água. As maiores salinidades da água de irrigação resultaram em menores consumos de água pelas plantas.  UNITERMOS: Feijão comum, salinidade da água, salinidade do solo.  SANTANA, M. J.; CARVALHO, J.

ESAL 686) and salt accumulation in the soil. The experiment was carried out in a greenhouse at the Engineering Department of Lavras Federal University, Lavras-MG, in a complete randomized design with six replications and five water salinity levels: 0.10; 1.0; 2.5; 4.0 and 5.5 dS m-1. The vegetative and productive parameters were negatively affected by the irrigation water salinity. It was also verified a soil salinity increase as salinity levels increase in the irrigation water. The highest water salinity level caused the lowest water consumption by plants.  KEYWORDS: French bean, irrigation water salinity, soil salinity

This study aims to determine grafting’s efficiency to improve tomato growth and production under salinity stress conditions. A commercial tomato hybrid (cv. Bark) and eight wild tomato accessions were evaluated at molecular, physiological and agronomic levels. At the molecular level, two robust gene-targeting marker systems (Conserved DNA-Derived Polymorphism; CDDP and Start Codon Targeted Polymorphism; SCoT) were employed. Bark cv. was grafted as a scion onto the four tomato genotypes’ roots as stocks. The rootstocks effect was evaluated by growing plants at 0, 100 and 200 mM NaCl. Our results showed that grafting enhanced plant shoots and roots growth (plant height, number of branches, plant fresh weight, root length, and root fresh and dry weight), fruit yield (total yield, number and weight of fruits) and fruit quality (Vitamin C, firmness and total soluble solids) in Bark on most tested rootstocks. A significant interaction between salinity levels and rootstocks for all measured hormones, antioxidants and proline was observed. In conclusion, our consistent results from the three approaches (molecular, physiological and agronomical) revealed that the four genotypes (LA1995, LA2711, LA2485 and LA3845) were found to be grouped and exhibit better performance under salinity stress conditions. Furthermore, grafting could be a low-cost alternative method to improve salt tolerance in sensitive tomato genotypes.

Application of antioxidant materials like absicisic acid to alleviate salinity stress and promote cotton growth is high effectiveness target, whereas cotton plant is an attractive industrial crop. Pot experiment was conducted to evaluate the effect of salinity stress and absicisic acid (antioxidant materials to alleviate salinity stress) on cotton growth and macro nutrients status in shoots of cotton plants. Plants subjected to two salinity levels (2500 and 5000 ppm as diluted sea water), and tap water (250ppm) as control, sprayed absicisic acid (ABA) with two concentrations (20 and 40 ppm of ABA) and distilled water as a control. Salinity decreased stem and leaves dry weight compare to the control treatment. The lower concentrations of ABA (20 and 40 ppm as a foliar spray) improve dry weight of stem and leaves. Reversely, leaves/stem ratio decreased with both concentrations of the absicisic acid. The increment in dry weight of leaves and stem or their sum showed its higher values by application 40 ppm from ABA under the 5000 ppm salinity level and also under fresh water treatment but under the 2500 ppm treatment the highest values were by 20 ppm of growth regulator. Nevertheless, L/S ratio decreased by ABA treatment, whereas, the high concentration of ABA (40ppm) was super than lower concentration (20ppm) under both salinity levels. Generally, it can be used diluted seawater in irrigation of cotton plant with spraying abscisic acid to alleviate the harmful effect of salinity.

The response of Phaseolus vulgaris L. variety Quivican to the application of homeopathic medicines as growth promoters was assessed during its initial plant development. A completely randomized experimental design was applied with three homeopathic treatments: TH1 [MgM-31CH (Magnesium metallicum 31 CH)], TH2 [MaMnP-3CH (Magnesium-Manganum phosphoricum)], TH3 [TH1 + TH2), and distilled water as Control group. The analyses showed the best results in the plants that received TH3 with a significant increase (P ≤ 0.05) with respect to the control group in the following response variables: length of stem (47.14%) and root  (30.27%); biomass of fresh root (13.57%), leaves (68.36%) and stem (11.88%); dry biomass of leaves (84.72%) and stem (36.11%); leaf area (21.74%), stem diameter (39.54%) and number of leaves (16.66%). These results confirm that agricultural homeopathy is an eco-friendly and technologically viable alternative for bean cultivation because it stimulates growth, which allows obtaining more vigorous plants with greater productive potential and less dependent on agrochemicals. Because homeopathic medicines are harmless, the balance of the agroecosystem is also improved, achieving a positive impact in the short, medium and long term besides their application in conventional and organic agricultural production.
