Tests were done on the effects of titanium dioxide spray on Pinto bean (Phaseolus vulgaris L. c.v ‘c.o.s.16’). The study was conducted as a factorial experiment in a randomized complete block design with four replications for two years (2014 - 2015). Treatments consisted of two factors; the first factor was stage of plant growth that spraying was applied (rapid vegetative growth, flowering and pod filling); and the second factor was that of different concentrations of titanium dioxide nanoparticles (TiO<sub>2</sub>) that consisted of spray with water (control), nano titanium dioxide at concentrations of 0.01%, 0.02%, 0.03% and 0.05%. Activity of guaiacol peroxidase (GPX), activity of superoxide dismutase (SOD), activity of catalase (CAT), activity of peroxidase (POD), malonyldialdehyde (MDA) Content and 8-deoxy-2-hydroxyguanosine (8-OHDG) content were assayed. Results showed that effect of nano TiO<sub>2</sub> was significant on activity of superoxide dismutase (SOD), activity of catalase (CAT), activity of peroxidase (POD), malonyldialdehyde (MDA) Content and 8-deoxy-2-hydroxyguanosine (8-OHDG) content. Results of combined analysis of variance showed that the effect year significantly affected on SOD and 8-OH-2-DG (P ≤ 0.05). The effect of different amounts of titanium dioxide nanoparticles (TiO<sub>2</sub>) significantly affected (P ≤ 0.05) on MDA and 8-OH-2-DG. The effects of different amounts of titanium dioxide nanoparticles and year were significant on SOD, POD, MDA and the amount of 8-deoxy-2-hydroxyguanosine in P ≤ 0.05. None of the physiological traits were affected by spraying of nano titanium dioxide. The effects of TiO<sub>2</sub> nanoparticles times of spraying and year were significant on SOD, CAT and 8-deoxy-2-hydroxyguanosine (P ≤ 0.05). Interaction effects of nano TiO<sub>2</sub> concentrations × nano TiO<sub>2</sub> spraying times did not have a significant impact on SOD, CAT, POD, GPX, MDA and 8-OH-2-DG. Although, all trait were affected by interaction effects of year × nano TiO<sub>2</sub> concentrations × nano TiO<sub>2</sub> spraying times with the exception of GPX (P ≤ 0.05).

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.

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.
