“…The effect of PGPR applications on chlorophyll readings in the study is in good agreement with the results of Yildirim et al (2008aYildirim et al ( , 2008b in radish grown in saline conditions. PGPR treatments gave elevated reading values when compared with the non-inoculated controls in these studies.…”

This study was conducted to investigate the effects of root inoculations with Bacillus cereus (N2-fixing), Brevibacillus reuszeri (P-solubilizing), and Rhizobium rubi (both N2-fixing and P-solubilizing) on plant growth, nutrient uptake, and yield of broccoli in comparison with manure (control) and mineral fertilizer application under field conditions in 2009 and 2010. Bacterial inoculations with manure compared with control significantly increased yield, plant weight, head diameter, chlorophyll content, nitrogen (N), potassium (K), calcium (Ca), sulfur (S), phosphorus (P), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu) content of broccoli. The lowest yield per plant, plant weight, steam diameter, and chlorophyll content were recorded in the control, but the manure with Bacillus cereus (BC), Rhizobium rubi (RR), and Brevibacillus reuszeri (BR) inoculations increased yield 17.0%, 20.2%, and 24.3% and chlorophyll content by 14.7%, 14.0%, and 13.7% over control, respectively. Bacterial inoculations with manure significantly increased uptake of macronutrients and micronutrients by broccoli. In conclusion, seedling inoculation with BR and especially RR may partially substitute costly synthetic fertilizers in broccoli.

“…Interação entre salinidade e fósforo na cultura do rabanete Yildrim et al (2008), avaliando o desenvolvimento do rabanete em duas condições de salinidade (1,86 e 12,14 dS m -1 ), observaram cerca de 6,5 folhas por planta no meio menos salino, e que no meio mais salino houve redução no NF em cerca de 38%. Redução no número de folhas, em resposta à salinidade, também foram encontrados para outras culturas, como rúcula (SILVA et al, 2008), milho pipoca (OLIVEIRA et al, 2009), entre outras culturas de valor agronômico.…”

“…Para as plantas cultivadas sem adubação fosfatada (P 1 ), foi observada a maior redução da MSR (81,6%) na salinidade S 4 em relação a S 1 , enquanto que, nos demais níveis de P, foram observados reduções de 72,0%; 55,4% e 41,7%, para P 2 , P 3 e P 4 , respectivamente. Resultados semelhantes foram obtidos por Yildrim et al (2008), que avaliaram o desenvolvimento do rabanete em solo salino e verificaram significativa redução na massa seca das raízes.…”

“…Outra causa possível para redução dos parâmetros de desenvolvimento vegetal observado neste trabalho, pode estar relacionado a um possível desbalanço nutricional das plantas provocado pelas maiores salinidades (TAIZ; ZEIGER, 2004), conforme observado por Abdelrahman (1987) e Yildrim et al (2008) para cultura do rabanete. Alguns autores também constataram desbalanço nutricional em virtude da salinidade para outras culturas, como berinjela (BOSCO et al, 2009) e meloeiro (MEDEIROS et al, 2008), entre outras culturas de interesse agronômico.…”

Resumo -O uso de água salina, na irrigação, tem sido um desafio para os pesquisadores e produtores rurais, sendo constantemente desenvolvidos estudos que possibilitem o uso de água, de qualidade inferior, sem afetar o rendimento e qualidade dos produtos agrícolas. Este trabalho foi realizado com o objetivo de avaliar o efeito de diferentes níveis de salinidade da água de irrigação e doses de fósforo na cultura do rabanete. O delineamento experimental adotado foi inteiramente ao acaso, arranjados em esquema fatorial 4 x 4 com três repetições. Os tratamentos resultaram da combinação de quatro níveis de salinidade da água de irrigação (S 1 -0,5; S 2 -2,0; S 3 -3,5 e S 4 -5,0 dS m -1 ) com quatro doses de fósforo (0; 100; 200 e 300 mg dm -3 ). As variáveis avaliadas foram: número de folhas, área foliar, massa fresca e seca das raízes. A cultura do rabanete respondeu significativamente a interação entre salinidade e fósforo para área foliar, massa fresca e seca das raízes; e de forma isolada para número de folhas. Doses crescentes de fósforo reduziram à sensibilidade da cultura do rabanete à salinidade de até 3,5 dS m -1 . O manejo da adubação fosfatada é uma alternativa para amenizar o efeito da salinidade no desenvolvimento da cultura do rabanete. Palavras-chave -Raphanus sativus L.. Salinização. Plantas-efeito do fósforo.Abstract -The use of saline water for irrigation has been a challenge for the researchers and farmers, studies continually being developed to enable the use of lower quality water without interfering with the yield and quality of products. This work was conducted to evaluate the effect of different salinity levels water irrigation and phosphorus doses in radish. It was used an entirely statistical randomized design, in factorial scheme 4 x 4, with three replications. The treatments resulted from the combination of four salinity levels of irrigation water (S 1 -0.5; S 2 -2.0; S 3 -3.5 and S 4 -5.0 dS m -1 ) with four phosphorus levels (0; 100; 200 and 300 mg dm -3 ). The variables evaluated were: number of leaves, leaf area, root fresh and dry weight of roots. The radish responded significantly the interaction between salinity and phosphorus for leaf area, fresh and dry weight of roots, and isolated the factors for number of leaves. Increasing doses of phosphorus reduced the sensitivity of radish culture to salinity up to 3,5 dS m -1 . The management of phosphorus is an alternative to alleviate the effect of salinity in the development of radish.

“…PGPR colonize the rhizosphere of plants and promote growth through various direct and indirect mechanisms (Glick, 1995). They have been suggested to ameliorate the growth of plants grown under environmental stress conditions, protecting plants from the deleterious effects of environmental stresses (Karlidag et al, 2011;Sandhya et al, 2010;Yildirim et al, 2006Yildirim et al, , 2008Yildirim et al, , 2011. The growthpromoting effect of PGPR may be mediated by reduction of stress ethylene production via the action of 1-aminocyclopropane-1-carboxylate (ACC) deaminase (Mayak et al, 2004); the synthesis of phytohormones such as indole-3-acetic acid (IAA), salicylic acid (SA), and gibberellin (GA) (Arkhipova et al, 2007;Forchetti et al, 2010;Turan et al, 2014); alleviation of the oxidative damage (Kohler et al, 2008); inducing changes in the expression of reactive oxygen species (ROS)-scavenging enzymes; and improved photosynthetic performance (Gururani et al, 2013).…”

The aim of this study was to determine the effects of selected plant growth-promoting rhizobacteria (PGPR) on some physiological characteristics, plant growth, yield, and plant nutrient content of lettuce grown under different irrigation levels. Field experiments were carried out as split plot based on randomized complete block design with three replications. Three irrigation levels, I1 = 100% (control), I2 = 75%, and I3 = 50% of the field capacity (FC), were determined at the 0–15 cm soil depth by time-domain reflectometry (TDR), as main plots and three levels of bacterial species consisting of no bacterial inoculation (control), Bacillus megaterium TV 6D (B1), Bacillus subtilis TV 12H (B2) as sub plots in 2012 and 2013. Physiological characteristics, plant growth, yield, and plant nutrient content of lettuce was significantly affected by PGPR and irrigation quantities. Results showed that decreasing irrigation quantities significantly decreased the growth, dry and fresh head weight, and yield of lettuce in both years. Moreover, lower irrigation levels caused a decrease in leaf relative water content (LRWC), stomatal conductance (SC), and plant nutrient element content, but an increase electrolyte leakage (EL) and lipid peroxidation [malondialdehyde (MDA)]. However, PGPR inoculations significantly increased the growth, nutrient element content, LRWC, SC, and yield but decreased EL and MDA of lettuce plants grown under lower irrigation levels. The results of the study suggested that PGPR inoculations could alleviate the deleterious effects of lower irrigation conditions on the growth and yield of lettuce plants.
