<p>Haricot bean (<em>Phaseolus vulgaris</em> L.) is one of the most important cash crops and export commodities besides its use in human food and soil fertility improvement. Phosphorus (P) is one of the major bio-elements that limits agricultural production. However, phosphate-solubilizing fungi play a noteworthy role in increasing the bioavailability of soil phosphates for plants. The purpose of this study was to evaluate the effects phosphate solubilizing fungi on the growth of haricot bean plants. Cultural and morphological features were used to tentatively identify the fungal isolates to genus level. Based <em>In vitro</em> phosphate solubilization efficieny conducted in both solid and liquid PVK medium following standard procedures, two best isolates were selected and evaluated under greenhouse for their performance on haricot bean. Under greenhouse experiment, shoot height (47.31 cm plant<sup>-1</sup>), root length (41.01 cm plant<sup>-1</sup>), nodule number (65.67 plant<sup>-1</sup>), nodule dry weight (0.59 g plant<sup>-1</sup>), shoot fresh weight (62.73 g plant<sup>-1</sup>), shoot dry weight (14.33 g plant<sup>-1</sup>), number of pod (12.89 plant<sup>-1</sup>), 50-seed weight (35.89 g plant<sup>-1</sup>), P content (0.59%) and N content (1.96%) were significantly increased by co-inoculation of two isolates (PSFAP) in the soil amended with rock phosphate (RP) compared to control. Moreover, the highest number of leaves (59.55 leaves plant<sup>-1</sup>) and root fresh weight (14.19 g plant<sup>-1</sup>) were recorded as a result of inoculation with isolate PSFP compared to control. The present study indicated the presence of potential plant associated fungi that possess phytobeneficial traits for extending their use as microbial biofertilizers after testing their suitability for the desired purpose.</p>

A field experiment was carried out during therabiseason of 2004-05 to find out the effect ofRhizobiumand phosphate solubilizing bacterial (PSB) inoculants on symbiotic traits, nodule leghemoglobin, and yield of five elite genotypes of chickpea. Among the chickpea genotypes, IG-593 performed better in respect of symbiotic parameters including nodule number, nodule fresh weight, nodule dry weight, shoot dry weight, yield attributes and yield. Leghemoglobin content (2.55 mg g−1of fresh nodule) was also higher under IG-593. Among microbial inoculants, theRhizobium+ PSB was found most effective in terms of nodule number (27.66 nodules plant−1), nodule fresh weight (144.90 mg plant−1), nodule dry weight (74.30 mg plant−1), shoot dry weight (11.76 g plant−1), and leghemoglobin content (2.29 mg g−1of fresh nodule) and also showed its positive effect in enhancing all the yield attributing parameters, grain and straw yields.

AbstractOnly few studies in the plant tissue culture literature have examined the impact of lanthanoids, or rare earth elements, on in vitro plant organogenesis. In this study, using a model plant, hybrid Cymbidium Twilight Moon ‘Day Light’, the impact of six lanthanoids (lanthanum (III) nitrate hexahydrate (La(NO3)3 · 6H2O), cerium (III) nitrate hexahydrate (Ce(NO3)3 · 6H2O), neodymium (III) nitrate hexahydrate (Nd(NO3)3 · 6H2O), praseodymium (III) nitrate hexahydrate (Pr(NO3)3 · 6H2O), samarium (III) nitrate hexahydrate (Sm(NO3)3 · 6H2O), gadolinium (III) nitrate hexahydrate (Gd(NO3)3 · 6H2O) on new protocorm-like body (neo-PLB) formation on Teixeira Cymbidium (TC) medium was examined. 0 (control), 1, 2, 4 and 8 mg·dm-3 of each lanthanoid was tested. All lanthanoids could produce more neo-PLBs and neo-PLB fresh weight than TC medium lacking plant growth regulators (PGRs), suggesting some PGR-like ability of lanthanoids, although PLB-related traits (percentage of half-PLBs forming neo-PLBs; number of neo-PLBs formed per half-PLB; fresh weight of half-PLB + neo-PLBs) was always significantly lower than TC medium containing PGRs. Except for Gd, all other lanthanoids had no negative impact on the number of new leaves from neo-PLB-derived shoots, but all lanthanoids showed a significantly lower plant height, shoot fresh weight and shoot dry weight and, in most cases, SPAD (chlorophyll content) value. In addition, using the same concentration of the six lanthanoids, the ability to fortify root formation of neo-PLB-derived plantlets was also assessed. Except for Sm, all other lanthanoids significantly increased the number of roots, root fresh and dry weight.

Strawberry is considered as a salinity sensitive species and is adversely affected in response to the salt stress in terms of growth and yield. Pot experiments were conducted to determine the effect of exogenous salicylic acid (SA) application on physiology, growth, chlorophyll and mineral content of strawberry grown under salt stress and greenhouse conditions. Strawberry plants were treated with SA at different concentrations (0.0, 0.25, 0.50 and 1.00 mM). Salinity treatments were established by adding 0 and 35 mM of NaCl to a base complete nutrient solution. Salt stress negatively affected the growth, chlorophyll content and mineral uptake of strawberry plants. However, plants treated with SA often had greater shoot fresh weight, shoot dry weight, root fresh weight and root dry weight as well as higher chlorophyll content under salt stress. The greatest values were obtained with 1.00 mM SA treatment in both saline and non-saline conditions. Leaf water relative content (LWRC) was reduced in response to salt stress while electrolyte leakage was raised. SA treatments induced increases in LWRC and decreases in electrolyte leakage compared to the control under salt stress. With respect to the nutrient content, SA treatments increased almost contents of all nutrients in leaves and roots of strawberry plants under salt stress. The greatest values were often obtained by the 1.00 mM SA treatment. These findings suggest that the SA treatments can ameliorate the negative effect of salinity on the growth of strawberries.

Abstract The present investigation was to determine the effect of nano-TiO2 (2 to 6 nm) and waste water on early seedling growth of maize. The suspensions of nano-TiO2 either in deionized water or autoclaved waste water were applied at 100 mg/L, 50 mg/L and 25 mg/L under in vitro conditions. Analyses of waste water showed that it was not suitable for irrigation purposes as it had a higher content of heavy metals (Fe, Mn, Zn, Cd, Cr and Cu) which were above permissible levels for irrigation. The higher concentration of nano-TiO2 (100 mg/L) and waste water significantly inhibited seed germination, seedling growth and caused accumulation of phenolics in maize plants (p &lt; 0.05). The application of nano-TiO2 at 25 mg/L significantly increased shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, root area, chlorophyll a, chlorophyll b and carotenoids content (p &lt; 0.05). The adverse effects of waste water on growth attributes of maize were significantly ameliorated by nano-TiO2 at 25 mg/L (p &lt; 0.05). The treatment of waste water with nano-TiO2 (25 mg/L) is recommended before its utilization for agriculture purposes.

Plant stress due to NaCl compound will have an impact on the reduction of plant growth and yield.  Tolerant varieties are required  to increase plant production in coastal areas since these areas are closely related to salinity.  This study aimed to (1) determine the appropriate NaCl concentration for saline tolerance in maize stress selection, (2) determine the response of maize plant to salinity stress in nutrient culture, and (3) determine the response of new hybrid maize having adaptibility in coastal area.  Two experiments were run from November 2017 until May 2018. The first experiment was conducted in a greenhouse at the Laboratory of Agronomy, Faculty of Agriculture University of Bengkulu  to determine the tolerance response of 25 new hybrid maize to salinity in nutrient culture.  The second experiment was conducted on the coastal areas in Beringin Raya Village, Muarabangkahulu District, Bengkulu City to determine the response of new hybrid maize having adaptibility in a coastal areas.  The concentration of  NaCl at which level the LC50 was determined was found to be in 150 mM. This concentration was then used to test the tolerance of 25 new hybrid maize to NaCl stress.  The hybrids of CT18, CT19, CT22, CT25, CT31, CT33, CT34, CT40, CT47, and  CT50 showed good responses to the concentration treatment  of 150 mM NaCl based on plant fresh weight and shoot dry weight. The hybrids of CT17,CT19, and CT20 showed good adaptibility on coastal area based on the length of cob, diameter of cob, seed weight per cob, and cob weight per plant.  Among those three hybrids, CT17 and CT20 resulted low fresh weight and low shoot dry weight.  The factors other than NaCl in coastal area maybe affect better response. However, CT19 proved as a hybrid which was consistently in a good response to salinity stress both in nutrient culture and in coastal growing area.

Soil fertility and plant nutrition require an adequate management of essential macronutrients such as potassium (K) and phosphorus (P), which are mandatory for plant development. Bioleaching of K and P bearing minerals improves their chemical weathering and increases the performance of the biofertilization strategies. In this study, in vitro and greenhouse experiments were carried out to investigate P and K solubilization traits of nine Actinobacteria (P13, P14, P15, P16, P17, P18, BC3, BC10, and BC11) under fertilization with rock phosphate (RP). K and P solubilization were evaluated on Alexandrov and NBRIP media containing mica and six RP samples, respectively. The actinobacterial strains were able to solubilize K in Alexandrov medium supplemented with RP. However, when soluble P was used instead of RP, only four strains of Actinobacteria (Streptomyces alboviridis P18–Streptomyces griseorubens BC3–Streptomyces griseorubens BC10 and Nocardiopsis alba BC11) solubilized K. The solubilization values of K ranged from 2.6 to 41.45 mg/L while those of P varied from 0.1 to 32 mg/L. Moreover, all strains were able to produce IAA, siderophore, HCN, and ammonia and significantly improved the germination rate and the vigor index of wheat. The pot experiments revealed that four strains (Streptomyces alboviridis P18, Streptomyces griseorubens BC3, Streptomyces griseorubens BC10, and Nocardiopsis alba BC11) significantly improved the growth parameters of wheat, namely root length (1.75–23.84%), root volume (41.57–71.46%), root dry weight (46.89–162.41%), shoot length (8.92–23.56%), and shoot dry weight (2.56–65.68%) compared to the uninoculated control. These findings showed that Streptomyces griseorubens BC10 and Nocardiopsis alba BC11 are promising candidates for the implementation of efficient biofertilization strategies to improve soil fertility and plant yield under rock P and rock K fertilization.

Research is needed to better understand the influence of cell volume and fertility on watermelon transplant size and field performance in order to determine the most economic production practices. `Jubilee' watermelon transplants were grown using a 4 x 4 factorial experimental design consisting of 4 cell volumes (30.7, 65.5, 147.5, and 349.6 cm3) and 4 fertility rates (0, 1/4, 1/2, and full-strength Hoagland's solution). Transplant shoot dry weight significantly increased as cell volume and fertility increased. Increasing cell volume linearly increased watermelon number/ha and tons/ha for early and total harvest in 1995. The average weight per watermelon significantly increased for early-harvested fruit but not for total harvest as cell volume increased in 1995. Soluble solids concentration linearly increased with increasing cell volume for early and total harvests in 1995. Cell volume had no significant influence on the harvest parameters measured in 1997. In 1995, increasing fertility linearly increased watermelon number/ha and tons/ha for early harvests. Increasing fertility increased the soluble solids concentration linearly for early-harvested watermelons in 1997 but not in 1995. Fertility rate had no significant influence on any of the other harvest parameters measured in 1995 and 1997. The growing conditions and disease pressure in 1997 reduced melons/ha, yield, and soluble solids content when compared to 1995 values. The half-strength Hoagland's solution produced the greatest number of watermelons/ha, tons/ha, and the highest soluble solids concentration in 1995 and 1997. Pretransplant nutritional conditioning had no significant effect on total `Jubilee' watermelon production in Louisiana for 1995 and 1997.

Abstract Background Orobanche crenata is an obligate root parasite belonging to Orbanchaceae. Broomrape causes great damage to the faba bean. Several attempts were applied for controlling parasitic weeds. So, the aim of this work is to study the application of Trichoderma spp. as well as three rhizobacteria species in comparison to herbicidal effect of Glyphosate (Glialka 48% WSC) for controlling broomrape infesting faba bean (Vicia faba). Materials and methods Three pot experiments were carried out in the greenhouse of the National Research Centre, Dokki, Giza, Egypt during two successive winter seasons. Trichoderma inocula were adjusted to 3.6 × 108 propagules/ml and the bacterium inocula were adjusted at 107–109 colony-forming unit (CFU)/ml. All treatments were applied, before 1 week of sowing, at rate of 50 ml per pot in experiments I and II, while 100 ml per pot in experiment III. Results Trichoderma spp. (T. harzianum, T. viride and T. vierns) as well as three rhizobacteria species (Pseudomonas fluorescens, Bacillus subtilis and Bacillus pumilus) enhanced the growth parameters in faba bean plants, i.e. shoot length, shoot fresh weight, shoot dry weight and leaf number in the first experiment when applied without O. crenata infection. In the second experiment, all bio-control could protect plants against O. crenata infection, where it had better juvenile number reduction, than glyphosate after 2 months of application. Both B. subtilis and B. pumilus had the highest reduction to juvenile fresh weight, while their effect was equal to herbicide for juvenile dry weight, respectively. The bio-control agents had high effects until the 4th month, but it was less than that of the herbicide. In experiment III, the bio-control agents could highly reduce the juvenile parameters after 2 months, as well as juvenile fresh weight and juvenile dry weight after 4 months, than the herbicide, respectively. The bio-control agents were effective until 6 months, but less than the herbicide effect. All bio-control treatments highly increased the plant growth parameters, than the herbicide. Conclusion The application of Trichoderma spp. as well as rhizobacteria species could play an important role in controlling broomrape in faba bean as a natural bioherbicide.
