Abstract:

Isolation of phosphate solubilising bacterial strains was carried out from rhizosphere, roots and nodules of chickpea, to study the viability for solubilisation of tri-calcium phosphate and the effect on growth of chickpea plants. The potential of isolated bacterial strains to solubilise phosphate was qualitatively evaluated by the measurement of a clear zone around the colonies. The diameter of this zone ranged from 21 to 83 mm. Phosphate solubilisation, by phosphate solubilising bacterial isolates, was quantified by spectrophotometry and was found to range from 65 to 130.5 μg/mL. The drop in pH ranged from 5.6 to 3.6. The plant growth, shoot phosphorus and nitrogen concentrations, nodulation efficiency and nitrogenase activity were significantly enhanced, showing the positive effect of phosphate solubilising bacteria inoculation. Phosphate solubilising bacterial strains CPS-2, CPS-3 and Ca-18 had the maximum positive effect on shoot length, shoot dry weight and nodulation of chickpea plants. Treatments inoculated with non-phosphate solubilising bacterial strains IFA1 and IFA2 showed the minimum values in all the parameters.

Abstract:

The main focus of the present study is to evaluate the effect of priming of green gram (Vigna radiata) with phosphate solubilising bacteria (PSB) during drought stress. Drought is the major abiotic stress factor which diminishing the growth and development of agricultural in Kerala. So immediate steps need to be taken to overcome the adverse effect of drought stress for the development of agriculture. Phosphate Solubilizing Bacteria are one of the best microorganisms found to be simultaneously increasing the insoluble soil Phosphorus uptake by the plant and crop yield. In the study, the seeds of Vigna radiata were subjected to priming treatment with 0.5 % and 1% phosphate solubilising bacteria. Physiological and biochemical parameters like germination percentage, root and shoot length, relative water content (RWC), amount of chlorophyll, protein, proline and yield were studied. Inoculation with phosphate solubilising bacteria showed remarkable variation in both physiological and biochemical parameters of green gram plants. Among the two concentrations tested, 1% phosphate solubilising bacteria was found to be effective in mitigating the effect of water stress, stimulating early flowering and also in increasing yield.

Abstract:

Biocompost has been identified as an alternative to chemical fertilizers that increased soil microbial population and soil enzyme activities in sustainable farming. The objective of this field study was to evaluate the effect of three halophytic composts in combination with farmyard manure and phosphate solubilising bacteria (<i>Bacillus megaterium</i>) on soil microflora and enzyme activities. The results show that among nine treatments given, the application of <i>Suaeda</i> compost in combination with farmyard manure and phosphate solubilising bacteria (T<sub>9</sub>) significantly increased the soil microflora such as bacteria, fungi and actinomycetes and soil enzyme activities such as dehydrogenases, alkaline phosphatase, cellulase and urease in soil cultivated with <i>Arachis hypogaea</i>.

Abstract:

Chickpea is one of the important pulse crops among legumes due to its high protein content. During the last few decades chickpea production has declined because of various biotic and abiotic factors. To increase its production farmers are relying on the traditional methods (using chemical fertilizers) that pollute the environment. An alternative to chemical fertilizers is the eco-friendly process of endophytic inoculation. Compatible endophytic coinoculations improve plant growth as compared to single inoculation due to the synergistic performance of the constituent bacteria. In the current study, the compatibility of six bacterial inoculants (BM5 (rhizobial), BP2 and P36 (phosphate solubiliser), RE2, HE8, and ME9 (other endophytes) was tested. Among these bacterial inoculants, endophyte ME9 was found to be compatible with phosphate solubilising bacteria (P36) and rhizobial culture BM5. However, the endophytic bacteria RE2 and HE8 were found to be incompatible with phosphate solubilising bacteria and rhizobial bacteria. Further, individual inoculation, combined compatible and combined incompatible inoculants were applied to chickpea seeds in the pot house experiment. The results revealed that among all the inoculations, compatible bacterial consortia (ME9, P36 and BM5) produced highest increase in shoot (225%) and root dry weight (600 %) and grain weight (250 % ) compared to the control group. The incompatible inoculations were ineffective in improving the root dry weight, shoot dry weight, and grain weight in comparison to the respective individual inoculations.

Abstract:

Deficiency of phosphorus can reduce the yield up to 15-20% and its availability to crop plants is the main issue, particularly in calcareous soils of Pakistan. Micro-organisms, phosphorus solubilizing bacteria (PSB) and sulphur oxidizing bacteria (SOB) have the ability to make P accessible for optimum plant growth, under conditions of nutrients disparity. Therefore, six treatments i.e. control, Yz dose of NPK, full recommended dose of NPK, Yz NPK+ SOB, Yz NPK + PSB and Yz NPK + SOB+ PSB were applied in a field experiment to investigate the integrated role of SOB and PSB with NPK fertilizers for enhancing the maize production. The treatment was concluded to have major impact on agro-morphological traits, seed quality and growth parameters of maize. Results depicted that the use of Yz NPK + SOB + PSB gave maximum germination count/plot (151.33), plant height (189.03 cm), number of ears/plant (1.60), grains/ear (472.33), 1000-grain weight (305.67 g), grain yield (5350.50 Kg/ha), harvest index (31.23%), leaf area (379.77 cm2), total dry matter accumulated (181.43 g/plant), crop growth rate (30.60 g/day), net assimilation rate (9.31 g/day) and protein contents (8.49%).

Abstract:

Phosphorous is considered as a major parameter for crop yield. Its availability to plant is independent of its abundance. For the plants to utilize phosphorous, it is to be converted to absorbable form. Here, the part rendered by phosphate solubilizing bacteria is significant for it plays a crucial role in the formation of plant usable phosphate from organic forms. In the present work, an effort had been made to isolate and identify phosphate solubilising bacterial isolate from the rhizhospheric soils of various plants in Ponthenpuzha forest. One of the isolate from Cymbopogon citrates responded positively to Pikovskaya’s medium by producing a halo zone during in vitro culture. Colony features and 16S rRNA sequence analysis identified the isolate as Burkholderia sps. We have reported the presence of genus Burkholderia in the rhizospheric zone of Cymbopogon citratus. Further studies are warranted for species level identification of the isolate.

Nugraha et al, 2019. Solubilization of Inorganic Phospate by Burkholderia spp. Associated with Oil Palm Rhizosphere in Mineral Acid Soil. JSLO 8(1):86-93.Phosphate Solubilizing Bacteria (PSB) play important role by enhancing phosphate availability bounded with Al3+ or Fe3+ in acidic soils to oil palm plants through release the inorganic phosphate by enzyme or organic acids solubilization. The aims of this study were to isolate of PSB from oil palm rhizosphere and to conduct a comparative analysis of the solubility inorganic phosphates source by selected PSB. The ability of 15 selected PSB to grow and solubilize aluminum phosphate (AlPO4) and iron phosphate (FePO4) was examined and identified. The highest phospate solubilising efficiency showed K3.1 isolate with phosphate solubilization index 3.2 on NBRIP media. Quantitative analysis revealed that isolate K3.1 solubilized 53.52 mg/mL phosphate in 5 days after being inoculated in AlPO4 containing liquid medium, isolate A4 solubilized 63.45 mg/mL phosphate in 5 days after being inoculated in FePO4 containing liquid medium accompanied by a decrease in pH of the growth medium. Based on the 16s rRNA gene sequence analysis, isolate K3.1 and A.4 were closely related to Burkholderia arboris and Burkholderia gladioli. This potential isolates can be used in order to make oil palm crops more sustainable especially on marginal soil with low pH and less dependent on inorganic P fertilizers.

Abstract:

A study was carried out at the experimental farm of School of Agricultural Sciences and Rural Development, Nagaland University, Medziphema campus, dist. Nagaland, India during the Kharif season (June to October) of 2017 and 2018 to assess the influence of integrated nutrient and weed management on soybean growth, yield and quality. The split-plot design was used with three replications: three nutrient management treatments and five weed management treatments in the main-plot and sub-plot, respectively. The pooled results revealed that the application of 50% RDF+50% organic through Rhizobium+Phosphate Solubilising Bacteria recorded significantly lower weed density and weed dry weight. Plant height (46.12 cm), plant dry matter (10.00 g plant-1), number of pods plant-1 (53.97), seed yield (16.28 q ha-1), straw yield (22.69 q ha-1), oil content (18.70%) and protein content (38.10%) were recorded highest under 75% RDF+25% organic through FYM+Phosphate Solubilising Bacteria. All of the weed treatments recorded lower weed density and dry weight over the weedy check significantly. Weed free treatment (hand weeding at 15, 30 and 45 DAS) gave highest seed yield (20.67 q ha-1) and straw yield (26.28 q ha-1). It was followed by propaquizafop @ 0.075 kg a.i. ha-1+hand weeding at 45 DAS and pendimethalin @ 1 kg a.i. ha-1+hand weeding at 30 DAS. Weed free registered highest oil content (19.38%) and protein content (38.97%) which was statistically at par with propaquizafop @ 0.075 kg a.i. ha-1+hand weeding at 45 DAS and pendimethalin @ 1 kg a.i. ha-1+hand weeding at 30 DAS.

Abstract:

Phosphorus (P) is an essential nutrient in sustainable production of sugarcane. Due to low labile P in soil under sugarcane cultivation, evaluation of the efficiency of P uptake and the application of phosphate solubilising bacteria (PSB) play important roles in management of P fertiliser. To investigate the effect of using PSB on P uptake in sugarcane (variety CP57–614), a pot experiment was conducted with three replications in greenhouse conditions. The treatments were a combination of three P rates (0 (P0), 50 and 100% (~40 mg kg−1) as triple superphosphate, and two PSB strains (Enterobacter cloacae R13 (R13) and R33 (R33)) which were applied independently and simultaneously. Morphological characteristics of sugarcane and some biochemical parameters were evaluated in the rhizosphere at three harvesting times: 60, 95 and 140 days after planting (DAP). Whereas in low available P (P0), bacterial strain R33 improved P uptake along with sugarcane ageing, P uptake was diminished in non-inoculated treatment over time. Activity of PSBs in the rhizosphere (especially strain R33) prevented the sharp fall of P influx after 95 DAP in low available P condition. Indeed, activity of R33 in the rhizosphere decreased the dependence of P uptake on root development via improving P uptake. Therefore, influx was the main mechanism of P uptake in sugarcane. Sugarcane inoculated by PSBs acquired 76 and 81% of total P uptake from non-Olsen-P fraction in P0R13 and P0R33 respectively at 95 DAP. However, this amount was lower (70.4%) in P0R0. Furthermore, strain R33 improved P uptake efficiency in sugarcane by changing root morphology (e.g. specific root length and root length) and reducing soil limitations (e.g. enhancement of P compound solubility and P influx).

Abstract:

A two year field investigation was conducted to study the effect of integrated nutrient management in cabbage (Brassica oleracea var. capitata L.) under subtropical plains of Jammu during rabi 2014â€“2015 and 2015â€“16 at Vegetable Experimental Farm of SKUAST, Jammu, Jammu and Kashmir. The experiment was laid in RBD and comprised 14 treatments with three levels of nitrogen (50, 75 and 100 %) in combination with two levels of organic manures (FYM @20t/ha and Vermicompost@2t/ha) and seedling dip with two biofertilizers [Azotobacter and Phosphate Solubilising Bacteria (PSB)]. The results revealed that for all the morphological (50% head initiation and maturation) and yield parameters (head size, net and gross head weight and marketable yield), the treatment combination comprising 75% inorganic nitrogen + Vermicompost + Azotobacter + Phosphate Solubilizing Bacteria recorded significantly high values as compared to other treatment combinations and control. Quality parameters like TSS recorded non significant influence by the application of different organic manures (FYM and Vermicompost) in combination with biofertilizers and reduced quantities of N (50 and 75%),however ascorbic acid content in cabbage recorded statistically higher values (51.16 mg/100g) in the treatment having 50% of inorganic nitrogen + Vermicompost + Azotobacter + Phosphate Solubilizing Bacteria (PSB). Economically, the study pointed out that application of vermicompost in the treatment combinations resulted in higher values in cost of cultivation, thereby, lowering down B:C ratios as compared to FYM treatments. Maximum B:C ratio (1:2.55) was recorded in treatment having 75% inorganic nitrogen + Vermicompost + Azotobacter + Phosphate Solubilizing Bacteria as compared to 1.96 in control (100% NPK + FYM).

Abstract:

Phosphate-Solubilizing Bacteria (PSB) contribute to healthy plant growth, improved yield, and phosphorus utilization in several crops and are potentially useful as a bioinoculant for enhancing sustainable production. The objective of this study is to examine the response of Lady rosetta potatoes to Acinetobacter rudis inoculation as PSB under controlled and field conditions in Kotda chakar village, Ta. Bhuj, Dist. Kutchh, State- Gujarat, India. Plant growth and the productivity of Lady Rosetta potatoes, laboratory isolations, and culture experiments were conducted. The potato tubers were harvested 90 days post-inoculation. The results indicated that there is a significant (p < 0.05) increase in germination plant species compared to the control plots. Acinetobacter rudis has an equal impact on the weight and size of potato tubers, as well as the height and growth of Lady Rosetta potatoes. The control plots showed poor germination and stunted growth of the potato tubers and plants. An increase in P contents was observed following Acinetobacter rudis inoculation, which resulted in an overall increase in plant height, size, and weight of potato tubers. The study concluded that Acinetobacter rudis has enormous potential to be applied as an alternative to PSB for environmental reasons.

Though the plant growth promoting bacteria have several beneficial applications, due to some of the disadvantages in the field conditions, they lagged behind. In the current research work, native PGPR were isolated from the rhizosphere soil samples of maize with an aim to isolate the nitrogen fixing, phosphate solubilising and potash solubilising bacteria. Out of the several isolates, potent PGPR isolates viz., Paenibacillus durus PCPB067, Bacillus megaterium PCBMG041 and Paenibacillus glucanolyticus PCPG051 were isolated and identified by using the 16 S rRNA gene sequencing studies. Genomic DNA sequences obtained were deposited in the NCBI Genbank and accession numbers were assigned as MW793452, MW793456 and MW843633. In order to check the efficacy of the PGPR isolates, pot trials were conducted by taking maize as the host plant. Several parameters viz. shoot length, shoot weight, root length, root weight and weight of the seeds were tested in which PGP treatment showed good results (shoot length - 187±3.5 cm, shoot weight - 31±4 g, root length - 32±3.6 cm, root weight - 17±2 g, yield- 103.3±6.1 g) when compared to the chemical fertilizer treatment (shoot length - 177±3.5 cm, shoot weight - 25±3.6 g, root length - 24±3.5 cm, root weight - 14.6±1.52 g, yield- 85.6±7.6 g). Based on the results, it can be stated that these native PGPR isolates can be effectively used in the plant growth promotion of maize.

Abstract:

Oil palm and banana are the biggest commodity crop and the second largest fruit crop planted in Malaysia. Both oil palm and banana are highly nutrient-demanding crops that requires a large amount of fertilizer input. This presents an opportunity to find alternative source of nutrient that is much cheaper than the imported inorganic fertilizer. Currently, the most feasible alternative to the inorganic fertilizer is the recycling of the organic-rich oil palm empty fruit bunch (EFB) to produce EFB compost as well as the incorporation of nitrogen-fixing bacteria (NFB) and phosphate-solubilising bacteria (PSB) to the EFB compost to increase the supply of nitrogen and phosphorous to the plant at different stages of growth. Hence, the objective of this study was to isolate, screen and identify indigenous bacterium, from the root surroundings of oil palm and banana plant, with highest nitrogen-fixing and phosphate-solubilizing properties. Three NFB and PSB strains (Enterobacter cloaceae KU886016, Burkholderia cepacia KU925862, Serratia marcescens KU925861), were successfully isolated and formulated as biofertilizer for evaluation on oil palm and banana seedlings. Enterobacter cloaceae KU886016 showed higher root colonization ability compared to Burkholderia cepacia KU925862 and Serratia marcescens KU925861, as shown from the FESEM analysis. This finding is important as a direct indication on the suitability of using these bacteria in field application as biofertilizer. Long-term expectation is for this finding to be able to assist in reducing the dependency on imported inorganic fertilizers, reducing operational cost as well as promoting sustainable soil health.

Abstract:

In the present study, field experiments were performed over 10 consecutive years (2006–15) to assess the effects of biofertiliser and enriched biocompost on soil quality, total organic carbon (TOC) and rice yields in an Inceptisol. Experiments were conducted in a randomised block design with four replicates and five treatments: unfertilised control (T1); recommended doses of inorganic fertiliser (T2); biofertiliser with reduced (50%) inorganic N and P fertilisers (T3); reduced (50%) inorganic N and P fertilisers with 1 t ha–1 enriched biocompost (T4); and reduced (75%) inorganic N and P fertilisers with 2 t ha–1 enriched biocompost (T5). T3 improved soil chemical and biological properties with enhanced soil quality index (40%), total P (23%), total K (42%) and fungal (38%) and bacterial (44%) colony counts. T5 significantly improved the carbon pool index (29%) and available nutrients (N, P and K at rates of 37%, 22% and 10% respectively) and increased soil pH (11%), resulting in a higher sustainable yield index (39%) of rice. Fraction 2 (labile carbon) of TOC, total P, available K, microbial biomass carbon and phosphate-solubilising bacteria were key indicators to assess the suitability of these fertilisers in rice cultivation in north-east India.

Abstract:

Rhizobium microbial bacteria functioning that living a symbiosis relationship soil and leguminous plant root fixation of nitrogen to be utilized by plant superior performance during grain development stage. They can enter into symbiosis with leguminous plant, by infecting their root nodules. The legume crops are the bigger partner, often referred to as macro-symbiotic. Usually certain strains form nodule on the limited legume plants. Such a collection of strain is called cross inoculation group. Legume crops show a decrease in the nitrogenase activities observed in soil, the higher doses of nitrogen reduce nitrogen fixation on one hand and increase cost of production on the other. Rhizobium inoculation encourage both nutrient such as Mo and Fe nutrient increasing N-fixation capacity in soil with the effective agronomic practice directly plant root nodulation, nitrogen fixation, vegetative germination, maturity and yield of black gram. It is use of Rhizobium and phosphate solubilising bacteria (PSB) increases nitrogen and phosphorus uptake use efficiency from soil. Lesser efficiency of PSB has been showing through Co-inoculation with another profitable bacteria mycorrhiza. The main used of rhizobia, PSB and improvement of soil fertility and increased of yield of black gram and decrease the use of balance fertilizer.

Abstract:

The effect of inoculating single cultures of plant growth-promoting rhizobacteria (PGPR) on development of white beans seedling (Phaseolus vulgaris) was analyzed. Five PGPR were isolated from the rhizosphere of Okra plants and were assessed for abilities to solubilise phosphate and produce indole acetic acid (IAA). The phosphate solubilising index ranged from 6-10 while the concentration of IAA ranged from 17.48mg/l to 27.43mg/l. Serratia sp. produced the highest concentration of IAA (27.43mg/l) and had the highest solubilisation index (10mm). Bacillus sp. produced the least amount of IAA (17.48mg/l) while Staphylococcus sp. had the least solubilisation index (6mm). The highest percentage germination of 83.3% was observed in the seedling inoculated with Bacillus sp. The influence of microbial inoculation on root and shoot elongation was studied hydroponically for 7 days. Significant increases (P< 0.05) in root elongation were observed. The highest seedling root length (18.47cm) and shoot length (19.17cm) were observed with inoculation of Staphylococcus sp. and Bacillus sp. respectively. The use of these bacteria as bio-inoculants could be a sustainable practice to facilitate nutrient supply to white beans seedlings.

Abstract:

Mono-cropping in the farming system decline in farm profit, climate change, and food insecurity are some of the major concerns that lead to unsustainability in the agricultural production system in the Eastern Gangetic Plains. A study was conducted for three years from June 2019 to June 2022 at Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar, India, to assess the profitable and best rice-based cropping system through crop diversification for sustainable agriculture. Ten different cropping sequences were exploited using randomised block design and replicated thrice, with the system productivity ranging from 8.70 to 24.95 t ha−1 under the different cropping sequences. The system productivity was increased by 187% and profitability by 299.52% in the maize − Cole crops − sesame cropping system over the rice − wheat cropping system. A diversified cropping system with black gram − maize + vegetable pea − sesbania possessed significantly more soil organic carbon (0.49%), bacterial population (47.85 × 106 cfu/g soil), azotobacter population (42.96 × 104 cfu/g soil), phosphate solubilising bacteria (20.72 × 106 cfu/g soil), dehydrogenase activity (4.39 µg TPF/g/h), fluorescein diacetate hydrolytic activity (17.28 µg fluorescein/g/h) and acid phosphatase activity (451.46 µg pNP/g/h), as well as urease activity (47.21 µg NH4+/g/h), relative to the rice–wheat cropping system. Therefore, the adoption of vegetables and legumes as diversified crops are viable options for enhancing productivity, profitability and soil health in the EGPs.

Abstract:

The influence of biofertilizer inoculation viz. Azotobacter and Phosphate Solubilising Bacteria (PSB) alone and in different combinations with the recommended dose of chemical fertilizer (NPK: Nitrogen-Phosphorous- Potassium) on Jowar (Sorghum bicolor (L.) Moench) crop was tested during the Kharif season at the agricultural field (21040’76.97N; 78096’22.70 E Maharashtra State of India) to explore the possibility of reducing doses of chemical fertilizers and for better soil health. The results revealed significant improvement in growth characters such as the height of the plant (4.89% to 15.10%), number of internodes (1.69 to 6.39%), stem diameter (5.08% to 26.27%), the weight of the root system (7.32% to 29.27%), number of functional leaves (6.70% to 19.56%), the weight of fresh plant (8.45% to 17.17%) and weight of dry plant (9.15% to 24.29%) over the control treatment. Similarly, the weight of sorghum cob (11.33% to 47.67%), the yield of fodder (4.59% to 19.76%), grain yield quintal/hector (0.97% to 37.83%) was more in inoculated crop as compared to the controlled condition.

Abstract:

Aim of present research was to isolate and characterize the Pseudomonas strains phenotypically and genotypically from the rhizospheric soil of apple orchard at Maggota (Shimla district) Himachal Pradesh. Phenotypic identification of the test isolates was based on morphological, physiological and biochemical characterization of the bacteria followed by genotypic analysis using rRNA gene sequencing and RAPD-PCR analysis. The fourteen Pseudomonas sp. isolates were screened out for various plant growth promoting activities such as siderophore production, antifungal activity, phosphate solubilisation, HCN and ammonia production, production of plant growth regulators and lytic enzymes. Isolates showed production of plant growth regulators (auxins, gibberellins and cytokinins) in the range of 19.67-83.33μg/ml, 21.00-58.67 μg/ml and 12.33-43.33 μg/ml respectively. Pseudomonas strains showed phosphate solubilising activity in the range of 12.33-63.33 Pi μg/ml, 53.66-93.44 % SU siderophore production and 11.33-96.33mm (diameter) protease activity in plate assay. Five Pseudomonas isolates i.e. An-16-kul, An-1-mag, An-2-mag, An-3-mag and An-6-mag showed maximum antifungal activity against plant pathogenic fungi. Therefore, the aim of present investigation was to study multifarious plant growth promoting qualities of Pseudomonas sp. and to select more efficient PGPR strain of fluorescent Pseudomonas sp. which can be further used as biofertilizer.

Abstract:

The present study consists of the experiments on application of mineral solubilizing and plant growth hormone producing microbial strains in individual and /or combination under glass house conditions and their impact on enhancement in plant productivity of Adnenthera pavonina. Among microbial strains taken for the study, 6 phosphate solubilizing fungi, 4 iron ore leaching fungi, 5 phsophate solubilising bacteria and 11 isolates of Rhizobia had been used. Screening of ten fungal species and 5 bacterial isolates for their effects on growth of Adnenthera pavonine, done under pot culture in green house conditions, elucidated the best performance of Penicillum crysogenum Thom. 1 and Cunninghmella elegans Lendn. Combination of selected microbial inoculants for the individual test tree species were evaluated for their individual performance and /or in combination with the other selected inoculants in specific ratio of their inoculums. Under the dual inoculation experiment, selected mineral solubilisers (fungi/bacteria) were evaluated along with the combination of different isolates of Rhizobium and resulted selection of Penicillium chrysogenum and Cunnighmella elegans in 1:1 combination for better growth and development of seedlings under nursery conditions. The impact of Rhizobium inoculation alone or in combination with these fungal strains could not be observed and interpreted. However, the outcome the present study done under controlled experimental conditions may provide the plausible approach towards the development of nursery package and practice for development of quality planting material of this tree speices may be useful for the transplantation programe of revegetation of degraded land and environment.

Abstract:

The strains Priestia megaterium Ср-1 and Rhodococcus jostii CA-6 were shown to preserve phosphate-solubilising ability, nitrogen-fixing activity and synthesis of indole-3-acetic acid under osmotic stress conditions caused by sodium chloride in concentration range of 1197–2052 mmol/L, as well as to promote seed germination rate and development of small radish seedlings. Proline, betaine and sucrose were found to exert a beneficial effect on growth and ability of strains P. megaterium Ср-1 and Rh. jostii CA-6 to adapt to osmotic stress. Mass spectrometric analysis has revealed that intracellular synthesis of proline and betaine in both bacteria was directly proportional to sodium chloride concentration: rising NaCl level in the medium to 1197 mmol/L was accompanied by increase in proline level from 0.062 to 1.502 µg /mL (Rh. jostii CA-6) and from 0.089 to 2.105 µg /mL (P. megaterium Ср-1), in a similar manner betaine production grew up from 0.071 to 0.118 µg /mL (Rh. jostii СА-6) and from 0.055 to 0.219 µg /mL (P. megaterium Ср-1).

Abstract In order to investigate the influence of biological and chemical fertilisers on morphological traits, yield and yield components of safflower (Carthamus tinctorius L.), a field experiment was conducted in Maragheh (37°23' N; 46°16' E), in north western Iran, for one year in the 2014 growing season. The effect of seven treatments was evaluated: T1 - control (no fertiliser application), T2 - seed inoculation with P biofertiliser (contains phosphate solubilising bacteria; Pantoea agglomerans strain P5 and Pseudomonas putida strain P13), T3 - seed inoculation with N biofertiliser (contains Azotobacter vinelandii strain O4), T4 - foliar application of iron chelate, T5 - soil application of complete NPK, T6: foliar application of manganese chelate, and T7 - foliar application of zinc sulphate. The result showed that although application of N biofertiliser did not have a significant effect on the evaluated traits, P biofertiliser slightly improved grain yield. However, the application of complete NPK fertiliser improved most of the traits, compared to the control and biofertiliser treatment. The best performance was obtained by foliar application of manganese chelate and zinc sulphate. The results showed that micronutrient-deficiencies have to be managed to unlock the potential yield of safflower in semiarid production systems.
