TL;DR: The interaction effect between the biofertilizers and levels of phosphorous on number of suckers per plant was found to be non-significant during both the years of experimentation.
Abstract: A pot experiment was conducted in the screen-house of the Department of Horticulture, College of Agriculture, CCS Haryana Agricultural University, Hisar during 2011–12 and 2012–13 to investigate the potential effect of biofertilizers (PSB and mycorrhiza) and different levels of phosphorus (0, 10, 15 and 20 g/m2) on growth, yield and quality of chrysanthemum. The conjunctive effect of biofertilizers and different levels of phosphorus was found to be significant for both the years. The maximum plant height (31.77 and 33.33 cm), fresh weight of plant (100.90 and 96.77 g) and dry weight of plant (10.85 and 10.15 g) were recorded with PSB + phosphorus 15 g/m2 in the year 2011–12 and 2012–13, respectively. The minimum number of days taken for bud initiation (61.67 and 63.33 days) and number of days to first flowering (75.00 and 75.67 days) were also obtained with PSB + phosphorus 15 g/m2 in both the years, respectively. The maximum number of buds per plant (32.33 and 32.00), number of flowers per plant (29.00 and 29.33), the longest flower stalk (6.33 and 6.33 cm) were noticed with PSB + phosphorus 15 g/m2 in the year 2011–12 and 2012–13, respectively. The maximum number of days taken for bud initiation (79.00 and 80.33 days) was recorded with mycorrhiza application (alone) during both the years, respectively. The interaction effect between the biofertilizers and levels of phosphorous on number of suckers per plant was found to be non-significant during both the years of experimentation.

TL;DR: In this paper, a review of the role of PSM in the management of ornamental diseases is discussed and considered and several PSM for future researches aiming to improve the health and quality of ornamentals grown in different production systems.
Abstract: Ornamental plants play an important role in human society since flowers are considered a vital component due to their beauty, texture, color, shape and fragrance. To produce high quality ornamentals, growers in general have intensified the use of agrochemicals without considering their deleterious impact on floral attributes. Also, the agrochemicals (including fertilizers and pesticides) used in floriculture are expensive and their excessive application results in emergence of pathogens resistant to such chemicals. It has, therefore, become imperative to develop renewable, inexpensive and eco-friendly fertilizers without producing any disturbing impact on quality of ornamentals. In this regard, phosphate solubilizing microorganisms (PSM) among plant growth promoting rhizobacteria have been identified as an efficient alternative to agrochemicals in floriculture. Even though, there are adequate reports on the effect of PSM on growth and development of numerous plants, information on the impact of PSM on production and quality of ornamental plants is, however, critically scarce. Considering these gaps and success of PSM application in floriculture achieved so far, efforts have been directed to highlight the impact of PSM on the production of ornamentals grown distinctively in different production systems. Also, the role of PSM in the management of ornamental diseases is discussed and considered. The review will conclude by identifying several PSM for future researches aiming to improve the health and quality of ornamentals grown in different production systems. Use of PSM is also likely to reduce the use of chemicals in floriculture.

TL;DR: The results obtained clearly show that of all the species of mycorrhizae taken under consideration, Glomus mosseae was found to perform better in terms of nutrient acquisition and uptake of P to plant and may be due to the higher solubilization power ofglomus mossae for soil nutrients than other species.
Abstract: An investigation was carried out to evaluate the response of selected species of mycorrhizae for nutrient acquisition and phosphorus uptake by maize in an alluvial soils of Bihar. The study was undertaken during 2013 wet season (July to December) in a net-house at Bihar Agricultural University. Six treatments along with a control treatment were maintained with three replications for the experiment. Five species of AM fungi collected from TERI (The Energy and Resources Institute) along with a local species from long term litchi orchard (Muzaffarpur), were evaluated on the basis of nutrient acquisition in the soil rhizospeheric region for maize crop. The results obtained clearly show that of all the species of mycorrhizae taken under consideration, Glomus mosseae was found to perform better in terms of nutrient acquisition and uptake of P to plant. The maximum P concentration (7.65 mg kg-1), organic carbon (0.60%) and Zn Concentration (6.48 mg kg-1) and P uptake (was also found with the application of G. mosseae. The AM (Arbuscular Mycorrhiza) species significantly increased the released of P and micronutrients in the soil of rhizospheric region of maize plant. The beneficial effect was more pronounced for the treatment in case of Glomus mossae among all the other species used. This may be due to the higher solubilization power of Glomus mossae for soil nutrients than other species. Art ic le History

TL;DR: The obtained results revealed that the inoculation of plants with biofertilizers and recommended dose of superphosphate significantly improved the growth parameters, thus facilitating P acquisition and improving plant growth.
Abstract: A pot experiment was conducted to investigate the potential effect of arbuscular mycorrhizal fungi (Glomus mosseae & Acaulospora laevis) and phosphate solubi- lizing bacteria (Pseudomonas fluorescens) with different levels of superphosphate on Chrysanthemum indicum L. After 100 days, different plant growth parameters such as mycorrhization's characteristics, phosphatase activity and phosphorus up- take were measured. The obtained results revealed that the inoculation of plants with biofertilizers and recommended dose of superphosphate significantly improved the growth parameters. Inoculation with A. laevis + P. fluorescens at medium con- centration of superphosphate showed maximum height, fresh and dry root weight, AM root colonization, AM spore count, alkaline phosphatase activity, acidic phos- phatase activity and the percent phosphorus uptake in shoot and root whereas root length was maximum in G. mosseae + A. laevis + P. fluorescens. Leaf area and fresh and dry shoot weight were maximum in the treatment (G. mosseae + A. laevis + P. fluorescens) at low concentration of superphosphate. The use of AMF increased nu- trient acquisition from an organic fertilizer source by enhancing acidic phosphatase (ACP) and alkaline phosphatase (ALP) activity, thus facilitating P acquisition and improving plant growth.

TL;DR: The interaction between N and P levels was non-significant for all parameters and Vegetative growth and floral parameters were not significantly influended by graded levels of P.
Abstract: The response of 5 levels of N (100, 150, 200, 250 and 300 kg/ha) and 4 levels of P (0, 100, 150 and 200 kg/ha) was studied in China aster cv. ‘Kamini’. The maximum plant height (51.91 cm), plant spread (21.27 cm), length of flower stalk (27.27 cm) and number of flowers/plant (35.22) were obtained with highest level of N application @ 300 kg/ha. Though application of N @ 200, 250 and 300 kg/ha was statistically at par with each other for above 4 important parameters. Rest of the parameters e.g., number of days taken for 100% flowering, diameter of flower and weight of 5 flowers were not significantly influenced by graded levels of N. Vegetative growth and floral parameters were not significantly influended by graded levels of P. The graded levels of N and P did not significantly influence the postharvest quality of cut flowers. The interaction between N and P levels was non-significant for all parameters.

TL;DR: Results revealed that the application of bio-fertilizer and phosphorus was significant on most characters in 1% probability level, and the interaction effect was not significant on studied characters except for total shoot phosphorus and the number of leaf per plant.
Abstract: The present investigation was conducted to study the effect of bio-fertilizer (Barvar-2) and phosphorus on quantity and quality characteristics of marigold ( Tagetes erecta L.). A factorial experiment based on randomized complete blocks design (RCBD) with four replications was carried out with two factors including methods of bio-fertilizer (Barvar-2) application (without bio-fertilizer inoculation, seed inoculation, root inoculation and seed plus root inoculation), and different levels of chemical phosphorus (100, 200, 300 and 400 mg l -1 ). In the present study, plant height, the number of leaf per plant, shoot fresh weight, shoot dry matter percentage, the content of total phosphorus of cultivation media and shoot and flower diameter were measured. Results revealed that the application of bio-fertilizer and phosphorus was significant on most characters in 1% probability level. The interaction effect of biofertilizer and phosphorus was not significant on studied characters except for total shoot phosphorus and the number of leaf per plant. The best plant height (26.87 cm), the number of leaf per plant (56.27), flower diameter (84.420 mm), shoot fresh weight (19.94 g) and total shoot phosphorus (0.353%) was obtained under inoculation of seeds and roots with bio-fertilizer × 400 mg l -1 phosphorus. Maximum of shoot dry matter (19.86%) and total medium phosphorus (0.235%) was calculated in treatments of 200 mg l -1 phosphorus without bio-fertilizer inoculation and 200 mg l -1 phosphorus with seed inoculation, respectively.
