The present investigation was aimed at determining the effects of biofertilizers and their pure cultures on phytohormones production, plant growth and yield. Changes in the level of phytohormones were also determined in plant leaves inoculated with biofertilizers and pure cultures used alone or in co-inoculation. In pot experiment, three biofertilizers (Biopower, Biozote & Grasimi Tika) were applied to one group of plants as seed coating treatment. To a second group, broth cultures (10 days after inoculation) of the rhizobial strains were applied to seedlings (7 days after germination). Biopower resulted in maximum IAA and GA content in plant leaves than Biozote and Grasimi Tika. IAA and GA content of Biopower were higher than that of Biozote and Grasimi Tika. Biopower inoculation also resulted in an increase in nodule numbers, root/shoot length, seed weight and yield while, Biozote treatment resulted in yield that was slightly lower than Biopower, but was at par with all other treatments. Among the rhizobial strains, MN-Slow produced maximum IAA and GA in broth culture and minimum IAA and GA were observed in strain CA-18. Co inoculation of rhizobium strains showed better results than applied singly. IAA and GA contents of leaves of treated plants were also recorded to be maximum in co-inoculation treatments.
Nitrogen levels and Rhizobium inoculation and yields of native white bean (Phaseolus vulgaris L.)
The Journal of Agriculture of the University of Puerto Rico
The combined effect of N fertilization and Rhizobium inoculation on bean (Phaseolus vulgaris L., cv. Bonita) nodulation and yield was studied in the semi-arid southern region of Puerto Rico. Six N treatments: 0, 22, 45, 90, 180 and 360 kg/ha were tested in inoculated and noninoculated plots arranged in a split-plot design with 4 replications. The application of 22 kg/ha of N in the inoculated plots increased plant nodulation 4 and 8 weeks after planting. Higher rates of N fertilization reduced the number and size of bean nodules at both sampling dates. On the other hand, dry beans consistently increased with applications of 0 to 180 kg/ha of N in the presence of Rhizobium.
Nodulation of Pole Bean (Phaseolus vulgaris L.) by Rhizobium Species of Two Cross-Inoculation Groups
Applied and Environmental Microbiology, 1982
Physiology and morphology of pole bean ( Phaseolus vulgaris L. cv Kentucky Wonder) root nodules induced by two Rhizobium species of different cross-inoculation groups have been compared. Root nodules induced by Rhizobium sp. 127E15, which is a strain of the cowpea group Rhizobium , were pinkish, had irregular shapes, and were only partially effective. Their peak acetylene reduction activity was 4.36 μmol of C 2 H 4 formed per g of fresh nodules per h at 30 days after inoculation. The effective nodules induced by Rhizobium phaseoli 127K14, which is a strain of the bean group Rhizobium , were dark red, spherical, and showed peak acetylene reduction activity of 15.95 μmol of C 2 H 4 formed per g of fresh nodules per h at 15 days after inoculation. The partial effectiveness of 127E15-induced nodules was associated with fewer infected cells, a delay in the increase of bacteroid population within the host cells, abundance of cytoplasmic vesicles in the host cells, more bacteroids within a...

Common bean is among the vital legumes cultivated for nutrition, foreign currency earnings, and income generation. Common bean production is constrained mainly by nutrient deficiencies. A field experiment was conducted at Sodo Zuria Woreda to assess the effects of blended N–P–S–B fertilizer rates and Rhizobium strain on yield and yield traits of common bean and income of farmers. Treatments were five different rates of blended NPSB fertilizer (0, 50, 100, 150, and 200 kg ha−1) and two types of Rhizobium strains (HB-A15 and HB-429 (Rhizobia etli)) and control (without inoculation). Randomized complete block design in factorial arrangement with three replications were used. Results showed that interaction of blended NPSB rate and Rhizobium strain type had significant effect on the number of effective nodule, grain yield, and above ground dry biomass. Application of 150 kg NPSB ha−1 along with inoculation of Rhizobium etli resulted in the highest grain yield (3017.7 tons ha−1). Similar...

This study was conducted to evaluate the effect of rhizobial population on the effectiveness of locally isolated elite isolates of Rhizobium on common bean at the major growing area of Eastern Ethiopia. The result showed significant effect of inoculation, the varieties and their interaction on nodulation, yield and yield traits, except for the number of seed per pod. Most of tested Rhizobium isolates significantly improved the nodule number and nodules dry weight in all soils regardless of rhizobial population. Significant increase in total biomass yield and grain yield of common bean was recorded with NSCBR-14, inorganic N-fertilized and NSCBR-(25)2 treatments in soil with a high, low and moderate rhizobial population, respectively. The highest values of most of the yield traits including NN and NDW in all experimental sites was recorded with Dursitu variety but the highest values GY and TBY with Kufanzik. Hence, the indigenous rhizobial population did not affect the effectiveness ...

Background: Effectiveness of Rhizobium inoculation is determined by common bean genotypes. Environmental factors also affect common bean genotypes-Rhizobium-symbiosis. The effect of common bean genotypes-Rhizobium strains-environment interaction on nodulation and common bean production is not well studied. Three genotypes (Dursitu, Gofta, and Kufanzik) and eight selected isolates of common bean nodulating-rhizobia with N-fertilized and control check were used for field experiments at four locations (Babile, Fedis, Haramaya, and Hirna) to evaluate the effect of genotypes-Rhizobium strains-environment interaction on the nodulation, yield and yield traits of common bean. The treatments were laid out in a randomized complete block design with three replications. Results: This study revealed that Rhizobium inoculation, the genotypes, environment and their interaction significantly (P ≤ 0.05) affected all investigated traits of common bean. Common bean genotypes Rhizobium inoculation and experimental locations significantly affected nodule number (NN) and nodule dry weight (NDW). The highest NN and NDW as compared to the uninoculated control across locations were recorded with the genotype Dursitu in all inoculation treatments. However, the result revealed the lowest mean total biomass (TBY) and grain yield (GY) over locations with the same genotype Dursitu. The highest mean grain yields of 3358.89, 3257.82, 1499.25 and 2204.82 kg ha −1 across the treatments were recorded at Haramaya, Hirna, Babile and Fedis sites, respectively, with the genotype Gofta, thereby implying that there was none specificity between common bean genotypes × locations in the study locations of eastern Ethiopia with tested common bean genotypes. None of the tested isolates produced statistically better NN, NDW, TBY, GY and total plant N accumulation consistently in all locations with all tested common bean genotypes, indicating the presence of Rhizobium strains × location specificity. Conclusion: Therefore, the result showed the need for a specific strain of Rhizobium development for common bean production in different locations.
Effect of nutrients on yield attributing character of French bean (Phaseolus vulgaris L.)
International Journal of Chemical Studies, 2020
The present investigation entitled "Effect of nutrients on yield attributing characters of French bean (Phaseolus vulgaris L.)" was carried out during Rabi, 2018-19 at Instructional Farm-II of Institute of Agricultural Sciences, Bhubaneswar. The recommended dose of fertilizer (RDF) used for French bean was 50:75:75 NPK kgha-1 along with FYM @ 15 ton ha-1, which was applied in three levels i.e. 50 %, 100 % and 150 % of the RDF with various combinations of rhizobium culture and micronutrients. The experiment was consist of twelve treatments in various combinations of different levels of fertilizer with and without rhizobium culture (30 g kg-1 of seed) and micronutrients (0.1 %).The results obtained from the present investigation indicated that the treatment receiving 50:75:75 NPK kgha-1 (100 % RDF) along with FYM @ 15 ton ha-1, rhizobium culture (30 g kg-1 of seed) and micronutrients (0.1 %) recorded significantly higher value in yield parameters of French bean var. Harsh had produced pod length (3.42 cm), maximum number of pods plant-1 (35.64), pod weight (6.7g), highest pod yield ha-1 (237.0 q). Maximum number of nodules plant-1 (99.07) was also recorded in the same treatment. Thus, it may be suggested that RDF with rhizobium culture and micronutrients application gave maximum yield in case of French bean.
