Influence of integrated phosphorus supply and plant growth promoting rhizobacteria on growth, nodulation, yield and nutrient uptake in Phaseolus vulgaris

Abstract

To guarantee a sufficient phosphorus supply for plants, a rapid and permanent mobilization of phosphorus from the labile phosphorus fractions is necessary, because phosphorus concentrations in soil solution are generally low. Several plant growth-promoting rhizobacteria (PGPR) have shown potential to enhance phosphorus solublization and nodulation of legumes when co-inoculated with Rhizobium. This investigation was undertaken to assess the feasibility and compatibility of two mineral phosphorus fertilizers; diammonium phosphate (DAP), triple super phosphate (TSP), poultry manure (PM) and two PGPR strains on the growth, nodulation, yield, nutrient uptake and protein content of common bean (Phaseolus vulgaris) under deficient phosphorus supply. Integrated application of mineral phosphorus (P), PM and PGPR significantly increased shoot height, shoot fresh weight, shoot dry weight and leaf chlorophyll content by 67, 160, 51 and 106%, respectively, while increase in root length, root fresh weight and root dry weight was 79, 161, and 187%, respectively, over unfertilized control without PGPR application. Integrated use of different P sources and PGPR also increased number of nodules per plant, nodule fresh weight and nodule dry weight by 158, 107 and 168% over the control. Treatment with PGPR significantly increased number of pods per plant and grain yield by 224 and 96%, respectively over the control. Co-inoculation with Bradyrhizobium sp. strain MN-S and Agrobacterium sp. strain Ca-18 demonstrated twofold increase in the proportion of nitrogen (N) and P uptake as well as protein content of the common bean grain was increases by 48%. Therefore, application of PGPR with low P fertilizer rates and PM could be a viable supplementary strategy for maximum benefits in terms of cost of production and sustaining productivity.

The Common bean (Phaselous vulgaris L.) Response to Different Levels of Organic and Inorganic Fertilizers

“…While minimum GY was documented in control (1600.00bc) as shown in Fig 3 (g). The findings of this study confirm with the results of Zafar et al [34], Maman et al [36] and Baghdadi et al [38] who reported that the integrated application of organic and inorganic fertilizer produced better yield and yield components compare to individual use.…”

“…Based on the results of investigations, it was found that the combine application of organic and inorganic fertilizer significantly increased the crops yield compare to isolat application of them [17,34,35,36], but Santosa et al [37] founded in his research that the use of 50: 150: 50 kg ha -1 dose of NPK, produced the high value of plant height (PH), pods per plant (PP) and growth attributes on grean bean against to the application of cow manure and control.…”

Influence of native rhizobacteria co‐inoculation and formulation of bacterial inoculants on the growth and yield of common bean (Phaseolus vulgaris L.)

“…Similar to the present findings, a previous study by Benidire et al (2017) has reported that co‐inoculation of rhizobial strains compared to single inoculation improved growth parameters of common bean under field conditions. Similarly, Zafar (2011) reported that co‐inoculation with rhizobia and PGPRs enhanced the shoot and root dry weight of common bean. Matse et al (2020) demonstrated that both the individual inoculation of two Rhizobium strains and their co‐inoculation with the two PGPR, B. aryabhattai strain Sb and A. vinelandii strain G31, significantly increased the dry weight of white clover.…”

“…Furthermore, Raklami et al (2019) reported the positive effect of co-inoculation with rhizobia and PGPRs on nodulation of faba bean. Several other studies on the co-inoculation of PGPRs along with rhizobia have been shown to enhance nodulation and symbiotic interaction of many legumes (Fatnassi et al, 2015;Kong et al, 2017;Swarnalakshmi et al, 2020;Zafar, 2011).…”

Influence of Increase in Phosphorus Supply on Agronomic, Phenological, and Physiological Performance of Two Common Bean Breeding Lines Grown in Acidic Soil under High Temperature Stress Conditions

“…The SEF 10 vegetative and reproductive processes were not significantly affected by high temperatures, and the penalty observed in pod and grain formation was lower than that observed in BFS 10. SEF 10 responded to the increase in P supply with an increase in pod and grain production, thus allocating more energy to seed formation, so that seed viability was not drastically affected [ 54 ]. Increased P supply alleviated, to some extent, the effects of high temperature stress on reproductive organ development in both bean lines, but the effects seem to be a greater in regards to the BFS 10 compared to the SEF 10 line.…”
