“…The reasons for increase in plant height under inoculation and N fertilizer could be due to the increased vegetative growth with applied N and nitrogen fixation. This result is in line with the report of Kubota et al (2008) who stated that plant height of soybean was increase with N in the presence of Rhizobium inoculants. Other authors also reported similar results from researches conducted on chickpea and faba bean, El-Wakeil and El-Sabai (2007) indicating that Rhizobium inoculation significantly increased plant height.…”

Common bean (Phaseolus vulgaris L.) is one of the most important and widely cultivated pulse crops in most developing countries. However, its cultivation is globally constrained mainly by low soil fertility and lack of improved agronomic practices. A field experiment was conducted at Hawassa University College of Agriculture, Hawassa Southern Ethiopia to determine the effect of N fertilization and Rhizobium phaseoli strain HB-429 inoculation on growth, nodulation, yield and yield components of common bean variety Hawassa Dume. The experiment was laid out as a randomized complete block design with three replications. Results showed significant increase in growth, nodulation, yield and yield components in plants inoculated with Rhizobium strain HB-429 over the control. Thus, from the results of this study, it can be concluded that Rhizobium inoculation with strain HB-429 is the best performing treatment to be recommended for profitable grain yield of common bean at the Hawassa and other similar areas.

“…Average over two N levels, increase in plant height, SDW, root length and RDW due to combine application of N with RI was 8, 7, 13 and 3% compared to their respective control. Kubota et al (2008) and Diep et al (2002) obtained increased growth of soybean fertilized with N in the presence of RI. Benefits of inoculation and N application are generally thought to be higher if N is a limiting factor, or deficient in soil (Peoples and Craswell, 1992) or because of large N demand of high yielding cultivars (Dashti et al, 1998).…”

Effect of Rhizobium inoculation and NP fertilization on growth, yield and nodulation of soybean (Glycine max L.) in the sub-humid hilly region of Rawalakot Azad This research experiment was conducted to examine the effect of Rhizobium inoculation (RI) and P fertilization (P) on nodulation, growth and yield characteristics of soybean grown in the presence of starter N fertilizer (N). Treatments included: i) 02 levels of RI (RI 0, RI 1 ), ii) 02 levels of P (P 0 , P 1 that is, P 2 O 5 @ 90 kg ha -1 ) iii) 03 levels of N (N 0 , N 1 and N 2 that is, N at of 25 and 50 kg N ha -1 ) iv) 03 replication. Results of the experiment revealed that total number of nodules increased from 73 in the un-inoculated control to 125 and 95 following the application of RI and P representing 70 and 30% increase over control. N supply did not affect the number of nodules; however, combination of RI and P with 25 kg N ha -1 (RI 1 P 1 N 1 ) produced the highest number of nodules (152). RI, P, N and their combinations increased shoot and root biomass. Seed yield in the control was 767 kg ha -1 that significantly increased to 1081, 907 and 940 kg ha -1 following the application of RI, P and N demonstrating a 41, 18 and 23% increase over control. The highest seed yield of 1208 kg ha -1 was recorded in the combine treatment of RI 1 P 1 N 1 indicating 57% increase over control. Relative increase in dry matter yield due to RI, P and N was 63, 46 and 49%. Seed protein content in different treatments ranged between 33 -40% while oil content ranged between 13 -18%. Application of RI, P and their combinations increased protein content by 6 -22% while increase in oil content was 12 -35%. Concentrations of N and P in plants and their uptake was significantly increased and relative increase in N uptake due to RI, P and K was 77, 21 and 31% , respectively, while the corresponding increase in P uptake was 79, 92 and 56%. It was found that the efficiency of RI and P fertilization increased substantially with the application of 25 kg N ha -1 but the efficiency decreased when N supply increased from 25 kg N ha -1 to 50 kg N ha -1 . The results demonstrate the potential benefits of using Rhizobium inoculation and P fertilization with reduced level of N as starter fertilizer in order to achieve plant-growth promotion, increased nodulation and seed yield of soybean.

“…Benefits of microbial seed coating on crop yield can be of short-term or null according to the growing conditions (Kubota et al, 2008). In fact, not all published research shows positive effects on plant performance of PBM inoculation via seed coating.…”

Seed Coating: A Tool for Delivering Beneficial Microbes to Agricultural Crops

Plant beneficial microbes (PBMs), such as plant growth-promoting bacteria, rhizobia, arbuscular mycorrhizal fungi, and Trichoderma, can reduce the use of agrochemicals and increase plant yield, nutrition, and tolerance to biotic–abiotic stresses. Yet, large-scale applications of PBM have been hampered by the high amounts of inoculum per plant or per cultivation area needed for successful colonization and consequently the economic feasibility. Seed coating, a process that consists in covering seeds with low amounts of exogenous materials, is gaining attention as an efficient delivery system for PBM. Microbial seed coating comprises the use of a binder, in some cases a filler, mixed with inocula, and can be done using simple mixing equipment (e.g., cement mixer) or more specialized/sophisticated apparatus (e.g., fluidized bed). Binders/fillers can be used to extend microbial survival. The most reported types of seed coating are seed dressing, film coating, and pelleting. Tested in more than 50 plant species with seeds of different dimensions, forms, textures, and germination types (e.g., cereals, vegetables, fruits, pulses, and other legumes), seed coating has been studied using various species of plant growth-promoting bacteria, rhizobia, Trichoderma, and to a lesser extent mycorrhizal fungi. Most of the studies regarding PBM applied via seed coating are aimed at promoting crop growth, yield, and crop protection against pathogens. Studies have shown that coating seeds with PBM can assist crops in improving seedling establishment and germination or achieving high yields and food quality, under reduced chemical fertilization. The right combination of biological control agents applied via seed coating can be a powerful tool against a wide number of diseases and pathogens. Less frequently, studies report seed coating being used for adaptation and protection of crops under abiotic stresses. Notwithstanding the promising results, there are still challenges mainly related with the scaling up from the laboratory to the field and proper formulation, including efficient microbial combinations and coating materials that can result in extended shelf-life of both seeds and coated PBM. These limitations need to be addressed and overcome in order to allow a wider use of seed coating as a cost-effective delivery method for PBM in sustainable agricultural systems.
