“…Meanwhile, previously, co-inoculation of PGPB during the early developmental stage on plants grown in Saemangeum reclaimed soil showed that plant growth-promoting B. iodinum RS16 and M. oryzae CBMB20 increased plant height, dry biomass accumulation and macro-nutrient accumulation of maize and a sorghum-sudangrass hybrid. Macronutrient accumulation (P, K, Ca and Mg) was higher with M. oryzae CBMB20 treatment compared to the non-inoculated treatment, while B. iodinum RS16 treatment increased N, Ca and Mg accumulation compared to the non-inoculated treatment (Kim et al, 2014). Another report found that inoculation with Actinomycetes NB 1 , AVermi7, YB6y and NB 3 in combination with a full rate of fertilization significantly increased P uptake by 80 to 136% over the non-inoculated control (Cruz et al, 2014).…”

“…Only 17% of these lands have a salinity level that is acceptable for crop cultivation and the remaining 83% of the land has been deemed unsuitable for crop growth due to high salt levels. This land also has several other drawbacks such as limited macroand micronutrients, restricted organic matter and physical and chemical properties that do not promote a good crop yield (Kim et al, 2014). Thus, these areas will require an integrated management strategy.…”

a b s t r a c tA field trial to investigate the effects of plant growth promoting bacteria (PGPB) Paenibacillus yonginensis (DCY84 T ) and/or SiO 2 seed coating on rice growth (Oryza sativa L.) was carried out on reclaimed tidal land in Taean County in South Korea. The field test was performed twice between May-October 2014 and May-October 2015, in a randomized complete block (RCB) design with three replications. Treatments consisted of: Mock, DCY84T -treated seeds, SiO 2 -coated seeds and DCY84 T -SiO 2 -treated seeds and each treatment area covered approximately 300 m 2 . During the early developmental period of rice seedlings, the SiO 2 coating without DCY84T led to the most favorable 30 DAS rice seedling parameters. Moreover, the combination of DCY84 T and SiO 2 treatments resulted in 2-fold greater fresh and dry weights of 60 DAS rice seedlings compared to Mock seedlings. DCY84T and SiO 2 , both individually and together, produced a greater grain yield and a greater total yield; specifically, DCY84T and SiO 2 treatments yielded a 73% and 70% increase in mass compared to Mock plants, respectively. Rice treated with both DCY84 T and SiO 2 treatment contained the highest amount of Al, Fe, Ca and Mg, which were 54%, 169%, 42% and 67% higher than the Mock rice, respectively. Remarkably, DCY84T treatment had the most phosphate [P], potassium [K] and total nitrogen [T-N]. DCY84T and/or SiO 2 treatment highly increased the whole kernel percentage. Thus, lower its broken kernel percentage to 9.60-24.58%. The protein content of the grain with both treatments was 7.2%, which was greater than that of the Mock grain (6.0%). The content of chlorophyll a, b and carotinoid in the rice leaves which were treated with silica and DCY84 has increased more than the mock without treatment. After harvest, the GABA content of brown rice was increased to 1.9-fold (2014), 1.5 fold (2015) compared to mock grain, respectively. Overall, DCY84T treatment and SiO 2 coating can be useful methods for promoting growth of rice under conditions of saline stress. Results from other laboratory trials and greenhouse experiments are also provided.
