A deep-rooting upland rice variety (Kinandang Patong) was evaluated for its growth response to bio-fertilization at early stages. Five non-native plant growth-promoting bacteria previously isolated from yams (Dioscorea spp.) were inoculated to upland rice under growth chamber and greenhouse conditions. Effects of the inoculation varied depending on bacterial strains and growing conditions. Growth of 14-day rice seedlings was improved by all tested bacterial strains. Under growth chamber, the strain S-333 increased plant length, shoot dry weight and nitrogen content as compared to the control, but total dry weight, nitrogen uptake, leaf chlorophyll content and number of tillers were higher with N fertilizer application. Under greenhouse conditions, most rice growth parameters were improved by inoculation with the strain S-7. The correlations between the bacterial plant-growth-promoting traits and rice growth parameters under growth chamber conditions were all negative for phosphate solubilization indexes. Our results suggest that bacterial inoculation can replace half (S-343 and S-611) of or the full (S-7) rate of chemical N fertilizer required, depending on bacterial strains and growing environments, although δ15N value in control plants was lower than in inoculated plants under growth chamber conditions, suggesting that the bacteria improve rice growth through mechanisms other than biological nitrogen fixation.

The relationship between nitrogen (N) absorption and growth in water yam (Dioscorea alata L.) is not clearly understood. A previous experiment suggested that water yam is able to grow under poor soil conditions regardless without nitrogen fertilization; however, the source of nutrition was not identified. This study aimed to identify the source of N and the percentage of plant N derived from atmospheric N2 (% Ndfa) under poor soil conditions. Experiments were carried out on Miyako Island, Okinawa Prefecture, Japan, from April 2014 to December 2015. In experiment 1, water yam growth was compared under urea application (N treatment) and without (control), while in experiment 2 urea (N treatment) or cow manure (CM treatment) application versus without (control) was compared. N and CM treatment had a positive effect on growth and tuber yield. However, while yellowish leaves were observed in control plants, they grew until harvest, and tuber yield was similar between treatments. The δ15N values of the N- and CM-treated plants suggested that N was absorbed from the urea and cow manure; however, in the control plants, the N source seems to have been atmospheric. The δ15N values further suggested that water yam grown without N absorbed 38.04% N from the air.
