| Abstract: | This study aims was to determine the potential of water fern Azolla pinnata combined with biofertilizer (Azotobacter chroococcum N2-fixing bacteria and Pseudomonas cepaceae phosphate solubilizing bacteria) in improving N and P content of the soil, and yield of paddy rice crops. This research was conducted in lowland of Agricultural Research and Development School (Sanggar Penelitian Latihan dan Pengembangan Pertanian or SPLPP), Ciparay Bandung regency. The experimental design used was randomized block design with factorial pattern that consisted of two factors. The first factor was A. pinnata (A) consisted of two levels, without A. pinnata and with A. pinnata as much as 3 tons ha-1. The second factor was the biological fertilizer (H) consisted of 3 levels with doses of 0, 5, and 10 L ha-1. The results showed that A. pinnata and biofertilizer do not interact to increase soil N and P, as well as lowland rice crops. However, A. pinnata independently increased the content of available N and P soil, while the biofertilizer at 10 L ha-1 was able to increase the available soil-P content compared with controls. The combination of A. pinnata and biofertilizers have not been able to increase the yield of rice significantly, but could increase the yield of rice by 16.1 % compared to the average yield of rice in paddy field locations in Ciparay Bandung regency. |
