Abstract

Abstract The use of saline soils as productive agricultural land poses major challenges. The utilization of nitrogen biofertilizer with halotolerant N-fixing rhizobacteria as the active material at the right dosage can increase soil productivity and support plant growth. The aim of this study was to obtain the composition of the carrier material that can maintain rhizobacteria viability, water content, and pH of nitrogen biofertilizer and to obtain the right dosage to increase the growth of rice plants in saline ecosystems. The research location was at Microbiology Laboratory of CV Bintang Asri Arthauly, Bandung and greenhouse of Jayamukti Village, Banyusari District, Karawang Regency from February to November 2020 used completely randomized design. The viability test consisted of nine treatments, while the application dosage test consisted of 13 treatments and repeated three times. The result showed that the H carrier composition (50% peat + 17.5% compost + 17.5% biochar + 5% dolomite + 5% guano + 5% nutrition) was able to maintain high viability of halotolerant N-fixing rhizobacteria compared to other treatments (10.22 x 107 CFU mL-1). Water content (34.50%) and pH level (7.9) in the composition H also meet the quality standard requirements of the biofertilizer, respectively. Nitrogen biofertilizer with H carrier composition at a dosage of 1500 g ha-1 applied to seed and nursery can increase the height and biomass of rice plants grown under saline condition. Further research is needed on the application of nitrogen biofertilizers in saline soil that can increase the effectiveness of N fertilization.Keywords: Carrier ∙ Rhizobacteria ∙ Rice ∙ Saline ecosystem ∙ Viability  AbstrakPenggunaan tanah salin sebagai lahan pertanian produktif memiliki tantangan yang besar.

Abstract

Inorganic fertilizer is a very important agricultural input to increase agricultural production. Uncalculated and continuous application of inorganic fertilizers will lead to the reduction of soil fertility and degradation of environmental quality. Therefore, a strategy is needed to support the environmental sustainability in agriculture. One of the efforts is through the production of biofertilizer and organic fertilizer from local resources. Organic fertilizer for rice plants can be made by utilizing the local water fern, Azolla pinnata. A. pinnata can be applied on rice fields as green manure by directly placing it into the soil or spread on the surface of rice fields. Organic fertilizer that made from Azolla will be more advantageous because it can be applied with biofertilizer. This study aimed to determine the formulation of Azolla based solid biofertilizer that can support the growth of functional microbial population based on the Agriculture Ministry (Permentan) standard number 70/2011. The design of the study method used was Completely Randomized Design with six replications. The treatments used were inoculant starter with 3% molasses, 3% molasses + 10% rice wash water, 3% molasses + 1% yeast extract, and 3% molasses + 10% rice wash water + 1% yeast extract. The results of this study showed that Azolla-based solids fertilizer with starter formula 3% inoculant molasses + 10% rice water + 1% yeast extract have the population of Azotobacter, Azospirillum, endophytic bacteria and phosphate solubilizing microbe were greater than 108 cfu/g dry weight. Functional microbial of solids fertilizers in all formulas used do not show the difference on inhabiting in the N-free media or Pikovskaya selective media.  Keywords: Azolla pinnata, formulation, biofertilizer, organic fertilize

Abstract

The process of microbial inoculation into plant biomass which will be decomposed needs a suitable carrier material to facilitate the application of the microorganisms to be used. Halophilic bacteria are a type of microorganism that can survive high salt levels by maintaining an osmotic balance. The bacterial consortium is a collection of bacteria that work together to form a community, to produce a significant product. The experiment aims to determine the effect of carrier composition on inoculant viability. The experiment was carried out at the laboratory CV. Bintang Asri Arthauly Bandung, West Java, Indonesia. The study used a non factorial randomized design with three replications.

Abstract

Maize (Zea mays L.) is an important food crop in Indonesia as a source of carbohydrates. The extent of land conversion reduces maize productivity. The experiment aimed to increase the growth and yield of maize in Ultisol which was carried out in the experimental garden of the West Java Horticultural and Various Seed Plant Development Center from October 2017 to March 2018. The Phosphate Solubilizing Bacteria (PSB) and organic ameliorant application test used the factorial randomized block design (RBD) method consisted of two factors. The first factor is PSB and organic ameliorant which consisted of four levels, namely b0 (without the provision of PSB and organic ameliorant), b1 (BP 107 cfu mL-1), b2 (organic ameliorant 5 tons ha-1), and b3 (PSB 107 cfu mL-1 + organic ameliorant 5 tons ha-1) and the second factor is the dosage of SP-36 fertilizer consisted of five levels, namely po (without SP-36 fertilizer), p1 (100% SP-36 fertilizer), p2 (90% SP-36 fertilizer, P3 (80% SP-36 fertilizer), and P4 (70% SP-36 fertilizer). The results showed that the application of PSB (Enterobacter ludwigii + Bulkholderia vietnamiensis + Citrobacter amalonaticus) 107 cfu mL-1 and organic ameliorant dosage of 5 tons ha-1 was able to increase plant height at age 6 Week After Planting (WAP), weight of cob with and without cornhusk, and weight of 100 seeds in the framework of increasing the growth and yield of maize on Ultisols and reduce the use of inorganic P fertilizer to 90%.

Abstract

Soil fertility is recognized as a crucial factor in supporting plant growth and productivity. The utilization of biofertilizers as environmentally friendly fertilizers is aimed at enhancing soil fertility and plant productivity. This study aims to explore the potential of local material for developing local wisdom biofertilizers (LWB) for achieving sustainable agriculture. A systematic literature review was conducted using bibliometric analysis, Preferred Reporting Items for Systematic Reviews, and Meta-Analyses (PRISMA) method, employing the Scopus search engine with the keywords "local AND wisdom AND biofertilizer" OR "biofertilizer" OR "local AND microorganism" OR "soil AND health OR crop AND productivity OR sustainable agriculture". The search yielded 704 articles, of which 11 were deemed eligible after selection. Based on the literature review, it was found that there are local materials, including fish waste, seaweed, Azolla, fruit waste, Moringa oleifera, microalga, bamboo roots, banana hump, golden snail, mangrove leaves, fruit, and vegetable waste that can be used as raw materials for LWB to improve soil health, plant growth, and productivity. The development of LWB as a new fertilizer technology faces challenges such as lack of regulations, low public trust, limited farmer awareness, weak promotion, and raw material shortages. Further research is needed to intensively study and enhance the effectiveness of LWB through enrichment using beneficial microorganisms.
