“…The success of this midrib decomposition is demonstrated by the C organic in Table 3, which is classified as medium to high. This finding supports Faizah and Fauzan (2021), Saputra et al (2018) in salak plantation of Purwosari District -Pasuruan Regency, and Wonosalam District -Jombang Regency.…”

Salak [Salacca zalacca (Gaertn.) Voss] var. amboinensis cv. Gulapasir has been officially released by the Minister of Agriculture of the Republic of Indonesia since 1994. Salak 'Gulapasir 'is one of five types of fruit that have been designated as the superior fruit of the Bali Province. Salak 'Gulapasir' is preferred by consumers due to its specific fruit flesh taste. Salak 'Gulapasir' was propagated using seeds so that a new type of salak emerged. However, the characters of this new type of salak 'Gulapasir' are not yet known. The research objective was to obtain the superior products of Salak 'Gulapasir' both in quantity and quality. The research used a Randomized Block Design with three replications. The non-independent variable was the three of Salak 'Gulapasir' (SGP): SGP var. nangka (N), SGP var. nenas (NS), SGP var. gondok (G), and six sites, namely Karangasem: (K < 560 m asl, K 560 m to 650 m asl, and K > 650 m asl) and Tabanan: (T < 560 m asl, T 560 m to 650 m asl, T > 650 m asl). Observations were made on the agronomic characters and fruit quality. Data were analyzed using variance analysis, and if the planting location and varieties show a difference, then it is followed by the LSD test at the 5 % level. The results showed that different varieties caused different fruit weights, fruit bunches, TSS, and total acid ratio. In Karangasem and in Tabanan, SGP var. nangka grows ideally at an altitude of 560 m to 650 m asl with fruit weight per tree of 1.62 kg -1 and 1.29 kg -1 , respectively. SGP var. nenas and SGP var. gondok are ideal for cultivating at an altitude of < 560 m asl both in Karangasem and Tabanan, but the fruit production of SGP var. nenas and SGP var. gondok is higher, respectively 19.29 % and 15.31 % when planted in Karangasem, while the SGP var. nenas showed the highest number of fruit bunches -1 in six locations. Further research can be applied using sustainable salak organic agriculture to maintain soil fertility.

Maize is one of the important crop so production improvement is must be done to sufficient the needs. Plant growth promoting rhizobacteria has become a feasible, efficient and sustainable approach to increase maize productivity. This study investigated the effect of several rhizobacteria consortia formulations and bacterial density on the growth and yield of five maize cultivars in Indonesia. The experiment was carried out using a nested-split plot randomized complete block design (RCBD). The treatments consisted of two rhizobacteria consortia formulation (granule and liquid) as nested, four rhizobacterial density (0, 107, 108, and 109 cfu mL–1) as main plot, and five maize cultivars (Bisi 18, Bisi 2, Pertiwi 3, Bisi 228, and Bisi 220) as subplot. The growth and yield data were analyzed through ANOVA and by means using DMRT α 5 % to determine the best treatment. Application of rhizobacteria consortia formulation on five maize varieties did significantly affect the growth and yield of maize although bacterial density did not showed the same results. Rhizobacteria consortia with granule formulation appeared significantly higher yield performance than liquid. Pertiwi 3 tended to produce higher average yield than other varieties for both rhizobacteria consortia formulation although the varieties did not significantly contribute on ear weight variables.

“…In future research, the application of PGPR should be combined with organic fertilizer. Several researchers [36][37][38][7][8][9] stated that soil organic matter content will increase and can be used as an energy source for the growth maintenance of microorganism cells and the production of extracellular enzymes. Components of cellulose and lignocellulosic organic matter are broken down into simple carbohydrates such as glucose for growth.…”

One of several factors that could increase maize production is the use of biofertilizers produced from microorganisms. The objective of this study was to obtain a granule biofertilizer formulation with Citrobacter murliniae, Raoultella terrigana, and Enterobacter hormaechei bacteria in increasing the growth and yield of several maize cultivar. The research was conducted at the Integrated Laboratory of the Faculty of Agriculture and Animal Science, University of Muhammadiyah Malang and experimental land in Singosari Malang, East Java, Indonesia from November 2020 to April 2021. The treatments were arranged in split plot design and repeated three times. The main plot was the density of Rhizobacteria which consisted of R0 = without Rhizobacteria, R1 = density 107, R2 = density 108, and R3 = density 109. Sub-plot was maize cultivar consisted of C1: Pertiwi 3, C2: Bisi 18, C3: Bisi 2, C4: Syngenta NK 6172, and C5: Pioner P27. Each experimental unit was represented by five sample plants. Results of the study showed that the treatment of bacterial colony density on biofertilizer granules has not been able to increase the growth and yield of maize, except for the average weight of cob and weight of cob without maize on the various cultivar studied.
