Nutrient availability is very significant in supporting plant growth. The low content of organic fertilizers and existing minerals appear as the primary limiting factors for soybean cultivation on acid soils. Therefore, the purpose of this research is to determine the effect of organic fertilizers and Plant Growth Promoting Rhizobacteria (PGPR) on plant growth and yield. A completely randomized block design (CRBD) factorial with three replications was employed, where the first variable involved the chicken and cow composts as well as Tithonia green fertilizer. Meanwhile, the second referred to PGPR at 0, 5, 10 and 15 ml.L<sup>-1</sup>. The results showed no interaction between the application of organic fertilizers and PGPR on soybean growth as well as the yield. Furthermore, the cow manure treatment of 10 t.ha<sup>-1</sup> reportedly increased the total dry weight and sample growth rate by 0.44 and 0.86%, respectively, compared to the chicken manure at similar composition. Also, 10 ml.L<sup>-1</sup> of PGPR was known to improve the pod quantity per plant and harvest index by 0.58 and 2.66% harvest index, correspondingly, than without PGPR.

The marginal sandy coastal land should be utilized to maintain production level of shallot. But for increasing the productivity of sandy coastal land, in the shallot cultivation should be applied biological fertilizers, such as Plant Growth Promoting Rhizobacteria (PGPR). The purpose of this research was to obtain the most effective isolate of PGPR (Plant Growth Promoting Rhizobacteria) to the growth of three shallot cultivars in the sandy coastal land. The research had been conducted in August-November 2015 at Samas sandy coastal land, Bantul. The Factorial treatments were assigned in Randomized Complete Block Design with three blocks as replications. The first factor was shallot cultivars consisted of Crok, Tiron and Tuk-tuk, while the second factor was the PGPR suspension, i.e. control (without PGPR), PGPR isolates BP25.2 (Bacillus methylotrophicus), BP25.6 (Bacillus amyloliquofaciens), BP25.7 (Bacillus subtilis), BrSM 4 (Burkholderiacepacia), and BrSG 5 (Burkholderiaseminalis). The data of growth and yield were analyzed using ANOVA with α = 5%, then followed by DMRT α 5% . The result showed that Tiron cultivar was able to grow in sandy coastal land, proven from its good germination, high number of bulb, high fresh weight, and dry weight of bulb. Meanwhile, BP25.2 isolate was able to increase seed growth simultaneously of Tiron cultivar and BrSM 4 isolate was able to increase the chlorophyll content of Tuk-tuk cultivars.

The low productivity of cocoa plantations in Indonesia is partly due to the low quality of seeds, which refers to the impeded growth of cultivated cocoa nurseries. Seed is the initial growth of plants so the importance of giving special treatment to seeds will refer to better seed growth. Provision of Plant Growth Promoting Rhizobacteria (PGPR) microbes can produce indoleacetic acid (IAA) in plants to improve the quality of plant growth. This study aims to determine the effectiveness of the provision of Plant Growth Promoting Rhizobacteria bamboo rhizosphere against cocoa seed germination. The study was carried out in the farmer group garden, Gantarangkeke District, Bantaeng. This study was arranged in the form of a two-factor factorial design (F2F) in a randomized block design (RBD). The use of cocoa seed type as the first factor consisted of GTB (Gantarangkeke Bantaeng) local cocoa seed and MCC 01 cocoa seed and seed immersion treatment at PGPR rhizosphere bamboo concentration as the second factor consisting of 0% (control) concentration, 5%, 10 % and 15%. The results obtained indicate that administration of seeds with bamboo rhizosphere PGPR affects the germination (100.00%), the speed of seed growth (7.14%/etmal), as well as on abnormal seeds (10.00%). So that the provision of bamboo rhizosphere PGPR on cocoa seeds has an effective influence on seed germination and cocoa seedling development.

Plant growth-promoting rhizobacteria with multiple growth-promoting traits play a significant role in soil to improve soil health, crop growth and yield. Recent research studies have focused on the integration of organic amendments with plant growth-promoting rhizobacteria (PGPR) to enhance soil fertility and reduce the hazardous effects of chemical fertilizers. This study aims to evaluate the integrated application of biochar, compost, fruit and vegetable waste, and Bacillus subtilis (SMBL 1) to soil in sole application and in combined form. The study comprises eight treatments—four treatments without inoculation and four treatments with SMBL 1 inoculation in a completely randomized design (CRD), under factorial settings with four replications. The results indicate that the integrated treatments significantly improved okra growth and yield compared with sole applications. The integration of SMBL 1 with biochar showed significant improvements in plant height, root length, leaf chlorophyll a and b, leaf relative water content, fruit weight, diameter and length by 29, 29, 50, 53.3, 4.3, 44.7 and 40.4%, respectively, compared with control. Similarly, fruit N, P and K contents were improved by 33, 52.7 and 25.6% and Fe and Zn in shoot were 37.1 and 35.6%, respectively, compared with control. The results of this study reveal that the integration of SMBL 1 with organic amendments is an effective approach to the sustainable production of okra.
