Abstract The research aims to find out the effect of pre-germination treatment seeds using rhizobacteria as plant growth promotion of two varieties of red chili peppers in the field. The experiment used a randomized design of factorial groups. Factors studied were varieties (V) and rhizobacteria types (R). The variety factor consists of 2 varieties namely PM999 (V1) and Kiyo F1 (V2). While the type of rhizobacteria factor tried consists of 8 treatment, namely, control (R0), Azotobacter sp. (R1), B. megaterium (R2), P. atmuta (R3), B. alvei (R4), Flavobacterium sp. (R5), B. coagulans (R6), B. firmus (R7) and B. pilymixa (Rs). Each treatment was repeated 3 times, so there were 48 experimental units. Each unit of experiment is represented by 5 sample plants. The data was analyzed using ANOVA and continued with DMRT test at real level α = 0.05. The results showed that vegetative growth and production of chili plants until the age of 45 days after planting in each variety is not dependent on the pre-germination treatment of seeds with rhizobacteria. But the varieties of chili plants used affect vegetative growth and production. PM999 varieties are superior to the Kiyo F1 variety. Pre-germination treatment of seeds using rhizobacteria is relatively effective in improving vegetative growth and yield of chili plants. Among the 8 isolates rizobacteria isolate Azotobacter sp., B. megaterium, B. coagulants, Flavobacterium sp., and P. atmuta relatively effective to provide an increased effect on the growth and production of chili plants.

Salinity is one of the abiotic stresses that affect crop growth and productivity in arid and semi-arid regions. Unfortunately, there are few known methods to mitigate the deleterious impacts of salt stress on the development and yield of vegetable crops. Blue-green algae (cyanobacteria) are endowed with the potential to curb the negative impacts of salt stress as they are characterized by biostimulant properties. The present work aimed to investigate the effects of Roholtiella sp. as a foliar extract on the growth characteristics, physiological and biochemical responses of bell pepper (Capsicum annuum L.) plants under varying levels of salinity conditions. A soilless water experiment was carried out in a greenhouse where bell pepper seedlings were grown under five salt concentrations (0, 50, 200, 150, and 200 mM of NaCl). Growth characteristics, pigments content, relative water content, and antioxidant activity (CAT) were determined. Our results showed that growth parameters, relative water content (RWC), chlorophyll a & b concentrations under salinity conditions were negatively affected at the highest concentration (200 mM). Interestingly, the application of Roholtiella sp. foliar extract enhanced the plant growth characteristics as shoot length increased by 17.014%, fresh weight by 39.15%, dry and weight by 31.02%, at various salt treatments. Moreover, chlorophyll a and b increased significantly compared with seedlings sprayed with water. Similarly, RWC exhibited a significant increase (92.05%) compared with plants sprayed with water. In addition, antioxidants activities and accumulation of proline were improved in Roholtella sp. extract foliar sprayed seedlings compared to the plants foliar sprayed with water. Conclusively, at the expiration of our study, the Rohotiella sp. extract-treated plants were found to be more efficient in mitigating the deleterious effects caused by the salinity conditions which is an indication of an enhancement potential of tolerating salt-stressed plants when compared to the control group.

Salah satu strategi efisiensi dalam budidaya sayuran adalah menekan biaya produksi pada setiap usaha taninya dengan menggunakan pupuk yang tepat dan sesuai dengan kebutuhan optimal. Salah satu upaya pemupukan berimbang menggunakan Kombinasi POC sabut kelapa dan NPK. Penelitian ini bertujuan untuk menganalisis kombinasi POC sabut kelapa dan NPK terhadap pertumbuhan dan hasil tanaman cabai merah (Capsicum annuum L.). Penelitian ini dilaksanakan pada bulan april sampai bulan agustus 2020 di desa kertabasuki, kecamatan maja, kabupaten majalengka. Penelitian ini menggunakan rancangan acak kelompok (RAK) non faktorial dengan sembilan perlakuan dengan tiga kali ulangan. Faktor kombinasi pupuk yang diaplikasikan yaitu : A (0 ml POC + 0g NPK), B (50 ml POC + 5g NPK), C (50 ml POC + 0g NPK), D (100      ml POC + 5g NPK), E (100 ml POC + 0g NPK), F (150 ml POC + 5g NPK), G (150 ml POC + 0g NPK), H (200 ml POC + 5g NPK) dan I (200 ml POC + 0g NPK). Hasil penelitian menunjukan bahwa kombinasi POC sabut kelapa dan NPK berpengaruh nyata pada pertumbuhan dan hasil tanaman cabai. Kombinasi 200 ml POC tanpa NPK memberikan hasil terbaik pada tinggi tanaman 9 mst diameter dan bobo buah cabai.
