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.

Capsicum Annuum L

Plant growth promoting bacteria are known to directly or indirectly influence the development and yield of plants. Studies that show the biotechnological potential of these bacteria as biofertilizers are thus important. The objective of this study was to evaluate the growth capacities of strains M2-7 and LYA12 and define whether their interactions with Capsicum annuum L. increases production. The hypothesis was that the Bacillus licheniformis strains have capacities to promote growth and yield of Capsicum annuum L. First, these strains were evaluated in vitro in selective culture media to detect those direct or indirect mechanisms for plant growth promotion. Then, the effect of both strains on seed germination and the effect of strain M2-7 were studied on the in vivo development of C. annuum L. The experimental design was completely randomized with 3 treatments and 3 repetitions. Data was analyzed with ANOVA and Tukey test (p≤0.05). Results showed that the bacterial strains were able to fix nitrogen, solubilize tricalcium phosphate Ca3 (PO4)2, produce gibberellins, lytic enzymes (amylases, proteases, lipases and esterases), biosurfactants, volatile compounds; and significantly inhibit growth (p≤0.05) of the phytopathogenic fungus Colletotrichum sp. Likewise, the strains M2-7 and LYA12 increased (p≤0.05) by 89 and 78% the seed germination of C. annuum L. M2-7 enhanced fresh weight (235%), stem diameter (308%), root weight, number and weight of fruits (316%), as compared to treatment 1 (Nitrofoska) and 3 (Control). Therefore, B. licheniformis M2-7 strain is attractive to develop the formulation of biofertilizers; aiming to improve yield of some horticultural crops towards a sustainable and ecological agriculture.

Chili Peppers

Plant growth depends on environmental conditions, management conditions and soil conditions, which is why in this research we evaluated the growth of chili peppers in a sand-based substrate, under a protected environment. The treatments evaluated were: 1) soil (control), 2) sand, 3) sand-perlite (4:1) and 4) sand-perlite (1.5:1), which were established under a completely randomized design with six replications. The species used were Capsicum annuum L. Hungarian, serrano and jalapeño types, and Capsicum pubescens Ruiz & Pav. apple type. The sand-perlite mixtures benefited the growth of the chili peppers, with respect to soil and sand. Therefore, sand-perlite mixtures should be considered as an alternative to produce chili peppers in containers.

Abstrak. Rendahnya produksi tanaman cabai merah di Indonesia antara lain disebabkan oleh serangan penyakit dan tidak tersedianya benih yang bermutu tinggi atau memiliki viabilitas yang rendah. Perlakuan benih secara hayati (Biological Seed Treatment) menggunakan rizobakteri merupakan salah satu inovasi yang dikembangkan untuk pengendalian penyakit dan pemacu pertumbuhan tanaman. Penelitian ini telah dilaksanakan di Laboratorium Ilmu dan Teknologi Benih Program Studi Agroteknologi Fakultas Pertanian Unsyiah. Penelitian dimulai sejak bulan Mei hingga Juli 2017. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola non faktorial pada percobaan I terdiri dari 18 perlakuan yang diulang sebanyak 3 kali sehingga didapatkan masing-masing 54 satuan percobaan terhadap patogen Phytophthora capsici dan 54 satuan percobaan terhadap patogen Colletotrichum capsici sehingga didapatkan 108 total satuan percobaan. Pada perobaan II menggunakan Rancangan Acak Lengkap (RAL) pola faktorial terdiri dari 19 perlakuan rizobakteri dan 2 perlakuan varietas yang diulang sebanyak 2 kali Sehingga terdapat 38 kombinasi perlakuan yang terdiri dari 48 unit percobaan dengan 25 unit tanaman di setiap perlakuan. Hasil penelitian percobaan I menunjukkan bahwa isolat SRK 5(1) yang berasal dari Desa Serulee Kayu, Kecamatan Bukit, Kabupaten Bener Meuriah mampu menekan pertumbuhan patogen C. capsici dengan nilai daya hambat 82,22% dan terhadap patogen P. capsici 71,11%. Hasil percobaan II menunjukkan bahwa rizobakteri yang efektif sebagai pemacu pertumbuhan tanaman (RPPT) terhadap proses perkecambahan benih cabai merah dalam meningkatkan viabilitas dan vigor benih terhadap potensi tumbuh maksimum dan daya berkecambah adalah isolat KTK 8(5) dimana varietas PM999 lebih baik dibandingkan varietas Taro, namun isolat yang berbeda yaitu SRK 5(1), HWI 4(1) dan BS3 5(3) mampu meningkatkan indeks vigor pada varietas Taro yang lebih tinggi dibandingkan dengan varietas PM999. Sedangkan pengaruh perlakuan rizobakteri terhadap pertumbuhan bibit cabai merah belum menunjukkan peningkatan yang signifikan terhadap dua varietas yang dicobakan.Effectiveness of rizobacteria inhibition to Pathogens Carried Seed In vitro and its role as plant growth promoting to seed viability and vigor in two varieties red chili pepper (Capsicum annuum L.)Abstract. The low production of red pepper plants in Indonesia is partly caused by disease attacks and unavailability of high quality seeds or have low viability. Biological Seed Treatment using rhizobacteria is one of the innovations developed for disease control and growth of plants. This research has been carried out in Agricultural Science and Technology Laboratory of Agrotechnology Study Program Faculty of Agriculture Unsyiah. The study was conducted from May to July 2017. This study used a Completely Randomized Design (RAL) of non factorial pattern in experiment I consisted of 18 treatments repeated 3 times so that each of 54 experiments on pathogenic Phytophthora capsici and 54 units of experiments was obtained pathogen Colletotrichum capsici to obtain 108 total unit of experiment. In the second experiment using Completely Randomized Design (RAL) the factorial pattern consisted of 19 rizobacterial treatments and 2 repeated treatments of varieties 2 times. Thus there were 38 treatment combinations consisting of 48 experimental units with 25 plant units in each treatment. The result of experiment I showed that isolate SRK 5 (1) from Serulee Kayu Village, Bukit Subdistrict, Bener Meuriah Regency was able to suppress the growth of C. capsici pathogens with 82.22% inhibition and against P. capsici 71.11% . The results of experiment II showed that rizobakteri effective as plant growth enhancer (RPPT) to germination process of red chilli seedlings in increasing seed viability and vigor to maximum growth potential and germination is isolate KTK 8 (5) where the varieties of PM999 is better than Taro varieties, but the different isolates of SRK 5 (1), HWI 4 (1) and BS3 5 (3) were able to increase the vigor index on higher Taro varieties compared to the PM999 varieties. While the effect of rizobacterial treatment on the growth of red chili seedlings has not shown a significant increase in the two varieties tested.

The influence of plant-growth-promoting bacteria (Azospirillum brasilense and Pantoea dispersa) on sweet pepper plants (Capsicum annuum L.) under limited N supply was studied. Inoculation did not affect leaf CO2 assimilation, Ci/Ca (the ratio of the intercellular to the ambient CO2 concentration), concentration of chlorophylls, chlorophyll fluorescence (maximum quantum efficiency of PSII) or SPAD readings. Total plant dry weight was significantly reduced in both inoculated and non-inoculated plants when the N supply was reduced from 12 (control) to 7 mM, whilst the NO3− and total-N concentrations in the leaves were not significantly affected by inoculation. Inoculation did not affect marketable fruit yield or the pigments (chlorophylls, lycopene and β-carotene) and carbohydrate (sucrose, glucose and fructose) contents in the fruits but flavonoids and anthocyanins were increased significantly by the addition of the bacteria, relative to non-inoculated plants under limited N supply. Key words: Plant-growth-promoting bacteria, Capsicum annuum L., soilless, photosynthesis, chlorophylls, flavonoids

Marketable Fruit

Raw seed, primed seed, and transplants were compared for effects on stand establishment, plant morphology, and yield of paprika pepper (Capsicum annuum L.) Raw seed seemed satisfactory for stand establishment, although primed seed had the potential to provide better initial stands. When populations were equalized, there were few differences in plant growth, plant morphology, or fruit yield attributed to seed treatment. Morphology of plants established by direct seeding generally was favorable for mechanical harvest. Use of transplants did not result in higher marketable fruit yields than direct seeding in two out of three years. When compared to plants established by direct seeding, three trends were consistent across all three years for plants established by transplanting: a) they were more massive: b) they had larger vertical fruiting planes: and c) they had more branches. These traits would increase the difficulty of mechanical harvest and would create the potential for more trash in the harvested product. Thus, transplanting is not recommended for stand establishment of paprika intended for mechanical harvest.
