A red chili plant (Capsicum spp.) is one of the horticultural commodities in Indonesia which has good economic value, so it has priority to be developed. Agriculture practices in Java island have partly switched to coastal areas which have characteristics of saline soils. Saline soils are alkaline and nutrient-poor, especially essential nutrients such as P and N. One way to restore fertility in saline soils used beneficial and fertilizing bacteria such as PGPR. Plant growth-promoting rhizobacteria (PGPR) are free-living, soil-borne bacteria, which are capable of enhancing the growth of the plant either directly or indirectly. The objectives of this research were to determain the effect of PGPR isolates to the growth of red chili plants in saline sandy soil and to determine the best PGPR isolate capable to improve the growth of red chili plant in saline sandy soil. The result showed that the inoculation of rhizobacteria significantly affected to plant height and root length of the red chili plant (Capsicum annum). The combination of 3 PGPR isolates (Azospirillum PSA 10, Azotobacter PSA 8, and Marinococcus PSA 1) was the best result in increasing the height and root length of the chili plant (Capsicum annum).

ABSTRAKKerusakan tanaman oleh jamur patogen sering ditemukan di pesemaian maupun di lapangan. Pengendalian biologis menawarkan alternatif yang menjanjikan untuk mengelola penyakit pada tanaman karena sifatnya yang ramah lingkungan dibandingkan dengan pestisida. Tujuan penelitian adalah menguji daya antagonisme Trichoderma harzianum dan Azotobacter chroococcum pada media bahan organik padat "TRIAZOTE" yang telah disimpan selama lima bulan terhadap patogen R. solani, S. rolfsii, dan F. oxysporium. Perlakuan secara in-vitro menguji daya antagonisme T. harzianum dan A. chroococcum masing-masing terhadap pertumbuhan patogen R. solani, S. rolfsii, dan F. oxysporum. Hasil penelitian menunjukkan bahwa T. harzianum pada "TRIAZOTE" yang telah disimpan selama lima bulan dapat menghambat pertumbuhan patogen R. solani, S. rolfsii, dan F. oxysporum masing-masing sebesar 54,57%, 66,22%, dan 68,57%. Sedangkan A. chroococcum tidak secara signifikan menghambat pertumbuhan patogen R. solani (11,02%), S. rolfsii (9,09%) dan F. oxyprorum (10,99%). Untuk mengendalikan penyakit pada tanaman khsusnya yang disebabkan oleh patogen tular tanah R. solani, S. rolfsii dan F. oxyprorum, dapat menggunakan pupuk hayati "TRIAZOTE" meskipun telah disimpan selama lima bulan.

<p>Low nitrogen content in soil is usually overcome by chemical fertilization. After long application period, high-dose and intensive use of N fertilizers can cause ammonia volatilization and nitrates accumulation in soil. In sustainable agriculture, the use of bacterial inoculant integrated with nutrient management system has a role in soil health and productivity. Azotobacter-based biofertilizer is suggested as a chemical nitrogen fertilizer substitute or addition in crop production to improve available nutrients in the soil, provide some metabolites during plant growth, and minimize fertilizer doses. The objective of this literature reviewed paper is to discuss the role of Azotobacter in agriculture; and the prospective of Azotobacter to increase yield and substitute the chemical fertilizer in food crops production. The results revealed that mechanisms by Azotobacter in plant growth enhancement are as biofertilizer, biostimulant, and bioprotectant. Nitrogen fixation by Azotobacter is the mechanism to provide available nitrogen for uptake by roots. Azotobacter stimulates plant growth through phytohormones synthesis; indole acetic acid, cytokinins, and gibberellins are detected in the liquid culture of Azotobacter. An indirect effect of Azotobacter is exopolysaccharide production and plant protection. Inoculation of Azotobacter in the field integrated with organic matter and reduced chemical fertilizer are reported to improve plant growth and yield.</p>
