VEGETATIVE GROWTH OF RAINBOW CHILI (Capsicum annuum L.) IN THE TREATMENT OF PGPR (Plant Growth Promoting Rhizobacteria), PGPR-NPK FERTILIZER, AND PGPR-COMPOST COMBINATION

Bolivian Rainbow Chili is one of the ornamental chili varieties which is unique in the form of its colorful fruit color. The vegetative growth of ornamental chilies requires additional nutrients and the role of microorganisms to obtain optimal growth. This study aims to determine the optimal growth of rainbow chilies using the application of PGPR biological fertilizer, a combination of PGPR biological fertilizer and NPK synthetic fertilizer, as well as a combination of PGPR biological fertilizer and compost organic fertilizer. This research was conducted with a completely randomized design (CRD). The data obtained were then analyzed by ANOVA and continued with the LSD test and Duncan’s test at the 5% test stage. The results showed that the combination treatment of PGPR and compost or PGPR and NPK provided optimal vegetative growth compared to single PGPR treatment.

ABSTRAK Euchema cottonii mengandung unsur mikro dan makro nutrien, serta zat pengatur tumbuh tanaman seperti auksin, giberelin, sitokinin, dan etilen sehingga sangat berpotensi sebagai pupuk organik penyubur tanaman. Penambahan buah nanas berfungsi sebagai sumber C, P, dan K pada ekstrak pupuk rumput laut cair. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan bioaktivator PGPR (Plant Growth Promoting Rhizobacteria)dan buah nanas terhadap kandungan C-organik, nitrogen, fosfor, kalium, pH, suhu, bakteri patogen, dan organoleptik warna. Material yang digunakan dalam penelitian ini adalah E. cottonii, PGPR, dan buah nanas.. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan yaitu perlakuan kontrol (A), penambahan PGPR dan buah nanas 40% (B), penambahan PGPR dan buah nanas 50% (C), dan penambahan PGPR dan buah nanas 60% (C). Parameter yang diukur adalah C-organik, nitrogen, fosfor, kalium, pH, suhu, bakteri pathogen, dan oraganoleptik warna. Data parametrik dianalisa dengan uji ANOVA. Hasil penelitian menunjukkan bahwa penambahan buah nanas yang berbeda memberikan pengaruh nyata terhadap kadar C-organik, fosfor, dan kalium (p<0,05), sedangkan nilai nitrogen tidak berbeda nyata. Perlakuan penambahan nanas 50% akan meningkatkan kandungan nitrogen dua kali lebih besar dari pada kontrol. Perlakuan terbaik yaitu pada penambahan PGPR dan nanas 60% dengan kandungan C, P, K berturut-turut adalah 7,02%, 3,44%, dan 3,41%.

Vegetable cultivation is a promising economic activity, and vegetable consumption is important for human health due to the high nutritional content of vegetables. Vegetables are rich in vitamins, minerals, dietary fiber, and several phytochemical compounds. However, the production of vegetables is insufficient to meet the demand of the ever-increasing population. Plant-growth-promoting rhizobacteria (PGPR) facilitate the growth and production of vegetable crops by acquiring nutrients, producing phytohormones, and protecting them from various detrimental effects. In this review, we highlight well-developed and cutting-edge findings focusing on the role of a PGPR-based bioinoculant formulation in enhancing vegetable crop production. We also discuss the role of PGPR in promoting vegetable crop growth and resisting the adverse effects arising from various abiotic (drought, salinity, heat, heavy metals) and biotic (fungi, bacteria, nematodes, and insect pests) stresses.
