PEMANFAATAN PLANT GROWTH PROMOTING RHIZOBACTERIA (PGPR) DALAM MENINGKATAKAN POLA PERTUMBUHAN BAWANG MERAH LOKAL (Allium ascalonicum L) SABU RAIJUA NTT

Abstract

Red Onion (Allium ascalonicum L.) Sabu Raijua is one of the horticultural crops that is widely consumed by the people of East Nusa Tenggara (NTT) as a mixture of cooking spices and traditional medicines. For household consumption of around 635,700 tons, non-household consumption such as the manufacturing industry amounting to 719,200 tons, added up to a total of 1.35 million, meaning a deficit for shallots. The purpose of this study was to obtain information about PGPR in increasing the growth pattern of local onion Sabu Raijua. Using Randomized Block Design (RBD) with 5 treatments, namely p0 (control), P1 (5 ml / liter of water / 2 plants), P2 (10 ml / liter of water / 2 plants), P3 (15 ml / liter of water / 2 plants)), P4 (20 ml / liter of water / 2 plants) and repeated 4 times. The results showed that local red onion plants of Sabu Raijua given PGPR could increase plant height (42, 45 cm), number of leaves (57.57 leaflets per plant), number of tillers per plant (13.89 tillers). The higher concentration of PGPR can increase the growth pattern of local onion Sabu Raijua plants.

The Effect of Liquid Organic Fertilizer of Rabbit Urine and Concentration of Plant Growth Promoting Rhizobacteria of Bamboo Root on the Growth and Yield of Mustard Green Plants

“…Should the provision of high PGPR of bamboo root concentrations contain more PGPR bacteria, it can increase the population of microorganisms in the soil and increase the availability of nutrients in the soil and crop production. According to Lehar et al (2018), the function of PGPR in plant growth is as biostimulants, biofertilizers, and bioprotectants. Biostimulants will later produce phytohormones to stimulate growth, biofertilizers to increase crop production by making fertilization efficient, and bioprotectants to protect plants from pathogens (Kasifah, 2022).…”

Pemanfaatan Akar Bambu Sebagai Biang Bakteri Perakaran PGPR Di Desa Latellang

“…PGPR merupakan kelompok bakteri menguntungkan yang agresif dalam melakukan kolonisasi rizofir yang sangat berguna bagi tanaman (Rachma et al, 2018) sebab kemampuanya dalam menyediakan dan memobilisasi atau memfasilitasi penyerapan berbagai unsur hara dalam tanah serta mensistesis serta mengubah konsentrasi fitohormon pemacu tumbuh yang dapat menekan aktivitas pathogen dengan cara menghasilkan senyawa atau metabolit seperti antibiotik dan siderophore (Lehar et al, 2018). Kemampuan PGPR sebagai agen pengendalian hayati karena kemampuannya bersaing untuk memperoleh makanan, bersifat antibiosis, sebagai hormon pertumbuhan tanaman serta ramah lingkungan (Constantia & Ferniah, 2020).…”
