Abstract

Rizobakteria pemacu pertumbuhan tanaman merupakan kelompok bakteri yang aktif mengkolonisasi prakaran tanaman dan meningkatkan pertumbuhan, hasil tanaman serta mampu mengendalikan pathogen. Penelitian ini bertujuan untuk memperoleh isolat rizobakteria yang mampu mengendalikan penyakit layu bakteri dan meningkatkan pertumbuhan dan hasil kentang. Metode penelitian berdasarkan pada penapisan secara in planta rizobakteria dari tanah perakaran tanaman kentang yang sehat dari daerah endemik penyakit layu bakteri di Kab. Solok, Sumatera Barat. Isolat bakteri rizobakteria yang dikarakterisasi yang mampu menekan penyakit latu bakteri dan meningkatkan pertumbuhan serta hasil umbi. Pemakaian teknik ini memungkinkan untuk menemukan agens hayati yang baru, lebih mudah dan murah. sepuluh isolat bakteri rizobakteri diintroduksi pada benih kentang (108 cfu/ml). Peubah yang diamati adalah insidensi dan severitas penyakit layu bakteri, pertumbuhan dan hasil pada umbi kentang. Hasil penelitian menunjukkan bahwa 2 isolat bakteri rizobakteri dari perakaran kentang (BT12Rz2.1 dan TD4Rz1.1) merupakan isolat terbaik dalam meningkatkan pertumbuhan dan hasil umbi kentang dengan efektivitas 20,62% dan 20,47%.

Abstract

Nagari Sungai Durian of Solok District is one of the village that has various problems suchas drought, high number of unused land and the distance of urban access. In the cultivation of foodcrops required a lot of water such as rice, so that productivity is not optimal. For that the selection ofcorn as a cultivation plant is a possible thing because corn plants merupkan food crops that do notrequire much water. But some of the constraints faced when corn plant perspectives are low productivitydue to disruption of pests and diseases and soil less fertile. The solution that can be offered is by plantingcorn crops that are more resistant to drought and the use of rhizobacteria as pest and disease controlagents. In addition to pest and disease control agents, the use of rhizobacteria which also called PGPR(Plant Growth Promoting Rhizobacteria) that can increase growth and yield of plants. The purpose ofthis community service program is to provide knowledge to the community in the cultivation of corncrops with the application of rhizobacteria. This activity is done by socialization and demonstrationplot. This activity has been able to educate the general community about farmers about corn cultivationwith rhizobakteri application. From this activity also can be concluded that corn plant with applicationof Rhizobakteri have growth and yield higher than corn plant without application of Rhizobakteri.

One of the ways to do this is by taking preventive action by providing immunity induction from the seedling stage. Immunity induction can be done by utilizing Rhizobacteria, arbuscular mycorrhizal fungi, Entomopathogenic fungi, and vegetable pesticides. The Faculty of Agriculture of Universitas Andalas collaborated with the entrepreneurs through a Ministry of Education and Culture program, Matching Fund 2022, to make an innovation, namely the Teaching Farm for superior cocoa nurseries. This activity aims to socialize the cocoa nursery teaching farm in the hope of helping farmers prepare high-quality and sustainable cocoa seeds.
