Penelitian ini bertujuan untuk 1) mengetahui pengaruh pemberian Pseudomonas fluorences terhadap pertumbuhan dan hasil tanaman padi gogo, 2) mengetahui pengaruh pemberian silika organik dengan berbagai ukuran partikel terhadap pertumbuhan dan hasil tanaman padi gogo, 3) mengetahui interaksi antara silika organik dan Pseudomonas fluorences terhadap pertumbuhan dan hasil tanaman padi gogo. Penelitian dilaksanakan pada bulan Juli 2018 sampai November 2018 di Desa Kalibagor, Kecamatan Kalibagor, Kabupaten Banyumas. Rancangan yang digunakan adalah rancangan acak kelompok (RAK) dengan dua faktor perlakuan dan tiga kali ulangan. Faktor pertama adalah ukuran pupuk silika organik yang terdiri dari empat ukuran yaitu 2, 1,5, 1, 0,5 mm dan tanpa pemberian silika organik. Faktor kedua adalah Pseudomonas fluorences yang terdiri atas pemberian Pseudomonas fluorences dan tanpa pemberian Pseudomonas fluorences. Variabel yang diamati yaitu panjang akar total, tinggi tanaman, luas daun, kehijauan daun, jumlah anakan, bobot kering tanaman, jumlah anakan produktif, panjang malai, jumlah gabah isi per malai, jumlah gabah hampa per malai, jumlah gabah isi per rumpun, jumlah gabah hampa per rumpun, jumlah gabah per rumpun, bobot gabah isi per rumpun, bobot gabah hampa per rumpun, bobot gabah per rumpun, bobot 1000 biji, dan indeks panen. Hasil penelitian menunjukkan bahwa Pseudomonas fluorences meningkatkan panjang malai, jumlah anakan produktif, jumlah gabah isi per rumpun. Pemberian silika organik dengan berbagai ukuran partikel belum mampu meningkatkan pertumbuhan dan hasil tanaman padi gogo. Tidak ada interaksi antara silika organik dan Pseudomonas fluorences dalam meningkatkan pertumbuhan dan hasil tanaman padi gogo.
Kata kunci: silika organik, Pseudomonas fluorences, ukuran partikel silika organik, padi gogo.

The aims of the research were 1) to study the effect of organic silica with various sizes on the growth and yield of upland rice, 2) to study the effect of Pseudomonas fluorences on the growth and yield of upland rice,3) to study the interaction effect of organic silica and Pseudomonas fluorences on the growth and yield of upland rice. The research was conducted from July until November 2018 at the Kalibagor Village, Kalibagor Subdistrict, Banyumas Regency. The research was arranged by randomized completely block design (RCBD) with two factors and repeated in three times. The first factor was the size of silica organik i.e. 2, 1.5, 1, 0.5 mm and control without organic silica application. The second factor was the Pseudomonas fluorences application and without Pseudomonas fluorences application. The observed variables were root length, plant growth rate, leaf area, green leaves, the number of tiller, dry biomass, the number of productive tiller, panicle length, the number of filled seeds grains per clum , the number of filled seeds grains per panicle, the number of unfilled seeds grains per clum, the number of unfilled seeds grains per panicle, the number of seeds grains per clum, filled seeds grains weight per clump, unfilled seeds grains weight per clump, seed grains weight per clump, 1000 seeds grains weight, harvest index. The results showed that Pseudomonas fluorences increase the number of productive tiller, panicle length, the number of filled seed grains per clump. Application of the size of the organic silica does not affect to the on the growth and yield of upland rice. There was no interaction between organic silica and Pseudomonas fluorences in increase growth and yield of upland rice.
Keyword: organik silica, Pseudomonas fluorences, size of organic silica, upland rice.
