Tujuan penelitian ini adalah untuk mengetahui respon pertumbuhan dan hasil tanaman jagung manis menggunakan biopestisida berbasis B. subtilis B1 di lapangan serta membandingkannya dengan bakterisida. Penelitian dilaksanakan di lahan desa Kebanggan, Kecamatan Sumbang. Penelitian dilaksanakan selama 4 bulan, mulai bulan Maret sampai Juni 2018. Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) yang terdiri atas 3 perlakuan (B. subtilis 50 ml/tanaman, bakterisida 50 ml/tanaman dan kontrol) dan 9 kali ulangan. Variabel pengamatan meliputi tinggi tanaman (cm), jumlah daun (helai), diameter batang (g), bobot akar segar (g), bobot akar kering (g), bobot tanaman segar (g), bobot tanaman kering (g), luas daun (cm2), bobot tongkol (g), panjang tongkol (cm), dan diameter tongkol (cm). Hasil penelitian menunjukkan bahwa pemberian Biopestisida berbasis Bacillus subtilis B1 menunjukkan pengaruh tidak berbeda nyata terhadap pertumbuhan dan hasil tanaman jagung manis. Variabel bobot tajuk segar, bobot tajuk kering, bobot akar segar dan bobot akar kering perlakuan yang diberikan tidak berpengaruh nyata. Pemberian Bacillus subtilis dengan pemberian bakterisida menunjukan bobot tajuk segar dengan nilai berturut-turut yaitu 274,4 g dan 260,44 g. Tanaman yang diberi Bacillus subtilis menunjukkan bobot tongkol berkelobot, yang tidak berbeda dengan bakterisida yaitu berurut-urut 300,5 g dan 297,4 g.

The purpose of this study was to determine the growth response and yield of sweet corn plants using B. subtilis B1 based biopesticides in the field and compare them with bactericides. The research was carried out in the village of Kebanggan, Kecamatan Sumbang. The study was conducted for 4 months, from March to June 2018. The experimental design used was a randomized block design (RBD) consisting of 3 treatments (B. subtilis 50 ml/plant, bactericidal 50 ml/plant and control) and 9 replications. Observation variables included plant height (cm), number of leaves (strands), stem diameter (g), fresh root weight (g), dry root weight (g), fresh plant weight (g), dry plant weight (g), area leaf (cm2), ear weight (g), ear length (cm), and ear diameter (cm). The results showed that the administration of Biopesticides based on Bacillus subtilis B1 showed no significant effect on the growth and yield of sweet corn plants. Variables of fresh canopy weight, dry canopy weight, fresh root weight and dry root weight were not significantly affected. Giving Bacillus subtilis with bactericidal administration showed fresh canopy weights with values of 274.4 g and 260.44 g, respectively. Plants that were given Bacillus subtilis showed weighted cob weight, which was not different from bactericidal namely 300.5 g and 297.4 g.
