Abstract

Permasalahan budidaya kacang hijau di Indonesia adalah produktivitas yang masih rendah dan lahan budidaya yang terbatas, sehingga dapat diatasi dengan mengoptimalkan lahan marginal seperti tanah ultisol untuk kegiatan budidaya kacang hijau. Tujuan pene-litian ini adalah untuk mengetahui varietas kacang hijau dan jenis pupuk organik yang mampu menghasilkan produksi tinggi di tanah ultisol. Penelitian dilakukan menggunakan polibag di Screen House, Fakultas Pertanian, Universitas Jenderal Soedirman pada bulan Juli-September 2015. Penelitian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan dua faktor. Faktor pertama adalah varietas kacang hijau yang terdiri atas tiga varietas, yaitu Vima 1, Betet, dan Murai. Faktor kedua adalah jenis pupuk, yaitu tanpa pupuk (kontrol), pupuk kandang ayam, pupuk bokashi rumen sapi, dan pupuk bokashi limbah sayuran pasar. Variable yang diamati antara lain jumlah cabang per tanaman, jumlah polong isi per tanaman, bobot biji per tanaman, bobot 100 biji, dan indeks panen. Hasil penelitian menun-jukkan bahwa pupuk organik kandang ayam dan pupuk bokhasi rumen sapi mampu meningkatkan hasil kacang hijau. Kata kunci: Kacang hijau ∙ Pupuk organik ∙ Ultisol

Abstract

Weeds are managed by herbicides, but this can reduce the abundance of soil bacteria. This research aimed to determine the effect of active compounds of herbicides on weeds, the abundance of soil bacteria, growth and yield of sweet corn. The experiment was conducted from June to October 2023 in the fields and Laboratory of Agronomy and Horticulture, Universitas Jenderal Soedirman, Purwokerto. A randomized block design was used, consisting of eight treatments and four replications. The treatments included control (H0); weeding (H1); paraquat (H2); glyphosate (H3); paraquat, atrazine, mesotrione (H4); glyphosate, atrazine, mesotrione (H5); paraquat, atrazine, mesotrione, nicosulfuron (H6); and glyphosate, atrazine, mesotrione, nicosulfuron (H7). Results showed that glyphosate and paraquat, were applied before planting, could suppress weeds on sweet corn until 15 days after planting (DAP). Application of atrazine, mesotrione, and nicosulfuron at 21 DAP can increase the success of weed control observed up to 35 DAP of sweet corn. The application of glyphosate, atrazine, and mesotrione showed the highest values for growth variables (plant height, number, and leaf greenness index) and yield variables (fresh weight, diameter, and length of sweet corn cob). Herbicide decrease abundance of soil bacteria on sweet corn field, from 10.07x10-8 CFU/mL to 9.55x10-8 CFU/mL (total bacteria), 9.53x10-8 CFU/mL to 9.52x10-8 CFU/mL (phosphate solubilizing bacteria), 9.90x10-8 CFU/mL to 9.40x10-8 CFU/mL (Rhizobium) and 9.91x10-8 CFU/mL became 9.78x10-8 CFU/mL (nitrogen fixing bacteria). The total density of phosphate-solubilizing bacteria and nitrogen-fixing bacteria in the application of glyphosate, atrazine, and mesotrione (7.78 CFU/g and 9.52 CFU/g) was greater than control (8.77 CFU/g and 8.15 CFU/g).
