Abstract

Lalat pengorok daun (Liriomyza sp.) merupakan salah satu hama penting yang menimbulkan kerugian kualitas pada budidaya krisan. Petani biasa menggunakan pestisida kimia sintetis untuk mengendalikannya. Pestisida nabati sebagai salah satu alternatif pengendalian yang ramah lingkungan dan sesuai dengan pedoman PHT masih belum dilaksanakan. Tujuan penelitian ini untuk mengetahui efektivitas pengendalian pestisida nabati terhadap pengendalian hama pengorok daun (Liriomyza sp), pertumbuhan dan hasil tanaman krisan (Chrysanthemum morifolium Ramat). Penelitian telah dilaksanakan di kubung (rumah plastik) lahan milik petani di Dusun Karang, Desa Gerbosari, Kecamatan Samigaluh, Kabupaten Kulon Progo, DIY. Ketinggian tempat ± 500 m dpl, jenis tanah latosol cokelat, suhu antara 20 - 300 C, kelembaban antara 80 - 90 %, pH tanah 5 - 6. Penelitian dilaksanakan mulai bulan September 2014 sampai dengan Januari 2015.Penelitian lapangan disusun dalam Rancangan Acak Kelompok Lengkap (RAKL) 2 faktor dan 3 ulangan. Faktor pertama adalah konsentrasi pestisida (P) terdiri dari 3 taraf yaitu : Pestisida nabati konsentrasi 0,5 % (P1), Pestisida nabati konsentrasi 1 % (P2), dan Pestisida kimia konsentrasi 0,1 % (P3). Faktor kedua adalah frekuensi pemberian pestisida (F) terdiri dari 2 taraf yaitu: Frekuensi pemberian pestisida seminggu 2 kali (F1), dan Frekuensi pemberian pestisida seminggu 1 kali (F2). Variabel yang diamati dalam penelitian ini adalah tinggi tanaman, jumlah daun, panjang tangkai bunga, diameter bunga, diameter tangkai bunga, bunga dan daun (bekas serangan hama dan penyakit), keadaan tangkai bunga, intensitas serangan Liriomyza sp., keefektifan relatif pengendalian.Hasil penelitian ini menunjukkan tidak terjadi interaksi pengaruh antara macam pestisida dan frekuensi pemberian terhadap semua parameter yang diamati. Keefektivitas Relatif Pengendalian (KRP) pestisida nabati (90,47%) dengan pestisida kimia (85%) berpengaruh sama dalam mengendalikan serangan Liriomyza sp. pada pertumbuhan tanaman krisan. Frekuensi pemberian pestisida nabati dibandingkan kimia berpengaruh sama terhadap semua parameter pertumbuhan, hasil, dan kualitas bunga potong krisan, tetapi menghasilkan lebih tinggi pada diameter tangkai bunga, diameter bunga, dan keadaan tangkai bunga.

Abstract

The aim of this study was to determine the right concentration of rattlepod rhizobacteria and the number of seeds in pods on growth, yield and percentage of seeds in pods of peanut. The experiment was carried out in Sumber Gamol, Balecatur, Gamping, Sleman, Special Region of Yogyakarta. Location of research altitude ± 94 m above sea level (masl), regosol soil type with soil pH 5,6 - 6,0 and temperatures between 24 - 32 oC, rain fall 2000 – 3000 cc year-1. The experiment was arranged by Design Split Plots. The main plots were the concentration of rattlepod rhizobacteria (K), namely 1%, 2% and 3%, the subplots were the number of seeds in pods (P), namely seed pods 1, 2 and 3, each treatment 3 replication. Observation variables included plant height, number of branches, number of leaves, leaf area, leaf fresh weight, number of flowers, number of pods, percentage of pods, percentage of seeds in pods, plant fresh weight, plant dry weight, Relative Growth Rate (RGR) and seed weight per hectare. Data were analysis by analysis of variance followed by Duncan's Multiple Range Test at 5% significance level. Analysis result showed there was no interaction between the combination of rattlepod rhizobacteria concentrations and the number of seeds in the pod on the entire observation variable. The concentration of rattlepod rhizobacteria does not increase the growth and yield of peanuts. The number of seed pods 1 and 2 increases growth but does not increase the yield of peanuts. Seed pods 2 produced the highest percentage of 2 seed pods, while seeded pods 3 produced a significant data result and a lower percentage of 2 seed pods, but 3 seeded pods increased

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh dosis pupuk NPK dan konsentrasi mikrobia rhizosfer terhadap pertumbuhan dan hasil koro pedang. Penelitian ini dilaksanakan pada bulan Januari-Juli 2020 di Desa Wiladeg, Dusun Karangnongko, Kecamatan Karangmojo, Kabupaten Gunungkidul dengan lokasi ketinggian tempat 150-200 m dpl. Jenis tanah adalah grumusol dengan pH tanah 5,0-8,0. Suhu wilayahnya berkisar antara 23-31 oC. Kelembaban nisbi udara berkisar 80-85%. Metode penelitian yang digunakan ialah Rancangan Acak Kelompok Lengkap (RAKL) dengan 2 faktor perlakuan. Faktor I : dosis pupuk NPK (50 kg/ha (N1), 100 kg/ha (N2), 150 kg/ha (N3) dan 200 kg/ha (N4). Faktor II: konsentrasi mikrobia rhizosfer (2% (P1) dan 4% (P2). Data yang diamati pada fase vegetatif adalah jumlah daun, jumlah bintil akar, bobot segar tanaman, dan bobot kering tanaman, sedangkan pada fase generatif adalah jumlah polong per tanaman, bobot polong per tanaman, bobot segar tanaman per hektar, bobot biji per petak dan bobot biji per hektar. Data dianalisis menggunakan sidik ragam, untuk mengetahui pengaruh perlakuan dilanjutkan dengan Duncan’s Multiple Range Test (DMRT) pada taraf α = 5%). Hasil penelitian menunjukkan bahwa dosis NPK dan konsentrasi mikrobia rhizosfer tidak berpengaruh nyata terhadap pertumbuhan koro pedang. Interaksi antara dosis NPK dan konsentari larutan mikrobia rhizosfer terjadi pada variabel bobot polong per tanaman, bobot biji per petak dan bobot biji per hektar. Pemberian NPK dengan dosis 200 kg/ha dan konsentrasi mikrobia rhizosfer 4% meningkatkan bobot polong per tanaman dan menghasilkan bobot biji per hektar tertinggi.
