Abstract

Cogongrass root extract from five different soils types for suppressing purple blotch and increasing growth and yield of shallots. The aim of this study was to examine the efficacy of cogongrass (Imperata cylindrica (L.) Beauv.) root extracts from five different soil types (Typic Udipsamments, Aeric Endoaqualfs (=Gleisal Eutrik), Typic Quartzipsamments (=Regosol Eutrik), Aquertic Chromic Hapludalfs, and Pachic Hapludolls) in suppressing purple blotch and increasing growth and yield of shallots. Split plot design was used with 13 treatments repeated three times, and 18 plants plot-1. The treatments consisted of control, fungicide propineb applied before and after inoculation, and five types of cogongrass root extract 50, 60, and 70% concentration applied before and after inoculation. Results showed that cogongrass root extract collected from Pachic Hapludolls which was applied before inoculation had significant effect on the highest pathosystem component indicated by delaying the incubation period, suppressing the intensity of the disease, slowing down the infection rate, and decreasing values of AUDPC as 41.85, 69.87, 75.13, and 67.63%, respectively, compared to control. The cogongrass root extract from Pachic Hapludolls applied before inoculation could increase plant fresh and dry weight plant-1, tuber weight plant-1, plant fresh and dry weight plot-1, and tuber dry weight plot-1 as 42.7, 49.6, 51.92, 66.75, 72.29, and 73.53%, respectively, compared to control.

Abstract

This study aims to determine the interaction between the effect of liquid organic fertilizer concentration and arbuscular mycorrhizal fungi (CMA) on the growth and yield of red bean plants (Phaseolus vulgaris L.). The experiment was conducted in Nusaherang Village, Nusaherang District, Kuningan Regency, from July to September 2022. The research method used is the experimental method of Group Random Design (RAK) factorial pattern. The treatment consists of two factors and is repeated three times. The first factor is the concentration of liquid organic fertilizer (P), which consists of three levels, namely: P1 (5 ml / l), P2 (10 ml / l), and P3 (15 ml / l). The second factor of arbuscular mycorrhizal fungi (C) consists of three levels, namely: C1 (5 g / plant), C2 (10 g / plant), and C3 (15 g / plant). The primary observation data is processed using variance analysis; if there is a noticeable effect, the test is continued with the Duncan multiple distance test. The results showed a real interaction between the concentration of liquid organic fertilizer and arbuscular mycorrhizal fungi on plant height aged 21 HST, root length aged 21 HST, number of flowers aged 35 HST, and number of pods per red bean plant. The concentration treatment of liquid organic fertilizer has an independent effect on the number of leaves aged 21 HST. In comparison, the treatment of arbuscular mycorrhizal fungi has an independent effect on the number of leaves aged 21 and 28 HST and the number of seeds per pod. The treatment of liquid organic fertilizer and arbuscular mycorrhizal fungi has the same effect on yield variables, so the average weight of fresh red bean beans per plot is 626 g (0.63 kg) or equivalent to 1.6 tons/ha, assuming 80% of the land is effective.

Abstract

Bawang merah saat ini sudah menjadi komoditas yang diperhitungkan di Indonesia, karena keberadaanya menjadi salah satu faktor variabel penentu inflasi secara ekonomi nasional. Kehadiran gulma diantara tanaman bawang merah menjadi kendala dan menyebabkan penurunan produktivitas hasil bawang merah, sehingga perlu dikendalikan secara tepat, efektif dan efisien. Selain itu, bibit merupakan salah satu faktor utama yang menentukan keberhasilan usaha tani bawang merah. Upaya dan strategi harus terus dikembangkan untuk dapat meningkatkan produksi bawang merah, khususnya upaya pengendalian gulma dan penggunaan varietas bibit yang tepat sehingga mampu meningkatkan produktivitas tanaman bawang merah. Tujuan penelitian adalah untuk mengetahui pengaruh bahan aktif herbisida dan varietas terhadap pengendalian gulma, pertumbuhan dan hasil bawang merah. Untuk mengetahui jenis bahan akif herbisida dan  vaietas yang paling tepat untuk pengendalian gulma, pertumbuhan dan hasil bawang merah. Percobaan akan dilaksanakan di Desa Gagasari Kecamatan Gebang Kabupaten Cirebon.pada bulan Februari sampai dengan Mei 2021. Menggunakan Metode Rancangan Acak Kelompok (RAK) pola faktorial dengan 3 kali ulangan. Perlakuan terdiri dari dua faktor yakni faktor pertama adalah bahan aktif herbisida (H0 : Kontrol, H1 : Penyiangan petani, H2 : Oksifluorfen, H3 : Pendimetalin), sedangkan faktor kedua adalah 2 varietas bawang merah (V1 : Varietas Bima, V2 : Varietas Ilokos dan V3 : Varietas Sumenep). Pengamatan utama dilakukan terhadap fitotoksitas dan biomasa gulma, tinggi tanaman, jumlah daun dan bobot kering hasil bawang merah. Hasil penelitian menunjukan bahwa perlakuan herbisida (Oksifluorfen dan Pendimetalin) tidak menimbulkan fitotoksitas atau keracunan bagi tanaman utama bawang merah. Herbisida Oksifluorfen dan varietas sumenep secara mandiri memberikan perbedaan yang nyata terhadap tinggi tanaman pada pengamatan 21, 28 dan 35 HST. Herbisida Oksifluorfen, Pendimetalin dan penyiangan manual serta penggunaan varietas ilokos menunjukan perbedaan yang nyata terhadap jumlah daun. Pengendalian gulma pada tanaman bawang merah dengan menggunakan herbisida lebih efektif dilakukan bila dibandingkan dengan pengendalian penyiangan manual ataupun kontrol. Penggunaan herbisida Oksifluorfen mampu menghasilkan bobot umbi kering bawang merah 5,98 kg/petak atau setara dengan 12,57 ton/hektar. Jenis varietas ilokos mampu menghasilkan bobot umbi kering 5,85 kg per petak atau setara 12,16 ton/hektar.
