Abstract

Penelitian bertujuan untuk mengetahui penyakit penting tanaman padi dan penyebab nya, serta jamur-jamur endofit pada tanaman padi dan potensinya sebagai agens pengendali hayati. Lokasi pengambilan sampel di Kelurahan Lempake Kecamatan Samarinda Utara Kota Samarinda. Penelitian ini dilaksanakan di Laboratorium Ilmu Hama Penyakit Tumbuhan Fakultas Pertanian Universitas Mulawarman. Kegiatan dilaboratorium meliputi isolasi, identifikasi dan uji daya antagonis menggunakan tanaman padi sehat untuk memperoleh jamur endofit dan tanaman padi sakit yang menimbulkan gejala untuk memperoleh cendawan patogen. Metode yang digunakan adalah dengan menggunakan Rancangan Acak Lengkap (RAL).Hasil penelitian menunjukkan bahwa jamur endofit yang terisolasi pada tanaman padi dari lokasi penelitian di Kelurahan Lempake, Kecamatan Samarinda Utara terdapat 3 jenis yaitu: Trichoderma sp., Aspergillus niger dan Mucor sp., sedangkan jamur patogen yang ditemukan menyerang tanaman padi yaitu Cercospora sp. dan Rhizoctonia Solani. Berdasarkan hasil uji antagonis secara in-vitro bahwa ketiga jamur endofit terhadap dua cendawan patogen memiliki besaran hambatan rata-rata diatas 50% tingkat tertinggi penghambatan yaitu Trichoderma sp. vs Rhizoctonia dengan daya hambatan (89,20%).

Abstract

The purpose of this study was to find the best dosage of Trichokompos fertilizer which gives the best results on shallot plants and to determine the amount or frequency of weed control that affects shallot plants. Kutai Kartanegara Regency, East Kalimantan Province , since November 2019 until January 2020. The research used the Split Plot design 4x5 consisting of 2 factors and repeated 3 times. The First factor is Trichocompos fertilizer (t) consisting of 4 levels, namely (t0) No Fertilization, (t1) 2,5 kg plot-1, (t2) 3 kg plot-1, (t3) 3,5 kg plot-1. The second factor is weed control (g) consisting of 5 levels, namely (g0) without weed control, (g1) once a week equivalent to 8 times weed control, (g2) once a week equivalent to 4 times weed control, (g3) once a week equivalent to 3 times weed control, (g4) once a week equivalent to 2 times weed control. The results showed the effects of weed control on the number of leaves at the age of 40 and 60 dap, the number of tubers showed a significant effect. Plants that are free from weeds will show better growth when compared to those grown with 6.69 tubers of weeds. Then the lowest average result is the treatment of 5.36. Weed control also had a significant effect on weed populations and weed dry weight. It is suspected that there are weed seeds that are buried in the soil during the soil cultivation process causing the seeds to be lifted back to the surface of the soil during weed removal which causes new weeds to grow.
