Abstract

Testing the macro nutrient value of chicken manure decomposed by Trichoderma viride. This study aims to determine the value of macro nutrients in chicken manure decomposed by Trichoderma viride. This research was carried out on the field of the Faculty of Agriculture, Graha Nusantara Padangsidimpuan University, from February to August 2018. The results showed that compost with the addition of decomposer Trichoderma viride which was good was 4 weeks (A4), namely organic B = 45.70%, organic C = 91.03, C / N ratio = 11, 13%, total N = 3.51%, total P = 3.41%, total K = 1.58%

Abstract

Pengaruh kombinasi berbagai pupuk organic yang didekomposisi dengan Trichoderma viride terhadap intensitas kerusakan bonggol tanaman pisang. Penelitian ini bertujuan untuk mengetahui kombinasi jenis bahan organik dalam menekan intensitas kerusakan bonggol tanaman pisang terhadap Fusarium oxysporum Schl. f. sp. cubense (Foc). Penelitian ini dilaksanakan di lahan Fakultas Pertanian, Universitas Graha Nusantara Padangsidimpuan, mulai Februari sampai bulan Agustus 2019. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) yang terdiri atas 5 perlakuan dan 4 ulangan. Perlakuan adalah kombinasi berbagai bahan organik sebagai berikut : (a) Kotoran ayam dan jerami didekomposisi oleh T. viride, (b) Kotoran sapi dan jerami didekomposisi oleh T. viride, (c) Kotoran ayam dan kotoran sapi didekomposisi oleh T. viride, (d) Kotoran sapi, kotoran ayam dan jerami didekomposisi oleh T. viride, (e) Kontrol. Hasil penelitian menunjukkan intensitas kerusakan bonggol terendah yaitu pada perlakuan SAJ (menggunakan bahan organic kotoran sapi, kotoran ayam dan jerami) sebesar 0,42 %.

Abstract

Effect of immersion duration of trichoderma harzianum on local chili growth the aim of this researchis to see the old soaking ability of Trichoderma harzianum mushroom on the growth of local chili.The design used was a Completely Randomized Design (CRD) consisting of 6 treatments and 4replications, namely local chili seeds soaked with a 5-minute T.harzianum suspension, local chiliseeds soaked with a 10-minute T.harzianum suspension, local chili seeds that were soaked marinatedwith T.harzianum suspension for 15 minutes, local chili seeds soaked with T.harzianum suspensionfor 20 minutes, local chili seeds soaked with T.harzianum suspension for 25 minutes, Control (withoutimmersion with trichoderma harzianum suspension. Observed parameters are the percentage of local chiligrowth, plant height and number of leaves The results showed that the application of trichoderma harzianumhad a good effect on the growth of chili plants, soaking for 25 minutes was the best soaking on localchili seeds.
