Pengaruh Kombinasi Berbagai Jenis Pupuk Organik yang Didekomposisi dengan Trichoderma Viride Terhadap Intensitas Kerusakan Bonggol Tanaman Pisang

Abstract

Pengaruh kombinasi berbagai jenis pupuk organik yang didekomposisi dengan trichoderma viride terhadap intensitas kerusakan bonggol tanaman pisangThe effect of various combination types of organic fertilizers in decomposition with trichoderma viride on intensity of damage plants of banana plants ABSTRACTEffect of a combination of various organic fertilizers decomposed with Trichoderma viride on the intensity of damage to banana weevil. This study aims to determine the combination of types of organic matter in suppressing the intensity of damage to banana weevil on Fusarium oxysporum Schl. f. sp. cubense (Foc). This research was carried out on the grounds of the Faculty of Agriculture, Graha Nusantara University, Padangsidimpuan, from February to August 2019. This study used a randomized block design (RBD) consisting of 5 treatments and 4 replications. The treatment is a combination of various organic ingredients as follows: (a) Chicken manure and straw are decomposed by T. viride, (b) Cow manure and straw are decomposed by T. viride, (c) Chicken manure and cow manure are decomposed by T. viride, (d) Cow manure, chicken manure and straw decomposed by T. viride, (e) Control. The results showed the lowest intensity of weevil damage was in the SAJ treatment (using organic matter cow dung, chicken manure and straw) of 0.42%. ABSTRAKPengaruh 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 %.

“…This is in line with the opinion of Singh et al (2014) that elements such as carbon and nitrogen play an important role in the cellular balance of Trichoderma sp. Wahyuni & Nst, (2019) also stated that microorganisms use carbon for growth and energy, while nitrogen is used for protein and reproduction .…”
