Abstrak. penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi pupuk organik cair bonggol pisang dan varietas serta untuk mengetahui interaksi antara kedua faktor tersebut terhadap pertumbuhan dan hasil tanaman tomat. penelitian ini telah dilaksanakan di kampung sioldengan, kecamatan rantau selatan, kabupaten labuhan batu, provinsi sumatra utara. penelitian ini menggunakan rancangan acak kelompok pola faktorial 4x3 dengan 3 ulangan. faktor yang diteliti yaitu pengaruh konsentrasi pupuk organik cair bonggol pisang yang terdiri dari 4 taraf yaitu kontrol, 15, 30 dan 45 ml l-1 air dan varietas yang terdiri dari 3 taraf yaitu servo f1, tymoti dan permata. hasil penelitian menunjukkan bahwa konsentrasi pupuk organik cair bonggol pisang berpengaruh tidak nyata terhadap semua parameter yang diamati. pertumbuhan dan hasil tanaman tomat cenderung lebih baik dijumpai pada konsentrasi pupuk organik cair bonggol pisang 45 ml l-1 air. perlakuan varietas tanaman tomat berpengaruh sangat nyata terhadap tinggi tanaman dan diameter batang tomat umur 15, 30 dan 45 hst, berpengaruh nyata terhadap jumlah buah per tanaman dan bobot buah per tanaman serta berpengaruh tidak nyata terhadap umur berbunga, bobot buah per buah. pertumbuhan dan hasil tanaman tomat terbaik dijumpai pada tanaman tomat varietas tymoti. terdapat interaksi yang sangat nyata antara konsentrasi pupuk organik cair bonggol pisang dan varietas terhadap tinggi tanaman tomat umur 30 hst. pertumbuhan tanaman tomat lebih baik dijumpai pada kombinasi pupuk organik cair bonggol pisang kontrol dengan varietas tymoti. kata kunci : pupuk organik cair, bonggol pisang, varietas

Abstract. This study aims to determine the effect of the concentration of banana weevil liquid organic fertilizer and varieties and to determine the interaction between the two factors on the growth and yield of tomato plants. This research was carried out in Kampung Sioldengan, South Rantau District, Labuhan Batu Regency, North Sumatra Province. This study used a 4x3 factorial randomized block design with 3 replications. The factors studied were the effect of the concentration of banana weevil liquid organic fertilizer consisting of 4 levels namely control, 15, 30 and 45 ml L-1 of water and varieties consisting of 3 levels namely Servo F1, Tymoti and Permata. The results showed that the concentration of banana weevil liquid organic fertilizer had no significant effect on all observed parameters. Growth and yield of tomato plants tended to be better found at the concentration of banana weevil liquid organic fertilizer 45 ml L-1 water. The treatment of tomato plant varieties had a very significant effect on plant height and stem diameter of tomatoes aged 15, 30 and 45 HST, had a significant effect on the number of fruits planted and fruit weight planted and had no significant effect on flowering time and fruit weight per fruit. The best growth and yield of tomato plants were found in tomato plants of the Tymoti variety. There was a very significant interaction between the concentration of banana weevil liquid organic fertilizer and variety on the height of tomato plants aged 30 HST. Better growth of tomato plants was found in the combination of control banana weevil liquid organic fertilizer and the Tymoti variety. Better growth of tomato plants was found in the combination of controlling banana weevil liquid organic fertilizer with the Tymoti variety. Key words : Organic liquid fertilizer, banana weevil and variety
