Efektivitas Aplikasi Mikoriza dan Pupuk Kimia Terhadap Pertumbuhan dan Produksi Tanaman Kacang Panjang (Vigna sinensis L)

Abstract

The thesis was under the guidance of Ir. Suswati, MP as the chief supervisor and Ir. Abdul Rahman, MP as a supervisor. The research aims to determine the effectiveness of mikoriza and chemical fertilizers application to the growth and production of long bean plants. Carried out in the experimental garden of Faculty of the Agriculture University of Medan Area, located at Jalan Kolam No. 1 Medan Estate, Percut Sei Tuan District, from November 2018 to January 2019. The research design used the rancangan acak kelompok (RAK) factorial consisting of 2 treatment factors. Where the factor (1) is mikoriza treatment which consists of 5 levels treatment, i.e A0 = Control (not using mikoriza), A1 = Using mikoriza dose of 100 kg / ha (108 g / plot / 1.08M2), A2 = Using mikoriza dose of 150 kg / ha (16.2 g / plot / 1.08M2), A3 = Using mikoriza dose of 200 kg / ha (21.6 g / plot / 1.08M2), A4 = Using mikoriza dose of 250 kg / ha (27g / plot / 1 , 08M2). Factor (2) application of chemical fertilizers consisting of 4 levels treatment, i.e B0 = Control (not using 0% chemical fertilizer), B1 = Using recommended fertilizer as much as 50% (50 Kg Urea + 75 Kg TSP + 100 kg KCl / Ha), B2 = Using recommendation fertilizer as much as 75% (75 kg Urea + 112.5 kg TSP + 150 kg KCl / Ha) B3 = Using recommendation fertilizer as much as 100% (100 kg Urea + 150 kg + TSP + 200 kg KCl / Ha). This study was conducted as many as 2 replications. The parameters observed in this study are plant height (cm), flowering age (MST), total production per sample, and total production per plot. The results of this study found that chemical fertilizers have a real effect on plant height and no real effect on flowering age, total production per sample and total production per plot.
