Response to Mung Bean Growth and Production (Vigna Radiata L.) with Organic Liquid Fertilizer and Biochar Applications

Abstract

The study aimed to determine the effect of biochar and Organic Liquid Fertilizer in various concentrations on the growth and productivity of mung beans (Vigna radiata, L.). The research was conducted on private land located in Watuompak, Mojoagung, Prambon, Nganjuk, East Java with an altitude of 95 meters above sea level, with rainfall in the planting month of 219 mm. This study used a 3 x 4 factorial Complete Random Design (CRD) that repeated 4 times a total of 48 plants. The difference in the concentration of Nasa (P) Organic Liquid Fertilizer with 4 levels, namely: P1 = 100 ml / 1 liter of water; P2= 300 ml/ 1 liter of water;  P3= 500 ml / 1 liter of water. The composition factor of biochar addition media from 3 levels, namely control M0 = control / Soil; M1 = Biochar 50% + Soil = 50%; M2 = Biochar = 25% + Soil = 75%; M3 = Biochar = 10% + Soil = 90%. Observations were made 4 times on 21 Days, 35 Days, 49 Days, and 63 Days. The results showed that composition of media had a single significantly different effect on the number of leaves 63 Days after planting, the best influence was given by the M1 treatment (14.33 leaves). The combination of media treatment and organic liquid fertilizer had a very significant effect on the number of pods 49 Days after planting. Uniform organic liquid fertilizer treatment provided more pod counts than other treatments P3M1(10.75), P2M1(10.5),P2M2(10.25). Variables of plant height, fresh weight, weight of 100 seeds were not found to have a real effect both a combination of treatment and a single treatment carried out.
