Pengaruh Pupuk Organik Cair dan Hormon Giberelin Terhadap Pertumbuhan dan Produksi Benih Kacang Hijau (Vigna radiata L.)

Abstract

One of the efforts to increase the growth and production of mung bean seeds can be done by applying NASA POC and GA3 hormones. This research was conducted to determine the effect of giving NASA Liquid Organic Fertilizer (POC) and giving the hormone Gibberellin (GA3) to increasing growth and seed production of mung bean (Vigna radiata L.). This trial was carried out in August-November 2022, at the Jember State Polytechnic agricultural land. The experimental design used in this study was a factorial Randomized Completed Block Design (RBD) consisting of two factors and repeated 3 times. The first factor was the NASA POC concentration (P), consisting of 5 ml/l (P1), 10 ml/l (P2), and 15 ml/l (P3). The second factor was the concentration of Gibberellins (G), consisting of 125 ppm (G1), 150 ppm (G2), and 175 ppm (G3). The results obtained were then analyzed using the F test or ANOVA (Analysis of Variance) and then the DMRT test was carried out. The treatment of the NASA POC application had a very significant effect (**) on the parameter number of productive branches. The best result was the P3 treatment (2.93 branches). The treatment with the hormone GA3 (Giberelin) had a very significant effect (**) on the parameters of plant height at 28 hst the best result was the G2 treatment (26.37 cm) and had a significant effect (*) on the parameters of plant height at 14 hst with the best treatment results G2 (12.72cm). The interaction between the application of NASA POC and the GA3 hormone had a significant effect (*) on the parameters of the amount of production per hectare with the best treatment interaction, namely P3G2 (738.35 kg)
