Pengaruh Pemberian Pupuk Organik Cair Dan Npk Terhadap Pertumbuhan Dan Produksi Tanaman Kedelai (Glycine Max (L.) Merill)
ABSTRACT
Soybean (Glycine max (L.) Merill) is one of the most important food commodities after rice and corn in Indonesia, so it is widely consumed by the people. The need for this commodity is very high and has only met 34,74% of the needs due to low soybean production and productivity. This study aims to determine the effect of LOF concentration, NPK dose and the best combination for soybean plant growth and production. This research was conducted in the experimental garden of the Faculty of Agriculture, University of Riau. This study used a complete randomized design (CRD) of 2 factors and 3 repeats. The first factor consists of 4 levels, namely LOF concentration (0, 2, 4, and 6 ml.l-1). The second factor consists of 4 levels, namely NPK dose (100, 200, and 300 kg.ha-1). The results showed that giving LOF Super Bionic concentration of 6 ml.l-1 water markedly increased the number of productive branches, number of pods per plant, weight of seeds per plant, weight of seeds per m2 and weight of 100 seeds of plants. The administration of NPK dose 300 kg.ha-1 markedly increased the number of pods per plant, seed weight per plant and seed weight per m2. The combination of LOF Super Bionic 6 ml.l-1 water and NPK fertilizer 300 kg.ha-1 provides the best results to increase the growth and production of Grobogan variety soybean plants so that the highest yield of 320,14 g.m-2 (3,2014 t.ha-1) is obtained. Based on the results of research that has been carried out, to get good growth and production of soybean plants, it is recommended to use LOF Super Bionic 6 ml.l-1 water and NPK fertilizer 300 kg.ha-1.
