Pertumbuhan dan Produksi Tanaman Kacang Kedelai (Glycine max (L.) Merril) dengan Pemberian Pupuk Petroganik dan NPK
Soybean (Glycine max (L.) Merrill) is one of the food crop commodities that play an important role in meeting national food needs, soybeans are one of the sources of vegetable protein that is quite affordable, when compared to other protein sources. This research aims to study the interaction effect and main factors of Petroganic and NPK fertilizers and to find the best combination of Petroganic and NPK fertilizers on the growth and production of soybean plants. The research was conducted experimentally using a completely randomized design (CRD) factorial
consisting of two factors. The first factor is Petroganic fertilizer which consists of four levels, namely: Petroganik 0 t.ha-1, Petroganik 5 t.ha-1, Petroganik 6 t.ha-1, Petroganik 7 t.ha-1. The second factor is NPK fertilizer consisting of four levels, namely: NPK 0 kg.ha-1, NPK 150 kg.ha-1, NPK 200 kg.ha-1, NPK 250 kg.ha-1. The results obtained using analysis of variance and Duncan's multiple further tests using software, namely Statistical Analysis System (SAS) at the 5% level. The application of Petroganik 6 t.ha-1 and NPK 200 kg.ha-1 fertilizers can increase the growth and production of soybean plants.
