Aplikasi Pupuk Granular Organik Berbahan Limbah Sawit dan Rhizobium terhadap Pertumbuhan dan Hasil Kacang Tanah

Abstract

Peanuts are the most important agricultural commodities after soybeans which have a strategic role in national food as a source of protein and vegetable oil, so that it has the potential to be developed because it has good economic value and has a large domestic market opportunity. This study aims to obtain information on the application of organic granular fertilizers and rhizobium and their interactions with the growth and yield of peanuts. The research was carried out at the experimental land of the Faculty of Agriculture at the University of Ratu Samban Arga Makmur Bengkulu Utara from June to September 2018. The research method used a two-factor randomized block design with 3 replications. The first factor was the treatment of organic granular fertilizer with six levels, control (G0), organic granular fertilizer 25 g plant-1 (G1), organic granular fertilizer 50 g plant-1 (G2), organic granular fertilizer 100 g plant-1 (G3), organic granular fertilizer 150 g plant-1 (G4), organic granular fertilizer 200 g plant-1 (G5). The second factor is the treatment of Rhizobium, consisting of two levels, namely control (R0) and rhizobium (R1). The results showed that the treatment of organic granular fertilizer had a significant effect on seed weight per plant and treatments of 100 g plant-1 and 150 g plant-1 produced the highest seed weight of tan-1 9.38 g and 9.32 g, respectively. Rhizobium treatment significantly affected plant height and number of branches 7 week after planting. Rhizobium treatment produced the highest plant height of 36.11 cm and more branches of 5.56 stems. There is no interaction between granular organic fertilizer and rhizobium.
