Uji efektifitas Inokulasi Rhizobium Dan POC Limbah Ikan Terhadap Pertumbuhan Dan Produksi Kacang Tanah

Abstract

This research was conducted in the Experimental Garden, Faculty of Agriculture, University of Medan, JalanJalan No. 1 Medan Estate PercutSei Tuan Subdistrict with a height of 12 meters above sea level (asl), flat topography, Alluvial soil type and soil pH 7. This research was conducted in October to January 2019. This research used a factorial (RBD) that consists of 2 treatment factors, namely: 1) Factor of Rhizbium Inoculation (R notation) consisting of 3 levels of treatment, namely: R0 = control (not using rhizobium inoculation); R1 = Rhizobium inoculation ie 10 grams / kg of seed; R2 = Rhizobium inoculation ie 15 grams / kg of seed; whereas for the second treatment) Provision of liquid organic fertilizer (POC) Fish Waste (L notation) consisting of 4 levels of treatment, namely: L0 = control (not using POC Fish Waste); L1 = using POC Fish Waste concentration 25% (250 ml / l); L2 = using POC Waste fish concentration of 50% (500 ml / l); L3 = using POC Fish Waste concentration of 75% (750 ml / l). The parameters observed in this study were plant height, number of branches, flowering age, volume of root nodules, number of pods per sample, total weight of 100 seeds, production weight per sample and production weight per plot. The results showed that: 1) The administration of Rhizobium inoculation significantly affected the parameters of plant height, number of branches, weight of 100 seeds but did not show any significant difference to the parameters of flowering age, root nodules volume and number of sample planted pods. Rhizobium inoculation treatment with a dose of 15 gr / kg of seed showed the best growth and production 2) besides that the treatment of liquid organic fertilizer of fish waste did not significantly affect all observed parameters and 3) while the combination of rhizobium inoculation and POC of fish waste showed no significant effect on the growth and production of peanuts.
