Abstract

The aim of the study was to determine the interaction effect of bokashi fertilizer, swallow droppings and NPK Phonska on the growth and production of peanut plants. The research was carried out at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Jalan Khairudin Nasution KM 11, Air cold Village, Bukit Raya District, Pekanbaru City. The study was carried out for 4 months starting from May to August 2021. The experimental design used in this study was a Completely Randomized Factorial Design (CRD) consisting of two factors. The first factor was the Bokasi swallow manure (W) fertilizer which consisted of 4 levels. While the second factor was Phonska NPK fertilizer which consisted of 4 treatment levels so that 16 treatment combinations were obtained. Each treatment combination had 3 replications so that the experiment consisted of 48 experimental units (plots). In one plot there are 16 plants and 4 of them are used as observation samples which are determined randomly in each plot. So there are 192 sample plants and there are 768 plants. Based on the results of the study it was concluded that the interaction of swallow droppings bokashi and Phonska NPK was significant on plant height, number of root nodules, number of pods per plant, dry seed weight per plant, weight of 100 seeds, weight of wet pods per plant. The best treatment doses are 1.5 kg/plot and 30 g/plot. The main effect of real swiftlet droppings bokashi dosage on all observation parameters. The best treatment dose is 1.5 kg/plot. The main effect of Phonska NPK fertilizer dose was significant on all observation parameters. The best treatment dose is 30 g/plot.
