Pengaruh Pupuk NPK Dan Mikroorganisme Lokal Kulit Nenas Terhadap Produksi Tanaman Kacang Tanah (Arachis hypogaea L.)

Abstract

To study the effect of NPK fertilizer dosage and pineapple peel IMO concentration and their interactions on the yield of peanut (Arachis hypogaea L.), a research was carried out from April to July 2023 on Ultisol in Medan, Indonesia. The study used a Factorial Randomized Block Design consisting of two factors and three replications.  The factors were NPK fertilizer dosage {N0 = 0 kg/hectare, N1 = 125 kg/hectare, N2 = 250 kg/hectare, and N3 = 375 kg/hectare}, and pineapple peel IMO concentration (M0 = 0 ml/liter, M1 = 20 ml/liter, M2 = 40 ml/liter, and M3 = 60 ml/liter). The parameters observed were: pod production per plot, weight of 100 dry seeds, seed production per plot and yield per hectare.  The results showed that the dosage of NPK fertilizer had a very significant effect on pod production per plot, weight of 100 seeds, seed production per plot and yield per hectare, while the concentration of pineapple peel MOL had a very significant effect on pod production per plot, seed production per plot and yield per hectare, but had no significant effect on weight of 100 dry seeds. The optimum dosage of NPK fertilizer dose was 163,25 kg/ha. The optimum concentration of pineapple peel IMO was 32,10 ml/liter. The interaction between NPK fertilizer dosage and pineapple peel IMO concentration had no significant effect on all research parameters.
