UJI DOSIS PUPUK K DAN BERBAGAI MEDIA TANAM TERHADAP PERTUMBUHAN DAN HASIL BAWANG MERAH VARIETAS BIMA (Allium ascalonicum L.)

Abstract

This study aims to determine the effect of K2O Fertilizer Dosage and Various Planting Media on Growth, Yield and Interaction of the Two Treatments on Shallots (Allium ascalonicum L.). This research was conducted in August 2020 in Jembungan Village, Banyudono District, Boyolali Regency with an altitude of ± 195 meters above sea level with entisol soil type.
 This study used a factorial method with a completely randomized design (CRD) consisting of two factors with three replications. The first factor is the dose of K2O (K) fertilizer, consisting of 3 levels: K1 = 100 kg/ha, K2 = 200 kg/ha, K3 = 300 kg/ha. The second factor is Planting Media (M), consisting of 4 levels: M1 = Soil Planting Media + Bokashi, M2 = Soil Planting Media + Cow Manure, M3 = Soil Planting Media + Goat Manure, M4 = Soil Planting Media + Cocopad.
 The results of the study can be concluded as follows: 1) The dose of K2O (K) fertilizer has a very significant effect on all growth parameters and yield parameters, 2) Planting Media has a significant effect on plant height and fresh stover, no significant effect on the number of leaves, dry stover and all result parameters. 3) The combination of the treatment dose of K2O fertilizer and Planting Media (K x M) showed a very significant effect on all growth parameters and yields of shallots.
