EFEKTIFITAS MIKORIZA PADA LIMBAH SAWIT YANG BERBEDA TERHADAP PERTUMBUHAN DAN PRODUKSI BAWANG MERAH (Allium ascalonicum L.)

Abstract

“Introduction: The purpose of this study was to observe the growth and production of shallots against mycorrhiza and a mixture of various palm oil wastes.

Materials and Methods: This research was carried out in the Tunggurono Village, East Binjai District, North Sumatra, from June to September 2022. The research design used was a Factorial Randomized Block Design (RAKF) with 2 factors, where the first factor was mycorrhiza, S0: Control, S1 : 50 gram mycorrhiza, S2 : 100 gram mycorrhiza. The second factor is palm oil waste, T0: Control, T1: Top Soil + Effluent, T2: Top Soil + Fibre, T3: Top Soil + Sludge. Parameters observed were plant height, number of tillers, number of tubers per hill, fresh weight per hill, fresh weight per plot, root volume. stems (mm), flowering age (days), number of fruit planted (fruit), fruit weight planted (g), number of fruit per plot (fruit), fruit weight per plot (g).

Results: The results of the mycorrhizal treatment had a significant effect on wet weight per plot with the best S1 treatment. The treatment of oil palm waste affected the parameters of plant height, number of tillers, wet weight per clump, root volume and had a very significant effect on wet weight per plot, the best treatment was T3 (31.02). The interaction of mycorrhizal treatments and palm waste significantly affected the wet weight per plot and the best treatment was the combination (37.50).
