PENGARUH KOMBINASI PUPUK KOMPOS BIOMASA KIRINYU DAN PUPUK NPK AN ORGANIK TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN BAWANG MERAH (Allium ascalonicum L.)

Abstrak

The research was conducted from April to July 2021, in Baru Village, Reok District, Manggarai Regency, which aimed to determine the effect of a combination of kirinyu biomass fertilizer and NPK Mutiara fertilizer on the growth and production of shallot plants (Allium ascalonicum L.). The study was designed using a randomized block design, with 9 combination treatments, repeated in 3 blocks, so there were 27 experimental plot units. The treatment tested was a combination of kirinyu biomass fertilizer doses and NPK Mutiara fertilizer doses. The variables observed were plant height, the increase in the number of leaves, the number of bulbs per hill, the weight of shallot bulbs per hill and per plot. Observational data were analyzed by means of variance and continued with Duncan's test at the 5% level.. The results of this study indicate that: 1). The combination treatment of kirinyu biomass compost and Mutiara NPK fertilizer had a significant effect on the variables of plant height increase and number of leaves at the age of 20 - 35 HST, number of tubers, dry weight of shallot bulbs per plant, and tuber dry weight per plot. 2). The combination treatment of kirinyu biomass compost and Mutiara NPK in the application of kirinyu biomass fertilizer 20 tons/ha and the dose of NPK Mutiara 100 kg/ha (P5) increased the best growth and production of shallots, with the achievement of dry weight of shallot bulbs per plot of 1, 47 kg or the equivalent of 14,7 tonnes/ha.
