The Effect of Bokashi from Mushroom Baglog Waste and Liquid Organic Fertilizer from Cow Blood Waste on Growth And Production of Shallots (Allium Ascalonicum L.)

Abstract

Shallots are a horticultural commodity that cannot be substituted as a food flavoring. The high demand for shallots due to the increase in population has not been able to meet the demand for shallots optimally in Riau Province. Marginal land in Riau Province and excessive use of chemical fertilizers by farmers have resulted in low soil fertility. One solution is to apply bokashi baglog mushroom waste and liquid organic fertilizer from cow blood waste. The aim of this research was to determine the interaction of Bokashi from Mushroom Baglog Waste and Liquid Organic Fertilizer from Cow Blood Waste on the Growth and Production of Shallots (Allium ascalonicum L.). This study used a Factorial Completely Randomized Design consisting of two factors. The first factor is the dose of bokashi from mushroom baglog waste with four levels: 0, 0.5, 1, and 1.5 kg/plot. The second factor is the liquid organic fertilizer (LOF) from cow blood waste with four levels: 0, 150, 300, and 450 ml/l/plot. The parameters observed included the analysis of bokashi and LOF, plant height, relative growth rate, number of bulbs per clump, wet bulb weight per clump, dry bulb weight per clump, bulb weight loss, bulb diameter, and nutrient absorption analysis (N, P, K) by the plants. The observation data was analysed using analysis of variance and Honestly Significant Difference test at a 5% level. The results showed that the interaction between bokashi from mushroom baglog waste and Liquid Organic Fertilizer from cow blood waste significantly affected relative growth rate, wet bulb weight per clump, dry bulb weight per clump, and bulb weight loss. The best treatment combination was 1.5 kg/plot of bokashi from mushroom baglog waste and 300 ml/l/plot of liquid organic fertilizer from cow blood waste.
