Abstract

This study aims to determine the interaction and main effect of detergent waste and paper ash on the growth and production of shallot plants. This research was carried out at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Pekanbaru City, for five to three months from April to June 2022. This study used a Completely Randomized Factorial Design (CRD), which consisted of two factors and 3 replications. The first factor was detergent waste (D) which consisted of 4 levels namely 0%, 50%, 75% and 100% and the second factor was the dose of paper ash which consisted of 4 levels namely 0, 100, 200 and 300 grams per plot. Parameters observed were net assimilation rate, relative growth rate, harvest age, number of tubers per hill, fresh weight of tubers per hill, dry weight of tubers per hill, dry weight of tubers per tuber and tuber losses. The data were analyzed statistically and continued with the BNJ test at the 5% level. The results showed that the interaction effect of detergent waste and paper ash treatment was significant on net assimilation rate, relative growth rate, number of tubers per clump, fresh weight of tubers per clump, dry weight of tubers per clump and tuber losses. The best treatment was the combination without detergent waste and 300 grams of paper ash per plot. The main effect of real detergent waste on all observation parameters, the best treatment without detergent waste administration. The main effect of real paper ash on all observation parameters. The best treatment at a dose of 300 grams per plot.
