Abstract

The study entitled "The Effect of Rabbit Urine and KCl Fertilizer on the Growth and Production of Sweet Potato Plants (Ipomoea batatas L.)", aims to determine the interaction and main effect of rabbit urine and KCl fertilizer on the growth and production of sweet potato plants. This research was carried out at UIRA Farm Agro, Faculty of Agriculture, Islamic University of Riau. This research lasted for four months from November 2021 to February 2022. The experimental design used was a Completely Randomized Factorial Design which consisted of 2 factors. The first factor was the concentration of rabbit urine with 4 treatment levels, namely 0, 20, 40, 60 ml per l of water, and the second factor was the dosage of KCl fertilizer with 4 treatment levels, namely 0, 7.5, 15, 22.5 g per mound. Observational data were analyzed statistically using analysis of variance. If the calculated F is greater than the F table, then it is continued with a further test of the Honest Significant Difference (BNJ) at the 5% level. Parameters observed were number of tubers per plant, tuber weight per plant, tuber diameter, wet stover weight, tuber weight per tuber, longest tuber length, and tuber proportion per plant. The results showed that the interaction effect of rabbit urine and KCl fertilizer was significant for all observation parameters. The best treatment was a combination of 60 ml of rabbit urine per liter of water and 22.5 g of KCl fertilizer per bund. The main effect of real rabbit urine on all observation parameters. The best treatment is 60 ml rabbit urine per liter of water. The main effect of KCl fertilizer is real on all observation parameters. The best treatment was KCl 22.5 g per bund.
