Abstract

The research titled "Application of Broiler Chicken Boiling Waste and Arbuscular Mycorrhizal Fungi (AMF) on Growth and Production of Lowland Cauliflower Variety Larissa F1 (Brassica oleracea var. Botrytis L.)" aims to determine the effect of the application of broiler chicken boiling waste and Arbuscular Mycorrhizal Fungi (AMF) on the growth Cauliflower. The research was conducted at the Experimental Farm, Faculty of Agriculture, Islamic University of Riau, Jalan Kaharuddin Nasution Km. 11, No. 113, Air Dingin Village, Bukit Raya District, Pekanbaru City. The research was carried out over 3 months, from June 2024 to August 2024. The experimental design used in this study was a Factorial Randomized Complete Design consisting of two factors. The first factor was the concentration of chicken boiling waste, which included 4 levels, and the second factor was the dose of Arbuscular Mycorrhizal Fungi, which included 4 levels, resulting in 16 treatment combinations. Each treatment combination was replicated 3 times, making a total of 48 experimental units. Each experimental unit consisted of 9 plants, with 6 plants sampled per unit, resulting in a total of 432 plants. The observed parameters were plant height, number of leaves, flowering age, relative growth rate, net assimilation rate, harvest age, weight of flower and leaves, weight of flowers, root volume, percentage of head weight to plant weight, and root-to-shoot ratio. Data were statistically analyzed and followed by a Honest Significant Difference (HSD) test at the 5% level. The results showed that the interaction of the application of broiler chicken boiling waste and Arbuscular Mycorrhizal Fungi (AMF) significantly affected plant height, number of leaves, flowering age, harvest age, economic flower weight, and flower weight. The best treatment was the application of chicken boiling waste at a concentration of 15 cc/l water and Arbuscular Mycorrhizal Fungi at a dose of 30 g/polybag. The application of chicken boiling waste was significant for all observed parameters, with the best concentration being 15 cc/l water. The main effect of Arbuscular Mycorrhizal Fungi was also significant for all observed parameters, with the best dose being 30 g/polybag.
