Abstract

Utilization of Coffee Peel Waste Fertilizer and Fertilizer Provision of Hospital 11 on the Growth and Production of Broccoli (Brassica oleracea L.). Who carried out the research in the experimental field of the Faculty of Agriculture, Sisingamangaraja XII University, Tapanuli with an altitude of ± 1400 m above sea level. The research was carried out from June to August 2022.This study was conducted to find out how "Utilization of Coffee Peel Waste Fertilizer and Fertilizer Provision of Hospital 11 on the Growth and Production of Broccoli (Brassica oleracea L.)"The design used in this study was a factorial randomized block design (RAK) with two factors, namely: Factor I: Provision of coffee husk waste fertilizer with 4 levels, namely: L0 = No Treatment (control), L1 = 600 grams / plot, L2 = 1200 grams/plot, L3 = 1800 grams/plot. Factor II: Provision of RS 11 Fertilizer with four treatment levels, namely R0 = No RS 11 Fertilizer (control), R1 = 125 grams / plot, R2 = 250 grams / plot R3 = 375 grams / plot. Thus obtained 16 treatment combinations and treatment with 3 replications. Parameters observed were: plant height (cm), number of leaves (strands), stover weight (kg), flower weight (kg), and flower diameter (cm).The results showed that the application of coffee husk waste fertilizer and RS 11 fertilizer had a very significant effect on plant height (cm), number of leaves (strands), stover weight (kg), flower weight (kg), and flower diameter (cm).The interaction between the application of coffee husk waste fertilizer and RS 11 fertilizer had a very significant effect on plant height (cm), stover weight (kg), flower weight (kg), and flower diameter (cm). coffee husk and RS 11 fertilizer had no significant effect.
