Pengaruh Pupuk Kascing Dan NPK Pelangi 20:10:10 Terhadap Pertumbuhan Dan Hasil Tanaman Seledri (Apium Graveolens L.)

This study aims to determine the main effect and interaction of vermicompost fertilizer and npk Pelangi 20:10:10 on the growth and yield of celery plants. It has been carried out at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Jalan Kaharuddin Nasution Km 11 No. 113. Air Cold Village, Bukit Raya District, Pekanbaru City. The study was carried out for 4 months from October 2021 to January 2022. The design used in this study was a Completely Randomized Factorial Design, consisting of 2 factors. The first factor is Kascing fertilizer consisting of 4 levels, namely 0, 10,4, 20.8 and 31.2 g per polybag and the second factor is NPK Pelangi fertilizer consisting of 4 levels, namely 0, 2,25, 4,5 and 6, 75 g per plant. The parameters observed were plant height, harvest age, number of leaf midribs, wet weight per plant, economic weight per plant, root volume, root crown ratio and harvest index. Observational data were analyzed statistically and continued with the further BNJ test at the 5% level. The results showed that the interaction effect of Kascing fertilizer and Pelangi NPK fertilizer was significant for all parameters except plant height. The best treatment was Kascing fertilizer 31.2 g/polybag and NPK Pelangi fertilizer 6.75 g/plant. The main effect of Kascing fertilizer was significant on all observation parameters. The best treatment for Kascing fertilizer was 31.2 g/polybag. The main effect of Pelangi NPK fertilizer was significant on all observation parameters. The best treatment for NPK Pelangi fertilizer was 6.75 g/plant
