Abstract

This study aims to determine the interaction effect as well as the main effect of palm oil wastewater and grand-K on cabbage yields. The research was carried out in a community garden, Jalan Kusuma Bakti, Air cold Village, Bukit Raya District, Pekanbaru City. The research was carried out for 4 months, from June to September 2021. This study used a factorial Completely Randomized Design (CRD) which consisted of 2 factors, namely the first factor of palm oil liquid waste (L) consisting of 4 treatment levels, namely 0, 150, 300 and 450 ml/plant. The second factor Grand-K (K) consists of 4 treatment levels, namely 0; 1.25; 2.50; and 3.75 g/plant. Parameters observed were crop formation age, harvesting age, plant fresh weight, fresh crop weight and head circumference. Observational data were analyzed statistically and continued with the BNJ test at the 5% level. The results showed that the interaction of palm oil wastewater and grand-K fertilizer had a significant effect on the parameters of crop formation age, harvesting age, fresh weight of plants, fresh weight of heads and girths of heads. The best treatment was a combination of 450 ml/planting of palm oil liquid waste and 3.75 g/planting of Grand-K fertilizer. The main effect of palm oil liquid waste is real on all observation parameters. The best treatment of palm oil wastewater with a dose of 450 ml/plant The main effect of grand-K fertilizer was significant on all observation parameters. The best treatment of grand-K with a dose of 3.75 g/plant
