Abstract

This study determines the impact of the interaction between Multi KP fertilizer and the duration of scion storage on the growth of sweet orange grafts. The research was conducted at the Experimental Farm of the Faculty of Agriculture at the Islamic University of Riau, located at Jalan Kaharudin Nasution No: 113, Air Cool Village, Bukit Raya District, Pekanbaru. The study spanned three months, from April to June 2022. A Factorial Completely Randomized Design (CRD) was implemented, featuring two primary factors. The first factor was Multi KP Fertilizer, tested at four levels: 0, 2, 4, and 6 grams per plant. The second factor concerned the duration of scion storage, also with four levels: 0, 2, 4, and 6 days. This design resulted in 16 treatment combinations, each replicated three times, totaling 48 plots. From each plot, four plants were grown, and two plants were sampled, resulting in a total of 192 plants for analysis. The findings indicate that the interaction between KP fertilizer and scion storage time significantly influenced all observation parameters. The optimal treatment involved a fertilizer dosage of 6 grams per plant combined with a storage duration of 6 days. Additionally, KP fertilizer alone had a notable positive effect on all observed parameters, with the best results again corresponding to the 6 g/plant dosage. The duration of scion storage also had significant effects across all measured parameters, with the most beneficial duration being 6 days.

Abstract

The decline in land area and the stagnation of cocoa production pose challenges for managing a sustainable cocoa production system, resulting in low plant productivity. One contributing factor is the use of suboptimal cultivation techniques, so improvements must begin at the nursery stage. The study aims to determine the interaction and main effects of Pineapple Peel POC and organic NPK on the growth of cocoa plant seedlings. The study was conducted at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Pekanbaru, from May to August 2025. The study used a factorial Completely Randomized Design (CRD) with two factors. The first factor was Pineapple Peel POC, with four treatment levels: 0, 25, 50, and 75 ml/l of water. The second factor was organic NPK at four levels (0, 10, 14, and 18 g/plant). The parameters observed were cocoa plant height, number of leaves, stem diameter, total leaf area, and root volume. Observation data were analyzed for variance, and the BNJ test continued at the 5% level. Based on the results of the study, the interaction effect of pineapple peel POC and organic NPK was significant for cocoa plant height, number of leaves, stem diameter, total leaf area, and root volume. The best treatment was pineapple peel POC at 75 ml/l in water, with organic NPK at 18 g/plant. The main effect of pineapple peel POC was significant on all parameters, and the best treatment was pineapple peel POC at a concentration of 75 ml/l of water. The main effect of organic NPK was substantial across all parameters; the best treatment was 18 g/plant.
