Abstract

This study aims to examine the combined effects of quail manure and NPK 16:16:16 fertilizer on the growth of oil palm seedlings (Elaeis guineensis Jacq.) in Red Yellow Podzolic soil during the pre-nursery stage. The research was conducted from February to May 2023 at the Experimental Farm of the Faculty of Agriculture, Riau Islamic University in Pekanbaru City. The experimental design utilized a Completely Randomized Design (CRD) with two factors. The first factor involved quail manure at four levels: 0, 200, 400, and 600 g per plant. The second factor consisted of four levels of NPK 16:16:16 dosage: 0, 15, 30, and 45 g per plant. Each treatment was replicated three times. The observed parameters included plant height, number of leaf midribs, stem diameter, wet weight, leaf length, and root length. Statistical analysis was performed, followed by the Honestly Significant Difference Test (BNJ) at a 5% significance level. The interaction between treatments significantly enhanced stem diameter (21.10 mm), plant wet weight (34.88 g), and root length (26.72 cm) with the combination of 600 g/plant quail manure and 45 g/plant of NPK 16:16:16 fertilizer. Quail manure had a significant main effect on all parameters, with the optimal treatment being 600 g/plant. Similarly, NPK 16:16:16 also had a significant main effect on all observed parameters, with the best treatment being 45 g/plant.

Abstract

The development of cauliflower cultivation (Brassica oleracea var. botrytis L.) on marginal land necessitates implementing appropriate cultivation techniques to enhance plant growth and production. In this context, applying organic fertilizers, such as Kasgot and NPK fertilizers, is anticipated to improve the productivity of cauliflower in Riau Province. This study aims to evaluate the effects of Kasgot and NPK fertilizers on the growth and production of cauliflower cultivated on red-yellow podzolic soil. The research was conducted at the UIR Experimental Garden in Pekanbaru from August to December 2024. A Completely Randomized Design (CRD) Factorial was employed for this study. The first factor examined was the dosage of Kasgot fertilizer (K), which included four treatment levels: no Kasgot fertilizer, and Kasgot fertilizer at 100 g, 200 g, and 300 g per polybag. The second factor examined was the NPK fertilizer (N) dose, which included five treatment levels: no NPK, and NPK fertilizer at 3.75 g, 7.5 g, 11.25 g, and 15 g per polybag. Each experimental unit was replicated three times. The results indicated that the data collected, including plant height, age of flower formation, relative growth rate, flower weight per plant, flower diameter, and root volume, were significantly influenced by the interaction between phosphorus fertilizer and NPK fertilizer. The combination of 300 g of Kasgot fertilizer per polybag and 7.25 g of NPK per polybag proved to be the most effective in enhancing the relative growth rate, flower weight per plant, and flower diameter in cauliflower.
