Abstract

This study aims to determine the growth response of oil palm seedlings in the pre nursery to the type and time interval of urine aplication. The research was conducted at Kebun Pendidikan dan Penelitian Institut Pertanian Stiper Yogyakarta, Maguwoharjo, Depok, Sleman, Yogyakarta Special Region. This research was conducted from November 2022 to January 2023. The study used a factorial experimental design and a completely randomized design (CRD) consisting of two factors. The first factor which consist of four levels namely control (NPK, N), cow urine, goat urine and rabbit urine.  The second factor which consist of three levels namely once every three days, once every five days and once every seven days. There were twelve treatment combinations and repeated five times so that there were sixty plant samples. Using ANOVA (Analysis of Variance) with a significance level of five percent this data was analyzed. Futher test using DMRT (Duncan Multiple Range Test) with a significance level of five percent if there is a significant difference. There was an interaction between the type dan time interval of urine aplication on shoot fresh weight and shoot dry weight. Control (NPK, N) and type of urine had the same effect, meaning that livestock urin could replace chemical fertilizers (NPK, N). The time inteval for giving urine once every seven days was the best compared to once every three days and once every five days.

Abstract

The research was carried out at the Sungai Bungur Estate Plantation (SBGE), PT. Prisma Cipta Mandiri, South Sumatra Region 2, PSM 2 located in Cempaka Sari Village, East Kikim, Lahat Regency, South Sumatra. This research was conducted from March 2023 - April 2023. The research method used to analyze the results of this research was a 2-factor Completely Randomized Design (CRD). The first factor is the type of fertilizer with 3 levels: urea 5 g/polybag, rock phosphate (RP) 50 g/polybag, NPKMg 5 g/polybag. The second factor is the composition of the planting medium with 3 levels: top soil, top soil: 1:1 manure, and top soil: 2:1 manure. Observational data Ade analyzed Alt variance at the 5% level. To find out the differences betwween treatments the Duncan’s Multiple Range Test bas continued St 5% level. The parameters observed were the increase in seedling height, number of leaves, stem diameter, root length, root volume, shoot fresh weight, shoot dry weight, root fresh weight, root dry weight. The results of the analysis show that the combination of applying NPKMg fertilizer with the composition of top soil planting media: manure 2:1 shows that there is a real interaction on the parameters of shoot dry weight, root fresh weight and root dry weight.
