Abstract

Achievement and Success in Increasing Plant Growth is by Fertilising the Right Target and Method. Optimisation with inorganic fertilization may not be successful if the soil is not sufficient in nutrients. To fertilise the soil, it must be done by giving organic material, so that the soil is fertile. We are a large-scale manufacturer specialising in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment. Therefore, the right target, method and dose will determine the growth and development of palm oil plants in the Main Nursery. The research was conducted at the Field Laboratory of Soil Management, Conservation at the Institut Teknologi Sawit Indonesia, Medan. Soil Observations at the Soil, Plant, Fertilizer and Water Laboratories at the Agricultural Technology Assessment Centre, Johor, Sumatera Utara. The data results show that the parameters of Plant Height, Stem Circumference, Number of Leaf Sheaths and Leaf Sheats Length have the highest average numbers in the pocket Method, as well as in the Fresh Weight of Roots, Crowns, Dry Weight of Roots, Crowns also have the highest average numbers in the Pocket Method compared to the Sow, Sachet and Drip Fertigation Methods. This indicates that the growth of seedlings of PPKS 718 and PPKS 239 varieties is best in the Pocket Fertilization Method rather than the Sow, Sachet, and Drip Fertigation Methods.

Abstract

Plant growth response of palm oil seedlings (Elaeis guineensis Jacq.) on D x P Yangambi varieties using biochar applications made from palm oil shells, rice husks, and corn cobs in the Main Nursery. This study aims to determine the effect of the application of several types of biochar on the growth of palm oil seedlings (main nursery) on soil chemical properties namely C-Organic, N-Total, Phosphorus Nutrients, Potassium Nutrients and Soil pH in Vertisol Soil Planting Media. This research was conducted at the Soil Laboratory Practice Farm of the Indonesian Institute of Palm Technology, Medan, North Sumatera. The research used Factorial Randomised Group Design (RGD) with 3 replications. The research was conducted for 4 months. The results showed a significant effect on the application of rice husk biochar, palm oil shells and palm oil cobs and the application of N.P.K.Mg 15.15.6.4 fertilizer at a fertilizer dose of 7.5 g.polybag-1 on the parameters of plant height, stem circumference, number of leaf midribs, and biochar treatment can increase soil pH, Phosphorus nutrients, and Potassium nutrients.
