Abstract

Rubber plants (Hevea brasiliensis Muell. Arg) have an important role for the Indonesian economy, where the area of ​​rubber plantations in Indonesia reaches 3.6 million hectares. The low productivity of rubber plants in Indonesia, it is necessary to increase the productivity of rubber through the provision of seeds for the propagation of rubber plants. The use of POC in Gamal leaves can encourage good rootstock growth with optimal roots, because Gamal leaf tissue contains 3.15% N, 0.22% P, 2.65% K, 1.35% Ca and 0.41% Mg. The aim of this study was to determine the effect of giving Gamal leaf liquid organic fertilizer on rubber rootstock seedlings of clone PB 260. This research was conducted in the experimental garden of the Ketapang State Polytechnic, Jl. Rangga Sentap Dalong, Sukaharja Village, Delta Pawan sub-district, Ketapang district, West Kalimantan, from October 2021 to January 2022 at the Ketapang State Polytechnic. This study used a non-factorial Completely Randomized Design (CRD) with 6 treatments and 4 replications with 3 plant samples so that 72 seedlings were obtained. Observation parameters included plant height (cm), stem diameter (mm), root length (cm) and plant dry weight (g). The results showed that the treatment of LOF of Gamal leaves on rubber rootstock seedlings treated with P5 (400 mL of POC of Gamal leaves + 500 mL of water/polybag) was able to increase the growth of plant height, stem diameter and root length.

Abstract

Oil palm (Elaeis guinensis Jacq) is a crop that is a top priority in plantations in Indonesia. Peat soil as a nursery medium faces many obstacles such as physical and chemical properties that are less supportive for plant growth. Oil palm janjang ash (AJKKS) is an ameliorant that can increase the uptake of macronutrients P, K, Ca and Mg so as to improve the physical and chemical properties of peat soil. This study aims to determine the effect of oil palm empty fruit bunch ash on the growth of oil palm seedlings on peat media. The study was conducted at the Ketapang State Polytechnic, from January to March 2022. This study used a non-factorial completely randomized design (CRD) consisting of 5 treatments and 6 replications. Treatment D0 (AJKKS 0 g/polybag), D1 (AJKKS 150 g/polybag), D2 (AJKKS 250 g/polybag) D3 (AJKKS 350 g/polybag) D4 (AJKKS 450 g/polybag). Parameters observed were peat soil pH, seedling height (cm), number of leaves (strands), stem diameter (mm), root volume (mL), and seedling dry weight (g). The provision of 450 g/polybag AJKKS had a significant effect on the growth of oil palm seedlings on peat soil pH, seedling height, number of leaves, stem diameter, root volume, and plant dry weight.
