Abstract

This study aims to determine the nutrient status of the soil and obtain fertilization recommendations based on the results of the analysis of the Rice Soil Test Device (RSTD) in Jerukagung Village, Klirong District, Kebumen Regency. Data collection was carried out by data analysis with RSTD, direct interviews and distribution of questionnaires to farmers who own rice fields. Sample selection is carried out by random sample method (probability sampling). The number of samples taken by 30 farmers from 4 farmer groups who have paddy fields in Jerukagung Village, Klirong District, Kebumen Regency.Based on the test results using RSTD, with a low N content (86.67%) so it needs to be fertilized 250 kg of Urea / ha. The P content is high (86.67%) so it needs to be fertilized 50 kg SP-36/ha. The K content is medium (73.33%) so it needs to be fertilized 50 kg KCl / ha or by using straw as much as 5 tons / ha. The degree of acidity or pH in general is neutral (60%), which is in the range of pH 6-7 so that the recommendation for N fertilization is in the form of Urea with a conventional drainage system.

Abstract

The productivity management of oil palm plantations is carried out by analyzing various influencing factors, but the growing conditions of oil palms are one of the causes of fluctuations in oil palm production. This paper aims to identify post-harvest increases in oil palm productivity. Productivity depends on the number of clusters and the weight of fresh fruit bunches (FFB) produced yearly. The methods of this study were conducted using a targeted sampling technique using available production data for plant time points from 4 to 13 years of age. The total plant sample was 636 ha in Central Kalimantan. As a result, plant growth factors can significantly impact oil palm productivity as measured by the components of oil palm plant production: fresh bunch production per hectare, average bunch weight, and the number of oil palm bunches. FFB tonnage and mean bunch weight increase each year from age 3 to age 13, according to a quadratic regression pattern, whereas the number of palm clusters, in contrast, decreases in number with increasing plant age. This study was intended to serve as a reference and source of information for making production decisions for oil palm plantations to achieve optimal results.
