Abstract

This study aims to determine the status of P, K, and C-Organic nutrients in the dry land soil of Pamulihan Dystrictt, Sumedang Regency. The study was conducted to map the status of P, K, and C-Organic nutrients in the dry land of Pamulihan Dystrictt according to the guidelines for using the Dry Land Soil Test Kit (PUTK). The research was carried out from July 2024 to August 2024 in Pamulihan Dystrictt. The research method involved collecting primary data through field surveys, determining the number and location of sample points using random sampling with the ArcGIS 10.8 application, collecting samples at the designated points, and analyzing the chemical properties of the dry land soil in Pamulihan Dystrictt according to the guidelines for using the Dry Land Soil Test Kit (PUTK). Geographic data were collected and analyzed using GIS technology to map the status of P, K, and C-Organic nutrients in the dry land of Pamulihan Dystrictt. The results of the nutrient status testing in the dry land of Pamulihan Dystrictt, particularly in the villages of Cigendel, Citali, Haurngombong, Pamulihan, and Sukawangi, showed low, medium, and high phosphorus (P) levels, predominantly low with an area of 216.29 ha (55%). Potassium (K) testing showed medium and high levels, predominantly medium with an area of 246.14 ha (62.61%). C-Organic testing showed low levels across an area of 393.13 ha (100%). Fertilization recommendations for crops were made based on the nutrient needs of each plant according to the fertilization recommendation guidelines in the Dry Land Soil Test Kit (PUTK). The conclusion of this study is that the nutrient status of dry land in Pamulihan Dystrictt shows low phosphorus (P), medium potassium (K), and low C-Organic levels. The mapping of P, K, and C-Organic nutrient status in the dry land of Pamulihan Dystrictt was done in a semi-detailed map with a scale of 1:50,000.

Abstract

Background. The success of rice production is influenced by many factors, one of which is the selection of varieties. Varieties, as a supporting factor in increasing agricultural productivity, will be able to show values according to potential yields with optimal farming management. Aims. This study aims to examine the differences in agronomic characteristics and kinship of 10 high-yielding inbred rice varieties (Oryza sativa L.) in West Java. The experiment was conducted at the Variety Display Land, Pamekaran Village, Soreang District, Bandung Regency. The experiment was conducted from April to August 2024. The experimental location was situated at an altitude of 700 m above sea level. Methods. The agronomic characteristic experiment method used a qualitative descriptive approach. In the experimental approach, a Randomized Block Design (RBD) was employed with 10 inbred rice phenotype treatments, repeated three times. The materials used in this experiment were 10 high-yielding inbred rice varieties. Result. Based on the study's results, similarities were observed in morphological characters among several inbred rice varieties, including those in Group I, Inpari 32 HDB, and Situ Bagendit, with a similarity level of 100%. In Group II, the Mekongga, Inpari 42, Inpari 33, and Inpari 30 varieties, and in Group III, the Ciherang and Padjadjaran Cakrabuana Agritan varieties, achieved a coefficient value of 78%. Conclusion. The similarity is 0.10 or 100% with a similarity coefficient level of 100% seen from the morphological character data based on the Rice UVOP Table
