Abstract. Setyaningrum D, Suhita CP, Paryanto E, Ningsih H, Arifin Z, Suryadi D, Suprihatin DN, Nurhidayati F, Pradana AGR, Hantari D. 2025. Effect of organic fertilizer types and dosage on yield and nutrient uptake of red ginger in an Alfisol. Asian J Agric 9: 636-644. Declining red ginger production in Indonesia, partly due to reduced optimal land availability, has prompted the use of suboptimal soils, such as Alfisols are known to be fertile soils with relatively high concentrations of essential nutrients. This study evaluated the effects of animal manure type (cow, goat, and chicken) and application dosage (0, 10, 20, and 30 tons.ha-¹) on yield performance and nitrogen (N), phosphorus (P), and potassium (K) uptake of red ginger (Zingiber officinale var. rubrum) in Alfisol. A randomized complete block design with a split-plot arrangement was applied. Results showed that both manure type and dosage significantly influenced yield and nutrient uptake. Goat manure at 30 tons.ha?¹ produced the highest fresh weight, biomass, rhizome weight, and N and P uptake. Rhizome weight and volume were positively correlated with N and P uptake, indicating that improved nutrient absorption efficiency contributed to yield enhancement. Increasing manure dosage consistently elevated biomass, rhizome volume, and K uptake, with optimal results at 30 tons.ha-¹. These findings demonstrate that organic fertilization, particularly with goat manure at 30 tons.ha-¹, is an effective strategy to boost red ginger productivity and nutrient use efficiency on marginal Alfisol soil. The approach supports sustainable cultivation and could help meet increasing market demand, although long-term impacts on soil health require further investigation.

Abstract

Chinese betel is a plant widely found in Indonesia, especially in the ex-Karasidenan area of Surakarta. The existence of growing Chinese betel can be found at various altitudes with humid growing conditions with low sun intensity. People in Surakarta believe that Chinese betel can be used as a traditional medicine. Chinese betel nut is suspected to contain a minerals and bioactive substances that are beneficial to health. Currently, there are few references to Chinese betel, especially related to genetic diversity. This study aims to study the diversity of Chinese betel band patterns based on RAPD markers using OPA-3, OPA-4, OPA-11, OPC-05, and OPD-4 primers. This research was carried out at the Plant Breeding Laboratory, Faculty of Agriculture, Gadjah Mada University, Yogyakarta in July - November 2023 using Chinese betel leaf DNA taken from various places in the ex-karasidenan area of Surakarta. The results of the data analyzed by NTSYSpc version 2.02 with the SimQual (Similarity for Qualitative Data) function using the UPGMA (Unweighted Pair Group with Arithmetic Averaging) method based on the Jaccard similarity index value. The amplification results showed 30 bands with 13 polymorphic bands and 17 monomorphic bands. The level of polymorphism among Chinese betel samples in the five RAPD primers used presented 44.36% of the total 13 polymorphic bands. Jaccard's genetic similarity matrix data ranged from 0.667 – 0.964. The results of the dendogram show that the sample is divided into two clusters with a diversity index of 0.28.
