Abstract

The research, conducted from January to September 2023, aimed to map land suitability classes for nutmeg plant development. The evaluation results are presented descriptively and involve three main stages: pre-survey, field survey, and tabulation with data analysis. Primary data collected for this research include soil analysis results from the laboratory, complemented by secondary data. The determination of land suitability utilizes matching techniques for each land characteristic. The actual land suitability results for nutmeg in Rimbo Pengadang and Topos Districts are categorized as follows: S3eh (37.77%) 14,460.93 ha, with the limiting factor being erosion hazard. S3na eh (37.07%), 14,175.10 ha, with limiting factors related to nutrient availability and erosion hazards, S3na (6.77%): 2,592.64 ha, with limiting factors in nutrient availability, S2wa nr na eh (5.34%): 2,044.04 ha, facing limitations in water availability, nutrient retention, nutrient availability, and erosion hazard, S3rc eh (1.30%) 499.43 ha, with a limiting factor for rooting media and erosion hazard, S3rc (0.90%): 346.35 ha, with a limiting factor in rooting media and N (not suitable) (9.10%) 3,484.74 ha. Regarding potential land suitability, the classes are as follows: S1 (44.89%) 17,186.07 ha, S2 (43.80%) 16,767.80 ha, S3rc (2.21%) 845.79 ha, and S3 (9.10%): 3,484.74 ha. The areas with potential for developing nutmeg plants in Rimbo Pengadang and Topos Districts, Lebong Regency, include secondary forest, mixed dry land farming, open land, and bushes.

Abstract

Indonesia, endowed with diverse medicinal plants, is exploring the commercial cultivation of peppermint plants (Mentha arvensis L.) to meet increasing demand for peppermint oil. This study investigated the effects of various natural plant growth regulators (PGRs) on peppermint plant growth and yield. Conducted in Bengkulu City from December 2020 to March 2021, the study used a Completely Randomized Design with 9 treatments of natural plant growth regulators and 3 replications. Results indicated that natural PGRs, including extracts from mung bean sprout filtrate, corn, shallots, and young coconut water, influenced leaf and tiller growth but showed no significant effects on plant height, number of branch shoots, stem segments, stolon, roots, leaf size, or essential oil aroma concentration. The combination of mung bean sprout filtrate and shallot filtrate yielded the greatest number of leaves. The findings suggest that while natural PGRs can enhance specific growth parameters, their overall impact on peppermint plant development may be limited by optimal soil conditions and nutrient availability. เว็บสล็อต Keywords: peppermint, natural PGRs, leaf growth, mung bean sprouts, shallot extracts
