Abstract

The purposes of this research are (1) to know the influence of genotype and biological fertilizer to the soil biological properties, and (2) to know the influence of genotype and biological fertilizer to the soybean plants productivity at its ultisols. This experiment was conducted at experimental garden of Bengkulu University. It was arranged in factorial split plot design and consisted of two factor. The first factor was soybean cultivars i.e. Pangrango, Ceneng, and DS1 (Malabar and Kipas Putih variety breeding). The second factor was double inoculation of Rhizobium and VAM i.e. Glomus manihotis + Rhizobium of KLR 5.3 strain, Glomus manihotis + Rhizobium of TER 2.2 strain, Gigaspora margarita + Rhizobium of KLR 5.3 strain, Gigaspora margarita + Rhizobium of TER 2.2 strain, fertilizer NPK at recommended dosage without inoculants respectively. The collected data was analyzed statistically and tested by F test at level of 5% and continued with Duncan Multiple Range test for differences among the treatments. The result of the research showed that (1) the soil that had been planted genotype DS1 soybean has the highest level of C-Organic (2,69%) compare with pangrango or ceneng and biological fertilizer produces higher level of respiration than its control. (2) ceneng’s genotype produce the effective amount of nodules, plant dry weight (3,90 g), and seed weight (5,66 g) is higher than if we compare with pangrango and DSI.Keywords : soybean, biofertilizer technology , Ultisols

Abstract

Soil water availability to the plants is a range of water content between the field capacity and the permanent wilting point (PWP) conditions. The PWP is defined as the lower limit of soil water content that the plant can extract water from the soil as indicated by the symptoms of wilting plants. This is because plant roots are unable to penetrate the soil micropores that contain the water.  The study aims to analyze the effects of arbuscular mycorrhizal fungi (AMF) and compost in enhancing soil water absorption by the plant when the water content is close to the permanent wilting point. Four doses of AMF (0, 5, 10 and 15 g.plant-1) and three doses of coffee pulp-made compost (0, 5 and 10 ton.ha-1) were arranged according to a randomized complete block design with three replicates. Results showed that the application of AMF significantly enabled the plant to improve water uptake when the soil water content was about at the permanent wilting point conditions. The AMF addition of 15 g.plant-1 significantly prolonged the growing period of chili to wither and the plant showed the wilting symptoms at the soil water content of 5 to 7% lower than the no-AMF plants. Improved water uptake under water stress conditions was attributed to increases in the root colonization by AMF.

Abstract

Selama ini kawasan pesisir yang terletak di Kelurahan Beringin Raya kurang termanfaatkan untuk budidaya pertanian dan sebagian dibiarkan menjadi semak belukar, meskipun sebagian besar masyarakatnya berprofesi sebagai petani. Hal ini karena kawasan pesisir memiliki tanah dengan karakteristik yang kurang mendukung untuk pertumbuhan komoditi pertanian. Oleh karena itu, diperlukan teknologi khusu agar tanaman bisa tumbuh dan berproduksi dengan baik di kawasan pesisir, salah satunya adalah apliaksi pupuk hayati. Kegiatan pengabdian ini bertujuan untuk meningkatkan pengetahuan masyarakat mitra tentang pupuk hayati dan aplikasinya melalui penyuluhan dan pelatihan serta pendampingan. Luaran yang dicapai dalam pengabdian ini adalah meningkatnya pengetahuan Kelompok Tani Wanita Rezeki Bersama  tentang pupuk hayati dan aplikasinya terhadap tanaman kedelai. Selain itu, adanya kegiatan pengabdian mampu membuat anggota KWT berminat untuk menanam kedelai menggunakan pupuk hayati. Anggota kelompok KWT juga telah bisa mengaplikasikan pupuk hayati.

Abstract

Soil Quality Index (SQI) assessment is a crucial parameter for evaluating the effectiveness of land reclamation objectives. This research aimed to analyze trends in soil quality changes across various stages of post-coal mining reclamation. This research was conducted in June 2024 at sites with varying soil ages at PT Inti Bara Perdana and in natural forest areas. This research employed descriptive-exploratory methods and involved open-field surveys. Sampling was conducted using purposive sampling at locations representative of the conditions at each site. Principal Component Analysis (PCA) was utilized to identify key indicators and determine the SQI. The results demonstrated that post-mining land reclamation significantly improved the physical, chemical, and biological quality of the soil. While the reclaimed soil quality has not yet fully reached the level of natural forest soil, the reclamation process exhibits strong potential for ecosystem recovery. SQI analysis revealed an increasing trend in soil quality as the reclamation age advanced. Linear variable analysis indicated a positive correlation between reclamation age and SQI development. Reclaimed areas aged 7 and 11 years exhibited SQI values exceeding 0.5, signifying successful reclamation and ecological sustainability.
