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 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.

Abstract

Soybeans (Glycine max (L.) Merrill) are a popular food commodity in Indonesia, but domestic production is still insufficient to meet the demand. To increase production, planting superior varieties on coastal land could be a viable solution. Despite the challenging biological, physical, and chemical conditions of coastal land, nutrients such as phosphorus (P) are crucial for enhancing production. Typically, the phosphorus content in the soil is lower than that of nitrogen (N) and potassium (K), and the ability of soybean plants to absorb phosphorus varies among varieties. This research aims to compare the growth, yield, and phosphorus uptake of four soybean varieties on biocomposted coastal land. The study was conducted using a Randomized Complete Block Design (RCBD) with a single factor consisting of four soybean varieties: Wilis, Anjasmoro, Malika, and Detam 1. The results indicate that the Anjasmoro, Wilis, Detam 1, and Malika varieties exhibit similar responses in phosphorus absorption. However, the Anjasmoro and Wilis varieties demonstrate better adaptability compared to Malika and Detam 1, as evidenced by their superior growth and yield. This suggests that Anjasmoro and Wilis have a higher capability to adapt to the challenging conditions of coastal land. Therefore, these two varieties are recommended for cultivation in coastal areas to boost soybean productivity, ensuring the sustainability and stability of the national food supply.

Abstract

Pemanfaatan lahan kering pada kawasan pesisir untuk budidaya tanaman padi gogo mempunyai potensi besar untuk pemantapan swasembada pangan maupun untuk pembangunan pertanian kedepan. Keterbatasan kesuburan yang dimiliki lahan di kawasan pesisir dapat diatasi dengan menggunakan teknologi yang tepat seperti penggunaan varietas yang unggul dan pupuk hayati serta biokompos. Penelitian ini bertujuan untuk mengetahui karakteristik biologi dan kimia tanah serta pertumbuhan padi gogo di kawasan pesisir. Rancangan percobaan yang digunakan adalah rancangan petak terbagi dengan petak utama adalah 3 varietas padi gogo yang didapatkan dari BPTP Bengkulu yaitu varietas Inpago 10, Serantan, dan Lokal Bengkulu, dengan anak petak yaitu inokulan ganda mikroba pelarut P (pf) + mikroba pelarut K + mikroba pemfiksasi N, inokulan ganda mikroba pelarut P (fma) + mikroba pelarut K + mikroba pemfiksasi N, biokompos dengan dosis 10 ton ha-1, dan pupuk anorganik rekomendasi BPTP yaitu 200 kg Urea/ha, 100 kg SP36/ha, 100 kg KCl/ha, diulang 4 kali. Hasil penelitian menunjukkan bahwa aplikasi pupuk hayati maupun biokompos yang ditanami padi gogo varietas Inpago 10 di area pesisir mampu meningkatkan karakter biologi dan kimia tanah. Padi gogo varietas Serantan dengan aplikasi inokulan ganda mikroba pelarut P + mikroba pelarut K + mikroba pemfiksasi N di area pesisir mampu menghasilkan jumlah anakan tinggi dengan tinggi tanaman rendahKata kunci: adaptabilitas, lahan pesisir, padi gogo, pertumbuhan, pupuk hayati.
