Salah satu upaya peningkatan produksi kedelai di Bengkulu melalui pemanfaatan lahan pesisir. Perbaikan lahan pesisir dilakukan dengan menambahkan pupuk kompos. Agar terpenuhinya kebutuhan hara bagi tanaman kedelai di lahan pesisir perlu kombinasi antara pupuk kompos dan urea. Penelitian itu bertujuan untuk mengetahui keragaan kedelai pada pemberian berbagai jenis pupuk kompos dan dosis urea serta menentukan jenis kompos dan dosis urea terbaik pada lahan pesisir. Penelitian dilakukan pada bulan Juli-Agustus 2020. Penelitian menggunakan rancangan RAKL 2 faktor dan 3 ulangan, faktor pertama jenis pupuk kompos: P1=Widelia trilobata; P2=Tithonia diversivolia; P3= Tandan Kosong Kelapa Sawit (TKKS), P4=Eceng gondok. Faktor kedua yaitu dosis pupuk Urea: N0=0 kg.ha-1, N1=25 kg.ha-1, N2=50 kg.ha-1, N3 = 75 kg.ha-1. Kedelai yang digunakan adalah varietas Direng 1. Hasil penelitian diperoleh bahwa jenis pupuk kompos dan dosis pupuk urea tidak berbeda nyata pada variabel keragaan tanaman kedelai. Pemberian 4 jenis pupuk kompos sebanyak 10 ton.ha-1 di lahan pesisir menunjukkan pertumbuhan yang kurang baik dan hasil sedikit. Pupuk kompos Thitonia memberikan hasil paling tinggi sebanyak 0,5 ton.ha-1 dan sebanyak 0,48 ton.ha-1 pada pemberian urea 75 kg.ha-1. Hasil kedelai masih sangat rendah sehingga perlu peningkatan dosis urea dua kali lipat di lahan pesisir. Kata kunci : Direng 1, kompos, lahan pesisir dan urea

Soybean is one of the secondary crops that has a good economic value. Soybean needs are increasing with increasing population, but production is not sufficient. Extensification programs can be carried out in sub-optimal swamp swamps with water saturated cultivation technology. Low pH and high Al and Fe are the main obstacles. One of the strategies taken is the provision of coral ameliorants. The aim of this study was to obtain information on the effectiveness of coral reefs to improve the cultivation of black soybean in swamp swamps. The study was conducted in March - May 2018 at the Experimental Garden of the Faculty of Agriculture, University of Ratu Samban Arga Makmur Bengkulu Utara. The study used a randomized block design with factorial patterns. The first factor in the dose of ameliorant per plant consisted of: P0: control, P1= 5 g, P2 = 6 g, P3= 7 g, P4= 8 g, P5= 9 g, P6= 10 g. The second factor when the ameliorant application consists of: W1= 4 weeks before planting (MBT), W2 = 3 MBT, W3 = 2 MBT, W4 = 1 MBT, W5= when planting, W6= 1 weeks after panting. The results showed that the treatment of the dose and time of application of coral ameliorants had a very significant effect on plant height and number of leaves. There is no real interaction between the dose and time of ameliorant application to all variables. The best dose of ameliorant treatment is 9 g per plant and can increase the height and number of leaves per plant. When the application of 1 MBT and 1 MST is able to produce the best height and number of leaves.

Green biomass is one of major nutrient source and determines the quality of liquid organic fertilizer (LOF), including Gliricidia sepium (Jacq.) Kunth ex Walp. An experiment was conducted to study the effects of Gliricidia-enriched LOF on growth and yields of caisim, arranged in randomized complete design with three replicates. Treatments consisted of six LOF concentrations, 0%, 20%, 40%, 60%, 80% and 100%. Results indicated that concentration of gliricidia-LOF significantly influenced leaf greenness and shoot fresh weight, but not root to shoot ratio and shoot water content. Concentrations of gliricidia-LOF increased leaf greenness and shoot fresh weight of caisim. The optimum concentration was 70.85% to produce weight of 73 grams caisim per plant. Root to shoot ratio was not significantly different. Although treatments did not affect shoot water content, all caisim water content was on average above 90 %.

This research aimed to determine the effect of media composition leather waste coffea bokashi fertilizer on the growth of coffee seedlings in the nursery playing robusta nursery and determine the best composition that can replace the use of chemical fertilizer in the coffee nursery. This research was conducted in vilage Tugu Rejo subdistrict Kabawetan Kepahiang district Bengkulu province. This study uses a completely randomized design (CRD) of the factors with 6 (six) treatment that the composition of the growing media bokashi (P). Each composition treatment was repeated four (4) times, in order to obtain 24 units of trial. Each experimental unit there are five (5) polybags, so there are 120 polybags. Each experimental unit was taken three (3) samples. These result indicate that treatment of bokashi fertilizer media leather waste coffe very significant effect on the dry weight of coffee seedlings, significant effect on plant height and weight of the wet, and no real effect on the number of leaves and stem diameter. Effect of medium composition leather waste coffe bokashi fertilizer best demonstarted high value crops 13.63 cm, wet weight of 1.82 g and 0.60 g dry weight. The use of leather waste coffee bokashi fertilizer is able to substitute inorganic fertilizer on seedling nursery play. The use of media with the composition of the piece of land sub soil mixed with four parts bokashi leather waste robusta coffee in the coffee nursery on the main nursery gives good results.
