Long bean production in Indonesia continues to decline every year, this is due to land conversion and the lack of application of agricultural technology. One of the efforts to increase long bean production is by multiplying quality seeds using organic materials as nutrients needed by plants. This study aims to determine the response of the growth and production of long bean seeds to the interaction of strains, varieties with a concentration of liquid organic fertilizer. The research was conducted at the Vegetable Crops Research Institute, Lembang, West Bandung Regency from July 2020 to January 2021. The research method used was an experimental method with a Randomized Block Design (RBD) with a split-plot design consisting of 2 factors: the first factor (main plot) (A) was the variety and strain with 2 levels, a1 (Tavi canton variety) and a2 (pras-1 strain).The second factor (subplot) (B) is concentration of biopras-1 with 5 levels, b1 (0 cc/l-1 water), b2 (1 cc/l-1 water), b3 (2 cc/l-1 water), b4 (3 cc/l-1 water) and b5 (4 cc/l-1 water). The effect of the treatment was analyzed by means of variance and if the f test at 5% level was significantly different, then to find out the best treatment was continued with the DMRT (Duncan Multiple Range Test) at the 5% level. The results showed that there was an interaction between varieties, lines with various concentrations of biopras-1 liquid organic fertilizer on dry seed weight per plant, dry seed weight per plot, and 1000 seeds weight. Treatment of pras-1 lines with the concentration of liquid organic fertilizer biopras-1 4 cc / l of water was able to give the best results on dry seed weight per plant (35.31 gr), dry seed weight per plot (1.298.20 gr or 2.16 Ton/ha-1) and the weight of 1000 seeds (153.10 gr).

<p>The physical and chemical properties of the growing medium for <em>root trainer</em> of rubber are critical to support plant growth. This study aimed to obtain the best medium for growing rootstock rubber seedlings in the <em>root trainer</em>.  Rubber clone PR 300 seeds were germinated for 21 days, then raised in <em>root trainer</em> pots for five months. The treatments evaluated were a mixture of <em>cocopeat</em>, Rawapening peat, and manure at different ratios.  The experiment was designed in a Randomized Block Design, three replications, 30 plants per replicate, totaling 720 plants. The observed variables were N, P, K, Mg, C-organic content, pH, and cation exchange capacity of <em>cocopeat</em>, peat, and manure, as well as plant growth (height, stem diameter, wet weight, and dry weight). ANOVA used for analyzing data, followed with the <em>Duncan Multiple Range Test</em> at 5% level. The results showed that there were three best <em>root trainer</em> media for PR 300 rubber rootstock seedlings were a mixture of <em>cocopeat</em> + peat (1:1), <em>cocopeat</em> + peat + manure (1:2:1), and <em>cocopeat</em> + peat + manure (2:1:1). The growth and compactness of the roots are outstanding, so the seedlings are easily removed from the <em>root </em><em>trainer</em> pots without significant damage. Based on the initiation and cost, the best <em>root trainer</em> medium is a mixture of <em>cocopeat</em> + peat + manure (1: 2:1). It is necessary to study the use of other types of peat soils apart from Rawapening. Also, it needs to be observed further plant growth after inoculation with the stem and after planting in the field.</p><p><strong>Keywords </strong>: Planting medium, Rawapening peat, rubber clone PR 300.<em></em></p><p><em><br /></em></p><p><strong>Abstrak<br /></strong></p><p>Sifat fisik dan kimia media tanam di dalam wadah <em>root trainer</em> bibit karet sangat penting untuk mendukung pertumbuhan tanaman.

Penelitian yang bertujuan untuk mengetahui pengaruh bahan organik (kompos gamal, dan asam humat) serta FMA (Glomus sp. + Gigaspora sp.+ Aclauspora sp) terhadap pertumbuhan serta hasil tanaman cabai pada tanah pasca galian C telah dilaksanakan di Gapoktan Simpay Tampomas, Sumedang sejak bulan Februari sampai dengan Juli 2014. Metode yang digunakan merupakan metode eksperimental berupa Rancangan Acak Kelompok (RAK),  dengan 8 perlakuan dan 4 kali ulang: a0 = kontrol, a1 = kompos gamal 5 t ha-1, a2 = kompos gamal 10 t ha-1, a3 = aplikasi FMA, a4 = asam humat, a5 = kompos gamal 5 t ha-1 + FMA , a6 =  kompos gamal 10 t ha-1 + FMA, dan a7 = aplikasi asam humat + FMA. Pengujian lanjut dilakukan dengan Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa aplikasi kompos gamal, asam humat, dan FMA tidak berpengaruh nyata terhadap diameter batang dan bobot segar buah, tetapi berbeda nyata terhadap tinggi tanaman. Pengaplikasian bahan organik hingga 10 t ha-1, asam humat, dan FMA belum berpengaruh nyata terhadap perbaikan kesuburan tanah pasca galian C (tambang pasir), karena kondisi tanah pasca galian C yang didominasi 75% pasir dan 50% batuan. The study which aimed to determine the effect of organic matter (gliricidia compost, and humic acid) also AMF (Glomus sp. + Gigaspora sp. + Aclauspora sp.) on growth and yield of chili plants on post-excavation soil C had been held in Gapoktan Simpay Tampomas, Sumedang from February to July 2014. The method was an experimental method a randomized block design (RBD), with 8 treatments and repeated 4 times: a0 = control, a1 = gliricidia compost 5 t ha-1, a2 = gliricidia compost 10 t ha-1, a3 = AMF, a4 = humic acid, a5 = gliricidia compost 5 tons ha-1 + AMF, a6 = gliricidia compost 10 tons ha-1 + AMF, and a7 = humic acid + AMF. Further testing was done by Duncan Multiple Range Test (DMRT). The results showed that the application of gliricidia compost, humic acid, and AMF did not significantly affect stem diameter, and fresh weight of fruit, but significant on stem height. Application of organic matter up to 10 tons ha-1, humic acid, and AMF had not significantly affect fertility improvement of post-excavation soil C (sand mining), because the soil C dominated by 75% sand and 50% rock.
