Abstract

Taro (Colocasia esculenta L. Schott) is a plant that has an excellent economic and healthy value, as well as a great potential development of Bengkulu coastal area. That is because taro has wide adaptability, and can be consumed both as a staple food and healthy food alternative. This research was conducted to study the vegetative growth of two cultivars of taro given four different doses of nitrogen. This study applied a Randomized Complete Block Design (RCBD) with two factors. The first factor was the cultivar of taro consisted of two levels, namely Taro Satoimo (T1) and the Taro Local (T2). The second factor was the doses of nitrogen fertilizer which consisted of four levels namely: N0 = 0 kg / ha (control), N1 = 50 kg / ha (2.6 g, N2 = 100 kg / ha, and N3 = 150 kg / ha. Thus, obtained eight treatment combinations. Each treatment was repeated three times to get 24 plots. The results showed that based on increased vegetative growth, the cultivar Satoimo has a faster response than local cultivar. Satoimo has demonstrated another advantage because it produced some leaves and number new shoot. The best dose of nitrogen fertilizer on the vegetative growth of taro in the coastal area of Bengkulu is 150 kg/ha.

Abstract

Growing lettuce on lowland mineral soil is an alternative to increase lettuce production. Mineral soil with less fertile soil property needs additional organic matter when it is used as growing medium for lettuce plants . The purpose of this study was to evaluate the growth and yield of lettuce on some mineral soil types and different doses of cow manure. The research was conducted in Surabaya village, Sungai Serut District, Bengkulu City. The experiment used a completely randomized design, two factors, five replications. The first factor was the three types of mineral soils, consisted of Inceptisol, Ultisol and Entisol. The second factor was dose of cow manure, consisted of 0 ton/ha, 5 ton/ha (7.065 g/polybag), 10 ton/ ha (14.13g/polybag), and 15 ton/ha (21.19 g/polybag ). Each combination was repeated 5 times in order to obtain 60 experimental units. The results showed that the mineral Ultisol generally resulted in better growth of lettuce plants than it was at Inceptisol and Entisols, which were indicated by the higher degree of the leaf greenness leaves, root fresh weight and shoot fresh weight. Dosage of fertilizer up to 15 tonnes/ha significantly increased shoot fresh weight and root fresh weight of plants. The interaction between soil types and doses of cow manure occured only on the variable of root fresh weight when it was grown on Ultisol with dose of cow manure at 8.07 tonnes/ha.

Abstract

Planting wetland paddy by setting row space could be a method to increase rice production. Legowo system is row planting method where we are able to apply different row types on paddy field. The objective ofthis research was to identify the best row planting type of ?Jajar Legowo? on growth and yield of wetland paddy. Six row plantings, including 2:1 type (means 2 rows are splited by wide space/ legowo), 3:1 type, 4:1 type, 5:1type, 6:1 type, and 7:1 typ, were tested in a Randomized Complete Block Design with 3 replications Results of the experiment revealed that the highest growth and yield as showed by total number of tillers (28), number ofproductive tillers (25), dry-mill rice (66.16 g per plant), and yield difference of dry-mill rice (50.43% per plot) was found at row planting type 2:1. Therefore, row planting type 2:1 can be selected as the best row.

Abstract

Elaeisponic is new introducing growing technique to produce vegetables by planting it in the frond based of oil palm trees (Elaeis guineensis Jacq.). However, there was no previous report on vegetable production by using elaeisponic production system, including the use of foliar fertilizers. This study aimed to determine the optimum consentrations and frequency of foliar fertilization for caisim grown in elaesisponic production system. An experiment was conducted in oil palm plantation area by using a factorial randomized complete block design with three replicates. The first factor of treatment consisted of three levels of foliar fertilizer concentration, 1 g l-1, 2 g l-1 and 3 g l-1, and the second factor was application frequency of foliar fertilizer, 7 days after transplanting (DAT), 7, 14 DAT and 7, 14, 21 DAT. Crop responses were determined on leaf greenness (SPAD index), shoot fresh weight (g), root fresh weight (g), leaf area (cm2) and plant dry weight.  Results indicated that both concentration of foliar fertilizer and frequency of application as wells as its interaction did not significatly affect leaf greenness, leaf area, shoot fresh weight, root fresh weight and plant dry weight of caisim plants.  Further research should be addressed on optimizing the use of palm oil frond bases as growing medium for vegetable production.  Keywords: Elaeisponic Production System; Brassica juncea L; Foliar Fertilizer; Frequency of Application.

Abstract

The increasing demand for soybean is driven by population growth and development of industry. The current import of soybean should be considered as pragmatic solution to fill the gap between supply and demand. In the long term, the domestic production of soybean has to be increased to minimize the dependency on imported soybean. As part of soybean breeding program for yield improvement, this study was undertaken to evaluate the performances of five elite lines (11 AB, 13 ED, 14 DD, 19 BE, and 25 EC) derived from cross of Malabar and Kipas Putih as compared to their parental varieties and Tanggamus (commercial variety). The evaluation was set up in a completely randomized block design with three replications. Significant variations among the genotypes were found on plant height, flowering date, number of fertile node, hundred seed weight, plant biomass, and protein and lipid contents, but not on number of productive branch, maturity date, pod number, yield per plant, and yield per plot. In most cases, the evaluated lines had intermediary performances between their parental varieties, although some lines produced earlier flowering, larger seed, higher protein content, and lower lipid content. 11 AB exhibited a superiority over its parental and Tanggamus in term of plant biomass and protein content.

Abstract

Hybrid corn cultivated on Ultisol performs high production when organic matter and liming are incorporated into the soil under high application of fertilizer. This agricultural practice resulted in high cost production. A series of researches with the goal to produce high yielding of hybrid corn under low input of fertilizer is going to be a benefit. Field experiment was conducted from April until July 2010 in Manna, South Bengkulu. Single factor consisted of 7 genotipes of corn was set using Randomized Complete Block Design. The seven genotypes were marked as H1, H2, H3, H4, H5, H6 (Prima), and H7 (DK); the last two of which were commercial varieties commonly grown by farmers. The genotypes that showed good adaptation on Ultisol were H1, H2, and H3. These genotypes yielded 5.11 tons ha-1 for H1, 5.56 tons ha-1 for H2, and 5.64 tons ha-1 which were higher than commercial varieties (4.46 tons ha-1 for Prima and 4.62 tons ha-1 for DK). Plant height for H1, H2, and H3 were 1.78 m, 1.80 m, and 1.88 m respectively, while plat height of Prima and DK were 1.45 m and 1.51 m.

Abstract

Rubber plant is an important industrial crop, as for economic community and a source of non-oil foreign exchange for the country.  In Indonesia, 85% rubber planting area is community rubber plantation with its productivity is still very low (700 - 900 kg ha-1 year-1), compared to its potential which can be more than 1,500 kg ha-1 year-1.  The low productivity of community rubber plantation is because of the lack of proper handling and maintenance of their plants.  Efforts is needed to improve the quality and productivity of community rubber plantation so as to compete in international trade by improvement on planting, maintenance, latex post-harvesting from the garden to the final processing stage.  This research utilizes solid waste from rubber processing factory that is local organic fertilizer (LOF) which is usually merely dumped and become source of environment contaminant.  The objective of this study was to determine the optimum dosage of rubber mill waste to the yield of rubber plants.  The research was carried out at farmer?s plantation of Tanjung Tengah village, Sub-district of Pondok Kelapa, Central Bengkulu, from May to August 2016.  The experiment was arranged in a Randomized Complete Block Design (RCBD) with four replications and 6 levels of LOF as the treatments i.e. 0, 10, 20, 30, 40 and 50 kg tree-1 equal to 0, 5, 10, 15, 20 and 25 tons ha-1, respectively.  The results showed that the effect of several doses of organic fertilizer of rubber waste to rubber plants had no effect on latex volume, stem girth, latex weights, latex slab weight, and dry weight.  The yield of rubber even tended to decrease as the increase of dose of LOF.  This was supposedly because the rubber plant is an annual crop so takes a long time to show the response of the treatment.Keywords: rubber sap, waste, compost fertilizer

Abstract

A research was conducted to identify the genetics of upland rice cultivars using random amplified polimorphic DNA (RAPD) markers. Five out of 60 random primers that capable to amplify the most number of markers were OPE-07 (AGATGCAGCC), OPE-15 (ACGCACAACG), OPH-13 (GACGCCACAC), OPH19 (CTGACCAGCC), and OPM-02 (ACAACGCCTC). The number of markers amplified were 5, 6, 8, 8, and 7, respectively. RAPD-PCR using these 5 primers arranged to DNA templates of 41 rice cultivars amplified 1127 RAPD markers. Polymorphic information content (PIC) of each primer were 0.79, 0.80, 0.87, 0.87, and 0.72, respectively. Cluster analysis using a UPGMA dendogram showed that the 41 cultivars were grouped into 9 clusters with genetic similarity index more than 90 percent.
