Abstract

ABSTRACTRice (Oryza sativa L.) is a rice-producing crop that is the main food source for most of Indonesia's population. Although rice production increases but needs to be maintained. One of the efforts in maintaining rice production is by assembling superior paddy varieties that are adaptive to Ultisol soil. This study aims to compare the appearance of 15 lines of upland rice grown in Ultisol soil and choose the best lines based on index selection. The research was conducted on August 2015 until January 2016 at New Field Experiment Garden of Agriculture Faculty of Bengkulu University of Kandang Limun Sub-District, Muara Bangkahulu Sub-district, Bengkulu City. The experimental design was Randomized Block Design (RAKL) with 3 replications. As the treatment is 15 lines of rice are G1, G2, G3, G5, G8, G13, G16, G24, G30, G32, G35, G40, G44, G45, and G50. Of the 15 gogo rice strains tested showed that the generative and vegetative variables did not significantly affect the number of leaves, the number of productive tillers, the number of pithy grains per panicle, the weight of the grain per panicle, the weight of 100 grains, and the weight of grain per hill.keywords: upland rice, Ultisol, yield

Abstract

ABSTRACTGoat manure is one of organic fertilizers used as the main input in organic farming practice in Indonesia.  Since the slower availability of  nutrient elements to the plants is the characteristic of this manure compared to the other manures, then research on the time of incubation needs to be evaluated.  The study was conducted  in Medan Baru Fields Experiment, district Muara Bangkahulu Bengkulu city. Randomized Complete Block Design was arranged for the experiment. Time incubation of goat manure in the field was single factor consisted of  no incubation, 1 week before planting, 2 weeks before planting, 3 weeks before planting, and 4 weeks before planting.  As much as 20 tons/ha  of  goat manure was incorporated in the field, no additional inorganic fertilizer was applied on sweet corn plants var. Bonanza F1.  The sweetcorn plants responded better growth to treatment 4 weeks incubation of goat manure compared to treatment of no incubation. Yet incubation time of goat manure showed no  significant effects on sweet corn yieldKeywords: incubation,goat manure, sweet corn, growth, yield

Abstract

Success in a breeding program is primarily determined by the availability of information about the genetic diversity of the genetic material used and the expected heritability of the character to be improved. The objective of this study was to determine genetic diversity and heritability of growth and yield components of 10 curly chili genotypes. This research was conducted in September 2015 - February 2016 in the Medan Baru field experiment of Faculty of Agriculture at Kandang Limun Village, Muara Bangkahulu Subdistrict, Bengkulu City. The experiment was arranged in Completely Randomized Design (CRD) with ten genotypes and six replications. The genotypes used were Local Payakumbuh, Ferosa, Laris, Kopay, Romario, Keriting Hitam, Local Curup, Bogota, Sempurna and Mario. The results showed that genetic diversity of the ten varieties was narrow based on plant height variables, dichotomous height, stem diameter, flowering age, harvest age, fruit length, fruit diameter, weight per fruit and number of fruits.  Stem diameter, fruit length, fruit diameter and weight per fruit had moderate heritability estimates; meanwhile, anthesis and number of fruits showed low heritability.

Abstract

Bambara groundnut (Bogor groundnut) was an alternative food crops having high nourishing, better taste and bigger size nut than the soy beans and peanuts. To meet the need for food and industrial needs, the program to increase production of Bogor groundnut was required, one of which is the use of peat as a growing medium using the technology of mixing peat and mineral soil. The research objective was to obtain a mixture of peat with mineral soil and dolomite lime dose suitable for the highest growth and yield of Bogor groundnut.  This study was conducted in May 2015-September 2015 in the Greenhouses of Faculty of Agriculture, University of Bengkulu. The experiment was arranged in a completely randomized design (CRD) with two treatment factors and three replications. The first factor was soil mix of peat and mineral soil (G0: 100% peat + 0% mineral soil; G1: 75% peat + 25% mineral soil; G2: 50% peat + 50% mineral soil; G3: 25% peat + 75% mineral soil) and the second factor was the dose of dolomite (D0: without lime dolomite; D1: 3 ton ha-1 and D2: 4 ton ha-1). The results showed that the response of biomass dry-weight to a mixture of peat with mineral soil was influenced by the dose of dolomite, but there was no interaction on other variables.  Treatment of a mixture of peat 100% alone was capable of generating the highest number of leaf, biomass fresh- and dry-weight.  Bogor groundnut plants showed the same response to the dose variation of dolomite lime.Keywords: Bogor groundnut, peat, mineral, dolomite

Abstract

Oil Palm has a strategic role in the Indonesian economy. The use of anorganic fertilizers in the cultivation of Oil Palm is to add nutrients to optimize the growth and yield of plants. The use of anorganic fertilizers significantly  increase crop production, but the use of anorganic fertilizers in a relatively long time period has  negative impact on soil conditions. The use of organic fertilizers can be an alternative in reducing the negative impact of the use of anorganic fertilizers. Compost of empty fruit bunch (EFB) of oil palm has the potential to substitute most of the nutrients needed by plants. This study aimed to determine the effect of local organic fertilizers on yields of oil palm. The research was implemented from January 2016 until March 2016, in the oil palm plantation area of PT Bio Nusantara Bengkulu, Village of Pondok Kelapa, Central Bengkulu Regency, Bengkulu.  Dose of EFB was as treatment in this study, consisted of  control,  4 kg EFB /plant, 8 kg /plant,  12 kg /plant, 16 kg /plant. The treatment was repeated three times with 10 plants per treatment unit in order to obtain 150 samples. The results showed that the dose 21.03 kg EFB can improve the greenish of leaves with the result of 78.65. Dose of EFB 15.38 kg/plant was able to increase the weight of loose/detached fruit to 12.22 grams. The  10.5 kg mesocarp thickness reached 0.96 cm when the plant was treated with EFB 10.5 kg/plant.Keywords: compost, empty fruit bunch, oil palm, organic fertilizer, yield
