Abstract

The cultivation of sweet corn currently relies on inorganic nutrient inputs, which often lead to excessive use of fertilizers and subsequent land degradation. To address this issue while maintaining land productivity, researchers have explored the application of vermicompost fertilizer, known for its positive impact on soil physical, chemical, and biological properties. The aims of study were to determine the vermicompost fertilizer doses applied at different times to enhance sweet corn growth and yield. The research was arranged in a completely randomized block design with a single factor by combining the doses of vermicompost (50% to 100%) and variations of application times (one to two weeks before planting). Each treatment was replicated three times. The results revealed that the 100% vermicompost applied two weeks before planting showed the highest increased on the plant height, leaf numbers, and the husk cob weight. The application of vermicompost as organic fertilizer on sweet corn cultivation enhanced the productivity of sweet corn.  Keywords: application times, environmental safety, organic farming, sweet corn, vermicompost

Abstract

Goat manure contains high potassium, thus it is expected to reduce  the usage of synthetic potassium fertilizer. Incubation of goat manure is needed prior to planting since the nutrients are slow release. The objective of the experiment was to find the best time application and dose of potassium on growth and yield of melon. Container experiment using polybags was set in Completely Randomized Design.  Goat manure were incorporated into soil at the time of transplanting (0 DBT), 5 days before transplanting (5 DBT), and 10 DBT. The dose of potassium was consisted of 0 kg/ha, 200 kg/ ha and 400 kg/ha. The treatments were repeated 3 times, each of which consisted of 4 plants. Growth and yield of plants showed no response to the interaction between the two factors of treatment. Single effect of time applicaton of goat manure 10 DBT affected leaf area (1619.51 cm2), fruit weight (872 g), fruit diameter (16.19 cm) and the thickness of edible fruit part (2.61 cm). The dose of potassium 400 kg/ha increased fruit sweetness to 8.20Brix.

Abstract

Rice (Oryza sativa L.) is the most important crops commodity in Indonesia because it is the main staple for the people of Indonesia but currently,  in Indonesia, the production of rice is still not maximal so it can not meet the demand of Indonesian people for national food needs. Therefore, it is necessary for rice plants that have high production and tolerant to various stresses. Plant breeding  is one of the ways that can be done to increase the production of rice, one of which is the method of cross-recurring selection. Genetic diversity is a variation of characteristics that are inherited in the same species population. This study aims to obtain information about genetic diversity and agro-morphological characters of 50 genotypes rice derived from the recurrent selection. This research was conducted from August until December 2017 in Rawa Makmur Village, Bengkulu Province with the height of place from sea level ± 2 m. The study used a Completely Randomized Block Design (RAK) with 3 replications. The seeds used were 50 genotypes of rice from previous cross-selection results from Bugis/N-22 crossbreeds, Bugis/IR-7858-1, Sriwijaya/N-148, Sriwijaya/IR-7858-1. The results showed that the genetic diversity of rice is quite narrow to moderate, but there are some rice characters that have medium to high heritability value that was plant height, harvesting age, flowering age, the total number of tillers and panicle length, so that character can be used for the next generation rice selection. The genotypes produced by Bugis/IR-7858-1 crosses have panicle length, filled grain per panicle, and high grain weight/hill resulting in high yield potential.

Abstract

A common problem related to the production of potatoes in Indonesia is the use of poor quality seed sources and declining seeds. Plant tissue culture is one of the best methods used for the provision of quality seeds. This study aims to establish the best combination of BAP concentration and the concentration of paclobutrazol in spurring the growth of cuttings and initiation of potato tubers in vitro.This research was conducted in November 2017 until June 2018 at Agronomy Laboratory of Biotechnology Division and Plant Culture Network of Agriculture Faculty of Bengkulu University. The  research  design  used  was  Completely  Randomized  Design  (CRD)  which  consist  of  18 combination of BAP treatment and Paclobutrazol was repeated 6 times. The concentration of BAP used was 0 mg / l, 5 mg / l, 10 mg / l and the concentration of Paclobutrazol 0 mg / l; 2.5 mg / l; 5 mg / l; 7.5 mg / l; 10 mg / l; 12.5 mg / l. The data of the research were analyzed by F test of 5% level and if there were different between treatments followed by Duncan's Multiple Range Test (DMRT) test of5% level. The results showed that the combination of BAP and  Paclobutrazol concentration had significant effect on all observed variables. Treatment of 5 mg / l BAP and 7.5 mg / l Paclobutrazol is the best medium in inducing potato micro tube as indicated by the fastest tuber formation time, highest percentage of productive crops, largest number of tubers per bottle, number of tubers per productive plant, tuber diameter the largest and highest wet weight of tuber per bottle. Keywords : in vitro, BAP, paclobutrazol, Potato

Abstract

Bengkulu Province has many local rice germplasms that have adapted to specific areas. The germplasm has certain character advantages so that it is maintained by farmers. The characteristics of each germplasm need to be identified in order to improve the properties of the existing germplasm. This study aimed to determine the performance, to estimate the value of genetic parameters, and to determine the genetic relationship of local rice genotypes collected from four districts in Bengkulu Province. The results showed that the ‘Kuning Sulaowangi’ genotype was the earliest in maturity had the highest number of tillers amongst genotypes. Genotypes which have significantly the highest average component yields were ‘Kunig Air Dingin’ and ‘Impera’.  Traits that have a high heritability estimated value were weight of 100 grains (91.046%) and grain weight per panicle (80.252%). The weight of 100 grains also has the highest genetic variability value. Thus increasing local rice production is possible. Based on the results of the analysis with the similarity coefficient of 55%, the local rice genotypes could be grouped into two groups.  Group I consisted of 9 genotypes namely ‘Kuning Pendek’, ‘Humbur’, ‘Cantik’, ‘Pandak Kelabu’, ‘Cisadane Putih’, ‘Kuning Sulaowangi’, ‘China Abang’, ‘China Putih’ and ‘Impera’. Other genotypes were in Group II.  Trait improvement can be done through hybridization between individuals of different groups. To develope early in maturity and high-yielding varieties can be done through hybridization of the ‘Kunig Sulaowangi’ and ‘Kunig Air Dingin’
