Abstract

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 gacor777 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.  เว็บสล็อต 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

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’

Abstract

Bioherbicides that utilize the allelopathic properties of sorghum plants that experience drought stress are fundamental to sustainable agriculture. This study aimed to look at the efficacy characteristics and flavonoid levels of Suri 4 extracts that have experienced various levels of drought stress. Extract materials were prepared from May to July 2024 at Bengkulu University Greenhouse, Kandang Limun, Bengkulu City, and bioassay tests were conducted in August 2024. Flavonoid analysis was performed at the Integrated Research and Testing Laboratory (LPPT) of Gadjah Mada University in August 2024. This research used a completely randomized design with one factor. One sorghum variety, Suri 4, was planted with water stress treatment through watering patterns every day, every 2 days, every 3 days, every 4 days, and every 5. The bioassay experimental unit was a petri dish, and the experiment was repeated four times. Each petri dish was given 10 mL of water extract, and 25 mung bean seeds were planted and incubated for three days. The results showed that the highest flavonoid levels were achieved by the 5-day watering pattern (3841.65 µg/g), and the lowest flavonoid levels were completed by the daily watering pattern (2948.07 µg/g). The highest germination inhibition was due to the sorghum water extract from the 4-day and 5-day watering patterns and was the best bioherbicide pioneer

Abstract

Soybean is one of the nutritious food commodities and a source of vegetable protein whose production is still below Indonesia's domestic needs. Research needs to be done to increase soybean productivity on marginal land. This study aims to measure the growth and yield of soybeans against the application of ameliorant and organic fertilizer made from palm oil waste. The study was conducted in Gunung Alam Village from February to April 2020. The study used a randomized block design which was arranged in a factorial manner and consisted of two factors with three replications. The first factor was ameliorant, namely 0 ton.ha-1, 1 ton.ha-1, 2 ton.ha-1, and 3 ton.ha-1. The second factor is LPMKS (Palm Oil Mill Fertilizer) fertilizer, namely 0 ton.ha-1, 2 ton.ha-1, 4 ton.ha-1, and 6 ton.ha-1. The results showed that the interaction between amelioran and organic fertilizer had a significant effect on the number of leaves 49 days after planting, namely the dose of ameliorant was 2 tons.ha-1 with LPMKS fertilizer 2 tons.ha-1, which was 29.73 strands. The ameliorant treatment had an effect on the variable weight of pods per plant, and the LPMKS treatment had a significant effect on the variable age of harvest at a dose of 6 ton.ha-1, the number of pods per plant at a dose of 6 ton.ha-1, and the number of pithy pods at a dose of 6 ton.ha. -1.

Abstract

[GROWTH AND YIELDS OF SORGHUM VARIETIES TREATED WITH VARIOUS DOSES OF NPK FERTILIZER IN COASTAL LAND]. Sorghum has a potential to be developed in marginal land in coastal area. Drought stress and low availability of utrients in the coastal area are the main problems in growing sorghum.  Introducing the drought tolerance variety is one solution to overcome the drought stress in coastal land in order to improve sorghum yields. In addition, the treatment of NPK fertilizer is needed to fulfill the nutrients requirements for growth and yields. This research aims to determine the best sorghum variety and an appropriate dose of NPK fertilizer for the growing sorghum in coastal land. Field experiment was conducted at the coastal area in Bengkulu City from August until November 2021. The experiment was arranged in Randomized Completely Blok Design with two factors. That were sorghum varieties (Numbu, Super 2 and Kawali) and NPK fertilizer doses (150 kg/ha, 300 kg/ha and 450 kg/ha). The results showed that the interaction between sorghum variety and NPK fertilizer dose were not significant on the growth and sorghum yields. Numbu varieties produced the highest panicle weight per plant of 69.42 gram. The research concluded that Numbu variety showed the best growth and yields compare two other varieties. The  maximum growth and yield  of sorghum in coastal land were observed at NPK 450 kg/ha dose.

Abstract

This research was conducted from July to November 2020 in the coastal lands of Ratu Agung District, Lempuing Village, Kuala Alam, Bengkulu City, at an elevation of 5 meters above sea level. The study aimed to investigate the interaction between vermicompost and single phosphorus (P) fertilizer on the growth and yield of Detam 4 soybean plants in coastal lands, focusing on determining the optimal doses for both inputs. The experiment was designed as a two-factor study using a factorial Randomized Complete Block Design (RCBD) with three replications. The first factor was vermicompost application at four levels: 0 tons ha-1, 5 tons ha-1, 10 tons ha-1, and 15 tons ha-1. The second factor was phosphorus application at three levels: 0 kg ha-1, 50 kg ha-1, and 100 kg ha-1. Observed variables included plant height, number of leaves, flowering age, number of productive branches, number of pods per plant, pod weight per plant, pod weight per plot, seed weight, and root weight. Data were analyzed using ANOVA at the 5% significance level, with a subsequent 5% LSD test if significant effects were found. The application of vermicompost at a dose of 10 tons ha-1 without the addition of single P fertilizer results in the best growth of the soybean variety Detam 4, characterized by the highest average shoot dry weight of 41.133 g, the fastest flowering age, and the greatest number of productive branches. The best yield of the Detam 4 soybean variety is achieved with the application of vermicompost at a dose of 15 tons ha-1, indicated by the highest number of productive branches and seed weight per plant. The independent application of single P fertilizer does not significantly enhance the growth and yield of the Detam 4 soybean variety in coastal land conditions.

Abstract

Purpose: to determine the total flavonoid content and seed germination characteristics in bioassay tests due to sorghum extracts' application at various drought stress levels. Extract materials were prepared from June to August 2024 at Bengkulu University Greenhouse, Kandang Limun Village, Bengkulu City, and bioassay tests were conducted in August 2024 at Pematang Gubernur, Muara Bangkahulu, Bengkulu City. Flavonoid analysis was performed at the Integrated Research and Testing Laboratory (LPPT) of Gadjah Mada University in August 2024. Methodology: This study used a completely randomized design (CRD) with one factor. Two sorghum varieties, Super 2 and Mandau, were planted with water stress treatment through watering patterns every day, every 3 days, and every 5 days. The experimental unit was a petri dish, and the experiment was repeated four times. The Petri dish bioassay method was applied in this experiment.Each petri dish was given 10 mL of water extract, and 25 mung bean seeds were planted and incubated for three days. Results: The results showed that the Mandau variety had the highest total flavonoid content with watering every 3 days (3991.34 µg/g), and the Super 2 variety had the lowest total flavonoid content with watering every day (3165.26 µg/g). The highest germination inhibition was achieved by the sorghum variety Mandau with watering every 5 days. The treatment produced the highest inhibition on the test plants, so it has the potential to be the best bioherbicide. Findings: The Mandau variety has the highest total flavonoid content with watering every 3 days, and the Super 2 variety has the lowest total flavonoid content with watering every day. Novelty: This study provides insight into the total flavonoid content and seed germination characteristics due to the application of sorghum extracts at various levels of drought stress.
