Abstract

Combining ability is the genotype's ability to pass on the desired character to the offspring.  Combining ability information is needed to determine the crossed pairs in the formation of hybrid varieties.  The purpose of this study was to obtain information on the combining ability value of six S7 generation of inbreed maize.  The experiment was conducted in September 2015 until January 2016, at Medan Baru Experimental Station of Faculty of Agriculture, at Kandang Limun village, Muara Bangkahulu Sub-district, Bengkulu City.  The experiment was prepared in a Randomized Block Design (RCBD) with 15 corn hybrid treatments including: G1XG3, G1XG6, G3XG6, G1XG7, G3XG7, G6XG7, G1XG8, G3XG8, G6XG8, G7XG8, G1XG9, G3XG9, G6XG9, G7XG9 and G8xG9.  Each experimental unit was repeated three times obtaining 45 experimental plots.  Estimation of general combining ability (GCA) value  and specific combining ability (SCA) of each inbreed strain were conducted with Griffing model IV method.  The results showed that genotype G1 and G3 had positive GCA values for all characters except plant height.  The G7XG1 cross combination showed a positive SCA on all characters even higher in plant height and stem diameter. The G8XG6 cross combination showed high SCA values for leaf number characters, weight of husk-less cob, number of seeds per seed-line, weight of grain per ear, and grain yield per plot.Keywords: Hybrid, corn, GCA and SCA

Abstract

Pineapple plants are usually propagated vegetatively by utilizing the base of the fruit (ratoone), stem buds (sucker), fruit buds (slip) and crown (crown). Propagation of plants by utilizing parts of the plant is less effective in meeting the needs because the planting material produced is small and requires a long time. An alternative to the propagation of pineapple to increase the amount of planting material is by tissue culture techniques. This study aims to obtain the best types of complex organic compounds and the right concentration for the growth of pineapple shoots in vitro. The research was conducted in June 2017 until October 2017 at the Laboratory of Agronomy at the Faculty of Agriculture, University of Bengkulu. Complete randomized design with 3 replications was used to allocate 9 treatments of complex organic compounds. The basic media used are the composition of Murashige and Skoog (MS). Treatment consists of 1) Coconut water 100 ml / l, 2) Coconut water 150 ml / l, 3) Coconut water 200 ml / l, 4) Banana porridge 100 gl / l, 5) Banana pulp 150 g / l, 6) Banana slurry 200 g / l, 7) Bean sprout extract 100 g / l, 8) Bean sprout extract 150 g / l, 9) Bean sprout extract 200 g / l. The results showed that at 16 weeks after MS media planting the addition of 100 g / l banana pulp was able to produce the highest plant height with an average of 3.45 cm. MS media with the addition of 200 ml coconut water resulted in the highest shoot height of 1.5 cm and followed by MS with the addition of 100 g / l media of banana pulp with an average of 0.9 cm. MS media with the addition of 100 ml / l of coconut water is suitable for the growth of pineapple roots with the average value of the number of roots and the highest length of roots. MS media with the addition of bean sprout extract with various concentrations is not able to stimulate shoot growth and has a growth response that tends to be slow. Keywords: Pineapple, In Vitro, Complex Organic Compounds.

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

Extending the planting area to a less-fertile soil, such as Ultisols, become inevitable choice to increase the national chili pepper production in Indonesia as this types of soil is the largest part of dry land of Indonesia, about 29.7% or around 51 million ha.  However, efforts to increase its productivity by providing sufficient fertilizers application is most frequently inefficient because in the conventional fertilizer applications, broadcasted fertilizer on the soil bed, are not readily available for the plant as their solubility is limited under the plastic mulch and still in the form of granular until the end of planting season.  Fertigation, therefore, maybe the answer for this problem.  The objective of this study was to determine the best NPK fertigation method on four chili pepper hybrids.  The experiment was conducted in a randomized complete block design with three replication, and the treatments were arranged in a split plot design.  As the main plots were NPK fertigation intensity, i.e. 100%, 75%, 50%, 25% and 0% fertigation with the remnant fertilizers were circularly broadcasted surrounding the plant.  As the subplots were chili pepper hybrids, i.e. ‘Maxima’, H39, H14, and ‘UNIB CHR17’.  The results showed that there was no interaction effect of fertigation intensity indicated that all hybrid genotypes showed similar pattern of responses.  The H39 hybrid had better vegetative growth compared to other hybrids in term of plant height, dichotomous height, stem diameter, number of branches, plant fresh-weight.  Whereas the hybrid cultivar ‘Maxima’ showed the highest yield followed by H14 and cultivar ‘UNIB CHR17’.  The 100% fertigation was the best method of NPK fertilizer application for chili pepper in Ultisols.keywowrd: fertigation, chili pepper, fertilizer application, acidic soil

Abstract

Coastal area of Bengkulu Province is home of many heirloom rice varieties and play an important role in contributing rice production in the province. However, as the climate change proceeds, a progressive sea water inundation has increased soil salinity mainly in low-lying areas and jeopardizing the sustainability of rice production in coastal regions.  The use of salt-tolerant varieties, therefore, would be a sensible solution to alleviate the adverse effect of soil salinity in respect of maintaining the crop production in the coastal areas. The objective of this study was to examine the salinity tolerance of 20 heirloom rice varieties collected from a coastal area of Bengkulu Province.  Prior to the screening process, lethal concentration 90 (LC90) was determined by assaying the seedlings of ‘Kuning Tinggi’ in a series of nutrient solution containing a different concentration of NaCl (0, 2000, 4000, 6000, 8000 and 10000 ppm). Using a regression analysis, LC90 was detected at a concentration of 3910 ppm. The screening was performed by exposing the varieties in the nutrient solution culture containing 4000 ppm NaCl and growing them on the tidal swamp. Under nutrient culture evaluation, the symptom of NaCl toxicity was scored and converted to salinity tolerance index. ‘Humbur’, ‘Kuning Tinggi’ and ‘Padang Bakung’ exhibited medium tolerant, while ‘Beram’, ‘Imperata’ and ‘Kuning’ exhibited very sensitive. Further evaluation of the tidal swamp for vegetative and generative performances signified that ‘Humbur’ and ‘Kuning Tinggi’ had medium tolerant to salinity stress

Abstract

[PATH ANALYSIS OF GROWTH CHARACTERS AND YIELD COMPONENTS WITH THE YIELD OF 15 GENOTYPES OF MAIZE HYBRID].  Determination of traits used as the selection criteria are based on the trait(s) that have a close relationship to the yield.  The aims of this research were to measure the closeness of the relationship between morphological (growth and yield component) traits and crop yield, and to determine the trait that directly or indirectly affected on maize yield.  The research was conducted in Rimbo Kedui’s Village, South Seluma Subdistrict, Seluma District, Bengkulu Province on May 2017 to August 2017.  The experimental design used was a Complete Randomized Block Design (CRBD) in a single factor with 3 replications.  The treatments were 15 maize hybrid genotypes, consisting of CT1, CT2, CT3, CT4, CT5, CT6, CT7, CT8, CT9, CT10, CT11, CT12, CT13, CT14, and CT15.  The data were statistically analyzed by analysis of varians (ANOVA) with P(a=5%).  The qualitative data were analyzed descriptively. The result of correlation analysis revealed that the yield of maize hybrids highly correlated to some growth and yield component factors.  High-yielding maize hybrids were supported by higher ear diameter, plant fresh weight, plant dry weight, plant height, the number of seeds per ear.  Plant dry weight became the variable that has the highest direct effect with positive correlation on the yield.  The second highest rank was the number of seeds per ear with also a positive correlation value.  Yield improvement of maize hybrid, therefore, can be obtained by fostering the plant total biomass and/or by multiplying the number of seeds per ear.

Abstract

[GROWTH ADAPTATION AND PRODUCTIVITY OF 20 CAYENNE PEPPERS (Capsicum annuum L.) GENOTYPES IN LOWLANDS AREA]. The cultivation of chili peppers in lowland areas of Indonesia faces several environmental challenges. Efforts to increase red chili production in lowland regions include planting genotypes that are adaptive to local environmental conditions. This study aims to obtain information on the best red chili genotypes that can adapt and produce well in lowland areas. The research was conducted from May 2024 to September 2024 using the Completely Randomized Block Design (CRBD) method with a single-factor treatment, consisting of 20 genotypes red chili with three replications. The data collected included growth variables (plant height, first dichotomous height, leaf area, number of dichotomous points, stem diameter, and plant dry biomass) and yield variables (first harvest age, number of fruits per plant, fruit diameter, fruit length, fruit weight per plant, and percentage of marketable fruit). The results showed that the ‘Lotanbar’ genotype exhibited the best performance during the vegetative phase, as indicated by the largest total leaf area, the highest number of dichotomous points, the largest stem diameter, and the highest plant dry weight compared to other genotypes. Meanwhile, the ‘Baja F1’ genotype demonstrated superior performance during the generative phase, producing the largest fruit diameter and the highest fruit weight per plant, reaching up to 200% higher than the genotype with the lowest yield. Thus, the ‘Lotanbar’ genotype is recommended for optimization during the vegetative growth phase, while ‘Baja F1’ is more ideal for increasing yield during the generative phase in red chili cultivation in lowland areas.
