Abstract

SSR marker has some merits such as quickness, simplicity, rich polymorphism and stability, thus being widely applied in genetic diversity analysis, molecular map construction and gene mapping. the purpose of this study was to determine polymorpic test and heterozygosity in F4 soybean (Glycine max (L.) Merril) progeni saline resistant characters using SSR (Simple Sequence Repeats) markers. This research was conducted in Biomolecular Laboratory, Socfindo Seed Production Laboratory (SSPL), Kebun Bangun Bandar Village Martebing District Dolok Masihul Regency Serdang Bedagai on December-May 2017. The number of samples were used 44. The five SSR primers (QS080465, QS1101, QS1112, QS100011, and Sat_091) used were specific primers, with a band pattern that was clearly visible around one or two bands. The percentage of polymorphic primers (PLP) of these three populations is high, all populations with a PLP of 100% of the saline resistant character. The effective allele number (Ne) of  7,160 for the progeny population is lower than the number of observed alleles (Na) of 10,000 which means that many progeny individuals are homozygous. The expected heterozygosity (He) value of 0.854 in the progeny population was higher than the observed heterozygosity (Ho) value of 0.027. The overall average observed heterozygosity (Ho) was 0.009 lower than the overall expected heterozygosity (He) of 0.61. This means that each character has a low heterozygosity.Keywords: Progeny F4, soybean, SSR, saline resistant, polymorphic, heterozygosity

Abstract

Utilization of mulch could reduce competition between weeds and soybean crop for water, light, nutrient, maintaining temperature and humidity of soil to create better growth of soybean environment. Soybean crop had a critical period of weeds competition so that siam weed organic mulch should be applied to control weeds at certain time. The research aims to improve the yield of soybean crop that is influenced by application times of siam weed mulch. This study had defferent time of mulch aplications treatment such as at the time of planting, 7 days after planting (DAP), and 14 DAP. The results of this reserch showed that application times had not effected significantly at all parameter. The result also showed the earlier application time of siam weed organic mulch it was on planting time had decreased weed growth then increased yield of soybean. Keywords: Weed, soybeans, mulch, application time

Abstract

Aceh Province has many local varieties that are still cultivated by farmers, especially in the South-West Region of Aceh, the local rice needs to be identified and used as a source of genes in the assembly of new improved varieties to support food security and sustainable agriculture. Bacterial leaf blight (HDB) is one of the limiting factors in rice production. HDB disease is caused by Xanthomonas oryzae pv. oryzae (Xoo), which can reduce rice yield by 30-40%. However, the potential of these varieties as sources of resistance genes against HDB has not been evaluated. This study aims to determine and obtain the potential genotypes of local rice in the West-South Region of Aceh that are resistant to Bacterial Leaves Disease. The research was carried out at the Experimental Garden of the Faculty of Agriculture, Teuku Umar University, Meulaboh, West Aceh from January to completion. The research was carried out starting from the treatment and seeding, preparation of planting media, planting, observation variables: Plant height and number of tillers per age 60 HST, incubation period and length of the observed lesio: 21 HSI: Test results of potential local rice resistance in the West- South Aceh obtained 9 genotypes that are resistant to bacterial leaf blight. The genotypes are used as genetic sources for assembling new high yielding varieties Keywords : Bacterial, Bacterial leaf blight, rice of local varieties,

Abstract

Rice ear bug is a pest which potentially sucks the ripe rice grains, therefore the grain will not be fulfilled or even empty. The usage of organic attractant with the enrichment of chemical pesticide is one of the alternatives to control the rice ear bug.The purposes of this research are to discover the preference of rice ear bug toward the organic attractant and to determine the most effective organic attractant that able to control the rice ear bug in laboratory.The research had been conducted on December 2018 until January 2019, located in experimental garden and research, faculty of Agriculture, Fisheries and Biology, University of Bangka Belitung.This research used experimental method by treating the salted fish attractant, crab, and shrimp.Data was analyzed using Kruskal-Wallis test, descriptive quantitative, and qualitative data will be shown in score and picture.The number and mortality index of rice ear bug on salted fish attractant shows the highest, but not significant different with the shrimp attractant.The number of rice ear bug respectively on salted fish, crab, and shrimp are nineteen, four, and thirteen individuals. Keywords : Rice ear bug,Organic Attractant, Preference

Abstract

Soybeans are staple food after rice and corn. Deterioration of soybeans seed during storage caused by soybeans composed of high lipid.  This study was conducted to investigate the effectivity of priming with various concentration turmeric extract on reduce deterioration soybeans seed during storage. The experiment was arranged in non factorial Complete Randomized Design (CRD) with four levels of turmeric extract concentration treatment, (control, 25%, 50% and 75%.).  The ageing process accelerated by subjecting the seeds to high temperature and relative humidity in a chamber (Deluche methods). Germination and vigour were evaluated periodically. The result showed that priming with turmeric extract could increase vigour and germination under ageing conditions. The 25% concentration  extract showed the  higher value of seed vigour than other concentration. Keywords : Soybeans, priming, turmeric extract, storage period.
