Pepper is widely cultivated as a condiment and cash crop in Indonesia. However, Pepper yellow leaf curl disease (PepYLCD) caused by begomovirus is currently seriously affect the domestic pepper production. Breeding for begomovirus resistance material by crossing is currently necessary to overcome the constraint. The present study is aimed to determine the resistance of pepper (C. annuum) plants F2 progenies to begomovirus infection in the growth stage. Two local C. annuum accessions, BaPep-5 as a resistance donor for pepy-1 begomovirus resistance gene (locally called Perintis) and BaPep-4 as a susceptible parent (locally called Kencana) were crossed to generate F2 progenies. The research was conducted in Agricultural Extension Training Centre (BLPP) Saree and Horticulture Laboratory of Syiah Kuala University from February to July 2020. 500 F2 progenies were transplanted to the field along with 15 plants of each parent as control. The result suggested that plant height and crown width had the highest broad sense heritability value, whereas the dichotomous height, stem diameter, secondary branch, and tertiary branch had the lowest broad sense heritability value. Coefficient of genetic variance and coefficient of phenotypic variance from overall characteristics were relatively low which suggest the narrow sense to slightly narrow sense heritability.
The productivity of pepper plants is strongly influenced by climatic and weather conditions as well as pests and diseases. One of the major losses in chili farming is the pest attack, such as whiteflies (Bemisia tabaci Genn.), a virus vector. Evaluation of the resistance of pepper plant germplasm against Begomovirus infection needs to be carried out, evaluate genetic diversity, estimate heritability values, and obtain a selection character for the resistance of chili plants Begomovirus. This research was conducted at Experimental Garden, Faculty of Agriculture, Universitas Syiah Kuala, and the Laboratory of Genetics and Plant Breeding, Faculty of Agriculture, Universitas Syiah Kuala from January to May 2020. Three varieties Gada, Anies and Selekta with seven test genotypes i.e F6 Gada, Seloka 4-10-2-2, F5136074-1-4-3, F5074136-2-3-2, F5074035-2-1-2, F5074035-2-4-2, F5074077-1-1-3 were screened for their resistance against Begomovirus. This study was designed using a non-factorial Randomized Block Design (RBD) and scoring parameter Begomovirus symptom. Tukey’s HSD, the standard deviation of genetic variance, heritability, and correlation were performed to analyze the data. The lowest disease intensity occurred in genotype F6 Gada with a percentage of 12.08% disease intensity (slightly resistant), and the highest level of disease intensity occurred in F5074035-2-4-2 with a percentage of 30.94% (susceptible). Variables symptom scoring, disease intensity, and incubation period were the most effective variables for selecting pepper resistance against Begomovirus infection based on broad-sense heritability values.
Abstrak. Penelitian pengaruh pemberian pupuk hayati Bioboost terhadap pertumbuhan dan hasil beberapa varietas kacang tanah dilaksanakan di Kebun Percobaan Fakultas Pertanian dan Laboratorium Hortikultura Universitas Syiah Kuala, Banda Aceh yang dimulai pada bulan Agustus sampai dengan Desember 2017. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk hayati dan varietas kacang tanah serta interaksi antara pupuk hayati dan varietas terhadap pertumbuhan dan hasil kacang tanah.Penelitian ini dilakukan dengan menggunakan Rancangan Acak Kelompok (RAK) pola faktorial dengan 2 faktor dan 3 ulangan. Faktor pertama yaitu konsentrasi pupuk hayati Bioboost yang terdiri dari 4 taraf dan faktor kedua yaitu varietas kacang tanah yang terdiri dari 3 taraf. Hasil penelitian menunjukkan bahwa konsentrasi pupuk hayati Bioboost berpengaruh terhadap jumlah polong bernas, berat biji pertanaman dan potensi hasil dengan konsentrasi terbaik yaitu 20 ml/l. Sedangkan untuk varietas berpengaruh terhadap pertumbuhan dan hasil dengan varietas terbaik ialah varietas TubanEffects of Bioboost liquid biofertilizer on growth and yield varieties of peanut (Arachis hypogaea L.)Abstract. The research of Effects Bioboost liquid biofertilizer on growth and yield varieties of peanut has been carried out in experimental garden and laboratorium of horticilture Departement of Agroteknology, Agriculture Faculty, Syiah Kuala University in Banda Aceh was started from August until December 2017. The purpose of this study was to find out about the effect of Bioboost liquid biofertilizer and varieties of peanut and interact between Bioboost liquid biofertilizer with varieties of peanut on growth and yield. The research used group randomized design method consisting of 2 factors and repeated 3 times. The first factos is consentration of Bioboost liquid fertilizer consisting of 4 levels and the second factor is varieties of peanut consisting 3 levels. Results of the research showed consentration of Bioboost liquid biofertilizer was effected on number of pods, plant seed weight and harvest with the best consentration was 20 ml/ l. While for varietiy was effected growth and yield with the best variety was Tuban
The aim of this study is to determine the effect of combine organic fertilizer (manure) and inorganic fertilizer (NPK and Micro fertilizer) on the growth and yield of cucumber (Cucumissativus L.). This study was conducted in the Experimental station, Agriculture Faculty, Universitas Syiah Kuala, Aceh from February to April2018. This experiment was arranged in a factorial randomized completely block design with two factors and three replications. The first factor was the provision of organic fertilizer (manure) with 3 levels: 10 t ha−1(K1), 20 t ha−1 (K2), and 30 t ha−1 (K3). The second factor was the provision of inorganic NPK fertilizer with 3 treatments: Without NPK fertilizer (control - N0), NPK Fertilizer(N 50 kg ha−1 P2O5 50 kg ha−1 and K2O 50 kg ha−1 (280 kg ha−1Phonska 16-16-16 - N1), and NPK + Micro Fertilizer (N 50 kg ha−1 P2O5 50 kg ha−1 and K2O 50 kg ha−1 (280 kg ha−1Phonska 16-16-16 + 2% Micro fertilizer – N2)). Results show that organic fertilizers (20 and 30 ton ha−1) increase fruit weight of each sample and fruit weight of each plant. The application of NPK + Micro Fertilizer produces in the best fruit weight of each sample and fruit weight of each plant. The combination of organic fertilizer (20 ton ha−1) and inorganic NPK + Micro Fertilizer results in the best fruit weight each plant of cucumber.
This study aimed to obtain the homogeny of M8 soybean lines in an effort to release new high yielding varieties. The research was conducted in Lamsidaya village, and the observation of yield components was carried out at the Plant Breeding Laboratory, Faculty of Agriculture, Universitas Syiah Kuala. This study did not use an experimental design, so that the quantitative characters were observed individually from each plant, then analyzed by estimating the heritability broad sense value and the progress of selection. The material used were var. Kipas Putih and var. Dega1 as control, eight of 7th generation Kipas Putih mutant lines (B4, B7, B10, B12, B13, B15, B18 and B22). All genotypes were planted in rectangular plot 10 m x 1 m, drainage 50 cm, and planting distance 50 cm x 30 cm. Plants were maintained in accordance with the recommendation for soybean cultivation from Balitkabi, and fertilizer NPK (16:16:16) was given 200 g/plot (200 kgha-1). Parameters observed included plant height, flowering time, harvest time, number of productive branches, total number of pods per plant, number of filled pods per plant, percentage of filled pods per plant, seed weight per plant, weight of 100 seeds, seed weight per plot, and yield potential. All quantitative characters indicated increase on selection except for the character of plant height, percentage of filled pods and weight of 100 seeds because the heritability value was low. The B18 line has the potential to become a new high yielding variety because it has a high yield potential (3.02 tons ha-1) with a large seed size compared to the other seven mutant lines and is also higher than the parent Kipas Putih and var Dega 1 varieties.
