Abstract

Biological agents Trichoderma virens and T. amazonicum have been developed and examined for their effectiveness through in vitro and in vivo approaches against Rigidoporus microporus, the cause of white root disease (WRD) in rubber. The effectiveness of these bio-agents can be determined by testing the dosage and frequency of Trichoderma spp. biofungicide application. The research aimed to investigate the effective dose and application frequency of Trichoderma spp. biofungicide on R. microporus infection in rubber seedling. The experiment was conducted in laboratory and screen house of Indonesian Industrial and Beverage Crops Research Institute (IIBCRI), Sukabumi, from June to December 2014. A randomized block design was used with 14 treatments and 3 replications, i.e biofungicide combination (T. virens and T. amazonicum), dosage (25, 50, and 75 g), application frequencies (1 and 2 times application), and two controls (positive and negative). Rubber seedlings used were propellegitiem seeds of GT1 clone planted in polybags. Trichoderma spp. was multiplied using fermentation method in liquid medium, whereas biofungicide was formulated using talc as carrier. Observed variables including Trichoderma spp. population number, incubation period, attack intensity, and WRD attack suppression. The results showed that T. virens and T. amazonicum biofungicides with 50 g/plant dose at one application was the most effective and efficient in suppressing R. microporus development on rubber seedlings. The type, dosage, and frequencies of application increased Trichoderma spp. population in soil, prolonged the pathogen’s incubation period, decreased WRD attack intensity, and suppress the attack of WRD disease.

Abstract

Rust disease caused by fungus Hemileia vastatrix is a major disease of Arabica coffee, which reduces yield by 20%–70%. Botanical fungicide is a potential alternative because environmentally friendly and safe to humans health. The research aimed to analyze the effect of oils and extracts of fungicidal plants on uredospore germination and attack intensity of H. vastatrix. The research was conducted in laboratory and greenhouse of Indonesian Industrial and Beverages Crops Research Institute (IIBCRI), Sukabumi, from January to December 2016. The plant oils were of cloves, citronella, Reutealis trisperma, and neem, while the plant extracts used were mahogany, Ageratum conyzoides, and wood vinegar. Those oils and extracts were assessed on uredospores germination of H. vastatrix, both in vitro and on coffee seedlings in the greenhouse. A complete randomized block design was used with 9 treatments and 5 replications. The oils and extracts at 5% concentration were applied on coffee leaves of 6 months old plants then inoculated with H. vastratrix uredospora simultaneously. Attack symptoms, incubation period, attack percentage and intensity were observed. The results showed that plant oils and extracts used in present study effectively reduced the uredospora germination of H. vastatrix. However, oils of neem and R. trisperma as well as A. conizoides extract are more potential to suppress H. vastatrix infection in coffee leaves in greenhouse and reduced attack intensity from 22.2% to 3.6%; 5.2%; and 7.6% with inhibitory level at 83.8%; 76.6%; and 65.8%, respectively. Therefore, they are considered as potential biocontrols for rust disease.

Abstract

Kekurangan unsur seng (Zn) pada tanaman teh [Camellia sinensis (L.) O. Kuntze] dapat menghambat pertumbuhan dan menurunkan produksi pucuk. Penambahan unsur Zn untuk mengatasi dampak kekahatan Zn pada umumnya diberikan melalui daun, berupa pupuk seng sulfat (Zn-22,75%) dalam bentuk garam oksida. Saat ini telah didapatkan pupuk mikro dengan kandungan seng yang lebih tinggi (Zn-30%). Tujuan penelitian adalah mengetahui pengaruh dosis dan interval pemberian pupuk mikro Zn-30% melalui daun terhadap produksi dan komponen hasil pucuk tanaman teh. Penelitian dilaksanakan di Kebun Pasirmalang Afdeling Wetan Blok Pakurendeng II, PT Perkebunan Nusantara VIII, Pangalengan, Kabupaten Bandung, Jawa Barat, dengan ketinggian tempat ±1.600 m di atas permukaan laut (dpl), mulai bulan November 2016 sampai Juni 2017. Tanaman teh yang diamati adalah klon GMB 7 yang telah produktif. Percobaan menggunakan rancangan acak kelompok (RAK) faktorial dengan 2 faktor dan 4 ulangan. Faktor pertama adalah: (1) pupuk Zn-30% dosis 300 g/ha, (2) pupuk Zn-30% dosis 250 g/ha, (3) pupuk Zn-30% dosis 200 g/ha, dan (4) pupuk ZnSO4 dosis 2 kg/ha. Faktor kedua adalah interval pemupukan, yaitu: (1) 1 kali dan (2) 2 kali aplikasi setelah pemetikan. Pengamatan dilakukan terhadap produksi pucuk dan komponen hasil teh. Hasil penelitian menunjukkan aplikasi pupuk mikro Zn-30% sebanyak 300 g/ha dengan interval 1 kali setelah pemetikan menghasilkan pucuk lebih tinggi daripada dosis 250 dan 200 g/ha, tetapi tidak berbeda nyata dengan aplikasi pupuk ZnSO4 pada interval 2 kali aplikasi. Aplikasi pupuk Zn, baik dalam bentuk garam oksida maupun seng sulfat, dapat meningkatkan persentase pucuk peko dan mengurangi jumlah pucuk burung.

Abstract

Farmyard manure and biofertilizer is able to substitute chemical fertilizers in improving the plants growth and production. The manure acts as the  energy source for soil microbes, while biofertilizer with phosphate solubilizing microbes (PSM) can increase phosphate (P) availability for plants.  The research aimed to investigate the effect of farmyard manure added with PSM on growth and yield of 5 Robusta coffee clones, conducted at Pakuwon Experimental Station, Indonesian Industrial and Beverage Crops Research Institute (IIBCRI), Sukabumi, from January 2014 to June 2017. A split plot design was used with 3 replications. The main plot factors were 5 Robusta coffee clones (BP 308, SA 237, BP 42, BP 358, and BGN 371), whereas the subplot  factors were types of fertilizers (chicken, sheep, and cow manure added with PMS), and NPK fertilizers as control. Variables observed were components of vegetative growth, percentage of flowering plants, and weight of fresh berries. The results showed that 5 Robusta coffee clones used exhibited similar responses to the PMS-added farmyard manure application. Chicken manure added with PMS enhanced P-available and improved vegetative growth of coffee plants better than other farmyard manure, similar with the effect of NPK fertilizers. Up to 4 years old plants, the PM-added farmyard manure application did not affect the weight of fresh berries.

Abstract

Knowing the genetic diversity in the tea germplasms collection is one of important conditions for assembling new superior varieties. Information of genetic diversity can be obtained through analysis using RAPD molecular markers. The study aimed to determine the genetic diversity of 21 tea genotypes based on RAPD markers. The research was conducted in Integrated Laboratory, Seameo Biotrop, Bogor, from July to September 2013. Genomic DNA was isolated from 21 tea genotypes leaf samples, then amplified with primer OPA 03, OPA 05, OPB 04, OPB 06, OPC 06, and OPD 08. Electrophoresis result was converted into binary data. The genetic similarity and cluster analysis calculation was done using NTSYS-pc version 2.10. In this research, 50 polymorphic bands (94,34%) and 3 monomorphic band (5,66%) were obtained. Cluster analysis based on Nei's genetic distance using the unweighted pair-group method with arithmatic (UPGMA) divided 21 tea genotypes into two groups at a genetic similarity value of 0,48. Group 1 consisted of 20 tea genotypes, while the second group comprised only a one genotype (Sin 27). The range of genetic similarity matrix was between 28%–92%, the lowest genetic similarity (28%) was found between GMB 4 and Sin 27 genotypes, while the highest (92%) was found between AS 2 and AS 1 genotypes. The information obtained can be utilized in breeding programs with the support of agronomic characters as well as in the conservation of tea germplasm.
