First report of Begomovirus infection on papaya in Bengkulu, Indonesia. A field survey was conducted during 2019, wefound a severe systemic yellow mosaic, striped green mosaic on leaves petiole, green spots on the fruit of papaya, leafmalformation, and stunting symptoms on three papaya cultivation area in Rejang Lebong, Kepahiang, Bengkulu Tengah, andSeluma, Bengkulu Province, Indonesia. A begomo-like virus was inferred to be the possible cause of the virus-disease-likesymptoms. The study aimed to identify the causal of those typical symptoms on papaya. PCR using universal primer fortranscriptional activator protein (TrAp) and replication-associated protein (Rep) gene of Begomovirus successfully amplifiedthe DNA fragments of 900 bp in all 10 detected samples, except for samples with leaf malformation and stunting symptoms. Itis indicating that those typical symptoms on papaya is associated with Begomovirus infection, while the causal of leafmalformation and stunting is unknown yet. This work is the first report of Begomovirus infected papaya in Indonesia. Severedisease incidence caused by this pathogen was observed on papaya plants in Bengkulu Province that was in the range of 42–100%. This finding is a precious information to be used for identification, and characterization the species of the virus,determining control strategies against the disease.

Kacang tanah merupakan salah satu tanaman pangan penting di Indonesia dan mempunyai peran strategis dalam perekonomian nasional, mengingat fungsinya yang multiguna, sebagai sumber pangan, pakan, dan bahan baku industri. Penelitian ini bertujuan untuk mengetahuai dan mendapatkan dosis pupuk P dan K yang tepat untuk perbaikan tanaman kacang tanah di tanah Ultisol. Penelitian dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Ratu Samban Arga Makmur Kabupaten Bengkulu Utara pada bulan Desember 2018 sampai Maret 2019. Bahan penelitian yang digunakan adalah benih kacang tanah varietas Talam, pupuk organik, pupuk TSP, KCl, Urea dan tanah Ultisol. Penelitian ini dilaksanakan menggunakan Rancangan Acak Kelompok pola faktorial dua faktor. Faktor pertama perlakuan pupuk P berasal dari TSP terdiri atas empat taraf yaitu 3 g tan-1, 4 g tan-1, 5 g tan-1, dan kontrol. Faktor kedua perlakuan pupuk K berasal dari KCl terdiri atas empat taraf yaitu 3 g tan-1, 4 g tan-1, 5 g tan-1, dan kontrol. Hasil penelitian menunjukkan bahwa perlakuan TSP 4 g tan-1 menghasilkan komponen vegetatif dan generatif kacang tanah terbaik. Pada perlakuan kalium tidak terdapat perbedaan yang nyata terhadap semua variabel pengamatan, namun terdapat kecenderungan, perlakuan pupuk KCl 4 g tan-1 menghasilkan komponen generatif yang lebih baik. Tidak terdapat interaksi antara phosfor dan kalium yang nyata terhadap semua variabel pengamatan kacang tanah.   Kata kunci : kacang tanah, phosfor, kalium, Ultisol.

High production of long beans is closely related to the variety used and growing environmental conditions. The selection process to obtain varieties with high yields is caused by the correlation between yield characters and yield components. The purpose of this research was to obtain information about the correlation between the growth and yield characters of long beans through correlation analysis. The research was conducted from July to September at the former rice fields of Muara Bangkahulu district and using local long bean genotypes. The experiment design used was completely randomized block design with three replications. Correlation analysis was performed on the character of leaf length, leaf width, harvesting age, pod length, pod diameter, weight per pod, number of pods per plant and pod weight per plant. The results showed that the leaf width character had a significant positive correlation with the pod diameter character. The characters of pod length, weight per pod and number of pods per plant had a significant positive correlation with the yield characters of pod weight per plant. The characters of pod length, weight per pod and number of pods per plant long bean genotypes can be used as parameters for the criteria selection.

Correlation between growth characters and yield components in peatland]. Utilization of peatlands can increase the production of eggplant (Solanum melongena L.). In addition, it also carries out variety assembly to produce high yielding adaptive varieties on peatlands. The research objective was to see the relationship between growth characters and yield components of eggplant. The research was conducted in Medan Baru, Muara Bangkahulu District, Bengkulu City. The experiment was carried out using a randomized complete block design on one factor with 3 replications. The factor used the Bengkulu local eggplant variety. The results showed that the character of plant height was positive correlation and very significant to the character of dichotomous height and stem diameter. Flowering age was very significant positive correlation with harvest age and significant negative correlation with fruit weight per plant. Harvest age was very significant negative correlation with fruit weight per plant. Weight per fruit was very significant positive correlation with fruit length and fruit weight per plant. Fruit length was negative correlation with maximum fruit diameter and a very significant positive correlation with fruit weight per plant.
