Abstract

Area and pepper production in Lampung were decreased from time to time and potential to become extinct if it isn’t immediate treatment seriously. The study were to analyze the effect of internal factors of farming management on pepper productivity in Lampung Province which is expected to provide benefits for preparing pepper development policy in the future. The study was conducted in North Lampung, East Lampung, and Way Kanan regency, from January to December 2014. The study used survey methods and interview with structured questionaire with sample of 180 people which are stratified by: a) farmers who have planted pepper but he is not planting pepper anymore; b) farmers growing pepper with conventional  technology introduction; and c) farmers who plant pepper with recommendations technology package of  IAARD. The results showed that technically of internal pepper farm management factors that affect on pepper production in Lampung is acreage, NPK Phonska, SP36 fertilization, and application of pepper monoculture cropping. Efforts to increase pepper production in Lampung could be achieved through the addition of pepper acreage supported with intensive handling pepper plants through cultivation technology properly such as NPK Phonska fertilization, SP36 fertilization, and the application of pepper monoculture cropping. The development of a relatively good price of pepper last two years should be a momentum for the revival pepper in Lampung. Support technological innovation needs to be improved through the assistance and support on the implementation of SOP accompanied by an increase farmers' access to production inputs especially fertilizer.Keywords: pepper, technical factor, socioeconomic factor, productivityAbstrakLuas area dan produksi lada di Provinsi Lampung terus berkurang dari tahun ke tahun dan terancam punah jika tidak segera dilakukan penanganan secara serius.

Abstract

Pepper is an introduced species and has always been propagated vegetatively, so it has narrow genetic base. High genetic diversity is necessary to produce new varieties, especially for breeding of resistance to foot rot disease. Increasing genetic diversity can be done through gamma ray irradiation. This research aims to evaluate response of black pepper Ciinten variety at seed and radicle emergence phases to gamma ray irradiation. The research was conducted in PAIR BATAN and greenhous e IMACRI from June 2014 to April 2015. The plant material was Ciinten variety at the seed and radicle emergence phases. The experimental design used was completely randomized design (CRD) with one factor which is dose of irradiation with seven levels (0, 25, 50, 75, 100, 125, 150) Gy. Each treatment consisted of three replications, each replication consisted of 60 seeds. Both phases showed significant differences in perfomances between dose in plant height, leaf length, number of leave, number of internode. Radiosensitivity of pepper on radicle emergence phase was higher than the seed phase indicated by LD50 (Lethal Dose 50). LD50 at seed phase was 68.15 Gy, whereas LD50 of the radicle emergence phase was 30 Gy. The higher irradiation dose that given to both treatment phases caused reduction in plant height, leaf length, while the number of leaves and nodes decreasing. Irradiation dose 25 dan 50 Gy in seed phase and 25 Gy in radicle emergence phase significantly increase genetic diversity base on quantitative, qualitative characters, anatomy and leaf resistence to P. capsici infection. Eighteen putative mutants resistant to infection P. capsici. Eighteen mutant putative Ciinten pepper varieties were expected to be high yielding varieties with more research in the greenhouse and in the field to determine the production and quality potential.
