For anticipating future need for physic nut (Jatropha curcas L.) variety with high yield, short growing period demand and tolerant to pest and plant disease, an exploration for collecting new accession to East Nusa Tenggara (NTT), Bali and Gorontalo had been conducted. Beside exploration it has also been developed some accession and improve population from KIJP Pakuwon, Muktiharjo and Asembagus.Population formed in plan furrows and designed in sizes of plots. Accession from the exploration and donor have been planted on August, 2008 in PT Bumimas Ekapersadas plantation in collaboration with Indonesian Center for Estate Crops Research and Development at Pasirranji, Bekasi, West Java. Physical data and collection plant identification result was targeted to obtain variety that has short period to bare fruit, high yield rate and tolerant to pest and plant disease.Based on the examination of morphological growth and development, it can be concluded that Jcur.0006 showed characterstic of short and development in growth and production, accession that has characteristic a short period to bloom and high yield rate with perfect growth is Jcur.0006, plant number 15, and Jcur.0030 with plant number 8, but this variety is less tolerant to louse pest.With assumption that each branch has one bunch, thus 1.600 dry seed weight equals to 1 kg and 2 m x 2 m planting range, first year production potential from each accession originated from Gorontalo Jcur.0006; while plant number 6 and from NTT Jcur.0030 plant number 8, may reach minimum rate not less than 2.25 ton/ha dry seeds and 2.39 ton/ha dry seeds.

Ginger (Zingiber officinale Rose.)and melinjo (Gnetum gnemon L) are potential comodities that have great opportunity to be promoted.Ginger is one of nine spices in international trade (and its market is also available in Indonesia and foreign market),while melinjo is known for long time and has high economic value. One important in promoting both comodities had to be known land potency in which both comodities would be cultivated.Land identification would be base on soil analysis in the laboratory,land ability map and field observation. Evaluation of soil fertility criteria and land suitability based on TOR Classification of land ability from Center Research of Soil and Agroclimate.Evaluation of soil chemical properties include N-toial, P-available, exchangeable potassium, cation exchange capacity, pH, and C-organic content.Evaluation of soil physical properties include soil-texture, drainage, soil effective depth and climate.The aim of this study was to observe real/current and potential land suitability level for ginger and melinjo in Lebak District.The result showed that land potency for promoting ginger and melinjo were 89 ha and 71 - 98 ha respectively.

MODEL-MODEL POTENSIAL TANAM HUTAN RAKYAT DENGAN TANAMAN REMPAH DI KABUPATEN SUKABUMI, PROVINSI JAWA BARAT Effendi, Dedi Soleh; Hoerudin, Hoerudin

Indonesia has great potentila in terms of community forest reaching more than 42 million ha. This potential, however, is still unwellmanaged so that is couldnt be a main source of farmersincome. In fact, according to argo ecology system; community forest can be cultivated by introducing promising intercrops in order to deliver more benefical effect. To overcome this problem, a reseach aiming to obtain potential models for community forest and spice crops intercropping pattern based on agro ecological zone was conducted from Â August to December 2000. The reseach was carried out on 1.000 ha of partnership-based community forest (Paraserianthes falcataria) in Lengkong and Tegalbuled Sub district,sukabumi Regency, West Java province. the objectives of the research were achieved through survey method in gathering primary and secondary data. The data were analyzed by using Expert system Program (version 3.2.2.) and Framework of Land Evaluation. the results showed that the community forest explored was devided into 6 agro ecological zones with 5 recommended-landuses. Those are forestry (Zone I), palntation (Zone IIlax and IIbx), agroforstry (zone IIIax and IIIbx), and upland cultivation (Zone IVax2). According to microlimate condition under P.Falacataria trees, bushy pepper (Piper nigrum) is the most promising intercorps. Meanwhile, framework of land evaluation revealed that Zingiber officinale, Amomum cardamomum, and other Zingiberaceae species were marginally suiltable accompanied by heavy texture as the main constraint. In short, the potential models were (1) P. falactaria + A. cardamomum; (2) P.falactaria + P.nigrum. (3)Â P.falactaria +Â Z.officianale and (4)Â P.falactaria + Zingiberaceae (Curcuma xanthorizza, C.domestica, and Kaemferia galanga). Model (1),(3) and (4) would be more suitable on zone IIIax,IIIbx, and IVax2, whereas model (2) should be on zone IIIax nad IVax2.
