Oil palm (ElaeisguineensisJacq) is a plantation which plays an important role for Indonesia as the leading commodity for export or for the commodity that is expected to increase farmers' income. Of the various factors that cause the production of palm oil decreased by one of them is the problem of drought during the dry season as it is known that palm oil has a shallow root system (root fibers) so that the easy availability of water shortages. This research was carried out experimentally by using Completely Randomized Design (CRD) consisting of4 treatments with 3 replications, so there are 12 experimental units. Each unit consists of two plants were taken 1 (one) of plant samples. The tested combined treatment consisting of four levels: A (The Water 2400 ml Marihat D × P), B (Giving Water 2400 Topaz ml D × P), C (Provision of Water 1200 ml Marihat D × P), and D (Provision of Water 1200 ml of D × P Topaz). The parameters observed were plant height increment, number of leaves, corm girth increment, dry weight, seed quality index and proline content. The data obtained were analyzed using ANOVA and followed by further tests DNMRT at level 5%. Result showes that treatment of water supply volume provides significant results on the observation parameters plant height increment, whereas the parameters observed in the number of leaves, corm girth increment, dry weight, and seed quality index showed no significant results after further testing DNMRT at 5% level Key words : water supply, corm girth, drought.

The potato cultivation in the highland area has been redistricted due to the facts of small area that suitable for potato cropping. The suitable landispurposed to be conservation practice. Therefore, inorder to increase potato yield could be established by the expansion to the lowlands area. But in the lowlands has been redistricted by the negative effects of high temperatures for tuber formation and the lack of well adapted variety. Those limitations could be overcome by finding the well variety that could be adapted in the lowland. The experiment aim is to observe the adapted cultivars. The treatments arecultivars: Granola I (G2), DTO 28, Atlantik andtwo varieties, Granola II (G3) and Eigenheimer (highed land at Jambi Provincial). The parameter to evaluate is number of tubers, tuber growth rate, sinc strength and source strength. This experiment used Randomized Block Design (RBD). The results shows that the highest source strength, sinc strength, tuber weight per plant, numbers of tubers, and tuber growth rate was achieved at variety Granola II. Key words: sinc, source, tuber formation.

This research was aimed to evaluated the interaction effect of plant spacing on the growth and yield of six lowland paddy variety based on cuantitative characters.This research was conducted at Jembatan Mas. Pemayung District. Jambi Province. This research was arrangement on Split plot Design with Randomized block design (CRBD). The first factor as main plot : spacing J1 (30x20 cm), J2 (30x15 cm), J3 (30x10 cm), the second factor variety as subplot : V1 ( IR-42), V2 (Cisokan), V3 (IR-64), V4 (Batanghari), V5 (Wayrarem), V6 (Limboto). The Results showed that there were no interaction effect between spacing and paddy variety. There are significantly simple effect of spacing to number of tillers and time of flowering. Simple effect of Variety,have sfignificantly effect of variety to all growth and yield component. The highest paddy yield was achieved at Variety IR 42 ( 4.55 ton ha-1). Key words : genetic variation, quantitative characters.

Anthracnose caused by Colletotrichum acutatum is one of devastated disease of pepper in Indonesia and has great impact on yield loss. Most of farmers use fungicides as controller for this disease. Application of biocontrol agents could be solution to control anthracnose. Beneficial microorganism, such as endophytic fungi are able to be promising biocontrol agents of some pathogens, including Colletotrichum acutatum. The aim of this research was to isolate endophytic fungi from fruit and branch as biocontrol agents for pepper anthracnose. The research resulted 11 isolates of endophytic fungi that were further tested against anthracnose. Isolates of endophytic fungi were identified as steril hifa hitam 1, steril hifa hitam 2, steril hifa 1, steril hifa 2, Nigrospora sp., Coniotyrium sp., Cylindrocarpon sp., Paecilomyces sp. The 3 of other isolates (isolat buah 5, isolat buah 1dan isolat batang 24) were not identified yet. Keyword : Pepper, antrachnose, C. acutatum, endophytic fungi

The objective pf this research was to determine the phenology of vegetative and generative growth of duku plant variety kumpeh at different ages. The treatment was design in randomized block design (RBD) with duku plant age duku as a treatment. The treatments tested were analysis : LA=Age plants less than 25 years; plants LB=Age 25-50 years, and LC=Age 50 years and older plants. On the obtained results, that theair temperature has a positive correlation to the length of shoots, shoots diameter and number of leaves at different plant age duku. Poster for the end of all plant life duku happened in September but there is a difference between the starting time and peak Poster. Flowering in plants duku occurredin the village of Karang Cityin early Octoberis the end of the dry season or the beginning of the rainy season. Duku fruit that reaches fruit set can beharvestedat 125 days after anthesis. Duku plants aged >50 produce fruit that tastes sweeter, with asugarcontent of 18.93% and 0.36% acid levels. Key words :Anthesis, Lansium domesticum, trubus
