The importance of kaffir lime leaf as essential oils (EOs) raw material is starting to get attention because of its commercial value; however, there is no quality reference for kaffir lime leaf EOs, especially in response to various post-harvest handlings. This study aimed to describe the physicochemical characteristics and yield of kaffir lime EOs subjected to different post-harvest. Bogor originated-kaffir lime leaf was prepared to be subjected to several post-harvest treatments, i.e., control/fresh green leaves (P1); milling to produce green leaf flour (P2); drying to produce dry brown leaf (P3), and milling and drying to produce brown leaf flour (P4). The result showed that post-harvest treatment generally decreases an oil yield and increases darkness color, specific gravity and refractive index of tested EOs. Additionally, post-harvest treatment also changes metabolite profile revealed by GCMS analysis. The relative percentage of caryophyllene and citronellol tends to increase, while the linalool and citronellal levels decrease due to tested post-harvest treatment. It was implied that for the benefit of the fragrance industry with a high citronellal requirement, EOs should be made from fresh green leaves and the leaves should be avoided from drying and powdering treatment.

Echinochloa crus-galli is a major weed in paddy field that reduces rice yield. The objective of the research was to study the effect of E. crus-galli ecotypes and populations on rice growth and production. The research was conducted in a green house using split plot design with three replications. The main plot consisted of three E. crus-galli ecotypes i.e ecotype from Karawang, Cikampek, and Sukabumi. E. crus-galli population as sub plot consisted of 0, 1, 2, 3, and 4 E. crus-galli per pot. The results showed that ecotype of E. crus-galli affected plant height, number of tiller, and panicle density. The competitivenes against rice of E. crus-galli ecotype Cikampek was higher than that of ecotype Sukabumi and Karawang. Population E. crus-galli affected rice growth and production. Population of E. crus-galli 4/pot decreased spikelets weight about 48.0% and filled spikelets weight about 46.2%. Interaction of ecotype and population of E. crus-galli did not affect rice growth and production. Key words: competition, ecotype, E. crus-galli, population, weed.

The effect of different seed corm weight on the growth and production of elephant foot yams (Amorphophallus paeonifolius Dennst. Nicolson) were studied. Two forms of corm with same weight were prepared, i.e., whole corm and vertically sectioned by 1/2. The fresh mass of each whole corm and corm section was the same. Six different corm weights were compared, i.e., 50, 100, 200, 500, 1000 and 2000 g. Growth and development of elephant foot yam were determined by corm weigth, large seed corm produced larger leaf and fresh mass of daughter corms. On the contrary, number of leaf decreased with increasing seed corm weight. Plants from whole seed corms emerged earlier and they were larger than those from the sectioned corms, irrespective of weight. Plants from small sized whole corm emerged earlier than the larger ones. Dissecting the main bud caused the development of lateral buds, resulted in a delay of leaf emergence. The lower yield obtained by the use of sections might be related to the late emergence leading to shorter vegetative period in the field. In the cultivation, it is recommended to use whole seed corms of 100 or 200 g. Key words : Elephant foot yams, tuber crop, Araceae, corm weight, tuberization rate

The effect of tree litters on rice yield (cv. BR11) was evaluated in the study. Four kinds of tree litter, i.e., ipil-ipil or lamtoro (Leucaena leucocephala (Lamk) De Witt), sissoo (Dalbergia sissoo), akashmoni (Acacia auriculiformis) and mander (Erythrina orientalis) were incorporated into the soil 15 days before transplanting at rate of 5 ton/ha supplemented with inorganic fertilizers (83 kg N, 48 kg P205, 42 kg K20, 10 kg S and 3.6 kg Zn/ha). In the control plots only recommended inorganic fertilizer were applied. Results showed that tree litter application had a significantly positive effect on the yield parameters such as plant height, panicle length, tillers per hill, filled grain and index of 1000-grain weight. Grain yield of plots treated with ipil-ipil, sissoo, akashmoni and mander was 5.61, 4.49, 4.95 and 5.36 ton/ha, and the yield increased over control plots 39.6, 11.7, 23.1 and 33.3%, respectively. It is worthy to note that addition of tree litter to inorganic fertilizer produced significantly higher yield than inorganic fertilizers solely. Among the tree litter, ipil-ipil and mander had the greatest increase in rice yield, while akashmoni was intermediate and sissoo was the least. Key words: Agroforestry residues, rice, sustainable agriculture and tree-based cropping

Biannual bearing fruit is a common phenomenon in tropical fruit trees. However, effectiveness of flowering induction on those fruits is still lack of study. The ojective of the research was to study the effectiveness of flowering induction on pummelo of different fruit load on previous year. Field experiment was conducted at farmer's orchad Bantarmara village, Cisarua, Sumedang Region, West Java (300 m above sea level) from August 2007 to April 2008. Experiment was carried out using Completely Randomize Block Design. Experiment was combination of high crop load and less crop load with strangulation position at main stem and primary branches. The results showed that crop load of previous year (higher and less) with strangulation position at primary branches had significant response to the number of flower clusters, flower buds, bloming flower, fruits formed, and fruit sets as compared to control, when strangulated at primary branches. Nevertheless, amount of fruit sets, level of greenness leaf and leaf area seened were not determined by fruit load non position of strangulation. This finding implies that fruit load management is an important factor in determining the success of flowering induction using strangulation. Key words: fruit load, strangulation, pummelo, flowering induction

Through understanding on seed bank, tea plantation manager enables to plan better weed control. The objective of the study was to identify seed bank of weeds at different ages of tea plantation after prunning. The study was conducted at Perkebunan Teh Tambaksari, Subang, Indonesia. Soil samples were collected from tea field of different pruning years (TP0-2 months after pruning, TP1-16 months after pruning, TP2- 28 months after pruning, and TP3-40 months after pruning) and then watered regularly and exposed to direct sunshine to stimulate propagule germination. Results showed that seed banks were found in all soil samples, indicated that effectiveness of weed control was low. The highest seed bank was found at TP1. Most seed bank was seed, they were Ageratum conyzoides which dominated field of TP0 (SDR 36.58%), TP1 (35.90%), TP2 (41.79%) and TP3 (24.82%), followed by Borreria latifolia with SDR values were 19.50%, 27.26%, 29.40% and 16.14%, respectively. Some species stored both vegetative and generative propagules such as Cyperus sp. and Cyperus cyperoides with SDR value 20.33 % only dominated at age of TP0. Seed bank at area of TP1 and TP2 had high value of community coefficient, i.e., 77.22%, showed both fields had high similarity. This finding implies that effective weed control increases when the control is conducted before the weeds bear seed, where mostly less than 45 days after emergence. Furthermore, thirteen weeds had no seed bank in the field, indicates that weed problem in tea plantation was composed of seed bank and weed propagules from other sites. Key words: Pruning year, seed bank, tea plantation, weed control
