Saturated soil culture (SSC) is a cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. By keeping the water-table constantly, soybean will be avoided from negative effect of inundation on soybean growth because soybean will acclimatize and improve its growth. The objective of the research was to study the response of soybean varieties under saturated soil culture on tidal swamps. The research was conducted at Banyu Urip of Tanjung Lago Sub District, Banyuasin District, South Sumatera Province, Indonesia from April to August 2009. The experiment was arranged in a split plot design with three replications. The main plot was water depth in the furrow consisted of without watering, 10, 20, 30, 40 cm under soil surface (uss). The subplot was soybean variety consisted of Tanggamus, Slamet, Willis, and Anjasmoro. The result showed that the interaction between varieties and water depth significantly affected growth and seed production, except pod numbers/plant. The values of all variables were higher under SSC compared to those cultivated without watering (control), but varieties responded to SSC differently. The highest seed production was obtained from Tanggamus with 40 cm uss, i.e. 4.83 ton/ha but it was not significantly different from those at water depth 20 (4.63 ton/ha) and 30 cm uss (4.71 ton/ha). However, technically and economically, 20 cm uss was the most appropriate water depth for soybean production on tidal swamps. Key words: Glycine max L. (Merr.), water management, water table

Field experiment to study biomass and bioactive compound productions of Talinum triangulare from different propagules and chicken manure dosages was conducted at Leuwikopo, Dramaga, Bogor, West Java, Indonesia from September to November 2005. The research used split plot design with 3 replications. The main plot was propagules (seed and stem cutting) and sub plot was chicken manure dosages (0, 5, 10, and 15 t ha-1). Bioactive compound was determined qualitatively. The results showed that stem cutting gave the highest leaf dry weight (7.78 g plant-1) and tuber dry weight (4.99 g plant-1). The bioactive compounds (alkaloid, steroid, saponin, tannin, and flavonoid) were not influenced by propagules. The dosage of 15 t ha-1 chicken manure gave the highest leaf dry weight (10.73 g plant-1) and tuber dry weight (6.36 g plant-1). The bioactive compound decreased with the increasing chicken manure dosages. Interaction of stem cutting and 15 t ha-1 of chicken manure gave the highest leaf dry weight (12.43 g plant-1). Bioactive compound and tuber dry weight were not influenced by the interaction of propagules and chicken manure dosages. Key words: Bioactive compound, Talinum triangulare, propagules, chicken manure

The study was conducted to investigate the effect of different organic manures and their residues on the production of vegetable soybean. The experiments were conducted at IPB Research Station in Cikarawang, Darmaga, Bogor; in September 2005 to May 2006 and August to December 2006. Single or combination of organic manures (chicken manure, green manure, composts and rice hull ash) was applied in the first experiment; while effect of the residues were investigated in the second experiment. The treatments were arranged in a Completely Randomized Design with 3 replications. Single or the combination of organic manures and the residues did not result in significant difference in all agronomic characters, but chicken manure tended to be the best organic manure when it was used as single application. From these experiments, the highest number of filled pod was 56/plant and the highest fresh weight of filled pod was 48 g/plant from the actual population of + 200.000 plants/ha. Additional result from the experiment was that rice hull ash significantly reduced the intensity of plant pest by 75% from that of control. Key words: vegetable soybean, organic fertilizers, residual effects

The effects of NPK fertilization and plant spacing on leaf anthocyanin production of Talinum triangulare (Jacq.) Willd. were studied. A factorial experiment was used to study the combination of two factors i.e. NPK fertilization (no fertilization, NPK, NP, NK, and PK) and plant spacing (100 cm x 45 cm, 100 cm x 60 cm, 100 cm x 75 cm). These combinations were arranged in randomized block design, with three replications. The result showed that there was no effect of plant spacing and interaction between two factors. Application of NP (minus K) fertilizer gave the lowest value for almost all parameter except shoot/root ratio. This result suggested that fertilization played significant role in increasing anthocyanin production and the limiting factor was potassium. Key words: Talinum triangulare, NPK fertilization, anthocyanin production

The objective of the study was to investigate the effect of chicken manure and green manure Calopogonium mucunoides on the growth and production of vegetable soybean under organic farming system. The study was conducted at IPB research station, Leuwikopo, Darmaga, Bogor from June 2004 to March 2005. The experiment used split plot design with chicken manure dosages (0 and 10 ton/ha) as main plots and seed of green manure dosages (0, 7.5, 15, and 30 ton/ha) as sub plots. Chicken manure significantly resulted in better agronomic characters compared to that of without chicken manure. Green manure significantly increased plant height on 4 to 7 weeks after planting (WAP), number of leaves on 6 WAP. Interaction between chicken manure and green manure significantly influenced fresh weight of root nodule and 100 seeds. Fresh weight of 100 seeds was the highest with the application of either 10 ton chicken manure/ha or 15 kg seed of green manure/ha. Except plant height and number of leaves, generally growth and production of soybean under organic farming system were better than those under conventional farming Key words: Vegetable soybean, organic farming, chicken manure, green manure, Calopogonium mucunoides

Application of inorganic fertilizer resulted in a higher shoot production (at 6 week after planting) and a better quality leaves compared to other treatment. This research revealed that high quality waterleaf can be indicated by some criterias, i.e., higher content of primary metabolites (sugar and protein), secondary metabolites (phenolic, flavonoid, and chlorophyll), and antioxidant capacity (low IC50 value). Therefore, application of inorganic fertilizer in wet season is recommended to produce high yields and high quality water leaf. Keywords: sugar, protein, phenolic, flavonoid, DPPH

ABSTRACTThe awareness of the negative impacts of conventional agriculture has been encouraging people to switch from conventional farming to the organic farming, using organic and biological fertilizers. This farming system changes will influence the character of the plant and the yield. The objective of the research was to investigate the morphophysiology and physicochemical characters of rice with various rates of organic and biological fertilizer. The experiment was conducted at rice field in Karawang and Bogor, West Java, from May to September 2012. The experiment used a single factor randomized block design consisted of three replications with 12 treatments. The first 6 treatments were 0, 2, 4, 6, 8, 10 ton organic fertilizer ha-1, and the other 6 treatments were 0, 2, 4, 6, 8, 10 ton organic fertilizer ha-1 combined with 2 l biological fertilizer ha-1. As control treatment was application of anorganic fertilizer with the rate of 400 kg NPK (30-6-8) ha-1. Plot size was 15 m x 10 m, with a double row spacing (legowo 2:1) (25 cm x 15 cm x 50). The results showed that organic fertilizer either without or with biological fertilizers increased the weight of 1,000 grains and decreased amylose content of rice. The score of leaf color in plants with inorganic fertilizer was higher than those with organic fertilizer.Keywords: amylose, gelatinization temperature, leaf color, water uptake ratio, 1,000 grain weight

ABSTRACTApplication of organic fertilizer into the soil is designated as a source of macro, micro nutrients and organic acids; it also acts as soil ameliorant that improve physical, chemical and biological properties of soil. Application of high rates organic fertilizer has a constraint namely the availability and ease of application. Therefore, it is necessary to learn the use of organic fertilizer with low rates to improve the efficiency of chemical fertilizers. This research was aimed to study the effect of organic and inorganic fertilizers on growth and yield of paddy rice, as well as the efficiency of N, P, K inorganic fertilizer. Field experiment was conducted at Sawah Baru Research Station, University Farm IPB, Bogor, West Java from September to December 2013. The experiment used Randomized Block Design consisted of two factors: rates of organic fertilizer (0, 250, 500, 750, and 1,000 kg ha-1), and rates of inorganic fertilizer (0, 100, 200, 300, and 400 kg ha-1). The results suggested that the application of 1,000 kg organic fertilizer ha-1 + 400 kg inorganic fertilizer ha-1 did not show significant interaction. Application of organic fertilizer alone up to 1,000 kg ha-1 resulted in low growth and yield. Increasing rates of application up to 400 kg inorganic fertilizer ha-1 increased the growth and yield of paddy rice. The highest N efficiency was 89.19% at a rate of 500 kg organic fertilizer ha-1 + 200 kg inorganic fertilizer ha-1, whereas the highest efficiency of P and K, respectively were 69.55% and 92.52% at a rate of 750 kg organic fertilizer ha-1 + 300 kg inorganic fertilizer ha-1.Keywords: NPK, organic fertilizer, paddy rice
