The winged bean (Psophocarpus tetragonolobus L.) is a member of the Fabaceae family (beans). Winged bean is developed as a vegetable, and young winged bean pods can be consumed fresh, steamed, fried, or pickled. In Southeast Asia, winged bean pods are generally cooked or consumed as side dishes or salad. Winged bean contains high protein content equivalent to soybean seed. Besides being rich in protein, vitamins, and minerals, the winged bean also has secondary metabolites, including phenolics and flavonoids. This study aimed to identify secondary metabolites in young pods of two varieties, “Fairuz” and “Sandi”, at two different harvest ages of 8 and 10 days after anthesis (DAA) and provide the biological activity on each identified compound. The experiment was conducted at the IPB experimental field at Leuwikopo, Bogor, from September 2020 to February 2021. The identification of secondary metabolites of the young green pods “Fairuz”, and the young purple pods “Sandi”, was performed using the GCMS method at the Regional Health Laboratory (KESDA) DKI Jakarta. The results of the GCMS analysis showed that 1,2-enzenedicarboxylic acid, mono(2-Ethylhexyl) ester was the most abundant compound identified from pods harvested at 8 DAA in both varieties, namely 42.26% in “Fairuz” and 26.66% in “Sandi”. Other compounds, 9,12,15-Octadecatrienoic acid, ethyl ester, (Z, Z, Z) (Linoleic acid ester), were found in “Fairuz”, whereas (9E,12E)-9,12-Octadecadienoic acid (Linoleic acid) was found in “Sandi”; these compounds are hydroxyl group and phenolic glucoside compounds and are found in pods harvested at 10 DAA.

Indian camphorweed (Pluchea indica Less.) leaves exhibit antioxidant, antibacterial, anti-inflammatory, and antimicrobial activities, indicating significant potential for the pharmaceutical industry. This research aimed to determine the optimal rates of chicken manure for enhancing leaf and total flavonoid production in Pluchea indica. The study took place at the IPB Experimental Station in Bogor, Indonesia,spanning from July to October 2023. A completely randomized block design with a single factor (chicken manure doses) was employed: 0, 2.5, 5, or 7.5 kg per plant. Each treatment comprised three replications, each consisting of 20 plants. The results revealed that the application of chicken manure at 2.5 kg per plant led to significantly taller plants, more leaves, and tertiary branches compared to the control group. Specifically, the 2.5 kg dosage significantly increased the nitrogen content of the 7th leaf and the potassium content of the 3rd leaf. Meanwhile, the application of 5 kg of chicken manure per plant significantly boosted phosphorus content in the 3rd and 7th leaves and potassium content in the 5th and 7th leaves. However, no significant differences were observed in total flavonoid and antioxidant activity across all leaf positions with chicken manure application. Plants receiving 5 kg of manure demonstrated the highest fresh leaf weight (81.64 g) and dry weight (38.27 g), which were significantly greater than those receiving 2.5 kg per plant or no manure. Despite these variations, flavonoid production per plant did not show a significant difference with manure application.

The optimal okra cultivation using organic fertilizers remains a subject of limited information. This study aimed to assess the impact of applying 18 t.ha-1 of laying hens' organic fertilizer on the morphological and physiological traits of the "Naila IPB" green okra variety. The study was conducted between September and December 2022 at the IPB organic experimental field at Cikarawang, Bogor, West Java, Indonesia. A randomized complete block design with a single factor namely frequency of organic fertilizer application, was employed. The factor consisted of four levels: no organic fertilization, 1-, 2-, and 3-times applications. The results demonstrated that a single application of organic fertilizer led to an increase in plant height at 5, 7, and 9 weeks after planting (WAP), leaf number at 5 WAP, root dry weight at 4 WAP, stem dry weight at 10 WAP, and an acceleration in the onset of flowering. This resulted in a flowering period lasting 29.6 days, with a total flowering duration of 69.33 days. In contrast, a two-times application of organic fertilizer resulted in elevated plant height at 11 WAP, an increased leaf number at 11 WAP, heightened leaf potassium content, a greater number of pods per plant, and a higher yield of young pod okra. These findings contribute to our understanding of the effects of organic fertilizer application frequency on the growth and yield of young pod okra, aiding in the formulation of improved cultivation strategies.

The leaves and pods of cowpea (Vigna unguiculata L. Walp) have potential uses as vegetables. This research aimed to assess the impact on cowpea growth and seed yield through different pruning times, methods, intensities, and their interactions. Conducted at the Cikabayan Experimental Field, IPB University, between April and August 2022, the study employed a randomized complete block design with three factors and three replications. The first factor, pruning time (5 and 7 weeks after planting, WAP), represented vegetative and generative phases. The second factor involved pruning methods (leaf and shoot), while the third focused on pruning intensity (0, 10, 30, and 50% of leaf numbers). This resulted in 16 treatment combinations, replicated three times, yielding 48 experimental plots. Measured variables included pruned leaf count, pruned leaf weight, total leaf count, plant fresh and dry weights, cowpea plant C/N ratio analysis, pod wet and dry weights, pod count, pod length, seeds per pod count, 100-seed weight, dry seed weight per plant, dry seed weight per plot, and cowpea seed productivity. Results highlighted significant effects of pruning time, method, and intensity on leaf count, shoot fresh and dry weights, and C/N ratio of cowpea plants after two weeks of pruning. However, the treatments did not significantly influence cowpea seed yield. Pruning cowpea leaves led to an average pruned leaf weight of 30 g per plant, offering a nutritious vegetable source without compromising cowpea seed yield. These leaves commanded a market price of approximately Rp. 6000 per kg, transforming them into a valuable economic asset when utilized as vegetables, thus contributing to the sale of nutritious food.

Bitter gourd (Momordica charantia L.) fruits have been reported to have pharmacological functions such as anti-bacterial, lowering blood sugar, and preventing cardiovascular disease. Terpenoids are the bioactive compounds that play a role in those functions. The phosphorus is essential in the biosynthesis of terpenoids. This research aimed to determine plant growth characteristics, fruit production, and terpenoid production in bitter gourds fertilized with various phosphorus. The experiment was conducted at the IPB experimental station in Cikarawang, 6o32’58.3” S south latitude and 106o43’54.8” E east longitude, Bogor, Indonesia, from July to October 2023. The experiment used a completely randomized block design with a single factor: fertilizer treatments and three replications. The treatments were without fertilizer, chicken manure only, and varying dosages of SP-36 (0, 20, 40, 60 g per plant). Plants treated with 40 g SP-36 per plant significantly had longer stems at four weeks after planting (WAP) (153.5 cm), substantially more female flowers at 5 WAP (6.4 flowers), heavier fresh weight per fruit (243.98 g), and higher fruit carotene level (86 μg.g-1). Plants treated with 60 g SP-36 per plant had the heaviest fresh fruit weight per plant (2,820.9 g). On the other hand, chicken manure fertilizer resulted in an elevated number of female flowers at 7 WAP (6.8 flowers), leaf potassium content (3.41%), chlorophyll a (250 μg.g-1), chlorophyll b (114 μg.g-1), and total chlorophyll concentration (363 μg.g-1). There were no significant differences in IC50, terpenoid content, and terpenoid production; however, plants treated with 60 g SP-36 per plant tended to have lower IC50 (1,347.67 ppm) and terpenoid content (95,227 μmol NE.g-1 dry fruit). In contrast, plants treated with 40 g SP-36 per plant tended to have higher terpenoid production (15,995 mmol NE per plant) than other treatments.

The objective of this experiment was to study nitrogenase activity, nutrient uptake, and growth of two soybean varieties under saturated and dry soil conditions. The experiment was conducted in the plastic house at IPB Experimental Station, Babakan Sawah, Bogor, from August to November 2001. The experiment used the complete randomized design with four replications. The first factor was variety, consisted of Wilis and Bromo. The second factor was water condition, consisted of continuous saturated, saturated-dry, and dry conditions. Wilis and Bromo were not significantly different in nitrogenase activity; P and K uptake; nodule, stalk, leaf, pod, and seed dry weight. Wilis and Bromo were significantly different in root dry weight and leaf N uptake at 3 weeks after planting. Root dry weight and leaf N uptake of Wilis was lower than those of Bromo.The levels of nitrogenase activity, nutrient uptake, and plant weight under different water conditions were in the following order, from low to high, dry, saturated-dry, continuous. Under continuous saturated condition, nitrogenase activity, N uptake, P uptake, K uptake, nodule, root, stalk, leaf, and pod dry weight were 6800 %, 265 %, 320 %, 288 %, 1386 %, 362 %, 289 %, 265 %, 329 % of those under dry condition, respectively at 9 weeks after planting. Key words: Soybean, saturated culture, dry culture, nitrogenase activity, nutrient uptake

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
