ABSTRACTWaterleaf shoot (Talinum triangulare (Jacq.) Willd) is consumed as vegetable that contains some metabolites. The purpose of this research was to investigate the effect of organic fertilizer on shoot production and its metabolites i.e. protein, vitamin C, flavonoid, and peroxidase enzyme (POD) activity at 10, 12, and 14 weeks after planting. This experiment was conducted at Leuwikopo Experimental Station, Bogor, Indonesia from November 2012-February 2013. The organic fertilizers applied were cow manure (CM) (12.3 ton ha-1), rock phosphate (RP) (1.5 ton ha-1), and rice-hull ash (RH) (5.5 ton ha-1). These organic fertilizers were combined into four treatments by using minus one test method and one control. Each treatment was repeated three times. The result showed that combination of organic fertilizer had the same effects on shoot production and metabolite content of waterleaf. It showed that the amount of organic fertilizers was not significantly sufficient to contribute nutrients to the plant. Keywords: flavonoid, POD activity, repeated harvesting, Talinum triangulare, vitamin C

Induction of polyploid gametes is one of useful plant polyploidization methods. Some of its benefits are to obtain triploid and tetraploid progenies at the same time by cross and self pollination. Previous research showed that some morphological characters which could be the indications of polyploidy plantlets before the analysis of chromosome number. Colchicine treatment on flower bud of diploid Phalaenopsis amabilis was conducted to determine the effect of colchicine on flower bud development, plantlets morphology and growth, and potential of polyploidy induction based on plantlets morphology. Colchicine concentrations in the experiment were 0, 50, 500, 1,000, and 2,000 mg L-1, with three days duration of treatments with aluminium foil wraps on flower buds. The results showed that high colchicine concentrations (2,000 mg L-1) inhibited flowers blooming of treated flower buds. Based on morphological characters, plantlets were classified into normal and putative polyploid plantlets. Putative polyploid plantlets from colchicine with the concentration of 50, 500, and 1,000 mg L-1 were 71.2, 86.4, and 100.0% respectively.Keywords: colchicine concentration, morphological characters, normal plantlets, putative polyploidy, reproductive organ

The application of organic fertilizer and crop rotation are combination of cultivation system integrally to preserve land fertility. This study aimed to determine the effect of crop residues produced in the first season to reduce organic fertilizer rate for mustard greens cultivation in the second season. The experiment was conducted at IPB organic farm, Cikarawang, Darmaga in April until June 2015. The first season was the first experiment conducted separately for soybean and corn to study different manure types for both crops which the rate of each manure was 20 ton ha-1 for soybean and 25 ton ha-1 for corn. Soybean and corn residues were used in the following season on mustard green cultivation. The experimental design was split plot design with crop residues as main plot, and combination of manure types (chicken, cow, goat) and rates (0, 10 ton ha-1) as sub plot. Data were analyzed using variance. Means were statistically compared with Tukey test at α < 0.05 level. The results showed that the soybean and corn residues can be used as nutrient sources for mustard greens cultivation. The application of manure was not necessary for mustard greens cultivation if soybean or corn residues were added in the second season and there was residues from manure in the first season.Keywords: chicken manure, cow manure, crop residue, goat manure

The research was conducted to study the effect of repellent plants and seed treatments on growth and production of organically grown vegetable soybean. The experiment was carried out at Cikarawang Research Station, Bogor, from September 2005 to May 2006. The organic experiment was arranged in a split plot design using four species of companion plants as repellent plants, i.e. Tagetes erecta, Cymbopogon nardus, Ocimum gratissimum, Tephrosia vogelii, and without repellent plants as the main plot, and seed treatments i.e. galangal oil, Pseudomonas fluorescens, and without seed treatments as sub plot using 3 replications and conventional system (using pesticides) as control. Plants grown under conventional system had a greater fresh pod weight (6.7 kg. 10 m-2) than those in organic system (4.80-5.79 kg. 10 m-2), a lower insect infestation (19.17, 22.92 and 32.50%) and disease prevalence (9.17, 11.42 and 14.42%), at 6, 7 and 8 Week After Planting (WAP) respectively, than the organic system. In the organic experiment, the use of O. gratissimum as repellent plants resulted in a significantly lowest empty pod per plant (0.79 g). T. erecta and O. gratissimum without seed treatment, P. fluorescens without repellent plants, and T. vogelii with galangal oil seed treatment has the significant lowest insect infestation at 6 WAP of 20.67, 23.00, 26.67 and 27.33%, respectively. An organic system using repellent plants had a significantly lower insect infestation at 8 WAP (35.67-40.33%, O. gratissimum being the lowest) than without repellent plants (50.56%). Seed treatments on organic system had the lower disease prevalence at 8 WAP (33.87% on P. fluorescens and 35.47% on galangal oil) than without seed treatments (37.73%). Number of root nodules (11.6-16.7 to 7.8) and root nodules dry weight (0.068- 0.101 to 0.040 g) of the organic system were greater than the conventional system. Soybean without repellent plants had a greater number of harvestable plants (137.3), but it was fewer than the conventional system (158.3)

Polyploidy induction in Phalaenopsis amabilis is one of the methods to increase plant genetic diversity. A highly meristematic condition of protocorm induced by cytokinines may improve the success rate of polyploidy induction. This experiment was aimed to study the effect of Benzylaminopurine (BAP), Thidiazuron (TDZ) and coconut water (CW) in a half concentration of Murashige & Skoog (MS) medium before colchicine treatment on growth, multiplication and the success rate of polyploidy induction on Phalaenopsis amabilis protocorm. The experiment used completely randomized design with one factor, medium treatment (15% of CW); 0.51 mg L-1 BAP; 0.50 mg L-1 TDZ; 15% CW + 0.51 mg L-1 BAP; 15% CW + 0.50 mg L-1 TDZ). Each treatment consisted of three replications with five culture bottles of protocorm for each replication and ten protocorms per bottle. The protocorms were incubated for eight weeks in the medium before treated with 50 mg L-1 of colchicine for ten days. The results showed that 15% CW, 15% CW + 0.51 mg L-1 BAP or 0.5 mg L-1 TDZ gave the highest percentage (100%) of alive protocorm. The highest percentage of protocorm multiplication were resulted from 15% CW+0.51 mg L-1 BAP (65.3%) and 15% CW + 0.5 mg L-1 TDZ (62.7%). The best treatment to promote formation of leaves and roots from protocorm was 15% CW. The percentage of polyploid plantlets of 3% was found in plantlet from 15% CW + 0.50 mg L-1 TDZ media treatment while from other treatments could not be detected.Keywords: BAP, chromosome, coconut water, plantlet, TDZ

Moringa is drought tolerant and its leaf is traditionally used as a vegetable. Recently, the leaf is used commercially in traditional medicine and functional foods. Fulvic acid is a kind of plant growth regulator derived from humic acid and is considered a fertilizer in sustainable agriculture. The objective of the research was to determine the effect of fulvic acid concentration on the growth, biomass, phosphorus and flavonoids contents of moringa seedlings. The experiment was conducted from July 2020 to January 2021 at Leuwikopo Experimental Station, Bogor. The treatment was arranged in a randomized block design consisting of two factors, i.e., fulvic acid level (0, 1, 2, 3, and 4 mL L-1) and moringa accessions (East Nusa Tenggara-ENT and Leuwikopo-LWK). Observation focused on growth and biomass, total flavonoids, and phosphorus contents of leaves. The results showed that fulvic acid enhanced leaf growth, and plant height. On the other hand, the fulvic acid application had no significant effect on biomass production, total flavonoids, and phosphorus contents of moringa leaves. Accessions expressed different responses to fulvic acid levels, i.e.e, the fulvic acid of 1 mL L-1 seemed favorable for ENT accession while 2 mL L-1 was favorable for LWK accession as indicated by the level of flavonoid content. Therefore, fulvic acid is beneficial in moringa cultivation, particularly for ENT accession. It is interesting to evaluate the fulvic acid application on moringa trees grown in ENT where soil moisture is considered low.
