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

using complete randomized block design with three replications. The means from each plot were compared by using t-student’s test. 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) Mualim, Leo; Aziz, Sandra Arifin; Susanto, Slamet; Melati, Maya

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

Mexican sunflower (Tithonia diversifolia) is a invansive weed but it can be used as continuous and on-farm source of nutrient for organic farming system. The objective of this study was to investigate growth and biomass production of T. diversifolia with different rates of chicken manure and plant spacings. The experiment was conducted at Cikarawang, Bogor, on Inceptisol soil type, from October 2011 until January 2012. The experiment was arranged in a randomized block design with 2 factors and 3 replications. The rates of chicken manure were 0, 2.5, 5 and 10 ton ha-1, while the plant spacings were 50 cm x 50 cm and 75 cm x 75 cm. The interaction effect between manure rates and plant spacing was significant on nett assimilation rate at 4-8 weeks after planting, but it was not significant on biomass production. The highest dry weight of biomass (1,129.1 kg ha-1) was obtained from the addition of 10 ton chicken manure ha-1 with the potential contribution as much as 55.47 kg N, 4.54 kg P, 88.54 kg K per hectare. The highest dry weight of biomass produced with planting distance 50 cm x 50 cm (897 kg ha-1). Referring to the results, it can be recommended that the cultivation of T. diversifolia at the first planting needs 10 ton chicken manure ha-1 and the planting distance of 50 cm x 50 cm.Keywords: biomass production, Mexican sun flower, nett assimilation ratio, nutrient contributio, weed

ABSTRACTBambara groundnut is considered tolerant to drought and unfertile soil; therefore, has higher potential to be cultivated. The average yield of dry pod weight from agricultural fields in Indonesia is still low (< 4 ton ha-1); hence, the cultivation technique must be improved. Fertilizer is the main input to increase yield of Bambara groundnut, but the optimum rates of N, P, and K have not been determined. Therefore, the objectives of the research were to determine the optimum rate of N, P, and K fertilizer for Bambara groundnut production. Three parallel experiments were conducted at Cikarawang Experimental State, Dramaga, Bogor from March to July 2013. Each experiment tested different rates of N or P or K fertilizer with compeletely randomized block design and three replications. The fertilizer rates were 0, 50, 100, 150, and 200% of recommendation rate (100% N = 100 kg Urea ha-1, 100% P = 150 kg SP-36 ha-1, 100% K = 75 kg KCl ha-1). The results showed that leaf P content increased linearly with N fertilizer application. Leaf N content linearly decreased with P fertilizer application. Leaf P content and shoot dry weight quadratically increased with K fertilizer application. The optimum rates of N and P fertilizer was unable to be determined due to insignificant response of several variables. Optimum rate of K fertilizer ranged 86.4-118.95 kg KCl ha-1.Keywords: leaf nutrients, multi nutrient response, recommendation rate

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

Okra fruit contains phenolic compounds as natural antioxidant. The aim of this research was to analyze the effect of different types of fertilizers on production and quality of two okra varieties. The experiment was conducted in October 2017 to February 2018 at Bogor Agricultural University experimental field at Leuwikopo, Darmaga, Bogor (-6033’49.3”SL, 106043’30.7’’EL). The experiment used nested randomized complete block design with 2 factors and 4 replications. The first factor consisted of two okra varieties with different colour (red and green okra). The second factor was fertilizer types consisted of no fertilizer, organic (cow manure), combination of organic + inorganic, and inorganic fertilizer. The results showed that fertilizer types significantly affected plant height and fruit N content but did not affect fruit production. Red okra had a higher plant height, lower number of leaves and leaf K content than those of the green okra. The interaction effect of both factors was significant on total phenolic content in fruit and P content in leaf. The highest total phenolic content in fruit was showed by red okra with inorganic fertilizer, although it was not significantly different to those of red okra with combination organic + inorganic fertilizer, and also to green okra with organic fertilizer. The highest P content in leaf was found in red okra without fertilizer, however it was not significantly different to red okra with combination organic + inorganic fertilizer, green okra with organic fertilizer, and green okra with inorganic fertilizer.Keywords: inorganic fertilizer, leaf nutrient, organic fertilizer, phenolic compound
