Abstract

Chrysanthemum is an ornamental plant that people likes, grows the whole year, and has high economic value.  This study was aimed at assessing the effects of planting density and  concentration ofNPK fertilizer on the growth of potted chrysanthemum.  The study was conducted in a plastic house at the Indonesian Ornamental Crops Research Institute (IOCRI), Cipanas, Cianjur, West Java from March to June 2017.  Shoot cuttings of ±7 cm of potted chrysanthemum of Avanthe Agrihorti cultivar were used.  A completely randomized design in a factorial pattern with factors was used.  The first factor was planting density and the second factor was concentrationof NPK (16:16:16) fertilizer.  The planting density consisted of 5, 6, and 7 shoot cuttings and concentrationof NPK fertilizer were 150, 200, 250, and 300 ppm.  Results showed that planting density significantly affected stem diameter, number of buds, and width of canopy.  No effect concentrationof fertilizer was found on all variables. Keywords: potted chrysanthemum, planting density, NPK fertilizer

Abstract

One problem for developing small white ginger (Zingiber officinale var.  amarum) is the availability of high quality rhizome seeds in right  quantity and time. Seed rhizome will sprout quickly, and its quality will decreased in immature seed rhizome and in not good storage conditions. The main objective of the experiment was to study the best storage room conditions for storage rhizome seeds of small white ginger.  The experiment was conducted in seed laboratory and storage room of Research Institute for Medicinal and Aromatic Crops Bogor. The experiment  was conducted by randomized complete design with nine different storage, 3 replication and 25 samples each treatment.  The treatments are 1) rhizome seeds  storage in room temperature (control),(2) rhizome seeds storage in AC room (16–240C),(3) rhizome seed  soaked in paclobutrazol 1000 ppm for 4 hours then seeds storage  in room temperature ( 4) put rhizome seeds in rack and cover by straw, storage in   room temperature (5) rhizome seed storage on straws in the greenhouse ( 6) rhizome seed storage in the greenhouse without straw ( 7) rhizome seed soaked in water during 1 hour every  month then dried naturally in 300C and storage  in AC room (8) rhizome seed soaked in paclobutrazol 1000 ppm for 4 hour then storage  in AC room ( 9) put rhizome  in wood box and cover by rice straw and husk. Variables observed include moisture contents of ginger seed, lost weight of seed and germination percentage of rhizome seeds at the end of storage period. The result of experiment indicated that  the moisture content and weight rhizome seeds decrease after 2 months. After four months storage period, moisture content was still high  above 80 %, except rhizome seeds in under ground.  The rhizome seeds that store in AC room showed the best performance and thus, this treatment can be recommended for storage of small white ginger rhizome seeds for 4 months. The low moisture content  (< 80%) of rhizome small white ginger seeds will decreased  its viability.   Keywords: Zingiber officinale, seed, storage, viability

Abstract

This study aims to obtain qualified seedlings, and speed up the rooting of some varieties of chrysanthemum (Chrysanthemum morifolium R.) cuttings use synthetic and naturally plant growth regulator (auxin).  Research results are expected to be an alternative method of application effective and environmentally friendly plant growth regulator. The research was conducted from March to April 2013 at the Research Institute of Ornamental Plants (Balai Penelitian Tanaman Hias). The experimental design used is completely randomized design (CRD) factorial. The first factor is the type of auxin which consists of four levels ie control, indole acetic acid (IAA), naphthalene acetic acid (NAA), pregnant cow urine, and not pregnant cow urine. The second factor is the type of chrysanthemum varieties which consists of four levels ie spray type of Puspita Pelangi, spray type of Puspita Nusantara, standard type of Sakuntala, and standard type of Pasopati. The results showed that type of chrysanthemum cultivars and type of auxin not affected the percentage of live cuttings, percentage of rooted cuttings and percentage of sprouted cuttings. The cuttings root of plant that given by pregnant cow urine is better than other treatments. Cuttings root length, and number of primary root of Pasopati is better than other cultivars. The interaction influence between the type of auxin and chrysanthemum cultivars found only in the number of secondary roots, diameter of root and length of the shoot cuttings at 12 DAP.Keywords: Chrysanthemum morifolium R., cow urine, NAA, spray type

Abstract

The experiment was conducted at Gunung Putri Experimental Station and PlantPhysiology Laboratory of Indonesian Medicinal and Aromatic Crops Research Institute(IMACRI), from November 2008 to July 2009. The aim of the experiment was to determinephysiological maturity of Pimpinella pruatjan seed and to study its morphological structures.Observation and sampling using one hundred plants with four replications. Results of theexperiment showed that the physiological seed maturity on the first and third umbell of P.Pruatjan was achieved at 7 weeks after anthesis, and physiological seed maturity on thesecond umbell was achieved at 8 weeks after anthesis. Seed dry weight on the physiologicalseed maturity on first, second and third umbells were 166,87; 158,20, and 141,35 mg/100pericarp, respectively. Germination percentage and germination speed on the first, secondand third umbells were 5,75 % and 0,22 %/etmal; 22,75 % and 0,94 %/etmal; 10,50 % and0,38 %/etmal, respectively.Keywords: flowering, pruatjan, seed quality, morphology

Abstract

This study was aimed at assessing the response of cherry tomato to planting mediacomposition and SP-36 fertilizer rates. A factorial completely randomized design with two factorswas used. The first factor was planting media compositions, namely 100% soil, soil + rice huskcharcoal (1:1), soil + manure (1:1), rice husk charcoal + manure (1:1) and soil + rice huskcharcoal + manure (1:1:1). The second factor was SP-36 fertilizer rates, namely no fertilizer (0%R); 155.5 kg/ha (50% R); 311 kg/ha (100% R) and 466.5 kg/ha (150% R). The recommended rate(R) was 311 kg/ha. Results showed that cherry tomato plants grown in planting medium of soil +manure significantly had higher plant height, number of leaves, number of fruits and total solublesolid content than plants grown in the other planting media. Administration of SP-36 fertilizer indifferent rates was not found to significantly affect the growth, production and fruit quality of cherrytomatoes. Cherry tomato grown in planting medium of soil + rice husk charcoal + manure andfertilized with recommended rate of SP-36 fertilizer (100% R) produced the highest fruit/plantweight and saleable fruit weight.Keywords: cherry tomato, total soluble solid, saleable fruit, rice husk charcoal, manure

Abstract

This study was aimed at assessing the response of sweetcorn plant on various dosages ofbiofertilizer and synthetic (N, P and K) fertilizer. The study was done in May to September 2014 atthe Agrotechnology Trial Farm of Djuanda University. A factorial completely randomized designwas used. The first and second factor were biofertilizer and synthetic fertilizer dosage (0%, 50 %,100% and 150% R/Recommendation). Results showed that adding biofertilizer and syntheticfertilizer until 100% R increased leaf area, length and weight of ear, root and biomass weight andTSS (total soluble solids) content. At various level of biofertilizer, increasing synthetic fertilizerdosages until 100% R could improve plant height, leaves and root number, stem girth, ear lengthand accelerate growing of staminate and pistillate. Meanwhile at various degree of syntheticfertilizer dosage, raising bofertilizer dosage until 150% R tend to higher plant height, and until100% R caused stem girth and root length greater, but delayed staminate and pistillate growth.Application of biofertlizer and synthetic fertilizer tend to increasing pH and cation exchangecapacity of growth medium.Keywords: weight of ear, pH, cation enxchange capacity
