ABSTRACT<br /><br />Cultivation of the chrysanthemum is usually carried out under the plastic-house to produce high quality flowers, but in some areas such as in Karo (North Sumatera), farmers have grown the plant in the open field using selected varieties for the same purpose. The study was aimed to assess responses of ten varieties of chrysanthemum toward two applications methods of fertilizer which was carried out in open-field at Segunung Experimental Garden, Indonesian Ornamental Crops Research Institute (IOCRI) from July till December 2011. The experiment was arranged in a split-plot design with three replications. The main plot was ten chrysanthemum varieties of Besar Kuning, Merah Hati and Sakuntala; Besar Bandung, Berlian Putih, Matahari Kuning, Mata Kucing, Mata Dewa, Swarna Kencana and Puspita Nusantara. The subplot were  two fertilizer applications methods, Karo and Balithi. Karo: manure 100 kg m-2 and 50 kg m-2 (in month 2), urea 30 g m-2 (in month 3) and Balithi: manure 20 ton ha-1,  urea 200 kg ha-1, 350  kg KCl ha-1 dan 300 kg SP-36 ha-1, supplementary 1.5 g urea m-2, 6 g KNO3 dan 6 g SP-36 m-2. Both methods of  applications can be applied to open field cultivation. Method of fertilizer application significantly affected stem diameter, intensity of disease infection and the time of flower initiation. The Balithi’s fertilizer application significantly reduced the intensity of rust disease on chrysanthemum, while Karo’s fertilizer application significantly increased stem diameter.<br /><br />Keywords: Chrysanthemum, open-field, two fertilization application, stem diameter, rust disease<br /><br />

ABSTRACT This study was conducted in order to verify if the phenological stage and the nitrogen fertilization interfere in the allelopathic activity and in the concentration of potentially allelopathic phenolic compounds of tough lovegrass (Eragrostis plana). The assay consisted of a bifactor 3 (0.100 and 200 kg N ha-1) x 2 (harvested in vegetative and reproductive stages), in a split plot design. The N doses constituted the main plot and the phenological stage during the harvest the subplots, resulting in six treatments. The tough lovegrass plants derived from each of the treatments were subjected to allelopathy bioassays, in which aqueous extracts of the aerial parts were applied to lettuce cypselae (Lactuca sativa) and to phytochemicals tests when ethanolic extracts were used, with subsequent partition with ethyl acetate, followed by a high-performance liquid chromatography analysis. There was nitrogen x phenological stage interaction on biological and chemical attributes. The allelopathic extracts were, in descending order of inhibition of germination, those from plants harvested at the vegetative stage and fertilized with 100 kg N and at the flowering stage with 200 kg N, which showed the highest catechin concentrations. The caffeic, ferulic, p-coumaric and vanillic acids were in a higher concentration in flowered and fertilized plants with 0 or 200 kg N. The management of the nitrogen fertilization and the harvesting age influence the allelopathic activity and the phytochemical composition of tough lovegrass.

The study was done using split plot design interrow spacing as a main plot, and fertilizer and variety as a subplot, where three row spacings (20 cm, 30 cm, and 40 cm) were assigned to the main plot while the factorial combination of four blended (NPSB) fertilizer rates (0 kg/ha, 50 kg/ha, 100 kg/ha, and 150 kg/ha) and representative of Kabuli and Desi type chickpea varieties such as Arerti and Mariye, respectively, were assigned to the subplot. Main effect of interrow spacing did not show significant difference on many studied agronomic parameters. Similarly, main effect of blended fertilizer rates and varieties did not reveal a significant difference for the studied parameters. However, significant differences were obtained on phenology, yield components, and yield for the varieties. Blended fertilizer rates utilized in Tselemti District did not show differences in most of studied traits. Reasonable row spacing of 20 cm for both types of chickpea could be used for the studied area.

O estudo foi desenvolvido em uma lavoura localizada no município de São Mateus-ES, na qual foi estabelecida uma malha amostral irregular com 79 pontos, abrangendo uma área de um hectare.  Para a amostragem da fusariose foi realizado um levantamento, onde uma planta por ponto da malha amostral foi classificada em sadia, doente ou morta.  Os atributos do solo amostrados foram: pH em H2O, matéria orgânica, cálcio, magnésio, potássio e textura do solo. Os dados foram analisados através da estatística descritiva e ferramentas da geoestatística. Os semivariogramas ajustados apresentaram uma forte dependência espacial para as variáveis intensidade da fusariose, altimetria, matéria orgânica, textura do solo, pH, cálcio, magnésio potássio (89, 94, 92, 94, 93, 91, 100 e 85 % respectivamente). Os mapas gerados indicam que não há relação da intensidade da fusariose com os atributos do solo estudados no experimento.Palavra-chave: epidemiologia, Fusarium solani f. sp. piperis, geoestatística, Piper nigrum L. SPATIAL ANALYSIS OF FUSARIOSE AND SOIL ATTRIBUTES IN THE BLACK PEPPER CULTIVATION  ABSTRACT:Black pepper is the most consumed spice in the world, Brazil stands out as one of the largest producers. One of the major constraints in cultivation is fusariosis (Fusarium solani f. Piperis). The objective of this study was characterize the spatial variability of fusariosis in black pepper and verify the relationship of chemical attributes of the soil. The study was developed in a tillage located in the municipality of São Mateus - ES, which exist an irregular sampling network was established with 79 points, covering an area of one hectare. For the sampling of fusariosis intensity, the survey was performed, where one plant per point of the sample mesh was classified as healthy, symptomatic or dead. The attributes of the soil sampled were: pH in H2O, organic matter, nutrient content (calcium, magnesium, potassium) and soil texture. Data were analyzed through descriptive statistics and geostatistics tools. The adjusted semivariograms indicated a strong spatial dependence for the variables intensity of fusariosis, altimetry, organic matter, soil texture, pH, calcium, potassium magnesium (89, 94, 92, 94, 93, 91, 100 and 85%, respectively). The generated maps indicate that there is no relation between the incidence of fusariosis and the soil attributes studied in the experiment.Keywords: epidemiology, Fusarium solani f. sp. piperis, geostatistics, Piper nigrum L. DOI:
