Growth Response of Spider Plant (Cleome gynandra L.) on Plant Population and Phosphorous Levels
No full textThe study focused on establishing Growth Response of Spider Plant (Cleome gynandra L.) on Plant Population and Phosphorous levels due to various recommendations are given on spacing for the same crop by various extension service providers that have made farmers plant the crop using broadcasting, 30 cm x 10 cm, 30 cm x 15 cm and 50 cm x 15 cm, which have not facilitated adequate productivity. The experimental design used was randomised complete block design with three replicates. Three plant spacing of 45x15 cm, 30x15 cm and broadcasting were subjected to five different levels of (0, 20 kg/ha, 30 kg/ha, 40 Kg/ha, 50 Kg/ha). Ten plants per plot were randomly selected and tagged for data collection. The collected data were subjected to analysis of variance (ANOVA) tests using SPSS software. Means were compared using the least significant difference (LSD) test at 5% level of significance. Results indicated that plant height; the number of branches, number of pods and seed yield were significantly affected by spacing and phosphorus levels. The wider spacing and highest level of P had significant effects on the growth of plants and seed yield. The spacing 45× 15 cm had a more positive effect on growth parameters and seeds weight as compared to other spacing(S1 = broadcasting, S2 = 30 x 15 cm). The phosphorus levels of F5 = 50 kgs/ha, F4 = 40 kgs/ha, F3 = 30 kgs/ha and F2 = 20 kg/ha had higher effect on growth and seed yield than the control (F1) by F5 registering much effects than the rest. Accordingly, the spacing of 45x 15 cm with phosphorous level 50 kg/ha is recommended for optimal results in spider plant seed production
Effects of plant population and different levels of phosphorus on seed yield of spider plant (Cleome Gynandra) in Vihiga County.
Get PDFS 587 .M36 2016Cleome gynandra has common names as African cabbage, spider flower, spider wisp, cat's whiskers which is an erect herbaceous biannual herb with hairy, often stems colour ranging from purple to cream and many branches growing to a height of about one meter. It is propagated by seed through sowing directly and thinning done four weeks after planting. It's an African leafy vegetable that is used as a vegetable and as a medicinal plant. It's known to play a key role in providing necessary nutrients such as iron, calcium, zinc, potassium, iodine and Magnesium for human development. It requires well drained loamy soils with an average rainfall of 1700 mm per year; the mean monthly maximum and minimum temperature requirement are 23.8°C and 12.4°C respectively. Farmers producing it, are often .faced with the challenge of which is the favorable spacing and fertilizer use, coupled with land fragmentation and declining soil fertility have resulted to spider plant persistently remaining low thus compromising food security and nutrition. Various recommendation of spacing have been given for the same crop by various extension service providers thus farmers planting ranging from conventional way to various recommendations given by various service providers, thus being prompted to study the effects of spacing / P levels on seed yield of spider plant in Vihiga County. Experimental design used was randomized complete block design with 3 replicates. Three plant spacing of 45 cm x 15 cm, 30 cm x 15 cm and broadcasting were used, subjected to five different levels of P20s ( 0, 20kg/ha, 30kg/ha, 40Kg/ha, 50Kg/ha). Ten plants per plot were randomly selected and tagged for data collection. The collected data were subjected to analysis of variance (ANOV A) tests using SPSS software. Means were compared using the least significant difference (LSD) test at 5% level of significance. Results indicated that plant height; number of branches, number of pods and seed yield were significantly affected by spacing and phosphorus levels. The wider spacing and highest level of P had significant effects on growth of plants and seed yield. The spacing 45 cm x 15 cm had a more positive effect on growth parameters and seeds weight as compared to other spacing (S1 = broadcasting, S2 = 30 cm x 15 cm). The phosphorus levels of F5 = 50kgs/ha, Fa = 40kgs/ha, F3 = 30kgs/ha and F2 = 20kg/ha had higher effect on growth and seed yield than the control (F1) by F5 registering much effects than the rest. Spacing of 45 cm x 15 cm with phosphorous level 50 kg/ha are recommended for optimal results in spider plant seed production
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
