This study set out to analyses rice total factor productivity in Nigeria ecological zones and the growth trend from 1996 to 2010. Statistical information on domestic and imported quantities of rice was obtained for 15 years (1996 to 2010) from the AGROSTAT system of the statistical division of the Food and Agriculture Organization (FAO), Federal Ministry of Agriculture statistical bulletins, Ce...

in order to investigate the effects of plant growth promoting bacteria on growth characteristic of wheat, an experiment was conducted at the research greenhouse, faculty of agriculture, ferdowsi university of mashhad, iran, in year 2009. a completely randomized design based on factorial arrangement (3×6) with three replications was used. the first factor consisted of three cultivars of wheat (c...

The present study was undertaken to explore the bioherbicidal potential of essential oil(EO)(25 to 250μg/ml) from Eucalyptus tereticornis against one of the major weed of rice (Oryza sativa L.), i.e. Echinochloa crus – galli L. considering percent germination, root length and shoot length development chlorophyll, protein and carbohydrate content and percent cellular respiration). Studies reveal...

Bronchial tree casts were made from one or both lungs from nine children aged from five weeks to 17 years. The branches of the casts were ordered by the method of Strahler, and diameter ratio, length ratio, and branching ratio were determined. From five to 12 weeks the diameter ratio is about 1.35, but by 13 months it has risen to 1.45, indicating a faster rate of growth in the larger airways o...

BACKGROUND The purpose of this study was to evaluate the effects of benzalkonium (BAK)-free travoprost monotherapy administered for 3 years on intraocular pressure and visual field performance. METHODS The intraocular pressure of 76 patients with normal tension glaucoma was monitored every 1-3 months. A Humphrey visual field test was performed every 6 months after treatment and compared with ...

The cotton (Gossypium herbaceum L.) was analyzed for changes in physiological and morphological parameters under the influence of water stress. The deleterious effect of water stress i.e., drought in cotton plants was mainly targeted towards physiological and morphological characteristics. The gas-exchange parameters of net photosynthesis (P N ), stomatal conductance (g s ), electron transport ...

[1] The critical point hypothesis for large earthquakes predicts two different precursory phenomena in space and time, an accelerating moment release and the growth of the spatial correlation length. The objective of this work is to investigate both methods with respect to their predictive power. A systematic statistical test based on appropriate random earthquake catalogs allows to quantify th...

A study was conducted on the length-weight relationship, condition factor and the sex ratio of 14,466 fish representing 46 species belonging to 28 genera from 16 families of economically important freshwater fishes inhabiting the 200 km length of Cross River inlands wetlands, Nigeria. Fish samples were collected with artisanal gears (gillnets, cast nets, seine nets) during January 2006 and Dece...
