The objective of this research was to evaluate the impact of organic sources (animal manures vs. plant residues at the rate of 10 t ha-1 each) on the productivity of hybrid rice (Oryza sativa L.) production under different levels of phosphorus (0, 30, 60, and 90 kg P ha-1) fertilization. Two separate field experiments were conducted. In experiment (1), impact of three animal manures sources (ca...

Intensive tillage will continuously reduce soil quality, characterized by decreased C-organic. Low C-organic indicates the disturbance of fertility. More conservative management experiments have been done for seven years to restore quality sugarcane (Saccharum officinarum L.) productivity. This research aimed study effect system, bagasse mulch, and their interactions on chemical properties agro...

A field experiment was conducted in the 1998 dry season at Kadawa, Nigeria to determine the effect of different levels of nitrogen (0, 60, 120 or 180 kg N ha ), phosphorus (0, 20 or 40 kg P ha ) and irrigation 1 1 (0.6, 0.8 or 1.0 IW/CPE ratio) on nutrient concentration and accumulation in maize. The experiment was a split plot design with four replications, the main plot was nitrogen level x i...

Grazed pastures represent a potential source of nonpoint pollution. In comparison to other nonpoint sources (e.g., rowcropped lands), relatively little information exists regarding possible magnitudes of pollution from grazed pasture; how that pollution is affected by weather, soil, management and other variables; and how the pollution can be minimized. The objective of this study was to assess...

We conducted a case-control study to examine the role of water stress and various other factors on the development of Phytophthora ramorum cankers in symptomatic (case) and symptomless (control) coast live oak (Quercus agrifolia) and tanoak (Lithocarpus densiflorus). Midday stem water potential (SWP) in Q. agrifolia subject trees ranged from – 0.25 to –3.1 megapascals (MPa). SWP was higher (ind...

The software package DNAVis offers a fast, interactive and real-time visualization of DNA sequences and their comparative genome annotations. DNAVis implements advanced methods of information visualization such as linked views, perspective walls and semantic zooming, in addition to the display of heterologous data in dot plot-like matrix views.

This paper studies simple hyperchaotic circuits consisting of one linear 3-port voltage-controlled current source (ab. VCCS), two linear capacitors and one dependent switched capacitor. The dynamics is described by a normal form equation and a return map can be derived. Using a mapping procedure, it is shown that the circuits exhibit interesting hyperchaotic attractors.

The object of this paper is to analyse the sedimentologic characteristics of old and new terrace sediments from the Pawmpawm River channel. The morphometric characteristics of the terrace materials give credence to the hydrologic dynamics of the river as it performs its core functions of erosion, transportation and deposition with time. The terrace materials are evidenced from their petrographi...
