Impact of Climate Change on Growth and Yield of Maize UsingCERES-Maize Model under Temperate Kashmir

Climate variability has been and continues to be, the principal source of fluctuations in global food production in countries of the developing world and is of serious concern. Process-based models use simplified functions to express the interactions between crop growth and the major environmental factors that affect crops (i.e., climate, soils and management) and many…

Comprehensive Study on Soil Water and Nitrogen Balance of Maize Using CERES Maize Model in DSSAT

Simulated studies indicated that early sowing i.e 15th April (D1) predicted highest grain yield during all the years from 1986-2013. Under irrigated conditions increasing levels of N predicted increased grain and stover yield from N levels up to 90 kg N ha-1. Under irrigated and mulched conditions increased level of N predicted increase in maize…

Characteristics, Fertility Status and Fertility Capabiliy Classification of Vertisols along the Benue Floodplain (North Cameroon)

Vertisols are one of the most fertile soils in the World but crop production is often limited by physical features related to shrink-swell movements under different moisture conditions making management strategies mostly tilted towards soil moisture control. However, most crops grown on Vertisols often show signs of nutritional deficiencies whose causes are not yet fully…

Assessing the Impact of Seasonality on Cross River Gorilla Nest Construction at Kagwene Gorilla Sanctuary, North-West Cameroon: An Advanced Study

The Cross River gorilla, one of the most endangered subspecies of western gorilla (Gorilla gorilla) is endemic to 12 to 14 sites at the Cameroon-Nigeria border, where it is facing enormous threats from habitat loss, bush meat trade and minor climate changes (seasonal changes). In a strive to reduce the enormous stressors on this subspecies,…

Remediation Rates of Microbes in Polluted Crude Oil Soil

Removal rate of Total Petroleum Hydrocarbon Content (TPHC) of a crude oil polluted land was investigated with field experimental data generated from the Research Farm soil at the Federal University of Technology Owerri, Imo State, Nigeria. The artificially polluted soil using crude oil – bonny light – with specific gravity of 0.8323 was analyzed. The…

Groundwater Quality Mapping in Crystalline Rock Aquifers of Tindivanam Taluk, Tamil Nadu Integrating with Remote Sensing, GIS and Space Models

Determination of groundwater quality and quantity in crystalline basement terrains is a complex problem. More than half of the surface area of the continents is covered with hard rocks. In hard rock areas, groundwater is found in cracks and fractures of the local rocks. Hardrocks can typically acquire water tolerable to good quality. It is…

Unconsidered Role of Electric Forces in Polar Snowair Interactions

Processes that occur inside polar snow cover significantly affect polar atmosphere but they are still poorly understood. Most studies consider photochemistry as the dominant mechanism of chemical transformations but recent field data cannot be interpreted only by such photochemical model. A concept is proposed to consider electric phenomena that are well known to physics but…
