Effect of crop rotation and nitrogen fertilization on yield and nitrogen efficiency in maize in the northern Guinea savanna of Nigeria
Two crop rotation cycles were evaluated to determine the effect of cropping systems and N fertilization on the yield and efficiency of N in maize. Maize was grown on plots which had previously supported monocrops of two genotypes each of soybean (TGx 1448-2E and SAMSOY-2) and cowpea (IT 96D-724 and SAMPEA-7), natural fallow and maize. In a split-plot experimental design, three N fertilizer rates (30, 60 and 90 kg ha-1)...

Effects of carbon and nitrogen sources and ratio on the germination, growth and sporulation characteristics of Metarhizium anisopliae and Beauveria bassiana isolates
The entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana are ubiquitous and widespread with well documented broad-spectrum myco-pesticidal effects. It has been reported that nutrient source is an integral determinant of growth and virulence of entomopathogenic fungi. Nutrient based studies also impart light towards the identification of most commendable media for laboratory assays as...

Effect of storage and heat treatments on the germination of oil palm (Elaeis guineensis Jacq.) seed
Oil palm (Elaeis guineensis Jacq.) is a perennial tropical tree which reproduces only by seeds. In the nature, the seeds have a relative dormancy leading to very long germination process (1 to 3 years). In order to improve oil palm production, research aiming at the reduction of the dormancy period was initiated. The germination tests carried on seeds stored for different periods after harvest, showed a germination...

Flood forecasting based on geographical information system
Floodplain management is a recently new and applied method at the river engineering and is essential for prediction of flood hazards. On the other hand, for the purpose of managing and performing all river training practices, it is necessary to simulate complicated hydraulic behavior of the river in a more simple way. In this research, steady flow was simulated along ~4 km end of Zaremrood River (upstream of the Tajan...

Analysis of biogas production in Turkey utilising three different materials and two scenarios
It is a reality for many developing countries, such as Turkey, that a lack of comprehensive evaluation of agricultural and animal potentials can prevent these sectors from becoming optimised to its maximum economical efficiency. Very high input costs, especially for fuel, fertiliser and electricity, result in decreased production; in combination with increased production costs, these are typical reasons for lack of...
