Yam-Based Cropping Systems Performances with Herbaceous Legumes and Chemical Fertilizers Authorized by Raphiou Maliki PhD In West Africa, the traditional yam-based cropping systems (shifting cultivation and slash-and-burn) contribute to the deforestation, land degradation and low soil productivity. With the aim of designing more sustainable yam cropping systems, the agronomic research organization in Benin implemented alternative systems including herbaceous legumes ( Aeschynomene histrix and Mucuna pruriens var utilis ) and chemical fertilizers.This study examines the effect of rotations with herbaceous legumes and chemical fertilizers on yam yields and soils, to see how consistent they are for the different farmers within a site, and different sites. A perennial experiment was implemented for 4 years, with 2-year rotations, smallholder farmers’ traditional rotations maize-yam or 1-year Andropogonon gayanus (natural fallow)–yam, with rotations intercropped Aeschynomene ...

The Cause of Increased Effectiveness of Water-In-Oil Emulsion Over Water Application of Trichoderma Ovalisporum on Theobroma Cacao Authorized by Ronald T Collins Experiments in Costa Rica showed that Trichoderma Ovalisporum applied in a water-in-oil (corn oil) emulsion gave significantly better control of frosty pod rot disease on cacao (Theobroma cacao) pods when compared to water applications. Experiments were conducted in Ecuador in 2011 and 2012, to determine whether the effectiveness of the T. ovalisporum was supported by the applied spray characteristics (Volume Median Diameter, number of droplets per cm2, droplet volume per cm2, area coverage per cm2, Relative Span Factor and estimated spores per cm2) as opposed to the creation of an environment conducive to spore germination and colonization of the cacao pod. The relative span factor and number of deposits were not different between the two formulations. The Volume Medium Diameter, droplet volume, Droplet volume...

Infiltration and Swelling Under Capillary Flow Authorized by Robert R Wells The theory of water movement in swelling soils has experienced significant change since Haines, in 1923, first explored the relationships of expansion and subsidence. The present work deals with the swelling associated with the upward movement of water into an initially air-dry clay soil. The movement of the wetting front, cumulative imbibition, and change in sample height are shown to be linear functions of the square root of time. A linear piecewise model is used to estimate the change in the volume fraction of the solid resulting from an increase in the moisture content: relationships between θ and z, and Ï‘ and m result.

Environmental Impact Assessment and Source Identification of Total Suspended Particulate Matter and Some Elements Emitted from a Workplaces in Jordan Authorized by Omar Ali Al Khashman The objective of the present study was to assess the extent and severity of atmospheric particulate concentrations and metal concentration in dust, street dust and soil in the Aqaba Industrial Estate (AIE). Samples of dust, street dust and soil were analyzed for their contents of atmospheric particulate matter and elements (Fe, Cu, Ni, Pb, Zn, Mn and Cr) after digestion with nitric acid. This study shows that analyzed major sources and magnitude of elements pollution. The mean concentrations of the elements were as follows: CFe > CPb > CZn > CCr > CMn > CCu and CCd where C stands for concentration. Zn, Cd and Pb were in high levels in the area close to the workplace, while the chromium level was low. This study indicates that all of the elements are concentrated on the surface...

Yam-Based Cropping Systems Performances with Chemical Fertilizers Authorized by Raphiou Maliki Yam cultivation in West Africa is now confronted with the scarcity of fertile soil available for clearing [2]. In Benin nowadays, farmers hardly have the possibility to rely on long duration fallow and yam is being cultivated in 1 or 2-year herbaceous fallow–yam or maize-yam rotation systems with manual incorporation of residue into the soil. The decline in yam yields under continuous cultivation has led to the largely accepted conclusion that yam requires a high level of natural soil fertility (organic matter and nutrient) (O’Sulllivan and Ernest, 2008). Since the demand for yam keeps increasing due to the continued population growth, reserves of arable land are diminishing, and fallow duration is decreasing. It is becoming necessary to sustainably increase yam productivity in sedentary cropping systems (O’Sullivan and Ernest, 2008). There is a dire need therefore to assess in far...

A Prevalence Study of Ectoparasites on The Long- Eared Hedgehog (Hemiechinus Auritus) in Sohag Governorate, Egypt Authorized by Abd El Aleem SS Desoky Samples of long eared hedgehog Hemiechinus auritus were collected from Sohag area, in the spring 2019. The study shows that the long-eared hedgehog that was infected by 2 ticks, Rhipicephalus Turanicus, Hyalomma sp., and one of fleas, Leptopsylla segnis.
