Yam-Based Cropping Systems Performances with Herbaceous Legumes and Chemical Fertilizers Authored by Raphiou Maliki 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 histrix with maize-yam...

The Cause of Increased Effectiveness of Water-In-Oil Emulsion Over Water Application of Trichoderma Ovalisporum on Theobroma Cacao Authored by Ronald T Collins Experiments in Costa Rica showed thatTrichoderma 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 and area coverage...

Yam-Based Cropping Systems Performances with Chemical Fertilizers Authored by Raphiou Maliki Yam (Dioscorea spp.) is a tuber crop widely cultivated in the humid and sub-humid lowland regions of West Africa and the Caribbean. More than 90% of the worldwide production (40 million metric tons of fresh tubers year-1) is produced in West Africa [1].   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 gro...

A Prevalence Study of Ectoparasites on The Long- Eared Hedgehog (Hemiechinus Auritus) in Sohag Governorate, Egypt Authored by Abd El Aleem SS Desoky Hedgehogs are small, nocturnal and spiny-coated mammals which are found in synanthropic environments and they are kept as pets by some people [1,2]. As hedgehogs feed on insects, worms, centipedes, snails, mice, frogs, lizards and snakes, they are considered as useful animals for natural ecosystems and are in the protected species list [1]. They are ideal hosts for ecto and endoparasites, because they have active foraging behavior and do not groom themselves [3]. On the other hand, these animals can serve as reservoir for some zoonotic pathogens. Hedgehogs acquire some pathogens through tick or flea bites and are involved in the endemic cycle of these pathogens. Keeping in mind that Hedgehogs are known as potential host for some variants of Anaplasma phagocytophilum, tick–born encephalitis virus (TBEV), Rickettsia felis, Eucoleus aerophil...

Influence of Planting Dates on Cane and Sugar Yields for Some Sugarcane Varieties Authored by Mohamed Owais Ahmed Galal The present study was carried out at El-Mattana Research Station, Luxor Governorate, Agricultural Research Center, Egypt. In two plant crop seasons of 2017/2018 and 2018/2019 to study the effect of planting dates on yield for three sugarcane varieties (G.T.54-9, G.98-28 and G.84-47) grown at three planting date in mid-March, mid-April and mid-May. The date of harvesting was in mid-March for all planting dates. A split plot arranged RCBD, in four replications, was used for the experiment. The three varieties were randomly distributed to the main plot while the three planting dates were assigned to sub-plot. The results indicated that planting sugarcane in mid-March was superior in millable cane/fed, cane weight, as well as cane and sugar yields in both seasons.
