Bioefficacy of Azadirachta indica A. Juss and Jatropha curcas L. seeds aqueous extracts on Plutella xylostella (L.) (Lepidoptera: Plutellidae)
The diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae) is an important pest of cruciferous crops in Côte d’Ivoire. It is a destructive pest of cabbage and it is developed resistance to many conventional insecticides. This study was carried out to evaluate the repellency and antifeedant effects of Azadirachta indica and Jatropha curcas seeds aqueous extracts on […]
Effets of two plants propagation methods on Jatropha curcas (L.) growth and seeds yield in Tandjilé region (Chad)
Field trial was carried out in Chad to investigate the effects of two plants propagation methods on productivity of Jatropha curcas L. cultivated in four localities (Djoun, Insatal, Laï-Djoum and Tchoua) at Tandjilé region in Chad. Planting was done following a randomized block design with four replications and two treatments (plants propagation methods: cuttings of […]
Effects of 60Co gamma radiation doses on seed germination of Jatropha curcas L.
This study aimed to assess the effects of different gamma radiation doses from Cobalt -60 isotopic source on seed germination and early growth parameters of Jatropha curcas L. Healthy and dry seeds were subjected to three doses of gamma rays (100, 200 and 300 Gy). The experiment was conducted using randomized complete block design, with […]
Phytoremediation potential of Jatropha curcas and Pennisetum clandestinum grown in polluted soil with and without coal fly ash: a case of BCL Cu/Ni mine, Selibe-Phikwe, Botswana
This study was conducted to identify plants which can be used for phytoremediation of the soils east and west of BCL Cu/Ni mine smelter [2.5 km east, 2.5 km west, 20 km west and 55 km west (control) of mine smelter]. Two ascensions of Jatropha curcas (J09 and J05) and Pennisetum clandestinum (Kikuyu) were raised […]
Nutritional and chemical composition of Jatropha curcas (L) seed oil from Nigeria
This study investigated the nutritional and chemical properties of Jatropha curcas (L) seed oil from Abia State, Nigeria using standard analytical methods. Proximate composition results show it is rich in protein (29.4%), carbohydrate (16.89%) and fat (46.89%). Low concentrations of phytonutrients were also detected; alkaloids (1.5g/100g), flavonoids (0.81g/100g). The seed is also rich in essential […]

Solid state fermentation of Jatropha curcas kernel cake with cocktail of fungi
The efficacy of four different fungi (Aspergillus niger, Penicillium sp., Trichoderma harzanium and Trichoderma longibrachiatum) in differentcombinations on the biodegradation of Jatropha curcas kernel cake was evaluated in a completely randomized design model. The inoculated substrates were incubated for 10 days at ambient temperature. The treatments include A (Control without fungi inoculation), B (50% Trichoderma […]
Over expression of Jatropha’s dehydrin jcdhn-2 enhances tolerance to water stress in rice plants
Jatropha curcas’s dehydrin (JC-DHN2) has been previously shown to play a role during natural dehydration process associated with maturation of Jatropha curcas seed. In this study, we generated transformed rice plant (tp) overexpressing Jc-DHN2 gene and examined the role of over expressed gene in improving the drought tolerance. The tp plants showed a stronger growth […]
Ethnobotanical exploration and biodiversity conservation of Mt. Nacolod, Southern Leyte, Philippines
This study was conducted in Mt. Nacolod, Southern Leyte, Philippines, to document traditional healing potential and practices of medicinal plants. The knowledge of traditional healing practices in Southern Leyte is at risk of being lost due to lack of knowledge transfer and an aging population of traditional healers. Focus group discussions were used to document […]
Groundnut rust disease epidemiology and potential sustainable management strategies
Groundnut is an important food and cash crop for the majority of the world’s population. However, diseases have impeded groundnut cultivation in groundnut-growing regions. Of them, groundnut rust disease caused by Puccinia arachidis is one among the major diseases causing more than 50% economic yield losses. For decades, chemical pesticide application has been the most […]
