A field experiment was conducted on a Farm in Ekiti South-West Nigeria (Lat.7’37’23 N and log 5’13’15E with 1440 ft. above sea level) to evaluate the performance of two Sunflower genotypic varieties (SAMSUN 1 and SAMSUN 2) as affected by the geographical location and abiotic factors. Soil analysis result showed pH of 5. During the vegetative stage, 61cm was recorded as the highest plant height for SAMSUN 1 and 46cm was recorded as the highest plant height for SAMSUN 2. The number of leaves of SAMSUN 1 was 28 and 24 for SAMSUN 2 after 84days of planting. 1.8cm was recorded as the final stem diameter for SAMSUN 1 and 1.6cm for SAMSUN 2. Harvesting of seeds was carried after 124days of planting; the seed yield for SAMSUN 1 was 3.74kg and 2.96kg for SAMSUN 2. Proximate analysis on the seeds showed that SAMSUN 1 contained 5.88% moisture,1.58% ash, 7.10% crude protein, 3.35% fat and 3.35% crude fiber while SAMSUN 2 contain 4.37% moisture, 2.05% ash, 6.45% crude protein, 4.16% fat and 4.16% crude fiber. Oil extraction was carried out on the seeds of the Sunflower using a Soxlet apparatus and n- hexane as the extraction solvent. 400ml and 460ml of sunflower oil were recorded for the two varieties respectively. The oil composition analysis showed that SAMSUN 1 contained 5.37% moisture, 0.74% ash and 11.91% crude protein and SAMSUM 2 contained 7.12% moisture, 0.72% ash and 13.93% crude protein. The result of the experiment was compared with that from the northern region of Nigeria where it is predominately cultivated. It can be concluded after the whole experiment that sunflower will give more yield and oil in the northern region of Nigeria.

Currently, the existence of mankind is under a serious threat posed by the spread of novel SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) also referred to as COVID-2019 [Coronavirus disease 2019] or 2019-nCoV [2019 novel coronavirus].The number of cases across the globe is still on the increase and there has been an urgent need for therapeutic alternatives to alleviate and fight down this pandemic. It is worthy of note that Africa, with high poverty index is still at the base of the countries ravaged by SARS-CoV-2 and this is not far-fetched. Many Africans over the years have been exposed severally to Mosquito bites and malaria infections against which their bodies having been subjected to several doses of different anti-malaria drugs both clinical and traditional (for those who could not afford the cost of clinical drugs) therefore demonstrate strong immunity against SARS-CoV-2; a virus which responds positively to some of the anti-malaria drugs with anti-viral effects such as Chloroquine and Artemisin in widely distributed across Africa. This mini-review aims at providing a quick idea as to the adaptive immunity buildup against malaria by some Africans (mostly in the sub-Saharan region) in comparison to SARS-CoV-2 fair resistance vis-à-vis the effectiveness of supplementing clinical drugs with traditional herbsas a potential solution to this pandemic outbreak.
