This study focused on the biological potential activity of total phenolic compounds extracted by soxhlet method from <em>Ocimum</em> <em>gratissimum</em> leaves (Lamiaceae), a popular medicinal plant harvested at Daloa (Côte d’Ivoire).</p> <p><strong>Study Design:</strong> Activities were directed on the <em>in vitro </em>antifungal and antioxidant activities combined to phenolic compounds analysis.</p> <p><strong>Place and Duration of Study:</strong> The study was carried out at the Department of Environment and Plant Protection, and Laboratory of Chemistry and Biochemistry, University of Agricultural Sciences and Veterinary Medicine (USAMV) between March to July 2014, Laboratory of Biochemistry and Microbiology (Bioactives Natural Substances Unit), Jean Lorougnon Guédé University between September 2014 to January 2015.</p> <p><strong>Methodology:</strong> The extract obtained named TPCOG was tested against <em>Fusarium</em> species for its antifungal activity by applying agar slant double dilution method and for its antioxidant activity by DPPH radical scavenging assay. Qualitative and quantitative evaluation of phenolic compounds were carried out by HPLC analysis method with sigma chemical standards.</p> <p><strong>Results:</strong> Tests showed that TPCOG was a powerful antifungal extract with MIC and MFC ranging between 3.125 µg/mL to 12.5 µg/mL. This extract was fungicidal and its antioxidant activity reached F= 541.25± .25 mM Trolox/mL (I= 70 ±1.85%) with a total phenolic content equal 195.70±1.33 mg GAE/g. Radical scavenge and antifungal activities correlated very well with total phenolic compounds. Phenolic content analysis showed presence of phenolic acids and flavonoids with a higher concentration for Quercetin (393.475 mg/100 g sample).</p> <p><strong>Conclusion:</strong> All this results demonstrated the biological potential activity of total phenolic compounds extracted from leaves of <em>O</em>. <em>gratissimum</em> and the possibility to use it in replace to essential oil for the formulation of biofungicides and nutraceuticals by industries.</p> Kporou Kouassi Elisée, Adela Pintea, Okou Obou Constantin, Antonia Odagiu, N’guessan Jean David, Djaman Allico Joseph ##submission.copyrightStatement## https://journalarja.com/index.php/ARJA/article/view/30108 Thu, 17 Dec 2020 00:00:00 +0000 Socio-Demography, Pesticides Use, and Health Status of Rice Farmers in Region XII, Mindanao, Philippines https://journalarja.com/index.php/ARJA/article/view/30109 <p>The socio-demographic characteristics, pesticides use and health status of 300 rice farmers from Region 12 in the Philippines in 2015 were assessed. Likewise, the influence of the socio-demographic characteristics on the farmers’ pesticides use and health status was determined. This was done to describe the current well-being of farmers as basis for recommending strategies to improve their farming practices and health condition. Farmers were middle adults (60.6%), married (83.7%), had secondary education (50.7%), with household size of 1-4 members (62.7%), mostly non-owners (63.3%) of less than 3 hectares of land (91.7%), with total annual income of less than P101,000.00 (69.3%), nearly one third had more than 11 years farming and pesticides application experience and had availed at least one training on rice production for the last five years. Nearly 75% had health insurance. The socio-demographic characteristics did not influence significantly the pesticides use as to frequency and quantity of application and health status of the farmers. Age, however, is found a significant predictor of pesticides use as to frequency of application while civil status and farm ownership are the significant predictors of gaining normal health status as to Body Mass Index (BMI). Based on the findings, farmers still need more trainings on proper pesticides use and other farm technology options to keep their health protected and earn better profits from farming.</p> Mitos D.

It supports the livelihood of approximately four million Kenyans through food provision, income generation and employment. However, milk production per individual animal in Kenya, averaging six to seven (6-7) litres/cow/day, is low compared to the world’s best at 10,133 litres/cow/year (28 litres/cow/day) mainly due to factors including poor feeding. This means that Kenya produces an average of 20 litres of milk less per cow per day compared to the world’s best. The objective of this study was to determine the effect of mineral mix and concentrate feeds on milk revenue of smallholder dairy farmers in Kapseret sub County. The study was conducted between the months of January-March, 2020. Primary data was collected using closed and open ended questionnaires. Spearman’s Rank correlation was used to show the strength of the relationship between the variables. Multiple regression model was employed to assess the effect of supplementation on milk revenue. Results were presented in tables, and descriptive statistics such as percentages and frequencies. The results indicated a positive and statistically significant relationship between the variables (concentrate feeds and mineral mix) and milk revenue at (r=0.41, p=0.001) and (r=0.30, p=0.001), respectively. The relationship between mineral mix and concentrate feeds was positive and statistically significant (r=0.92, p=0.001). Subsequent feeding of homemade or commercial concentrates and mineral mix to dairy animals influenced milk revenue. The study concluded that mineral mix and concentrate feeds increased milk revenue of smallholder dairy farmers in Kapseret sub County. The study recommended the use of mineral mix and commercial concentrates or quality homemade concentrates in order to increase milk produce which affects farmers’ milk revenue.</p> J. K. Bett, S. W.
