Abstract: Ethiopia's teff production, a key cereal crop, has long suffered from blanket fertilizer recommendations that fail to account for the diverse soil conditions across the country. This often leads to suboptimal yields, falling short of the crop's true potential. To address this challenge, Batu Soil Research Center embarked on a ground breaking initiative: developing a phosphorus fertilizer requirement map specifically tailored to the Lume district. To validate the effectiveness of this map, field experiments were conducted across nine peasant associations within the district. Four different fertilizer treatments were compared: unfertilized control plots, plots receiving the conventional blanket recommendation of a uniform 100/100 NPS/Urea application, plots applying phosphorus based on the newly created map (P-map), and plots receiving phosphorus calculated based on individual soil analysis (P-required). The results were striking. P-map emerged as the clear winner, driving the highest yields of both grain (2178 kg ha-1) and biomass (6639 kg ha-1) compared to all other treatments. This impressive performance translated to a significant improvement in harvest index as well, reaching 34.11%. Notably, P-map surpassed not only the control group but also the blanket recommendation, highlighting the limitations of a one-size-fits-all approach. Economic analysis further solidified the case for P-map. For farmers in Lume district, adopting this map-based approach promises a 100% marginal rate of return, making it a highly profitable investment. This economic benefit, coupled with the substantial yield improvements, paves the way for a more sustainable and prosperous future for teff cultivation in the region. In conclusion, the fertilizer requirement map developed by Batu Soil Research Center holds immense potential for revolutionizing teff production in Ethiopia. By moving away from blanket recommendations and embracing a precision-driven approach, farmers in Lume district and beyond can unlock the full potential of this valuable crop, boosting their yields, income, and food security.

Abstract: Socio-economic activities have led to the dispersion of polluting agents in all compartments of the environment. The latter largely reach the sea by air, water or land. Thus they can alter the balance of its ecosystems due to their harmful properties. In return, these physical, chic or biological entities can reach humans through the food chain. Hence knowledge of these contaminants is necessary. Indeed, in Senegal, there is little data relating to fishery products, particularly seafood. Hence such work could contribute to good food security but also would allow us to become better aware of the consequences of the destruction of our environment. In this work the profile of the contamination of Soumbedioune beach by OCPs was studied using gas chromatography coupled with mass spectrometry. The average values of 30,470; 149,983 µg/Kg respectively for heptachlor and aldrin are well above the reference 0.1 µg/Kg. And the values 4,255; 149,98 µg/Kg respectively for DDE and DD. This is greater than 50 µg/Kg for the last. This shows that there is a real environmental and health problem that exists on this Dakar coast. Faced with such a situation, it is appropriate to set up wastewater treatment plants and ensure compliance with the ban on these products dangerous to health. Consequently, awareness on the part of decision-makers, populations and industrialists could probably lead to solutions.
