1. Soil fertility mapping of Dry savannah zone of TogoIncreasing agricultural productivity and therefore the production requires a good knowledge of the soil fertility status and a sustainable nutrients management. The objective of this study is to map spatial distribution of some selected soil fertility parameters in the dry savannah agro-ecological zone that covers the regions of Savanes and Kara in Togo. Soil fertility parameters such as pH, available phosphorus (P), exchangeable potassium (K) and organic matter were determined in soil samples... K.K. Ganyo, K.A. Ablede , K. Koudjega, S. Ani, K.

2. Determining Nutrients rates for Maize, Rice, Cotton, and Tomato in Dry Savannah zone of Togo based on site specific nutrient management approachInadequate fertilizer application limits crop yields and lead to the soil fertility depletion. This study aims at formulating nutrients rates recommendations for main the crops in dry savannah zone of Togo. Site specific nutrient management approach based on spatial variations in nutrients status, crops nutrients requirement and average crop yields under field conditions was used to determine recommendations rates in N, P and K. For maize cropping, nutrients needs are 94 kgN.ha-1, 42... |
3. Climate Smart Agriculture: Constraints, Challenges and Opportunities to Promote the System in EthiopiaAgriculture is vital to the economy of Ethiopia and its development has significant implications for food security and poverty reduction. An increase in agricultural production over the past decades has been due to land area expansion, with a modest change in production techniques and improvement in yields. Yet, the substantial reliance of the sector on rain-fed systems has made it particularly vulnerable to variability in rainfall and temperature and climate change. Climate change may decrease... G.

4. Public Financing in Agricultural Research Development and Rural Poverty Alleviation: Evidence from West African Economic and Monetary Union StatesThe paper examines the effects of public financing for agricultural research and development on rural poverty based on the variable farm income in the West African Economic and Monetary Union (WAEMU) States. To conduct this analysis, a dynamic panel comprising seven (07) WAEMU States has been built based on secondary data from World Bank, African Development Bank (AfDB) and Food and Agriculture Organization (FAO) databases for the period 2000 to 2016. To correct the endogeneity generated by... O. Dah, T. Bassolet |
5. Potato Yield Prediction Using Multi-temporal Sentinel-2 Data and Multiple Linear RegressionTraditional potato growth models have a number of flaws, i.e., the cost of data collection, quality of input data, and the absence of spatial information in some cases. To address these challenges, we created a multiple linear regression model (MLRM) that uses the multi-temporal Sentinel-2 derived indices to predict potato yield. Along the growing season (from October 2019 to February 2020) eight Sentinel-2 imageries were collected, afterwards, the normalized difference vegetation index (NDVI)... M.E.

6. Nitrogen Use Efficiency of Barley Grown Under Organic Amendments and N Fertilizer on Acidic Soils of a Highland Tropical EnvironmentSoil nutrient depletion and low nutrient use efficiency are among pressing issues for the productivity of crops in Sub-Saharan Africa. Efficient use of nitrogen (N) for crop production in low-input subsistence farming may improve yields and quality, reduce cost and risk in case of crop failure. The effects of organic amendments and N fertilizer on the N-uptake and N-use efficiency of barley were investigated in the central Ethiopian highlands. The treatments were factorial combinations of no organic... G. Agegnehu |
7. Use of Digital Extension Tools for Agricultural Information Management Among Cassava Value Chain Actors in Ibadan Metropolis, Oyo State, NigeriaPoor coverage of farmers by extension services and other limitations necessitates adapting the agricultural process to new opportunities, including digital extension. This is more important for cassava value chain actors given the recognition of the crop for food security in Nigeria and its widespread promotion by several local and regional development interventions. Therefore, the use of digital extension tools for agricultural information management among cassava value chain actors in... O. Fadairo, A.M. Durojaiye, R. Adegbayi |
