1. 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... |
2. Sensor Based In-Season Nitrogen Determination for Quality Protein Maize on Farmers Field Western EthiopiaQuality protein maize production is a current common practice and widely produced in western Ethiopia but its productivity is negatively affected by low rate and time of nitrogen application but there is still inadequate research on this phenomenon in quality protein maize production. This in view different attempts have been made to solve the soil fertility problems using sensor-based nitrogen management in southwestern and western Ethiopia. The objectives of this review were to summarize past... T. Abera |
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. 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.

5. 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 |
