Variability in crop response and nutrient use efficiencies to fertilizer application is quite
common under varying soil and climatic conditions. Understanding such variability is vital to …

The use of fertilizers in balanced and adequate amounts is a prerequisite for increasing crop
productivity and production. Unbalanced plant nutrient management continues to be a major …

Physiological use efficiency (PUE), recovery fraction of applied nutrients and indigenous soil
nutrient supply form the basis of site-specific fertilizer recommendations. To derive these …

The severe decline of soil fertility in Ethiopia is due to inappropriate cropping practices
including monocropping, unbalanced nutrient application, continuous cultivation, removal of …

Efficient use of N fertilizer for maize (Zea mays L.) production is important for maximizing
economic return and minimizing NO3 leaching and/or environmental pollution. A field …

Low soil fertility, particularly nitrogen (N) and Phosphorus (P) are among the most yield-
limiting nutrients in Ethiopia. Due to blanket NP application at the national level, the …

Maize (Zea mays L.) productivity is very low mainly on account of the status of soil fertility in
Ethiopia. Integrated use of organic and inorganic fertilizers for maize production has not …

Appropriate selection of varieties based on agroecologies and application of the right
amount and type of fertilizers based on crop requirements are crucially indispensable to …

Maize response to high nitrogenous fertilization levels is a means among other means to
know maximum productivity, from this perspective, a field nitrogen management trial using …

The potential yield of improved maize varieties usually cannot be fully realised mainly due to
inappropriate soil nutrient management practices in most parts of Ethiopia. Site-specific …
