The soils of the semi-arid areas of northeastern Ethiopia are poor in soil nutrients owing to intensive soil erosion, continuous cereal growing, and age-old cultivation. Consequently, low soil fertility is the most severe constraint to smallholder crop production and to sustainable food security. Farmers in northeastern Ethiopia are also very poor in resource endowment and are incapable of supplying the nutrient requirements of crops through commercial fertilizers. Therefore, integrated nutrient management through the combined use of mineral and organic fertilizer sources is of great importance for the sustainable improvement of soil productivity in intensive cropping systems. This study evaluated the integrated use of mineral fertilizers at the rates of 0%, 50% and 100% of the recommended rates and the organic fertilizer source (farmyard manure, FYM) at the rates of 0, 5, 10, and 15 t ha⁻¹. The results indicated …
