Abstract

The effects of traditional tillage (hoeing), shallow (15 cm) and deep (23 cm) ploughing, and NPK fertilization on total N, P, and K uptake and dry biomass yield or irrigated wheat (Triticum aestivum L.) were evaluated on a sandy loam soil (Typic Ustipsamment) in Borno State, Nigeria. Ploughing and fertilization significantly decreased organic C and total N contents of the soil, but significantly increased the content of available K. Shallow ploughing in combination with low fertilizer input under irrigation resulted in the highest N and K uptake and highest biomass. Deep ploughing resulted in lower nutrient uptake and lower yield of the wheat biomass than shallow ploughing probably due to accelerated downward movement of both native and applied nutrients.
