Abstract
Fertilizer placement with and close to the seed may have inhibitory effects on early growth of plants. In a pot study, chickpea (Cicer arietinum L.) root growth and nodulation was assessed by placing triple superphosphate (TSP) with seed (0) and 2 or 5 cm directly below the seed and in a control (TSP mixed thoroughly with the top 10 cm of soil) using a sand and a clay loam soil. Phosphorus fertilizer with and close to the seed produced necrotic symptoms in the lower leaves and reduced total root length, root surface area and nodule dry weight in sand. In clay loam there was no specific response of banding TSP, but most measured parameters were lower in the 0 and 2 cm treatments. TSP banding with and close to (<5 cm) the seed inhibited early growth of chickpea, especially in sandy soil, but less so in clay loam soil.
