Nutrient partitioning in ‘Ney Poovan’ banana under nitrogen fertigation

Field experiments were carried out to study the pattern of nutrient (N, P & K) accumulation and distribution to different plant parts in banana under nitrogen fertigation. Nitrogen accumulation in leaf, stem and root increased upto 240 days after planting and declined later. Whereas, phosphorus and potassium accumulation decreased after 180 days after planting in all the plant parts. In general, nitrogen content was high in leaf followed by stem, root and rhizome. Nearly, 35 per cent of total nitrogen, 32 per cent of total phosphorus was accounted for by the leaf and around 33 per cent of potassium was accounted for by the root. Drip fertigation (100 g nitrogen) resulted in higher accumulation of nitrogen, phosphorus and potassium as compared to soil application of nitrogen. The fruit yield was also higher with 100g nitrogen applied through drip.
