ABSTRACT
Integrated nutrient management not only helps to get economic yield and quality fruits but also helps in maintaining the soil health. The residual effect of nitrogen management on yield as well as fruit and soil quality will be beneficially enhanced. Nutrient management system has now assumed great importance firstly because of the present negative nutrient balance and secondly neither the chemical fertilizers alone nor the organic sources exclusively can achieve the production sustainability of soils as well as crops under highly intensive cropping system. The integrated nutrient management helps in restoring and sustaining soil fertility and crop productivity. The studies revealed that bunch weight and yield of ratoon banana were significantly higher in 25 % N FYM + 75 % N RDF (15.43 kg and 72.92 t ha-1). The application of 25 % N- FYM + 75 % N- RDF treatment recorded higher total nitrogen uptake (400.56 kg ha-1) , application of application of 50 % N- vermicompost + 50 % N- RDF recorded higher total phosphorus uptake (108.58 kg ha-1) and treatment 50 % N- FYM + 50% N-RDF significantly influenced total potassium (1039.60 kg ha-1) uptake by ratoon banana at harvest.
Key words :
