Abstract: A study was conducted during 2017 to 2018 and 2018 to 2019 to find out Effect of nitrogen, phosphorus and potassium fertilization on growth of custard apple Cv. Balanagar (Annona squamosa L.) The custard apple plants were treated with three levels of nitrogen (0,250,350 g N/plant/year), phosphorus (0,125,175 g P₂0₅/plant/year) and potassium (0,125,175 g K₂0/plant/year) in all possible 27 combinations was split in different growth stages, were replicated two times in Factorial Randomized Block Design. Experimental findings revealed that, plant growth was significantly influenced by applied nutrients. Plant height, plant spread E-W, plant spread S-N, plant canopy volume, leaf area and chlorophyll content showed significant improvement with the application of 350 g nitrogen, 125 g phosphorus and 125 g potassium per plant during both the years of experimentation.
