Abstract: The work was carried out during 2014- 2016 at Horticulture farm under Department of Horticulture and Post Harvest Technology, Institute of Agriculture, Visva Bharati, Sriniketan to study the Effect of Integrated Nutrient Management on Growth and Yield of Pineapple (cv. Kew). The experiment was carried out in a Randomized Block Design with three replications. Treatment consisted of 9 treatment combinations viz., T1= Control; T2= 20t/ha FYM + 100% of recommended dose of fertilizer (RDF) of NPK; T3= 30t/ha FYM + 75% of RDF of NPK; T4= 5 t/ha Vermicompost + 100% of RDF of NPK; T5= 7.5 t/ha Vermicompost + 75% of RDF of NPK; T6= 20t/ha FYM + 100% of RDF of NPK + bio fertilizer (Azotobactor + phosphate solubalizing bacteria or PSB); T7= 30t/ha FYM + 75% of RDF of NPK + bio fertilizer; T8= 5 t/ha Vermicompost + 100% of RDF of NPK + bio fertilizer; T9= 7.5 t/ha Vermicompost + 75%NPK + bio fertilizer. The result revealed that all the growth and yield characteristics are significantly affected by different levels of organic and inorganic treatment combination. With respect to different plant growth parameters like plant height, total no of leaf, D-leaf initiation days, D-leaf length, D-leaf width and plant grith found effective with treatment combination T9 (7.5t/ha vermicompost + 75% RDF of NPK + bio fertilizer). Among all the treatment received 7.5t/ha vermicompost, 75% RDF of NPK and bio fertilizer recorded the highest flowering and fruiting, maximum estimated yield along with better nutrient uptake. From different treatment combinations on FYM, NPK and bio fertilizer, it can be concluded that Growth and yield is faster in nutrient applied plants especially were organic and inorganic nutrients has been applied with biofertilizers.
