Influence of integrated nutrient management on yield and bio-chemical parameters of pineapple (cv. Kew)

Abstract

The present investigation entitled “Effect of Integrated Nutrient Management on Yield and bio-chemical parameters of Pineapple (cv. Kew)” was conducted with the objective to understand the better utilization of nutrients for yield and quality at Horticulture farm under Department of Horticulture and Post Harvest Technology, Institute of Agriculture, Visva Bharati, Sriniketan during 2014-2016 which consisted of nine treatment combinations viz., T1= Control; T2= 20t/ha FYM + 100% of recommended dose of fertiliezer (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 + biofertilizer (Azotobactor + phosphate solubalizing bacteria or PSB); T7= 30t/ha FYM + 75% of RDF of NPK + biofertilizer; T8= 5 t/ha Vermicompost + 100% of RDF of NPK + biofertilizer; T9= 7.5 t/ha Vermicompost + 75%NPK + biofertilizer. On the basis of result findings it may be concluded that the use of vermicompost along with the combination of NPK and biofertilizer has found to be the best and beneficial for obtaining higher yield in pineapple (cv. Kew). The studies emphasize the application of 30t/ha FYM + 75% RDF of NPK + biofertilizer as best treatment in terms of maintaining fruit bio-chemical parameters of pineapple.
