TITLE

Effect of organic and inorganic fertilizers on productivity of lentil (Lens esculenta Moench)

ABSTRACT

A field experiment was planned and conducted during the Rabi season of 2019-2020 at Crop Research Center of Alpine Institute of Management and Technology, Dehradun (Uttarakhand). The experiment was conducted to evaluate the effect of organic and inorganic fertilizers on productivity of lentil (Lens esculenta Moench). The experiment was laid out in randomized block design with three replications and ten treatments. The treatments constituted viz. T₁- control, T₂- RDF, T₃- FYM, T₄- vermicompost, T₅- RDF + FYM, T₆- RDF + vermicompost, T₇- Rhizobium + PSB, T₈ RDF + Rhizobium + PSB, T₉- FYM + Rhizobium + PSB and T₁₀- vermicompost + Rhizobium + PSB. The crop variety Pant Masoor- 5 was sown on October 20, 2019 and harvested on March 01, 2020. Studies were made on growth parameters (plant height, number of branches and dry weight per plant), root nodulation, yield attributing parameters (number of pods per plant, number of seeds per pod and 100 grain weight), productivity parameters (grain yield and straw yield) and economical returns. It was concluded from the findings that integrated nutrient management having RDF + FYM increased the plant height, branches and dry weight per plant of lentil up to maximum. The application of RDF + FYM increased the root nodulation, yield attributing parameters and yield of lentil significantly higher to those of other treatments except RDF + vermicompost and RDF + Rhizobium + PSB. Amongst the integrated nutrient management treatments, RDF + FYM recorded the maximum net profit of Rs. 19,047 per hectare and B: C ratio of 1.72.
