Abstract

This experiment was carried out in Randomized block design with Three replication and 10 treatments combination at Crop Research Centre-II, ITM University, Gwalior (M.P) During the Rabi season of 2022-23 entitled “Effect of Integrated Nutrient Management on growth, yield attribute and yield of lentil” (Lens culinaris L)”. The treatments consist of T1 – Control, T2 – 100% RDF (20:40:0 NPK), T3 – 75% RDF + Vermicompost @2.5t/ha, T4 – 75% RDF + Rhizobium, T5 – 75% RDF + PSB, T6 – 75% RDF + Rhizobium + PSB, T7 – 50% RDF + Vermicompost @2.5t/ha + Rhizobium + PSB, T8 – 75% RDF + Vermicompost @ 1.5t/ha + Rhizobium + PSB, T9 -100% RDF + Vermicompost @ 1t/ha + Rhizobium + PSB. T10 – 125% RDF +vermicompost @ 0.5t/ha + Rhizobium + PSB. and each treatment were replicated thrice. and seeds were treated with Rhizobium and PSB. The INM practices Significantly affected the yield and yield attributes parameters like no. of pods /plant, pod length (cm), no of grains/pods, 1000 seed weight, grain yield (kg/ ha), stalk yield (kg/ha), biological yield (kg/ha) and harvest index (%) was recorded under the treatment (T10-125% RDF + vermicompost @ 0.5t/ha + Rhizobium + PSB) but it was at par with (T9 -100%RDF +vermicompost @1t/ha + Rhizobium + PSB), (T8 - 75%RDF + vermicompost @1.5t/ha + Rhizobium +PSB) and at par with rest of the treatments. and minimum yield parameters was recorded under control.
