The experiment consisted of treatments such as application of different vermicompost levels (V0, V1 and V2), bio-inoculation of seeds with Azatobactor + PSB, different fertility levels (F1, F2 and F3). The experiment was conducted in factorial randomized block design and replicated thrice. Results of field experiment revealed that application of 4 t vermicompost (V2), bio-inoculation of seed with Azotobactor + PSB (B1) and in fertility level 100 % RDF had significant effect on various growth parameter viz., plant height at harvest (V2 = 97.04, B1 = 96.27 & 100 % RDF = 97.10), dry matter accumulation (at 60 DAS, 90 DAS & harvest) and in yield parameter viz., total number of tillers at harvest, grain yield (V2 = 5210, B1 = 5155 & 100 % RDF = 5468 Kg ha -1 ), straw yield (V2 = 8104, B1 = 7901 & 100 % RDF = 8243 Kg ha -1 ) and biological yield (V2 =13314, B1 = 13056 & 100 % RDF = 13712 Kg ha -1 ) and the test weight is statistically at par with 2 t ha -1 vermicompost (V1), without inoculation of seed (B0) and 75 % RDF. Harvest index was non effected by various treatments. Keywords: Effect of vermicompost, fertility levels, yield of wheat Introduction The cruising population is now confronted by a major shortage of plant produce and there is a worldwide demand to produce high yielding quality crops to meet the ever increasing population requirements. Better soil, crop and nutrient management practices play a pivotal role to achieve this. This would narrow down the yield gap between achievable and actual yields besides furnishing valuable feedback information regarding yield sustainability. To meet the world's future food security and sustainability needs, food production must grow substantially while agriculture's environmental impact must shrink dramatically at the same time (Foley et al., 2011) [3] . The indiscriminate use of inorganic fertilizers for the past 50 years without any organic manures resulted in the large scale deficiency of micro nutrients which play an important role in enhancing the quality and quantity of the agriculture produce though their increment in enzyme system and photosynthesis. Further, nutrient loses in inorganic fertilizer is very high and loss of nutrients like NO3 sometime leads to water pollution. The integrated use of organic materials and inorganic nitrogenous fertilizers has received considerable attention in the past with a hope of meeting the farmers' economic need as well as maintaining favorable ecological conditions on long-term basis (Kumar et al., 2007) [6] . The integrated nutrient management helps to restore and sustain fertility and crop productivity. It may also help to check the emerging deficiency of nutrients other than N, P and K. Further, it brings economy and efficiency in fertilizers. The integrated nutrient management favorably affects the physical, chemical and biological environment of soils. Integrated nutrient supply involving conjunctive use of fertilizers and organic sources of nutrients (Roy, 1992) [9] assumes greater significance. The major components of organic integrated nutrient management system involves the organic manures with variable nutrient release patterns mainly compost, green manures, vermicompost, crop residue and bio-fertilizers along with natural soil reserves. Farmyard manure improves the physical condition of soil by increasing water holding capacity for maximum utilization of water. It also improves the chemical and biological condition of soil by increasing cation exchange capacity and providing various vitamins, hormones and organic acids which are very important for soil aggregation and for
