The present investigation entitled to evaluate the effect of nutrient management on the growth and productivity of wheat (Triticum aestivum L.) in the red and lateritic belt of West Bengalwas carried out during rabi season of 2011-12 at Agricultural farm of Palli Siksha Bhavana, Visva-Bharati, Sriniketan (West Bengal). Integrated use of biofertilizers in combination with the chemical fertilizer and their proper management for better productivity and economics is very essential. Keeping, these facts in perspective, the present investigation were taken up. The experiment consisted of the five levels of fertilizer i.e. control, 50 % RDF, 75 % RDF, 100 % RDF and 125 % RDF and four levels of biofertilizers viz. no biofertilizers, Azotobacter, Phosphorus solubilizing bacteria (PSB) and combined application of Azotobacter and PSB thus making twenty treatment combinations which were replicated thrice and was laid out in factorial randomized block design (FRBD). The Recommended dose of fertilizer (RDF) was 100:50:50 kg/ha of N: P2O5:K2O. The maximum values for growth parameters like plant height, dry matter accumulation and leaf area index were observed in 125 % RDF and Azotobacter +PSB and similar effect was observed yield attributes and yield. The total nutrient uptake of wheat was recorded highest in the 125% RDF + Azotobactor + Phosphate Solubilizing and The lowest value in recorded in Control. This indicated that the wheat crop responded upto 125 % RDF and combined application of Azotobacter and PSB proved superior over application of Azotobacter only but was statistically at par in most of the cases with application of PSB alone.
