A field experiment was carried out during rabi season in December 2021-May 2022 at the Crop Research Center Department of Soil Science and Agriculture Chemistry, School of Agriculture, ITM University, Gwalior, Madhya Pradesh, to investigate the effect of different levels of N, P and K fertilizers with biofertilizers on growth, dry matter accumulation and yield of Chilli (Capsicum annum L.) in Alluvial soil of Gwalior, Madhya Pradesh. The experiment was laid out in randomized complete block design with three replications. The experimental treatments comprised nine NPK with biofertilizers combinations as control, (no nutrient added) 50% RD of NPK, 75% RD of NPK, 100% RD of NPK, 50% RD of NPK with N-fixer, 50% RD of NPK with Aspergillus niger, and 50% RD of NPK with N-Fixer & Aspergillus niger, 75% RD of NPK with N-fixer, 75% RD of NPK with Aspergillus niger, and 75% RD of NPK with N- Fixer & Aspergillus niger. Growth and yield significantly influenced by different doses of NPK with biofertilizers. Application of 75% RD of NPK with N- Fixer & Aspergillus niger) produced the tallest plant height maximum dry matter production at harvest^-1), highest green chilli and stover yield of chilli (122.54 q ha^-1 and 14.38 qha^-1). Based on the results of this study, it can be suggested that the combined use of 75% RD of NPK with N- fixer + Aspergillus niger increased plant growth and fruit yield of chilli.
