An experiment has been conducted during the Rabi of 2020-21 with following objectives, to study the growth behaviour of wheat under different organic and inorganic sources of Nitrogen and to assess the economics of each the treatments. The following treatments namely Recommended dose of fertilizer (RDF) 120:60:40, RDF 100 % + FYM 2.5 t ha-1, RDF 100 % + FYM 5 t ha-1, RDF 100 % + FYM 7.5 t ha-1, RDF 100 % +FYM 10 t ha-1, RDF 100 % + FYM 15 t ha-1, 125 % of RDF and 150 % of RDF have been used under this experiment. The studies revealed that the initial population of plants, height and various other morphological parameters were superior in case of RDF 100 % + FYM 15 t ha-1 followed by Recommended dose of fertilizer (RDF) 120:60:40 and RDF 100 % +FYM 10 t ha-1. The greater economics was recorded in recommended dose of fertilizer (RDF) 120:60:40 followed by RDF 100 % + FYM 5 t ha-1 and RDF 100 % + FYM 2.5 t ha-1.
