A field experiment was conducted at the research farm of BTC collage of agriculture and research station, Bilaspur, Chhattisgarh during rabi season of 2019-20 with a view to study and evaluate the influence of chemical fertilizers in combination with organic manure like FYM. The mustard variety Chhattisgarh sarson was used to grown and treatment were replicated three times in completed randomized block design. The investigation carried in nine treatment viz., T1 :- 100% RDF, T2:- 75% RDF +25% FYM, T3 :- 50% RDF + 50% FYM, T4:- 100%+20 kg S, T5:- 75%RDF +25% FYM+40% S, T6 :- 50%RDF +50% FYM +20 kg S, T7:- 100% RDF +30kg S, T8 :-75% RDF +25% FYM+ 30 kg S and T9:- 50% RDF +50% FYM +30 kg S. the outcome of the investigation reveals that growth attributes viz., Plant population/m2 at 30 DAS, Plant height at 30, 60, 90 DAS, Dry weight of plant at 30, 60, 90 DAS, Number of branches/plant at 60 DAS, Crop growth rate 30-60, 60-90 DAS, Relative growth rate 30-60, 60-90 DAS. In mustard crop cultivated under Chhattisgarh plain condition. The treatment T3 (50% RDF +50% FYM) showed significantly lower values for all of the above mentioned parameters. The treatment T7 (100% RDF +30kg S) resulted the higher values for all of the above mentioned parameters. Treatment T7 (100% RDF +30kg S) also come up with highest gross return (Rs. 81340.43/ha) and it was recorded at par with T4 (100% RDF +20 kg S). The lowest or negative gross return (Rs.61010.84) and benefit cost ratio (B: C ratio) (2.69) were recorded in the treatment T3 (50% RDF +50% FYM).
