Abstract

A field experiment was conducted during the winter season of 2018 and 2019 at district seed farm, under the aegis of Bidhan Chandra Krishi Viswavidyalaya in upland situation. The experiment comprised of twenty four treatments combina-tions, which was laid out in split- plot design (factorial) with three replications. Treatments include different varieties (viz. HD 2967, DBW 39 and K 1006), and various tillage options (viz conventional tillage (CT), reduced tillage (RT) and zero tillage (ZT)), were allocated to main plots and different dose of recom-mended dose of fertilizer (viz. 50, 75, 100 and 125 % RDF) to sub-plots. K 1006 registered more grain yield (3,876 kg/ha) and significantly better to other tested cultivars. This cultivar increased grain yield to the tune of 5.59 and 11.23 %, more over HD 2967 and DBW 39. Reduced tillage (3,901 kg/ha) registered more grain yield and statistically superior to other treatments. This tillage practice reg-istered 11.10 and 21.15 %, more grain and straw yield over conventional tillage practices. Highest grain yield achieved with 125 % RDF (4,079 kg/ha) and was at par with the 100 % RDF (3,965 kg/ha), and statistically better to other treat-ments. Total nutrient uptake highest registered with the 125 % RDF, and was at par only to 100% RDF for phosphorus and potassium uptake only. Economics revealed that, K 1006 gave highest net return (Rs. 45,343 kg/ha) and fetch better B: C ratio (2.12) and was followed by cultivar HD 2967. More net profit (Rs 47,002 kg/ha) and B:C ratio (2.16) observed with reduced tillage option and quite better to other resource conservation techniques. Use of 125 % RDF gave more return of Rs. 52,301 kg/ha and was followed by full dose of recommended fertilizer (Rs. 50,985 kg/ha). Moreover more BCR of 2.18 observed with 100 % RDF and was followed by 125% RDF.
