The field investigation was conducted at Regional Research Centre, Amravati under Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during Kharif 2020-21 to 2022-23. The experiment was laid out in a Factorial Randomized Block Design with twelve treatments combinations (Factor A: Varieties-V1: AMS 1001 (PDKV Yellow Gold), V2: AMS-MB 5-18 (Suvarn Soya), V3: AMS 100-39 (PDKV Amba) and V4: JS 93-05 and Factor B: Seed rate-S1: 50 kg ha-1, S2: 62.5 kg ha-1 and S3: 75 kg ha-1) with three replications.
From pooled data over the three years revealed that, variety AMS-100-39 (PDKV Amba) showed significantly superior over rest of the varieties in respect of seed yield (2403 kg ha-1), straw yield (2903 kg ha-1) and also recorded higher gross monetary returns (Rs.101748 Rs ha-1), net monetary returns (60734 Rs ha-1) and B:C ratio (2.48). Seed rate 62.5 kg ha-1 was found significantly superior over all other seed rate i.e. Seed rate 50 kg ha-1 and seed rate 75 kg ha-1 in respect of seed yield (2296 kg ha-1), gross monetary returns (96941Rs ha-1), net monetary returns (55964 Rs ha-1) and B:C ratio (2.37). Pooled results revealed that in variety x seed rate interaction, variety AMS-1001 (PDKV Yellow Gold), AMS-MB 5-18 (Suvarn Soya) and AMS 100-39 (PDKV Amba) recorded higher seed yield, straw yield, gross monetary returns and net monetary returns with seed rate 62.5 kg ha-1.
