Abstract: A field field experiment was conducted during 2013-14 and 2014-15 at research farm, RVSKVV, College of Agriculture, Gwalior, Madhya Pradesh. The experiment involve thirty treatment combinations consisting of two varieties viz. V₁: RVW 4106 and V₂: MP 4010 as well as three seed rates viz. S₁: 100 kg/ha; S₂: 125 kg/ha and S₃: 150 kg/ha and five fertility levels i.e. F₁: 50% RDF + 10 tonnes FYM/, F₂: 75% RDF + 5 tonnes FYM/ha, F₃: 100% RDF, F4: 125% RDF and F₅: 150 % RDF in factorial R.B.D with 3 replications. The result revealed that plant population were non-significant in respect to varieties and fertility levels whereas seed rate of 150 kg/ha recorded significant with higher plant population as compare to others. Among the varieties, MP-4010 resulted the higher values of all these characters. Seed rate also had a significant effect on plant height at all the stages. Seed rate of 150 kg/ha recorded significantly effect on plant height at all the stages. Significantly higher number of leaves was recorded with 125 kg/ha seed rate followed by 150 kg/ha. In case of dry weight per plant, Lower seed rate (100 kg/ha) significantly produced maximum dry weight at 60 DAS and at maturity stage while at 60 DAS. Highest plant dry weight was obtained with 125 kg/ha seed rate whereas the application of 150% RDF recorded significantly higher plant height. The other growth characters viz. number of leaves, dry weight per plant were higher under the fertility level of F₂:75% RDF + 5 tonnes FYM /ha. Variety MP-4010 with seed rate 125kg/ha under 75% RDF + 5 tonnes FYM /ha gave the maximum net income of Rs. 64581 /ha as compared to the other treatment combinations. The minimum net monetary return obtained by F₁S₁V₁ (Rs 42433 /ha). Amongst the varieties, MP 4010 recorded the more net income (Rs. 56407/ha) with B:C ratio 3.03 as compared to RVW 4106. Amongst seed rate, crop sown with 150kg/ha seed rate gave highest gross and net income followed by seed rate 125 kg/ha whereas maximum B:C ratio was recorded with 125kg/ha. However, fertility levels of F₂:75% RDF + 5 tonnes FYM/ha recorded the highest net income (Rs. 59536/ha) and B:C ratio (3.16).
