Chhapka . All the varieties were sown in the 16 September and harvested at complete maturity. The recommended agronomical practices were followed in raising of Indian mustard cultivars as suggested by Singh and Rathi (1985). The irrigations were given to crop as and when required. The farmers were advocated for the assessment of seed yield but the growth, yield traits and economic study done by scientific team. The yield data was collected from the farmers and statistically analyzed as suggested by Gomez and Gomez (1984). III. R esults and D iscussion The growth, yield traits, seed yield and economic data were statistically analyzed and reported in Table-1 and discussed here under appropriate heads. a) Effect of early sowing on growth parameters The different varieties of Indian mustard did not much differ in plant height. The lowest primary branches was counted in local variety of Chhapka and other tested varieties displayed at par branches/plant. The insignificant response was recorded in production of siliquae/plant under different cultivars. The similar trend was also noted in weight of siliquae/plant (Table -1). The similar results have also been reported by Singh et al. (2019). b) Effect of early sowing on yield traits The lowest seed weight/plant was weighed in local cultivar Chhapka by 15.85 gram/plant and highest was found in cultivar Urvarshi (18.00 g/plant), but insignificant response was found under different tested varieties at early stage sowing. The lowest test weight of 4.30 g was noted under local cultivar Chhapka , while highest test weight by 4.95 g was recorded under cv. Urvarshi . The other varieties displayed the test weight values under these two limits. These results confirm the finding of Singh et al . (2019). c) Effect of early sowing on seed yield (q/ha) Results displayed that all the high yielding varieties were found effective in order to increase of seed yield of Indian mustard over local cultivar Chhapka (Table-1). The maximum increase in seed yield was recorded in cultivar Urvarshi (15.10 q/ha) closely followed by Rohani (11.65 q/ha) and Pusa Jai Kisan (11.30 q/ha) over local cultivar Chhapka under early sowing period. The cultivars Urbashi increased the number of siliquae/plant, weight of seed/plant and 1000- seed weight which were responsible for increasing the seed yield of Indian mustard. It is also worthwhile to mention here that the severe density of fog and frost during pod filling stage did not influence to the seed yield of Urvarshi . Therefore, cultivar Urvarshi proved thermo resistant cultivar and registered higher yield over local Chhapka and other improved cultivars. These results are commensurable to the findings of Singh et al. (2019) d) Economic study The gross return (Rs. 138600/ha), net return (Rs. 99667/ha) and BCR (1:3.56) were recorded higher in cv. Urvarshi as compared to other improved cultivars including local Chhapka . The lowest gross return (Rs. 70650/ha) net return (Rs. 31717/ha) and BCR (1:1.81) were computed under local variety Chhapka . The varietal performance was Urvarshi (Rs. 99667/ha) > Rohani (Rs. 84142/ha) > Pusa Jai Kisan (Rs. 82567/ha) > Varuna (Rs. 81442/ha) > Kanti (Rs. 80317/ha) and > Chhapka (Rs. 31717/ha). The higher and lower seed yield of different varieties were responsible for highest and lowest net income. The variety Urvarshi also increased net income of farmers by 3.15 fold which was higher over other tested varieties. IV. C onclusion On the basis of experimental results, the farming community of South-Western and Central tracts of Uttar Pradesh may be advocated for sowing of cultivar Urvarshi in early planting period to obtain the higher seed yield, net income and more than three fold net income. Farmers Reaction The locality and visiting farmers appreciated the efforts of scientists and they followed the smart agronomy in cultivation of cv. Urvarshi of Indian mustard as suggested. Feed Back The demand of Urvarshi seed increased among farmers due to thermo-resistant, and resistant to fog and frost. R eferences R éférences R eferencias 1. Anonymous, 2012.
