The study were conducted by cluster frontline demonstrations (CFLD) on mustard
during 2018-2021 in the eleven villages covering 250 farmers and 100 ha area of Banka
district of Bihar to evaluate the technological interventions, yields and economic
feasibility. Yield parameters i.e., plant height, primary, secondary branches/plant,
siliqua/plant, seeds/ siliqua, siliqua length, dry matter/plant and 1000-seed weight were
recorded 219, 4.3, 13.8, 743, 13.5, 5.2, 123 and 5.7, respectively in mustard cv. RGN-
48 along with improved practices in comparison to the farmers’ practices. Significantly
higher grain yield (1508 kg/ha) (was recorded under demonstrated plots over farmers’
practice Extension gap (3.92), technology gap (11.30), technology index (42.82%) and
adaptation rate (38.33%) were markedly recorded under the demonstration plot than
farmers’ practice. Similarly gross (Rs. 66820) and net returns (Rs. 41250) obtained in
demonstration plots than farmer’s plot.
