Abstract : Front line demonstrations (FLD,s) on maize (Zea mays L.) were laid down at 661 farmers’ fields to demonstrate
production potential and economic benefits of improved production technologies comprising high yielding varieties
namely PM-3, PM-5, PEHM-2, Bio- 9681 and Mahyco 3765 in Rajsamand district of Semi Arid Zone IVa of Rajasthan
state during kharif seasons from 2006 to 2012 in rainfed farming situation. The improved production technologies
recorded an additional yield ranging from 2.50 to 15.78 qha-1 with a mean of 7.94 qha-1. The per cent increase yield
under improved production technologies ranged from 33.17 to 68.16 (PM-3), 14.09 to 59.82 (PM-5), 46.61 to 66.97
(PEHM-2), 55.83 to 92.82 (Bio 9681) and 80.12 (Mahyco 3765) in respective years. The average extension gap,
technology gap and technology index were 9.10 qha-1, 5.94 qha-1 and 20.08 per cent, respectively in different varieties of
maize. The improved production technologies gave higher benefit cost ratio ranging from 1.28 to 3.00 with a mean
of 2.45 compared to local checks (1.10) being grown by farmers under locality. The productivity of maize per unit
area could be increased by adopting feasible scientific and sustainable management practices with a suitable variety.
Considering the above facts, frontline demonstrations were carried out in a systematic and scientific manner on
farmer’s field to show the worth of a new variety and convincing farming community about potentialities of improved
production management technologies of maize for further adoption by the farming community.
