Popularization of improved maize (Zea mays L.) production technology through frontline demonstrations in semi arid zone IVA of Rajasthan
Journal Title: Journal of Applied and Natural Science - Year 2014, Vol 6, Issue 2
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.
