Abstract:

Maize is the most important world’s leading cereals crop which can be grown in diverse seasons, ecological and uses and known as queen of cereal due to unparallel productivity among cereal crops. Front line demonstrations (FLDs) on maize were laid down at 180 farmers’ fields to demonstrate production potential and economic benefits of improved production technologies comprising high yielding varieties namely PEHM-2, PM-3, PM-5, PSM 2 and PM 4 in Pali district of arid zone of Rajasthan state during Kharif seasons from 2011 to 2017 in rainfed farming situation. The improved production technologies recorded an additional yield ranging from 3.10 to 9.9 q/ha with a mean of 6.6 q/ha. The per cent increase yield under improved production technologies ranged from 24.4 to 52.1 (PM-3), 29.6 to 57.1 (PM-5), 16.4 to 36.4 (PEHM-2), 41.8 to 58.4 (PM-4) and 29.6 (PSM-2) in respective years. The average extension gap, technology gap and technology index were 6.6q/ha, 13.4q/ha and 36.9 per cent, respectively in different varieties of maize. The improved production technologies gave higher benefit cost ratio ranging from 2.7 to 4.8 with a mean of 3.3 compared to local checks (2.0) being grown by farmers under locality. From the result of the findings that the maximum number of the respondents had medium level of knowledge and extent of adoption regarding recommended maize production technology. The study reported lack of suitable HYV as major constraints by beneficiaries is rank first followed by low technical knowledge. 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.
