Major gap was observed between improved technology and farmer’s practice of chickpea cultivation in Bharatpur district of Rajasthan (Table 1). Among varying technological component, full gap was observed in the component
viz., variety and seed treatment by liquid bio-fertilizers and partial gap was observed in seed rate, seed treatment by chemical fungicide, fertilizer management and plant protection measures. These gaps observed at the farmers’ field are ascribed to the slow pace of extension activities; coupled with unreached extension system, poor accessibility of advanced or improved agro-technologies especially among small holder farmer’s
(Shivran et al., 2020). Under farmer’s practice, seed of local/old variety with low yield potential was sown instead of newly recommended varieties for the zone with improper application of improved recommended package technologies. On the basis of observed gap, under the demonstration, improved variety (GNG 1581, RSG 895, CSJ 515, RSG 974), fungicide, insecticide and bio-fertilizer (
Rhizobium and PSB culture) were provided to the partner farmers by KVK and other component
viz., chemical fertilizers and all other crop management practices were timely performed by the partner farmer itself under the supervision of KVK Scientist. Similar findings have also been observed by
Meena et al., (2021), Saikia et al., (2018), Bhargav et al., (2017) and
Meena and Singh (2017).
Chickpea yield
Under National Food Security Mission (Pulses), total of 350 cluster frontline demonstrations of chickpea were demonstrated during 2016-17 to 2019-20 in agro-climatic zone of Bharatpur. The findings obtained during last four years of demonstrations are presented in Table 2 which revealed that average yield of chickpea through improved technology ranged from 11.83 to 17.52 q/ha as compared to 9.85 to 14.40 under farmer’s practice. Average yield of total 350 demonstrations was 14.47 q/ha from improved technology whereas, the average yield from farmer’s practices was 11.97 q/ha. Under improved technology, it recorded 19.39 to 22.77 per cent increased in yield over the local check. Thus, there was on an average 20.95 per cent increase in demonstration yield over local check. Demonstrated chickpea variety CSJ-515 gave the highest yield (17.52 q/ha) during the year 2018-19. The results also revealed that yield under improved technology as well as under farmer’s practices were higher than the district and State average yield during all the years of demonstrations. The higher yield of chickpea could be attributed due to adoption of improved variety with improved production practices of chickpea. These results corroborate the findings of
Reager et al., (2020) and
Meena et al., (2020) and Meena and Singh (2017) in green gram,
Wadkar et al., (2018) in chickpea. However, on an average, 6.30 q/ha higher yield of chickpea was recorded under improved technology over district average. Similarly, 3.73 q/ha higher yield of chickpea was recorded under improved technology over State average. It was due to use of high yielding improved variety, improved agronomic practices and adoption of improved management practices.
Meena et al., (2021) and
Shivran et al., (2020) also reported the higher grain yield of chickpea and Indian mustard respectively, under front line demonstrations over district and state average.
Technology gap
The data of Table 2 depicted the technology gap in demonstration yield against potential yield which ranged from 2.48 to 10.28 q/ha during different years of demonstration. Technology gap was maximum (10.28 q/ha) during 2016-17 and minimum (2.48 q/ha) during 2018-19. On an average technology gap during four years of demonstrations were 627.75 kg/ha for chickpea cultivation in Bharatpur district. This also reflects the poor extension activities, which resulted in lesser adoption of package of practice by farmer. Hence, extension activities and a location specific technological recommendation appear to be necessary to decline the technology gap. These results corroborate the findings of
Meena et al., (2021) and
Jat et al., (2013).
Extension gap
Extension gap is considered as a parameter to know the yield difference between the demonstrated improved technology and farmer’s practices. Results of the demonstrations (Table 2) stated that the extension gap ranging between 1.98-3.12 q/ha was found between demonstrated technology and farmer’s practices. On an average extension gap during period of study was 250.75 kg/ha. So as to enhance the farmers income, there is need to reduce the wider extension gap, therefore, it is necessity to educate the farmers through various means for more adoption of recommended improved high yielding varieties and implementation of latest agro-technique
(Reager et al., 2020, Meena et al., 2020 and
Meena and Singh (2017) in green gram and
Meena et al., (2021) in chickpea.
Technology index
The technology index is a parameter to show the feasibility of the improved technology at the farmer’s fields. Data on technology index presented in Table 2 shows that technology index varied from 12.40 to 44.69 per cent. During study period of frontline demonstrations, highest technology index 44.69 per cent and lowest 12.40 per cent was recorded during year of 2016-17 and 2018-19, respectively. Further, on an average technology index 29.71 per cent was observed during four experimental years of chickpea, which shows the efficacy of good performance of technical interventions. This will accelerate the adoption of demonstrated technological intervention to increase the yield performance of chickpea at farmer’s field. Similar findings were recorded by
Meena et al., (2021), Reager et al., (2020), Wadkar et al., (2018), Bhargav et al., (2017) and
Jat et al., (2013).
Economics
Economics of improved technology under frontline demonstration were estimated (Table 3) on the basis of prevailing market rates which recorded higher gross monetary return (Rs. 80942/ha), additional returns (Rs.14414/ha.) with improved technology demonstration compare to farmer’s practice in the year 2018-19 in case of chickpea variety CSJ-515. The higher net returns (Rs. 58373/ha), effective gain (Rs. 11529/ha) and B: C ratio (4.11) with improved technology demonstration compare to farmer’s practice in the year 2019-20 in case of chickpea variety RSG-974. Seed yield, cost of variable inputs, labour charge and sale price of produce determine the economic return and these vary from year to year. The present investigation showed improved technology fetched higher net return to the tune of Rs. 26245/ha to Rs. 58373/ha with the average of four years (Rs. 46618/ha). However, under farmer’s practice, the net return ranged from Rs. 20345/ha to Rs. 46844/ha over the years and its average value fetched to Rs. 36737/ha. Further, on the average, of all four years of study revealed that improved technology demonstration gave higher mean gross return (Rs. 68836/ha), mean net return (Rs. 46618/ha), mean additional returns (Rs. 11956/ha), mean effective gain (Rs. 9881/ha) and mean B:C ratio (3.10) compare to farmer’s practice. Similar economic benefits owing to adoption of improved technology interventions were also reported by
Meena et al., (2021), Reager et al., (2020), Meena et al., (2020) and
Jat et al., (2013).
