Assessment of Different Cultivars of Chickpea (Cicer arietinum) Under Cluster Front Line Demonstration Programme in Changing Climate Variability in Samastipur District, Bihar, India | Chapter 7 | Research Advances and Challenges in Agricultural Sciences Vol. 2

The study introduced and evaluated two chickpea varieties, namely, BGM-547 and GNG-1581. Nutrient management plays a pivotal role that greatly affects the growth and yield of chickpea because this crop does not suit well to warm climate. The pulse cultivation has been drastically reducing in recent years mainly due to less and irregular precipitation during monsoon and reduction in winter days as this crop does not suit well to warm climate, resulting in shortage of pulses in the market. The chickpea has been most preferred pulse in Samastipur to be grown in rabi season. The present study was conducted to revive the chickpea cultivation employing new cultivars by KVK, Samastipur and carried out during rabi season in different blocks of the district during the years 2015-16, 2016-17 and 2017-18. The Cluster Front Line Demonstration on chickpea varieties, namely, BGM-547 and GNG-1581 were taken up during each year for 15, 33 and 18 clusters, respectively. These demonstrations recorded higher average grain yield (13.75, 14.60 and 14.40 q/ha) of chickpea as compared to average yield obtained from farmers’ practice (12.5, 9.47 and 11.73 q/ha) computed to increase in yield by 9.09 %, 15.13% and 18.54 % during 2015-16, 2016-17 and 2017-18 respectively. Similarly, the benefit: cost ratio was 1.78, 2.11 and 2.08, respectively. The technology gap (q/ha), extension gap (q/ha) and technology index (%) were 6.25, 1.25 and 31.25 during 2015-16, 5.40, 5.13 and 27.00 were during 2016-17 and 9.60, 2.67 and 40.00 were 2017-18. The major differences observed between demonstration package and farmers’ practices were introduction of seed treatment with bio-fertilizer, method and time of sowing, fertilizer doses and method of its application and plant protection measures. The significant increase in yield is attributed due to introduction of new varieties in cluster mode. This mode facilitates better crop management resulting in better quality production. The study recorded a significant increase in chickpea yield compared to the average yield obtained from traditional farmer practices. The percentage increase in yield (9.09%, 15.13%, and 18.54% for the respective year) demonstrates the efficacy of the new cultivars and cultivation practices introduced. The technology gap, extension gap, and technology index provide a quantitative assessment of the impact of introducing new varieties in cluster mode. These parameters highlight the effectiveness of the new technologies in narrowing the gaps between potential and actual yield.
