Impact of Cluster Frontline Demonstration on Yield of Chickpea in Nalanda, Bihar
Impact of CFLD on Yield of Chickpea production
Abstract
The yield gaps between cluster frontline demonstration (CFLD) and Farmers practice extent of technology adoption and extension gap. Krishi Vigyan conducted cluster Frontline demonstration on chickpea, Kendra, Nalanda, Bihar during the year 2015-16, 2016-17, and 2017-18 in 16, 07 and 2 villages, respectively. Results of CFLD reveals that the variety (GNG 1581) recorded the highest grain yield (19.78q/ha). It was 23 percent higher over the farmer practice (16.12q/ha). An average yield of 18.60q/ha was recorded in cluster frontline demonstration and in farmer practices, it was just 14.73 q/ha. Thus,the average technology gap, extension gap and technology index of 5.39 q/ha, 4.60 q/ha and 23.67 percent, respectively were obtained between demonstration and farmer practices. The average yield of chickpea increased 26.66 percent over farmer practices, while the year wise variation in yield increased from 17.00 to 40.00 percent.
The correlation and path coefficient analysis were studied in forty genotypes of dahlia for thirteen different quantitative and qualitative characters. The results indicated a significant and desirable correlation between flower yield per hectare with the characters like plant height at 120 DAT (0.614), number of branches per plant at 120 DAT (0.806), inter nodal length at 120 DAT (0.239), duration of the crop (0.195), flower weight (0.206), flower diameter (0.224), stalk length (0.549), number of tubers per plant (0.537), tuber weight (0.453) and vase life (0.234). This provides a knowledge regarding association of various characters among themselves and to estimate the inherent association between genes. Path analysis has shown that number of flowers per hectare had high positive direct effect with plant height at 120 DAT (0.962), number of days taken to first flowering (0.646), flower weight (1.034), stalk length (0.253), number of tubers per plant (0.353), tuber weight (0.194) and vase life (0.285) at genotypic level. Thus, these characters have maximum contribution towards the number of flowers per hectare.
